You are driving behind a long vehicle (as shown) which has a sign saying DO NOT OVERTAKE TURNING VEHICLE. The long vehicle indicates that it is going to turn left. You:

• A. May pass the truck because it cannot turn left from the middle lane.
• B. May move to the left-hand side of the road and pass the long vehicle.
• C. Must let the long vehicle turn first.
  Explanation:

  "Long vehicles may need to swing out wide to the right to make a left hand turn therefore you must not overtake it until it has made the turn."
