Nova Scotia Driving Test Practice: Ace your driving test

How can a driver maintain a safe following distance?

1. Use the "one-second rule"

2. Use the "two-second rule"

3. Use the "three-second rule"

4. Follow the vehicle closely

The correct answer is: Use the "three-second rule"

Maintaining a safe following distance is crucial for ensuring the safety of everyone on the road, including the driver and other road users. The three-second rule is a method that allows a driver to assess and maintain an appropriate distance from the vehicle ahead. This rule suggests that the driver should pick a fixed point on the road, such as a sign or a tree, and when the vehicle in front passes that point, the driver should be able to count to three before reaching the same point. Using the three-second interval helps account for various driving conditions, giving the driver ample time to react in case the vehicle in front suddenly stops or slows down. This longer following distance provides a buffer that accommodates for poor weather conditions, road surface issues, or any other unexpected circumstances that might require a longer reaction time. In contrast, shorter rules like the one-second or two-second rule may not provide sufficient distance in many driving situations, particularly at higher speeds or in adverse weather conditions. Following closely to another vehicle significantly increases the risk of collisions, as it reduces the driver's reaction time and limits their ability to respond safely to sudden changes. Therefore, adopting the three-second rule is the most effective method for maintaining a safe following distance.
