What is the recommended action if your vehicle stalls in a busy tunnel?

The recommended action if your vehicle stalls in a busy tunnel is to use the emergency phone for assistance. This is the safest and most effective way to get help in such a situation. Tunnels are typically designed with emergency phones at regular intervals specifically for scenarios like this, allowing you to alert tunnel authorities and receive immediate assistance while also ensuring the safety of other road users.

Using an emergency phone ensures you are communicating with professionals who are equipped to handle emergencies and can take the necessary actions to assist you and manage the situation within the tunnel. Moreover, it reduces the risk of putting yourself in danger by attempting to physically signal for help or restarting your vehicle in a potentially hazardous environment.

In busy tunnels, other choices, like signaling for help to passing vehicles, may not be safe or effective, as it could distract drivers or create further hazards. Trying to restart the car can also lead to additional risks, especially if it is safe to exit the vehicle. Leaving the vehicle should only be considered in specific extreme circumstances, such as a fire or if instructed by emergency personnel. Overall, using the emergency phone is the best course of action to ensure your safety and the orderly management of traffic within the tunnel.
