What is the recommended approach to following distance under normal conditions?

• A. Use a braking distance or time-based rule appropriate for speed and conditions; increase distance in poor weather or low visibility
• B. Maintain a fixed 1-second following distance
• C. Tailgate to keep traffic moving
• D. Follow at the same distance regardless of speed

Answer: (A)

The key idea is to choose a following distance that scales with how fast you’re going and the current road conditions, using a braking-distance or time-based rule that fits the speed. This approach ensures you have enough space to react and stop if the vehicle ahead slows or stops. You should increase that distance in poor weather or low visibility because stopping distances grow and reaction times can be longer. Fixed short gaps don’t adjust for speed, tailgating reduces your margin, and following at the same distance regardless of speed ignores how braking distance increases with velocity.
