When you plan to make a turn, you must signal at least _________ ahead of the turn.

Explanation

Whenever you intend to turn, communicate your intention well in advance. Under Virginia law, if you intend to turn and you're traveling above 30 mph, you must signal continuously for at least 100 feet before you turn. Note: The Virginia Driver's Manual recommends signaling for three or four seconds before turning, which is especially appropriate at higher speeds. (At 40 mph, a vehicle will travel 100 feet in just 1.7 seconds, which is not much advance warning for that driver.)
