If your vehicle breaks down or you crash in a tunnel
- If possible drive out of the tunnel. If not possible, pull over to a breakdown bay or the side of the lane.
- Stay in your vehicle unless otherwise advised.
- Switch on your hazard lights.
- Wait for help to arrive.
- You will be monitored by cameras and assistance will be sent to tow your vehicle.
- If you need to call for help, it is preferred that you use the emergency phones as they will automatically identify your precise location within the tunnel. The tunnel control room will contact emergency services if necessary.
- If you suspect your vehicle is malfunctioning do not enter the tunnel.
CAUTION – before you get out of your vehicle, check for approaching traffic.
What if you are caught in traffic?
- Turn on your radio – emergency broadcasts may be transmitted and will cut into your normal station.
- If instructed, turn off your engine. Idling for extended periods produces higher levels of pollutants.
- Vehicle emission levels are monitored continuously in Sydney's major tunnels and tunnel operators ventilate the tunnel to air quality standards.
