Warning for Traffic Light
The sign indicates a location where traffic is controlled by a traffic light with three light signals.
When You See This Sign
When you see the sign you should immediately reduce speed and prepare to stop if the signal turns red. Watch the light changes and position yourself in the correct lane without making sudden lane changes.
Rules & Regulations
- The sign warns of a multi-colour signal with three light openings; you must obey the signal's instructions — red means stop at the stop line or before the pedestrian crossing.
- The warning sign itself does not change yielding rules or priority; it only reminds you that traffic is controlled by traffic lights ahead.
- Adjust your speed so that you can stop safely if the signal shows red or changes to yellow; also keep a safe distance to the vehicle in front.
- If the traffic signal is out or malfunctioning, normal right-of-way rules or any temporary instructions from traffic signs, road markings, or a person directing traffic apply.
Tips for Drivers
- Reduce speed in good time and read the signal as you approach — a yellow light means you should stop if it can be done safely.
- Avoid overtaking near signal-controlled intersections because vehicles ahead may brake suddenly at red.
- Pay extra attention to pedestrians and cyclists at crossings; the traffic control may include separate pedestrian and bicycle signals.
- Get into the correct lane in good time and avoid late lane changes so you don't risk blocking the intersection if the light changes.
Common Mistakes
- Believing that the warning sign itself gives priority or changes the right-of-way rule — it does not.
- Misinterpreting the sign as applying only to motor vehicles and forgetting that pedestrians and cyclists are also covered by the signals ahead.
- Starting to accelerate on a yellow light instead of assessing whether it is safe to stop — you must stop at yellow if it can be done without danger.

Exam Tip
On the theory test you may be given a question that tries to make you believe the sign gives priority or an automatic stop-like effect — answer that it is a warning and that you must follow the actual traffic lights when you arrive.
Did You Know?
The A22 warning sign is often used on higher-speed roads or in outlying areas where a traffic light is not expected, to give drivers extra time to react. The sign emphasizes that it is a traditional three-light traffic signal and not a simple pedestrian signal.
Frequently Asked Questions
Do I always have to slow down when I see the sign?
Yes, the sign warns of a signal and you should adjust your speed so that you can stop if the light turns red. There is no fixed speed limit associated with the sign, but you must be able to stop safely.
Does the sign also apply to cyclists and pedestrians?
The sign warns all road users of an upcoming multi-colour signal that controls traffic. Both cyclists and pedestrians must obey the signals posted at the location.
What do I do if the traffic lights are out or broken?
If the signals are not working, the normal right-of-way rules and any road signs or instructions from traffic direction apply. Drive carefully and show consideration because other road users may be uncertain.
Does the sign mean I am not allowed to overtake?
The sign does not prohibit overtaking in itself, but overtaking near a signal-controlled intersection is inappropriate and risky. For safety reasons you should avoid overtaking when approaching a traffic signal.
