ADAS اِگزیم

Video Explanation

Explanation:

They significantly improve the active safety of the vehicle: Correct
ADAS (Advanced Driver Assistance Systems) are designed to enhance vehicle safety by helping the driver avoid accidents or reduce collision severity. These systems provide real-time assistance through sensors, cameras, and algorithms, with features such as:
Lane Departure Warning (LDW): Alerts the driver if the vehicle drifts out of its lane.
Adaptive Cruise Control (ACC): Maintains a safe distance from other vehicles.
Automatic Emergency Braking (AEB): Applies brakes if a collision is imminent.
Blind Spot Detection: Warns the driver of vehicles in blind spots.
ADAS improves active safety by assisting the driver in making safer decisions. While these systems help by providing alerts or taking actions like automatic braking.
Reduce the driver’s reaction time: While ADAS can assist the driver by providing warnings and interventions. These systems help the driver by providing alerts or taking action (e.g., automatic braking), which gives the driver more time to respond.
They allow the driver to reduce his alertness level: ADAS systems do not encourage reduced alertness. In fact, they can help by assisting with certain tasks, such as maintaining speed or staying within a lane, the driver is still required to be alert and ready to take control at any time.

Video Explanation

It makes it easier for the driver to make decisions: Correct
ADAS systems provide valuable, real-time information to the driver, which indeed makes it easier for the driver to make decisions. These systems assist in various driving tasks by providing alerts and feedback on factors such as distance from other vehicles, lane positioning, speed, and proximity to obstacles. This additional information helps the driver make more informed, timely, and safe decisions.
For example, Lane Departure Warning alerts if the vehicle drifts, Blind Spot Detection warns of vehicles in hidden areas, and Adaptive Cruise Control adjusts speed to maintain a safe distance from the car ahead.
It is irrelevant to driving: This is incorrect because ADAS is specifically designed to enhance driving safety and support the driver in making better decisions.
It is counterproductive in case of danger: This statement is incorrect because ADAS systems are designed to help in dangerous situations. For example, Automatic Emergency Braking (AEB) can take control of the brakes to prevent a collision, and Collision Warning alerts the driver to potential risks. These systems act to reduce the risk of danger, not make it worse.

Video Explanation

Reduce emissions and vehicle consumption: Correct
The Start-Stop system automatically shuts off the engine when the vehicle is at a complete stop and restarts it when the driver releases the brake or presses the accelerator. This system helps achieve the following positive effects:
Reduce emissions: By turning off the engine during idling, it reduces fuel consumption and harmful emissions, such as CO2, making the vehicle more environmentally friendly, especially in urban traffic conditions.
Reduce vehicle consumption: The engine is not running when the vehicle is stationary, leading to lower fuel usage, especially in city driving where the vehicle might idle for long periods.
Brake the vehicle at a stop sign: The Start-Stop system does not control braking; it only shuts off and restarts the engine.
Reduce vehicle consumption, only: While it reduces fuel consumption, but it also helps reduce emissions, improving the vehicle’s environmental impact.

Video Explanation

Yes, permanently or temporarily: Correct
ADAS (Advanced Driver Assistance Systems) in most vehicles can be deactivated temporarily or permanently, depending on the system and vehicle model. Here’s why:
Temporarily: Most ADAS systems, such as Lane Departure Warning (LDW), Adaptive Cruise Control (ACC), and Collision Prevention Systems, can be temporarily turned off by the driver via vehicle settings or dashboard/steering wheel controls. These systems can be reactivated when needed.
Permanently: Some ADAS systems can be permanently deactivated through professional intervention, such as software updates, modifications, or hardware changes.
They can be disconnected permanently but never temporarily: This is incorrect. Most ADAS systems can be temporarily turned off by the driver for manual control or specific driving conditions.
They can not be disconnected in any case: This is also incorrect. ADAS systems can be temporarily disabled by the driver, and some may be permanently deactivated through professional services, though this is less common and may be regulated.

