Explanation
To share the road safely, always maintain at least a two-second following distance from the vehicle in front of you. This rule applies at any speed under normal driving conditions on state roads and U.S. highways. However, you should increase your following distance to at least four seconds in poor weather, low-light conditions, or when driving larger vehicles that take longer to stop. Leaving extra space gives you more time to react and helps prevent rear-end collisions.
