What must you do to prepare to turn left at a traffic control signal?

  1. Accelerate

  2. Look at the traffic

  3. Give the right-of-way

  4. Signal for a left turn

The correct answer is: Signal for a left turn

Turning left at a traffic control signal requires multiple steps to be done safely. First, you need to come to a complete stop when the light is red and wait for it to turn green. Then, turn on your left signal light to indicate to other drivers that you will be turning left. Next, check for any oncoming traffic to ensure it is safe to make the turn. Once it is clear, you can proceed to make the turn. This is why option A, accelerating, is incorrect. It is important to properly communicate your intentions with other drivers on the road, which is why option B, looking at traffic, is a good step to take but not the only one. Giving right-of-way, option C, is not necessary in this situation as the traffic control signal dictates who has the right-of-way. Overall, the correct answer is D because you need to signal for a left turn
