Question 3248

The traffic light on the right is green and the one on the left is red. What must you do to continue straight ahead?

  1. Continue straight ahead because the one on the right allows me to.
  2. Wait until both turn green.
  3. Stop and wait for the one on the left to turn green.
Show answer and explanation

Correct answer: Stop and wait for the one on the left to turn green.

If the traffic lights on the right and left show different indications, drivers who want to continue straight ahead or turn left must obey only the light on the left. If it is red, they must stop and wait for it to turn green; changing lanes is not necessary.
