Whenever you begin a new medical treatment for some ailment and you plan to drive, it is advisable to know the side effects your medications can have on your body and to be more cautious while driving, especially during the first days of treatment, using the lowest effective dose so that the medications don’t reduce your ability to drive.

The obligation sign R-405 shown in the image indicates that, on the roadway where the sign is located, it is obligatory for only motorcycles without sidecar to travel, and no other type of vehicle may travel here.

The yellow road markings that you may find on the road such as those in the image correspond to construction zones, and their duration is limited to the duration of the construction that they signal. The road markings will be removed once the work is finished, and the usual signage will resume.

Drivers who habitually or occasionally take medications that affect the nervous system should be very familiar with the symptoms that their illness may cause when driving, and they should always consult their doctor before getting behind the wheel and follow the doctor’s instructions to minimize the risk of an accident.

Novice drivers, during the first two years after getting their driver’s license, are forbidden from driving with an alcohol level greater than 0.3 grams per litre of blood or 0.15 milligrams per litre of exhaled air.

The vertical general indication sign S-53 shown in the image indicates that a section of road with a single lane in one direction will change to two lanes in the same direction.

The vertical hazard warning sign P-29 warns road users that, where the sign is located, there is an area nearby with a hazard due to frequent strong crosswinds.

Vertical prohibition sign R-302 that we see in the image indicates that in the place where it is located the right turn is prohibited for all types of vehicles.

The sign R-308A shown in the image prohibits parking of vehicles on the side of the road where the sign is located on the odd days of each month. Unless indicated otherwise, the prohibition begins at the sign and ends at the next intersection. It does not prohibit stopping.

Among the possible adverse effects that depression can cause on driving are difficulty maintaining concentration, an increase in insecurity when making decisions at the wheel, an increase in sensitivity to drowsiness and fatigue, and making decisions more slowly and less correctly.

Vertical entry prohibition sign R-114 shown in the image, prohibits the entry of cycles to the road where the sign is located.

It shall not prohibit the entry of other vehicles with or without engine.

The vertical restriction or prohibition sign R-307 shown in the image prohibits all road users from stopping and parking on the side of the road where the sign is placed. Unless indicated otherwise, the restriction begins at the sign and ends at the next intersection.

Traffic officers can proceed to immobilize your vehicle when the vehicle exceeds the legally permitted emission of gases, fumes and noise for each type of vehicle. They may also immobilize it for other reasons, for example, when there are too many occupants in the vehicle or when they suspect that the vehicle’s controls may have been tampered with.

The vertical hazard warning sign P-17 shown in the image indicates that we are approaching a stretch of road where there is going to be a narrowing of the roadway that may be dangerous for traffic.

The road marking on the image, indicates that we are approaching a level crossing with or without barriers ahead. The letters P and N proceed from the word “Paso a Nivel” (Level crossing in Spanish).

All drivers of motor and non-motor vehicles traveling on public roads are obligated to undergo any alcohol tests required by traffic officers. In the case of a positive test result, the officer can proceed with the immediate immobilization of the vehicle via a seal or other procedure that impedes its normal operation, unless it can be driven by another capable person.

The vertical sign S-61a indicating left fork on a three-lane road indicates that on those roads with three lanes of traffic in the same direction, on the next stretch of road the left lane will turn to the same side.

Driving for long periods of time, not stopping to rest or doing it in an insufficient or inadequate way, are the main causes of fatigue at the wheel.

Rushing to get somewhere or maintaining an excessive speed for a long time requires you to concentrate more on driving and can alter your psychophysical state.

When you obtain a new driving license (Class B) after holding a Class A license for a year, the probationary period for alcohol limits applies separately to each license category. Since Class B is a new license, the reduced alcohol limit (0.3 g/L) will apply again for one year.

Alcohol consumption slows down the driver’s reaction time, meaning they take longer to respond to hazards, signals, or sudden changes in traffic. It also impairs coordination, judgment, and concentration, increasing the risk of accidents.

In the standard configuration of motorcycle controls, the throttle is located on the right handlebar grip and is controlled by twisting it with the right hand. This allows the rider to accelerate smoothly while maintaining control of the handlebars.

If the foot brake fails while driving at high speed (100 km/h), the safest way to stop the vehicle is by gradually downshifting to lower gears. This technique, called engine braking, slows down the vehicle without relying on the foot brake. Once the speed is significantly reduced, the handbrake can be used carefully to bring the vehicle to a complete stop.

When a vehicle skids, the first step is to stop braking immediately to regain control. Braking while skidding can worsen the situation by locking the wheels, making it harder to steer. By releasing the brakes, maintaining a firm grip on the steering wheel, and steering smoothly, the driver can recover control and bring the vehicle back on track.

Exterior rearview mirrors cannot be replaced with a panoramic interior mirror because external mirrors are essential for visibility, especially for monitoring blind spots and surrounding traffic. Interior mirrors, even panoramic ones, do not provide the same field of vision as exterior mirrors, particularly for lane changes, overtaking, and reversing. Traffic laws generally require vehicles to have functional exterior mirrors to ensure safe driving.

Most accidents occur in the afternoon, at the end of the working day. This is because:

Increased Traffic – Many people are commuting home from work, leading to congested roads.
Driver Fatigue – After a long day of work, drivers are more likely to be tired, reducing their reaction time.
Distractions – Drivers may be in a hurry, using their phones, or thinking about personal matters rather than focusing on the road.
Changing Light Conditions – As the sun sets, visibility decreases, increasing the chances of accidents.

In road safety, vulnerable groups refer to those who are at a higher risk of injury or fatality in traffic-related incidents due to their lack of protection compared to vehicle occupants.

These groups include:
Pedestrians (especially children, the elderly, and people with disabilities).
Cyclists.
Motorcyclists.
Users of personal mobility devices (e.g., electric scooters).

Using the air inlets on the dashboard (also known as the recirculation mode) is the most fuel-efficient option because it uses the air inside the car, reducing the need for the air conditioning system to work harder to cool the incoming outside air. This minimizes the energy required to cool the car, saving fuel.

Airbags are designed to inflate in the event of a crash to protect the occupants. If a seat belt is not worn, the occupant might not be in the proper position during a collision, meaning the airbag could deploy at the wrong angle or with too much force, which may lead to injury or reduced effectiveness.

Headrests are meant to prevent whiplash injuries in rear-end collisions by supporting the head and neck. If the seat belt is not worn, the person may be thrown too far back in their seat, and the headrest may not provide adequate protection.
