How far should a driver look ahead of the vehicle while driving?

Question

Accepted Answer

C: 12-15 seconds.. Good drivers look ahead for at least 12 to 15 seconds. That means looking at a travel time of 12 to 15 seconds forward. This is equivalent to one block at slower speeds; at highway speeds, that's equivalent to a quarter of a mile. If you do not follow the 12 to 15-second rule, you may have to resort to panic-breaking if you need to stop or make quick lane changes.
