Tunnel (Tunnel)
The sign warns of a tunnel.
When you see the sign
Adjust your speed before the tunnel entrance, and be prepared for reduced visibility and the rapid transition between daylight and darkness. Check that your dipped headlights and rear lights are on, and keep a safe distance from the vehicle in front. Follow the speed limit, lane signals and other signs in the tunnel.
Rules
- The sign warns of a tunnel ahead, but does not itself impose any requirement or prohibition.
- The sign does not automatically change the speed limit; the current or separately posted speed limit applies.
- You must use the required lights while driving and must avoid dazzling others with high beams.
- Stopping or parking in a tunnel is prohibited unless the stop is caused by traffic conditions or is necessary to avoid danger.
Tips
- Remove your sunglasses before entering, so your eyes can adjust to the darkness more quickly.
- Switch on the dipped headlights manually if you are unsure whether your car's automatic lighting also turns on the rear lights.
- Reduce your speed before the tunnel entrance instead of braking hard just after entering.
- Watch for lane signals, emergency exits and the distance to the vehicle in front.
Common misconceptions
- Some people confuse the symbol with the sign for a narrower road, but this sign shows a tunnel entrance.
- The sign does not mean that the speed limit automatically becomes lower.
- An emergency lay-by in a tunnel is not an ordinary rest area or a place to make phone calls.

Theory test tip
A common trap is to assume that the sign warns of a narrower road or introduces a specific speed limit. The symbol only warns of a tunnel; any speed limit is shown by a separate sign.

Frequently asked questions
Do I have to reduce my speed when I see the sign?
The sign does not require any specific reduction in speed. However, you must still adjust your speed to the visibility, the tunnel's design, the traffic and the applicable speed limit.
Which lights should I use in the tunnel?
Use dipped headlights and check that the rear lights are on. High beams may be used when conditions permit, but must not dazzle other road users.
Can I stop in the tunnel to use my phone?
No, ordinary stopping and parking in a tunnel are prohibited. An emergency lay-by should only be used in the event of a breakdown, illness or another emergency.
What should I do if my car breaks down in the tunnel?
Try to reach an emergency lay-by or pull as far to the side as is safe, and switch on your hazard warning lights. Follow the tunnel's emergency signs and instructions, and use the emergency telephone if one is available.
