What is the safe distance a driver should maintain when following another vehicle?

Maintaining a safe following distance is crucial for ensuring safety on the road, particularly when driving at higher speeds. The correct approach is to keep at least one car length for every 10 mph of speed. This allows for adequate reaction time in the event of sudden stops from the vehicle in front. For example, if you are traveling at 60 mph, maintaining a distance of at least six car lengths gives you enough space to react if the leading vehicle suddenly brakes.

This method helps drivers anticipate the actions of the vehicle ahead, reduces the likelihood of rear-end collisions, and allows more room for safe maneuvering. It reflects a defensive driving technique that prioritizes safety, accommodating braking times and road conditions.

The other options suggest distances that are either too close or impractical for safe driving. Following too closely can significantly increase the risk of accidents, particularly if the vehicle ahead makes an unexpected stop. Therefore, adhering to the guideline of one car length per 10 mph ensures a safer driving environment for everyone on the road.
