Red Cross
The signal indicates that the lane is closed
When You See This Sign
When you see a red cross over a lane you must not drive in that lane and you should change lanes as soon as it is safe to do so. Check your mirrors, signal, and move out of the marked lane at a controlled speed.
Rules & Regulations
- A red cross above a lane means the lane is closed and must not be used.
- If the cross lights up while you are already in the lane, you must change lanes as soon as it can be done safely.
- The signal applies to all vehicles using the marked lane and is issued by road traffic signals (e.g., bridge or tunnel portals and gantries over the carriageway).
- Also follow any temporary instructions (speed signs, directional arrows or diversion signage) that may complement the red cross.
Tips for Drivers
- Check your mirrors and indicate your intended lane change in good time with your turn signal when the cross lights up.
- Do not brake sharply in the lane when the cross lights up — instead move out in good time and reduce your speed in a controlled manner if necessary.
- Be extra vigilant in tunnels and on motorways where red crosses are often used for accidents or obstructions; follow traffic management instructions.
- If traffic is heavy and you cannot change lanes immediately, reduce your speed and leave the lane at the first safe opportunity.
Common Mistakes
- Thinking that a red cross is only a recommendation – it is a prohibitive signal and must be obeyed.
- Remaining in the lane or stopping in it to change lanes at the last moment instead of changing in good time.
- Confusing a red cross with a red traffic light and thinking you should stop where you are; with a red cross you should instead leave the lane when it is safe.

Exam Tip
In the theory test you may be given a multiple-choice question testing the difference between a red cross and a red traffic light — the correct answer is that a red cross prohibits the use of a specific lane, whereas a red traffic light requires a stop at a stop line or signal screen. Remember that the cross's meaning is binding for all vehicles in that lane.
Did You Know?
Red crosses are used mainly on motorways, arterial roads and in tunnels and are often controlled centrally by traffic management systems to quickly close a lane in the event of an accident, obstruction or roadworks. They are used together with variable speed signs to direct traffic safely.
Frequently Asked Questions
Does a red cross apply to all vehicles, including bicycles and mopeds?
The signal applies to the lane over which the cross is placed. If bicycles or mopeds use the same lane they are also covered by the prohibition; always follow the instruction for the relevant lane.
What do I do if the cross lights up and there is heavy congestion so I cannot change lanes immediately?
Brake calmly and adjust your speed so you can change lanes at the first safe opportunity. Do not remain in the lane to wait; leave it as soon as you can without creating a hazard.
Can I drive in a lane with a red cross if I'm only going a short distance?
No. A red cross means the lane is closed regardless of how far you intend to travel in it. Make a safe lane change before continuing.
What happens if I ignore a red cross?
Driving in a closed lane is a traffic offence and may lead to fines or other penalties and increases the risk of an accident. In addition, you may endanger work vehicles and emergency services carrying out operations.
