you are about to make a left turn. you must signal continuously during the last ____ feet before the turn.

The correct answer is: 100 feet.

Required signaling distance

• For typical DMV written-test questions in the U.S., you must signal continuously during the last 100 feet before making a left (or right) turn.

• Some driving guides and state laws note that this 100‑foot rule is standard for city or low-speed roads, with longer distances sometimes recommended at higher speeds, but the test answer remains 100 feet unless your specific handbook states otherwise.

So, if you see the question:

“You are about to make a left turn. You must signal continuously during the last ____ feet before the turn.”

You should fill in: 100.
