Under normal conditions, the safe following distance behind the vehicle ahead is expressed in seconds as?

• A. One second
• B. Three seconds
• C. Four seconds
• D. Two seconds

Answer: (D)

The idea is a time-based rule for keeping enough space to react and stop safely. Under normal conditions, leaving about two seconds of space behind the vehicle in front gives you time to notice a problem, respond, and brake without colliding. A practical way to apply this is to pick a stationary object on the road ahead. As the vehicle in front passes that object, start counting seconds. If you reach the object after about two seconds, you’re at a safe following distance. If you can’t count two seconds before the object passes, slow down a bit to increase the gap. Keep in mind that this two-second rule is for normal, dry conditions. In rain, snow, ice, fog, or if you’re following a large vehicle, increase the gap to three or even four seconds to compensate for longer stopping distances and reduced visibility.
