At highway speed, how far ahead should you look to identify hazards?

• A. 1/4 of a mile at highway speed
• B. 1/2 mile
• C. 1 mile
• D. 100 feet

Answer: (A)

When you’re moving fast on the highway, you must scan far enough ahead to spot hazards in time to react and deal with them safely. A quarter of a mile ahead is the guideline most often taught because it gives you a window to notice problems and take action. At typical highway speeds, that distance means roughly 15 seconds of travel time, which is enough to see slow or stopped traffic, debris, merging vehicles, or construction, and then brake, steer, or change lanes as needed. Looking only 100 feet ahead leaves you with only a few seconds to respond, which isn’t enough at highway speed. Scanning farther than a quarter mile—like half a mile or a mile—offers more time, but isn’t necessary for normal highway driving and can distract you from maintaining speed and control.