Video Explanation

AEB or Urban and Interurban Emergency Braking: Correct
Aptitude and behavior control tests for obtaining a driving license may allow certain ADAS systems to assist the driver, but these systems do not replace the driver’s responsibility.
AEB (Automatic Emergency Braking): Permitted during driving tests in many regions, AEB automatically applies brakes when an imminent collision is detected, reducing accident severity or preventing it. It is a safety aid, not a substitute for driving skills, aligning with the test’s focus on road safety.
Urban and Interurban Emergency Braking: A variation of AEB designed for city (urban) and highway (interurban) driving, assisting in emergencies like rapid approach to another vehicle.
Parking Attendant: Parking Assist systems help with steering and braking during parking but are not allowed in driving tests as these assess the driver’s manual parking skills and vehicle control.
Traffic Sign Recognition (TSR): TSR displays road signs, such as speed limits, but does not actively assist in driving safety like AEB.

Video Explanation

Through a sensor that detects the angle of inclination of the vehicle and prevents it from going backwards when the brake foot is lifted: Correct
The Hill Start Assist (HSA) system helps drivers start on an incline by preventing the vehicle from rolling backward.
How it works: When on a slope, HSA detects the incline angle and keeps the vehicle stationary briefly after the brake is released. It holds the brakes momentarily, ensuring a smooth transition from stopping on a hill to moving forward.
It rapidly revives the engine to prevent the vehicle from rolling backwards when you release your foot from the brake: It is incorrect. HSA does not increase engine speed but holds the brakes to prevent rollback, not altering RPM.
It will apply the parking brake automatically and will not release it untill the driver presses the accelerator, thus preventing the vehicle from rolling backwards: It is incorrect. HSA uses the regular brakes, not the parking brake, to keep the vehicle stationary temporarily.

Video Explanation

When a sensor detects a decrease in visibility: Correct
An automatic lighting system uses sensors to detect ambient light levels. When visibility decreases—such as in tunnels, at dusk, or during adverse weather—it automatically activates the headlights, ensuring adequate lighting without manual adjustment.
Starting at a certain time: It is incorrect. The system activates based on real-time visibility conditions, not a specific time of day like sunset.
When a sensor detects that the driver is fatigued: It is incorrect. Automatic lighting systems do not monitor driver fatigue. Fatigue detection systems are separate and focus on driver behavior, not lighting adjustments.

Video Explanation

Advanced Emergency Braking system: Correct
AEB is a key component of ADAS, designed to automatically apply brakes when an imminent collision is detected. Using sensors, cameras, or radar, it monitors the road for vehicles, pedestrians, or obstacles. If a potential collision is identified and the driver does not respond in time, the system intervenes by applying brakes to reduce crash severity or avoid it altogether.
A system that holds the vehicle on steep downgrades: It is incorrect because this describes hill descent control, which is unrelated to AEB.
An Advanced Electronic Anti-lock Braking System: It is incorrect because this refers to ABS, which prevents wheel locking during emergency braking. While both enhance braking safety, AEB and ABS are distinct systems with different purposes.

Video Explanation

Warning the driver that there is a risk of collision: Correct
AEB enhances road safety by assisting the driver when a collision risk is detected. Here’s how it works:
Warning the Driver: When a collision risk is detected, AEB alerts the driver with audible, visual, or tactile warnings, giving the driver time to react.
Partial or Full Braking: If the driver doesn’t respond, AEB automatically applies partial or full braking to reduce or avoid the collision.
Taking control of the vehicle when it detects an increase in the front safety distance: It is incorrect because AEB activates when the safety distance decreases, signaling a potential collision.
Taking control of the vehicle’s direction and performing an evasive manoeuvre: It is incorrect because AEB does not control direction or evasive maneuvers; this is handled by systems like Automatic Emergency Steering (AES).

Video Explanation

Warning the driver and if he ignores it, taking control of the vehicle to stop it: Correct
AEB enhances safety by assisting the driver when a collision risk is detected. Here’s how it works:
Warning the Driver: When a collision risk is detected, the system alerts the driver with audible, visual, or tactile signals, giving the driver time to react.
Taking Control if Necessary: If the driver fails to respond, AEB automatically applies the brakes to reduce the collision’s severity or avoid it altogether.
It will act by taking control of the direction of the vehicle and performing an evasive manoeuvre: It is incorrect because AEB only applies the brakes, not controls the vehicle’s direction or evasive manoeuvres. Directional control is managed by other systems like AES.
It will emit rapid flashing stop lights when the brakes are applied hard in an emergency situation: It is incorrect because Flashing brake lights may be present in some vehicles, but this is not part of the AEB system, which focuses on collision detection and braking.

