How much distance should you give the vehicle in front of you?

Enough room to decelerate if needed
One car length per 10 mph of speed
As little as possible
Enough space to pass

The correct answer is: Enough room to decelerate if needed

Having enough room to decelerate is crucial for maintaining a safe following distance. Option B, while a common rule of thumb, is not always accurate as it only applies to certain speeds and may not be enough in case of emergencies. Option C is incorrect as tailgating can lead to accidents and does not allow for a safe stopping distance. Option D is incorrect as maintaining a safe following distance is not just about passing other vehicles, but also allowing for safe braking and avoiding potential collisions. Therefore, option A is the best answer as it emphasizes the importance of having enough distance to safely slow down or stop if needed.
