Nova Scotia Driving Test Practice: Ace your driving test

Why is it dangerous to drive too closely behind another vehicle?

1. It reduces your reaction time in case the vehicle in front stops suddenly

2. It increases your vehicle's fuel efficiency

3. You have a better view of the road ahead

4. It allows you to pass the vehicle more quickly

The correct answer is: It reduces your reaction time in case the vehicle in front stops suddenly

Driving too closely behind another vehicle, commonly referred to as tailgating, significantly reduces your reaction time if that vehicle has to stop suddenly. When there is not enough space between your vehicle and the one in front, you have less time to assess the situation and respond appropriately. This limited space means that in the event of an emergency, such as the vehicle ahead braking unexpectedly, you may not have sufficient distance to stop safely, which can lead to a collision. Maintaining a safe following distance allows for adequate reaction time to various road conditions and unexpected actions of other drivers. It’s crucial for preventing accidents and ensuring the safety of all road users. In contrast, options that suggest fuel efficiency, better visibility, or quicker passing do not address the critical safety aspect that comes with maintaining an appropriate space between vehicles. Therefore, understanding the importance of safe distances can help drivers make better decisions on the road.