Video Explanation

Explanation:

It will emit an audible and/or visual warning when it detects an approaching vehicle: Correct
The Cross-Traffic Alert system enhances safety by using radar sensors to detect approaching vehicles, pedestrians, or cyclists from the sides while reversing. When a potential hazard is detected, the system alerts the driver with audible beeps and/or visual signals (such as indicators on the infotainment screen or side mirrors), giving the driver time to react.
It will help the driver avoid the obstacle at the same moment it detects it: It is incorrect because the system does not actively steer or manoeuvre the vehicle to avoid obstacles. It is strictly a warning system.
It will take control of the vehicle, stopping it immediately when it detects an approaching vehicle: It is incorrect While some systems may combine Cross-Traffic Alert with Automatic Emergency Braking (AEB), this feature is not standard in most Cross-Traffic Alert systems. It only provides warnings.

Video Explanationn

Explanation:

When breaking out of a parking space, it detects a vehicle approaching crosswise and there is a risk of a collision: Correct
RCTA (Rear Cross Traffic Alert) is designed to assist drivers when reversing out of parking spaces or driveways. It uses sensors at the rear of the vehicle to monitor cross traffic coming from the sides.
Here’s how it operates:
Activation: RCTA activates when the vehicle is put in reverse and continuously scans the area behind the car for cross-traffic.
Detection and Warning: If a vehicle, cyclist, or pedestrian is detected approaching from the side, it issues a warning (audible, visual, or both) to alert the driver, giving them time to adjust their manoeuvre.
When it detects a vehicle approaching from the cross direction at the next intersection and there is a danger of collision: This is incorrect because it describes a forward-facing system, not RCTA, which is only active when reversing.
When overtaking, it detects that a vehicle is approaching from the opposite direction: This is incorrect because overtaking assistance is handled by systems like forward collision warning, not RCTA.

Video Explanation

Explanation:

At a speed less than 15 km/h: Correct
The Rear Cross Traffic Alert (RCTA) system is designed to assist drivers when reversing by detecting cross traffic approaching from the sides. In some vehicles, RCTA is integrated with an automatic braking feature that intervenes if a potential collision is detected and the driver does not respond to warnings. This braking intervention is typically active at low reversing speeds, such as below 15 km/h (9 mph) in Volvo vehicles.
At a speed less than 30 km/h: Reversing at speeds approaching 30 km/h is uncommon and unsafe. RCTA with braking intervention is calibrated for lower speeds to match typical reversing behavior.
At a speed less than 50 km/h: Reversing at such high speeds is highly unusual and dangerous. RCTA systems are not designed for these speeds. The braking intervention feature of RCTA operates below 15 km/h, ensuring safe reversing practices.

Video Explanation

Explanation:

Have better view of the rear: Correct
The primary purpose of a reversing camera is to improve the driver’s visibility of the area directly behind the vehicle, enhancing safety by helping the driver avoid obstacles, pedestrians, or other hazards.
Carry out the parking manoeuvre quickly and safely: While it helps with parking, the camera’s focus is on safety and precision, not speed.
Being able to circulate more than 15 meters to make a parking lot: This is irrelevant to a reversing camera, which is designed only for assisting with reversing, not for covering distances or navigating parking lots.

Video Expanation

Explanation:

Of the cameras installed on the periphery of the vehicle: Correct
The 360-degree camera system in vehicles simulates an overhead (bird’s-eye) view of the car using images captured from multiple cameras installed around the vehicle. These cameras are strategically positioned to provide a full view of the surroundings. Here’s how it works:
Camera Placement:
Front camera: Mounted near the grille or logo.
Rear camera: Integrated into the trunk or tailgate.
Side cameras: Installed on the underside of the side mirrors.
Image Stitching: The images captured by these cameras are processed and digitally “stitched” together by the vehicle’s system to create a single, seamless overhead view. This simulation makes it easier for the driver to see obstacles around the vehicle, especially in tight spaces.
From a satellite: The images do not come from satellites. Satellites provide large-scale geographic views, not real-time, vehicle-specific perspectives.
There is no system that simulates a zenithal plane of the vehicle: This is incorrect because 360-degree camera systems, also known as Surround View or Bird’s-Eye View systems, are widely available in modern vehicles and are specifically designed to simulate a top-down view.

