What is the recommended following distance from another vehicle when driving at a speed of 60 mph?

Answer: B — Two seconds

The recommended following distance when driving at a speed of 60 mph is two seconds. This guideline is based on the principle that a driver needs sufficient time to react to an unexpected situation. At 60 mph, a vehicle travels approximately 88 feet per second. By maintaining a two-second following distance, a driver ensures they have enough space to react and safely stop if the vehicle in front suddenly brakes. This two-second rule allows for proper distance to account for reaction time and potential stopping distances, which increase with speed. It also provides a buffer zone that enhances safety, as it reduces the likelihood of a rear-end collision. Understanding this concept is crucial for drivers, as it helps promote safe driving practices and encourages drivers to maintain awareness of their surroundings and the traffic flow.
