What is the term Eye-Lead time best described as?

• A. The distance in feet you look ahead
• B. The distance in seconds you look ahead
• C. The reaction time to hazards
• D. The braking distance required at speed

Answer: (B)

Eye-lead time is the amount of time you look ahead to scan for hazards, expressed in seconds. This forward-looking time lets you perceive, decide, and prepare a response before a hazard becomes urgent, tying your speed to how far ahead you monitor. It’s helpful to think of it as how many seconds you’re watching ahead, not a fixed distance in feet. For example, at 60 mph a two-second eye-lead time means you’re watching roughly 176 feet ahead; increasing that time gives you more room to react safely. This concept isn’t the same as the pure reaction time to hazards or the braking distance required at speed, and it isn’t simply a feet-based measure of how far you look.