Video Explanation

Explanation:

Avoid a possible accident due to fatigue or sleep: Correct
The ADAS Fatigue Detection System is designed to monitor the driver’s behavior and identify signs of drowsiness or fatigue. Its primary purpose is to prevent accidents caused by a lack of attention, fatigue, or sleepiness by alerting the driver to take action.
Monitoring Driver Behavior: The system uses sensors and cameras to track the driver’s actions, such as steering patterns, lane-keeping consistency, and reaction times. Some systems also monitor facial features like blinking frequency, head position, or eye movements.
Issuing Warnings: When the system detects signs of fatigue or drowsiness, it issues warnings through sounds, vibrations, or visual alerts on the dashboard. This is meant to prompt the driver to take a break or rest.
Take control of the direction of the vehicle in case of drowsiness of the driver: Fatigue detection systems are not designed to control the vehicle’s direction. Steering or directional control falls under systems like Lane Keeping Assist or Emergency Steering Assist.
Carry out an emergency stop when it detects that the driver is not in optimal conditions to continue driving: Fatigue detection systems do not perform emergency stops. Their function is limited to monitoring and alerting the driver.

Video Explanation

Explanation:

The advance driver distraction warning system or ADR: Correct
The Advanced Driver Distraction Warning (ADR) system is designed to detect deviations in the driver’s gaze or head position that indicate inattentiveness or drowsiness. It uses sensors or cameras to monitor the driver’s eyes, head position, and facial expressions. If it detects signs of distraction, such as the driver looking away from the road for too long, it will issue a warning, often through an alert sound or visual signal on the dashboard. This system enhances safety by prompting the driver to focus on the road and avoid accidents due to inattention.
The LTS or Lane Tracing System: This system detects lane markings and helps keep the vehicle centered within its lane. It assists in lane-keeping but does not monitor the driver’s gaze or head position.
The Head-up Display (HUD): The HUD projects important driving information onto the windshield for easy viewing without taking the eyes off the road.

Video Explanation

Explanation:

You are performing an emergency stop: Correct
The Electronic Brake-force Distribution (EBD) system is part of the Advanced Driver Assistance Systems (ADAS). Its main function is to optimize braking by adjusting the distribution of braking force between the front and rear wheels, based on load and road conditions. EBD works with systems like Automatic Emergency Braking (AEB) or Brake Assist (BA) during emergency stops.
EBD ensures effective braking force distribution during heavy or sudden braking.
It helps maintain stability and reduces stopping distance in emergency situations.
It adapts the braking force to avoid skidding or losing control.
You are about to make a change of direction at the next intersection: EBD does not monitor direction changes; systems like Lane Keeping Assist (LKA) are designed for that.
Driving at a speed lower than the minimum speed established on the road: EBD is unrelated to vehicle speed monitoring. Systems like Adaptive Cruise Control (ACC) handle speed-related functions.

In a rapid flash of stop lights when the brakes are applied hard: Correct
The Emergency Braking Warning (EBW) system is a feature of Advanced Driver Assistance Systems (ADAS) designed to alert other drivers when a vehicle performs a sudden or hard braking manoeuvre. This warning typically comes in the form of rapid flashing of the stop lights to reduce the risk of rear-end collisions.
Functionality of EBW: When the driver applies the brakes abruptly, EBW activates the rear brake lights to flash rapidly, signaling to vehicles behind that the car is decelerating quickly, giving them time to react and avoid a collision.
Safety Enhancement: This visual cue is more effective than a constant brake light in high-stress or emergency situations.
The system emits a sound that tells the driver to brake to avoid a collision: This describes systems like Forward Collision Warning (FCW), not EBW.
The brake pedal shakes when you press it hard: This is a characteristic of Anti-lock Braking Systems (ABS), unrelated to EBW.

When the vehicle involuntarily leaves the lane in which it is traveling: Correct
The Lane Departure Warning (LDW) system is designed to enhance safety by warning drivers when their vehicle unintentionally drifts out of its lane. This typically happens when the driver is distracted, drowsy, or not paying full attention. The system uses cameras or sensors to monitor the vehicle’s position within the lane and provides alerts (such as vibrations or audio signals) if the vehicle crosses lane markings without signaling.
In a lateral displacement indicated by the blinker: While this option seems related, it is too vague and does not capture the specific function of the Lane Departure Warning (LDW) system. The phrase “involuntary change of direction” does not specify the context of a lane departure, making it unclear.
In an involuntary change of direction: While this option seems close, it is not specific enough. LDW specifically monitors lane departures rather than general directional changes. A change in direction can occur without leaving the lane, which the system does not monitor or warn against.

