How much space should you leave between your vehicle and the one ahead for every 10 feet of your vehicle's length under good driving conditions?

One second
Two seconds
Three seconds
Four seconds

The correct answer is: One second

Leaving one second of space for every 10 feet of your vehicle's length under good driving conditions is important for maintaining a safe following distance. This rule provides drivers with a guideline to recognize how much time they should allow themselves to react to sudden changes in traffic. Since longer vehicles require more time to stop or maneuver, the concept is designed to ensure that drivers have adequate time to react without being too close to the vehicle ahead. By adhering to this guideline, drivers can enhance their visibility and reaction time, thus reducing the risk of accidents that can occur from tailgating or being too close to the vehicle in front. Therefore, one second for every 10 feet of vehicle length is a sensible and practical approach to ensuring safety while driving.
