Difficulty: EasyTraffic Lights and Signals

You are waiting at a junction controlled by traffic lights. The main circular light is showing red, but a green filter arrow pointing to the left is illuminated. What should you do if you intend to turn left?

  1. A
    Remain stationary behind the stop line until the main circular light turns green
  2. Proceed in the direction of the arrow if the way is clearAnswer
  3. C
    Flash your headlights to demand priority over oncoming traffic before turning
  4. D
    Follow the vehicle directly ahead through the junction without looking for emerging hazards

Answer

Proceed in the direction of the arrow if the way is clear.
According to the Highway Code, when a green filter arrow is illuminated alongside a red main signal, drivers intending to travel in the direction of the arrow may proceed, provided the way is clear and they give way to any pedestrians or vehicles already crossing the junction.

Step-by-Step Solution

1
Identify the meaning of the illuminated green filter arrow
Recognise that a green filter arrow gives permission to travel in the direction indicated, even while the main circular traffic light is red.
Highway Code Rule 177 establishes that filter arrows allow specific traffic flows to move independently of the main signal phase.
2
Assess the junction for safety and clear path
Check that the destination road and pedestrian crossings are clear before making the manoeuvre.
Traffic signals give permission to move only when it is safe to do so.