With the “Lane Departure Warning System” that will act in advance: Correct
The Advanced Lane Keeping System (LKA) is designed to assist drivers in maintaining their vehicle’s position within the lane. It actively intervenes to correct the steering when it detects that the vehicle is drifting out of its lane without the use of turn signals. The Lane Departure Warning System (LDW) complements LKA by providing alerts to the driver when the vehicle begins to drift out of its lane.
With the “Advanced Driver Distraction Warning System” that will act later: This system monitors the driver’s attention levels but does not directly relate to lane-keeping.
With the “Fatigue or Drowsiness Detection System” that will act previously: The fatigue detection system identifies signs of tiredness or drowsiness in the driver. However, it does not specifically assist in lane-keeping or provide warnings for lane departures.

It remains deactivated: Correct
The Lane Keeping Assistance (LKA) system is designed to assist drivers in maintaining their position within the lane. However, when the driver actively performs a manoeuvre with the clear intention of leaving the lane (e.g., using the turn signal or making a deliberate steering input), the system recognizes this and deactivates itself. This ensures that the system does not interfere with the driver’s intentional actions.
Calculate the most favorable trajectory of the vehicle and correct the driver’s manoeuvre: This is incorrect because LKA does not override intentional driver actions. Its purpose is to assist, not to take complete control of the vehicle.
It maintains the vehicle’s position in the lane and prompts the driver to manually deactivate the system: This is also incorrect because LKA does not force the driver to manually deactivate it during an intentional manoeuvre. It is designed to deactivate itself when the driver shows clear intent to leave the lane, ensuring smooth operation without unnecessary alerts or interventions.

This system only emits optical, acoustic, or tactile warning for the driver: Correct
The Blind Spot Monitoring Information System (BSIS-BSM) is a safety feature that warns the driver when another vehicle is in their blind spot, typically using visual (optical), audio (acoustic), or tactile (vibration) alerts. This system is meant to assist the driver by providing warnings but does not intervene in the driving systems like steering or braking.
Yes, coming to act on the direction or even stop the vehicle in case of risk of run over or collision: This is incorrect because BSMS-BSM only provides warnings; it does not intervene by controlling the vehicle’s direction or stopping it.
No system can intervene in the driving systems of the vehicle: This is also incorrect because many ADAS systems, such as automatic emergency braking or lane-keeping assist, do intervene in the driving systems to prevent collisions or maintain lane discipline. Therefore, the statement is inaccurate.

A camera or sensor placed at the rear of the interior mirror: Correct
The vehicle’s traffic sign recognition system typically uses a camera or sensors mounted at the rear of the interior mirror to detect and read vertical traffic signs. These cameras are designed to capture images of road signs, such as speed limits, no entry, and other regulatory signs, which are then processed by the system to alert the driver or display the sign’s information on the dashboard or head-up display.
Always use navigation data to display signal information: This is incorrect because the system primarily uses cameras or sensors to detect traffic signs, not just navigation data.
This system only shows information about road markings: This is also incorrect because the system is designed to recognize traffic signs, not just road markings. Road markings may assist in navigation, but the recognition system focuses on signs like speed limits, stop signs, etc.

Tire pressure or its variation over time: Correct
The TPM (Tire Pressure Monitoring) system is designed to monitor and detect changes in tire pressure. It alerts the driver when there is a significant variation in the pressure of one or more tires, which could affect the vehicle’s safety, fuel efficiency, and handling. This system tracks tire pressure over time and helps prevent potential issues such as tire blowouts or poor performance due to under-inflation.
The blind spots of the vehicle: This refers to the Blind Spot Monitoring (BSM) system, not TPM. BSM uses sensors or cameras to monitor areas beside and behind the vehicle where the driver may not have a clear view.
That the vehicle does not move when the vehicle remains parked on a slope: This function is related to a Hill Start Assist or Auto Hold system, not TPM. Hill Start Assist prevents the vehicle from rolling backward when starting from a stop on an incline.

Explanation:

The Intelligent Speed Assistant (ISA) is an Advanced Driver Assistance System (ADAS) designed to help drivers comply with speed limits and improve road safety.

