Question 7117

When must a vehicle that is changing lanes to pass turn off its turn signal?

  1. When it has completed the lane change.
  2. When it returns to the right lane.
  3. When it has gone past the vehicle and before moving back to the right.
Show answer and explanation

Correct answer: When it has completed the lane change.

Turn it off as soon as you have finished moving over, meaning when you are traveling straight in the left lane. Keep it off while passing alongside the other vehicle. To return to your lane, turn on the right turn signal and turn it off again once you are in that lane. In the image, the red passenger car is already in the left lane with its turn signal still on, so it is time to turn it off.
