Tunnel and road safety
- What should I do if my vehicle breaks down in a tunnel
What should I do if my vehicle breaks down in a tunnel?
As well as offering motorists travel time savings and reliability, travelling on the go via network also provides motorists with the added safety and security of a 24 hour incident response service.
If you're involved in an incident, 24/7 safety cameras will alert our control room operators and we’ll send out an incident response unit to assist you right away.

If you break down in a tunnel you should:
- drive out of the tunnel or if this isn't possible try to stop in a right or left lane (not the centre lane)
- switch on your hazard lights and radio
- stay calm and wait for the incident response unit which will attend to you as quickly as possible
- if you need to call for help use your mobile phone to call go via on 13 33 31, or you can use one of the emergency phones located along the tunnel walls
- remain in your vehicle unless there’s a fire or you're asked to evacuate by the control room
- if you do have to get out, watch carefully for other traffic and move to either the walkway or in front of your vehicle, never behind it
- in an evacuation, look for the running man symbols and flashing lights for a safe exit point
Try to stay calm and remember that our extensive CCTV coverage means operators can spot incidents and will help you out as quickly as possible.
- Tips for safe tunnel driving
Breakdowns and incidents in tunnels can disrupt traffic and be a safety hazard.
- switch on your lights – to improve your vehicle’s visibility
- avoid unnecessary lane changes – to reduce the risk of collision
- listen to your radio – a radio re-broadcast system is in place to enable tunnel operators to broadcast important/safety messages over a vehicle’s radio
- Obey vehicle restrictions
- If you breakdown switch on your hazard lights and remain in your vehicle unless you are otherwise instructed; an incident response vehicle will be dispatched to assist you as quickly as possible.
