When you get ready to leave an expressway, you should begin to use your turn signal:

  1. Just as you get to the exit ramp
  2. 50 feet before the exit ramp
  3. 100 feet before the exit ramp ✓
  4. When you see cars behind you in the exit lane

Answer: C. 100 feet before the exit ramp

You should begin using your turn signal at least 100 feet before the exit ramp.

Why this is the answer

The New York manual says to check the signs and get into the correct exit lane ahead of time. It then says to signal your exit at least 100 feet (30 m) before you reach the exit ramp. That makes the 100-foot choice correct. The manual also says to slow down once you are on the ramp, so the signal comes before you reach the ramp, not after you are already on it.

Why the other answers are wrong

Remember it

Signal before the ramp, not on it: at least 100 feet early.
