Respect the tunnel’s speed, spacing and signals. Identify exits and equipment; a closure or operator instruction takes precedence over navigation.
Approaching the entrance
Observe signs, open lanes and traffic conditions before entering. Switch on suitable lights according to instructions and increase margins. Check available energy before a long crossing: do not rely on an improvised stop inside the structure.
During the crossing
Maintain regular spacing and observe lane signals. Do not change lanes against markings or instructions. Stated distances can depend on the tunnel and vehicle; do not generalise a value from a different structure.
Slowing traffic or a breakdown
Follow instructions and do not close up to the preceding vehicle. A breakdown, queue and fire require different responses. Identify emergency signs and use the provided alert systems, which let the operator locate the incident.
When evacuation is requested
Follow signs to identified exits and the operator’s instructions. Do not return for luggage or turn around to try to leave through the entrance. This guide gives references; instructions displayed in the tunnel specify the actions to take.
Traffic slows sharply in a tunnel.
Respect signals and spacing, keep emergency access clear and observe operator instructions. During an incident, use the alert systems and instructions displayed there.
What to avoid. An emergency exit and a technical door are not interchangeable: follow the signs.
Practical checks
- Respect entrance signals
- Maintain prescribed spacing
- Identify exits and equipment
- Follow evacuation instructions
Common questions
Does the same gap apply in every tunnel?
Follow the structure’s signs and rules applicable to your vehicle.
Can I turn around in a traffic queue?
Do not attempt that manoeuvre. Respect lanes, signs and operator instructions.
Should I always leave the car in a queue?
A queue is not an evacuation. Follow instructions; a danger or evacuation order changes the response.
