A. 3 seconds

B. 4 seconds

C. 3 car lengths

D. 4 car lengths

Answer: B. 4 Seconds

Explanation: You should maintain a four-second following distance at all times. That means, once the vehicle ahead of you passes a fixed object, it should take you at least 4 seconds to arrive there at your current speed.

A. 3 seconds

Explanation:

The general rule is called "Two-second rule", but in some areas "three-second rule" is recommended because of the safety.

This means the driver of the vehicle behind the other would need at least three seconds at the same speed to reach the one that is ahead.

It is applied mostly for cars but is also used for all kinds of vehicles. The rule serves the purpose of safety so that the driver in the vehicle behind can stop safely in the case of possible danger.
