The statement 'The rule used to estimate stopping distance under ideal conditions is the 4-second rule' is:

• A. True
• B. False
• C. It uses a 2-second rule.
• D. It uses a 5-second rule.

Answer: (A)

Maintaining a safe following distance is about ensuring you have enough time to react and stop. In ideal driving conditions, the four-second rule is used to estimate that stopping distance. Pick a fixed object ahead and count seconds as you pass it; if you still see it four seconds later, you’re at a safe cushion. If you reach it sooner, you’re too close and should back off to create more room. This rule combines your reaction time with braking distance, giving a practical guideline for safe stopping under good conditions. Remember, when conditions aren’t ideal—wet, snowy, or poor visibility—you should increase that spacing beyond four seconds.
