What is the term for the distance measured in seconds that a driver's eyes look ahead of their vehicle?

• A. Eye-Lead time
• B. Following distance
• C. Reaction time
• D. Stopping distance

Answer: (A)

Eye-lead time is the amount of time, in seconds, that a driver's eyes are looking ahead of the vehicle to anticipate hazards before they become emergencies. This forward scan gives you a mental cushion to react—brake, steer, or adjust speed—before you actually need to respond. It’s about planning rather than the physical distance you are from another car or how long your brakes take to work. A typical target is about 2 to 3 seconds of eye-lead time at normal speeds, and you should increase it in rain, snow, or at higher speeds. This rate of looking ahead is different from following distance (the space to the vehicle in front), from reaction time (the delay between noticing a hazard and starting to act), and from stopping distance (the total distance to come to a stop after you begin braking).
