Question

Similar to the sight distance rule, the following distance rule states that at 30 mph, a following time of __ to __ seconds should be adequate to stop if the following vehicle. However, at higher speeds, the best rule to use is the __-second rule.

Answer 1

The following distance rule and the 3-second rule help determine the safe stopping distance between vehicles at different speeds.

Step-by-step explanation:

The following distance rule states that at 30 mph, a following time of 2 to 3 seconds should be adequate to stop if the following vehicle. However, at higher speeds, the best rule to use is the 3-second rule.

This means that at 30 mph, you should keep a distance of 2 to 3 seconds between your vehicle and the one in front of you. This allows you enough time to react and stop safely. At higher speeds, such as on highways, it's recommended to maintain a distance of at least 3 seconds to ensure enough stopping distance. The higher the speed, the longer it takes for a vehicle to stop.
