How to drive safely through tunnels

Before Entering a Tunnel
Preparation is key. As you approach, take a moment to get yourself and your vehicle ready:
Choose your lane early. Avoid last-minute changes by positioning yourself well in advance.
Switch on your headlights. Even in bright daylight, tunnels can be very dark. You need to see and be seen.
Watch for changing speed limits. Speed restrictions often alter near tunnel entrances, so stay alert to any signs on the approach or mounted above the lanes.
Stay informed. Keep your radio tuned to local traffic updates and check any electronic information boards for incidents or closures ahead.

Once inside, stay calm and focus on smooth, steady driving:
Maintain a safe following distance. This gives you time to react if traffic suddenly slows or stops.
Keep your speed consistent. Avoid unnecessary acceleration or braking.
Stay calm. If tunnels make you uneasy, remind yourself that it’s only a short section of your route. Picture your vehicle safely exiting at the other end.

Should your vehicle develop a fault:
Move to the left-hand side as safely as possible.

If you notice smoke or flames:
Put on your hazard lights and stop well back from the fire.
Turn off your engine.
If the fire is large or spreading, leave your vehicle immediately and follow the illuminated emergency exit signs to safety.
Raise the alarm using an emergency phone or call for help once you’re clear of danger.
Remember:
Calm, steady actions and good preparation make tunnel driving safe and straightforward. Stay alert, follow signs, and keep your focus – you’ll be back in open air before you know it.
