Signal a turn at least _________ before you make the turn.

Explanation

Before you turn, signal at least 100 feet in advance to let other drivers know that you plan to turn. (Note that at 40 mph, a vehicle will travel 100 feet in less than two seconds.) If there are other streets, driveways, or entrances between you and where you want to turn, wait until you have passed them before you signal. If you signal before you pass those places, you may mislead other drivers into thinking that you plan to turn there.
