The speed adapts to the conditions of the driver, vehicle, and environment: Correct
Driving at a suitable speed means adjusting your speed based on various factors such as the road conditions, weather, traffic, and the driver’s abilities. For example, in rain, fog, or heavy traffic, it may be necessary to drive slower than the posted speed limit to ensure safety. Similarly, if the road is clear and the vehicle is in good condition, the driver can drive at a higher speed within legal limits. This approach helps maintain control of the vehicle and reduces the risk of accidents.
Maximum speed limits are respected: While respecting speed limits is important, the appropriate speed goes beyond just following the maximum limit. It must also consider road conditions, traffic, and visibility.
Driving very slowly: Driving excessively slowly can be dangerous too, as it might disrupt the flow of traffic or cause accidents, especially on faster roads.
