At highway speed, which distance is the recommended look-ahead distance?

• A. 1/8 mile
• B. 1/4 mile
• C. 1/2 mile
• D. 1 mile

Answer: (B)

At highway speeds you need to scan far enough ahead to spot hazards and plan your actions in advance. The recommended look-ahead distance is roughly a quarter of a mile. This distance gives you enough time—about 15 seconds at typical highway speeds—to observe traffic, anticipate changes, and slow down or change lanes smoothly rather than reacting at the last moment. A shorter look-ahead (like an eighth of a mile) leaves almost no time to respond to sudden events, while a much longer look-ahead (half a mile or more) isn’t practical in normal traffic and can still miss closer developments.
