You are driving in a tunnel and approach the end of a traffic jam. What do you do?

When you drive in a tunnel and encounter the end of a traffic jam, you should switch on your hazard warning lights. This alerts drivers behind you to the danger of a sudden stop, reducing the risk of rear-end collisions—especially important in tunnels where visibility can be limited. Making a U-turn or leaving your vehicle in a tunnel is dangerous and generally prohibited except in emergencies. Always stay in your vehicle and keep it ready to move unless authorities instruct otherwise or there is immediate danger, such as fire. By following this rule, you help maintain safety for yourself and all other tunnel users.
