At highway speed, the distance you should look ahead is about how many miles?

• A. 1 mile
• B. 1/4 mile
• C. 1/2 mile
• D. 3/4 mile

Answer: (B)

When you’re driving at highway speeds, you need a horizon that gives you time to notice problems and plan your actions. About 15 seconds of travel time, which is roughly a quarter of a mile, is the practical look-ahead distance. That distance lets you spot brake lights, slowdowns, merging traffic, or obstacles early enough to gradually slow, steer, or change lanes safely. If you look farther than that, you’ll be focusing on things too distant to act on in the moment; if you look shorter, you won’t have enough time to react. So, aim to scan about a quarter mile ahead and keep your eyes moving to anticipate changes in traffic conditions.
