Rescue protocol for broken-down vehicles in tunnels

Rescue protocol for broken-down vehicles in tunnels

Tunnels present unique challenges and high risks for roadside assistance operations, especially single-bore tunnels. 

In these scenarios, safety is paramount. Below, we describe the procedure a roadside assistance operator must follow to rescue a broken-down vehicle in a tunnel, ensuring both their own safety and that of road users.

Communication with the traffic management centre

Before entering a non-toll tunnel, the operator must contact the traffic management centre. It is crucial to provide accurate information: the name of the tunnel, the road, the kilometre point and the exact direction. This information will allow the management centre to activate the warning signs and, if necessary, close the tunnel to facilitate the rescue operation.

Approaching the tunnel

When approaching the tunnel, the operator must reduce speed and pay maximum attention. The tunnel entrance may be congested, and the transition to a less well-lit environment can reduce visual perception. These conditions require cautious driving to avoid further accidents.

Positioning and loading the broken-down vehicle

Once the broken-down vehicle has been located, if it is blocking the lane, the operator must wait until there is no oncoming traffic before positioning the tow truck in front of the vehicle. It is vital to load the vehicle safely and quickly, securing it properly before leaving the tunnel. The exit can be particularly dazzling on sunny days, so caution is needed.

Ban on repairs inside the tunnel

Carrying out any kind of repair inside the tunnel is prohibited, even if the vehicle is in a lay-by. Instead, the vehicle must be loaded onto the tow truck and taken out of the tunnel to a safe place, such as a car park or rest area, where the necessary repairs can be carried out.

Procedure in private toll tunnels

In private toll tunnels, the procedure is similar, except that the initial notification is made by the private operator to the assistance service. When entering the tunnel from another entrance, it is essential to notify the coordination centre so that they can activate the signs and close the tunnel if necessary.

Precautions in winter

During winter, in high-mountain tunnels, low temperatures and dripping water can form icicles on the ceiling. The operator must wear a helmet at all times inside the tunnel to protect against falling ice.

In the event of an accident or breakdown in a tunnel, the following steps must be taken:

1. Switch on the hazard lights.
2. Try to move the vehicle to an emergency stopping area or onto the hard shoulder.
3. Switch off the engine and signal the vehicle with warning triangles.
4. Leave the vehicle and, in the event of an accident, help the injured.
5. Call for help from an SOS post.

In the event of a vehicle fire in a tunnel:

1. Switch off the engine.
2. Use the extinguisher, opening the bonnet just enough to insert the extinguisher hose and direct it at the fire.
3. Use the tunnel's extinguishers if possible.
4. Leave the vehicle immediately, moving it to the side if it cannot be driven out of the tunnel.
5. Call for help from an SOS post and head for the emergency exit as soon as possible.

Following these protocols not only guarantees the safety of the roadside assistance operator, but also that of all tunnel users. Efficient coordination and appropriate safety measures are essential for handling emergencies in these high-risk environments.
