When driving with good visibility, good traction and have a safe alternate path of travel, you should maintain a minimum:

• A. 3 seconds
• B. 1 second
• C. 5 seconds
• D. 2 seconds

Answer: (C)

The main idea here is how much space you should leave behind the vehicle in front of you, measured as a time interval. Using a time-based rule helps account for your reaction time plus the braking distance needed to stop safely. Even when visibility and road grip are good, you want enough cushion to notice a hazard, react, and slow down without rushing or swerving. Having a safe alternate path of travel adds an extra layer of safety, so you’re not stuck trying to stop in a tight squeeze if something goes wrong. The five-second gap gives you a comfortable margin to react and either brake smoothly or steer to the open path if needed. Shorter gaps—like one, two, or even three seconds—leave less room for error and can lead to a collision if the front vehicle brakes suddenly or a new hazard appears.
