Question

It is best to use which of the following distance rules on dry roads?

1) 2-second rule
2) 3-second rule
3) 4-second rule
4) 5-second rule

Answer 1

The recommended distance rule on dry roads is the 3-second rule, which allows for a safe reaction and stopping distance to avoid collisions.

Step-by-step explanation:

On dry roads, it is recommended to use the 3-second rule for maintaining a safe following distance from the car in front of you. This rule suggests that when the rear of the vehicle ahead of you passes a fixed point, such as a pole or a tree, at least three seconds should elapse before your vehicle passes the same point. This allows for an adequate distance to react and stop your car if necessary to avoid a collision.

Bridget's observation of cars travelling from one pole to the other within 3 seconds indicates their speed when covering the 50 m stretch. This real-world example aligns with the principles behind the 3-second rule, showing the importance of distance for safe stopping on dry pavement.