• ISA does not automatically force the vehicle to a new speed limit but assists the driver in maintaining a specified speed.
• It detects speed limit signs using cameras and GPS data and alerts the driver if they are exceeding the speed limit.
• Some versions of ISA allow the vehicle to adjust its speed automatically, but the driver can always override it.

Why not the other options?

• B) Increase the speed of the vehicle when it detects that the driver is going very slowly. ❌

  • ISA does not work to increase speed if a driver is going slowly. It is designed to help drivers avoid exceeding speed limits, not to force them to drive faster.

• C) Detect speed limit signs and set the speed of the vehicle to that indicated on the sign, in any case. ❌

  • ISA does detect speed limit signs, but it does not automatically force the vehicle to follow the limit in all cases. The driver remains in control and can override the system if needed.

ISA is a safety feature aimed at reducing speeding-related accidents, ensuring drivers stay within legal speed limits while still allowing manual control. 🚗

It controls the flow of fuel that is fed to the engine: Correct
The “Speed Limitation Devices” (SLI) are designed to limit the maximum speed of a vehicle. When the vehicle exceeds the speed set by the driver, the system intervenes by reducing the power sent to the engine. This is typically done by controlling the fuel flow to the engine, which slows down the vehicle and prevents it from going faster than the specified speed.
Stop the vehicle to avoid a possible accident: This is incorrect because SLI systems do not completely stop the vehicle. They only limit the speed by restricting engine power, but they do not bring the vehicle to a complete stop.
It only works when the vehicle is traveling below the perceived speed: This is incorrect because the SLI system is designed to activate when the vehicle exceeds the specified speed, not when it is below it.

Yes, as long as it is a driver warning system that does not act on the vehicle’s driving systems: Correct
While it is possible to install advanced driving assistance systems (ADAS) on an already registered car, the key factor is that the system must not interfere with the vehicle’s primary driving systems (like steering, braking, or acceleration). Many aftermarket ADAS solutions are available that offer features like lane departure warning, forward collision warning, or blind spot monitoring, but these typically only provide alerts to the driver. They do not actively intervene in the vehicle’s driving systems, which makes them easier to install on vehicles that were not originally equipped with such systems.
Yes, any of them in order to improve the active safety of the vehicle and avoid accidents: This is not correct, as some ADAS systems, especially those that control steering or braking, may require significant modifications to the vehicle and are not always compatible with existing systems. Installing such systems could also affect the vehicle’s warranty or legality in certain regions.
No, in no case: This is incorrect because, as mentioned, it is possible to install certain driver assistance systems through aftermarket solutions, as long as they do not interfere with the vehicle’s driving systems.

Avoid collisions with pedestrians or vehicles: Correct
The Blind Spot Monitoring Information System (BSIS-BSM) is designed to detect objects, vehicles, or pedestrians that may be in the driver’s blind spots, particularly when changing lanes or merging. It alerts the driver to the presence of vehicles or obstacles in areas that are difficult to see, helping to avoid potential collisions.
Prevent the vehicle from rolling backwards when leaving on a hill: This is the function of Hill Start Assist, not BSIS-BSM.
Prevent occupants from getting out of the vehicle and walking on the road in an emergency: This is not a function of BSIS-BSM. It would be related to other safety systems like emergency stop systems or safety alerts for passengers.

Reducing the intensity of light that falls directly on the target allowing the driver to enjoy maximum visibility of the rest of the road: Correct
Vehicles with state-of-the-art LED automatic lights are often equipped with adaptive lighting systems that adjust the intensity and direction of the headlights to avoid blinding or dazzling other road users. By reducing the intensity of the light that directly hits other vehicles or pedestrians, the system ensures that the driver gets optimal visibility without causing discomfort or danger to others on the road.
Diverting the lights to the right while there are other road users who may be dazzled: This is not a comprehensive solution. While it’s true that some lighting systems can adjust the direction of the headlights to avoid blinding oncoming drivers, simply diverting the lights to the right doesn’t ensure optimal visibility for the driver or properly protect other road users.
Reducing the speed of the vehicle, even stopping it: This is not a typical function of LED automatic lights. Reducing speed or stopping the vehicle is a response to specific road conditions or hazards, but it’s not related to how the vehicle’s headlights function to avoid dazzling other drivers.
