Arizona Drivers Permit Pactice Exam

What distance should you maintain from the vehicle ahead of you in normal driving conditions?

1. 10 feet

2. 20 feet

3. 3 seconds

4. 5 car lengths

The correct answer is: 3 seconds

Maintaining a distance of 3 seconds from the vehicle ahead in normal driving conditions is crucial for ensuring safety on the road. This concept, often referred to as the "three-second rule," helps drivers establish a safe following distance that accounts for both their speed and the potential reaction time needed if the vehicle in front suddenly stops or slows down. To apply this rule, a driver should watch for a fixed object on the side of the road and start counting seconds as the vehicle ahead passes that object. If the driver reaches the object before counting to three, they are following too closely and should increase their distance. This practice allows for adequate stopping space under normal conditions, reduces the likelihood of rear-end collisions, and provides enough time to react to sudden changes in traffic. Other options, like maintaining a set number of feet or car lengths, can vary significantly depending on vehicle speed and size. In contrast, the three-second rule provides a flexible and practical guideline that adjusts for different scenarios while prioritizing safety.
