What should I do if I have an accident or break down?

Published on 16.09.2021

In the event of an accident, or if you break down, your safety and that of others is of the utmost priority. Here is a reminder of the rules to follow, depending on the circumstances.

The traffic police and road safety officers regularly remind us that accidents and breakdowns can happen, and that it is vital, in such cases, to know exactly what to do to avoid causing a multi-vehicle collision.

Secure the area and the people involved

  • If it is possible to move the vehicle(s), the best thing to do is to clear the road, but not without first taking photos, in the event of an accident, as this will help you to complete the accident report form (see our previous article on this subject).
  • Whether you have broken down or been involved in an accident, the first thing to do is to ensure your safety and that of your passengers by putting on a safety vest as soon as you leave the vehicle and by switching on your hazard lights.
  • If the vehicle(s) is/are immobilised, secure the area with a warning triangle so that motorists can identify the hazard and adapt their driving accordingly.
  • If there are injured parties, the golden rule is not to move them unless absolutely necessary (e.g. if the car is on fire). Contact the emergency services on 112 or 113 immediately and look after any injured parties until the fire brigade arrives.
  • If there are no injured parties, once you have secured the area and the people concerned, move to a safe place away from the traffic to complete your report. In the event of a disagreement between the parties, call 113 to speak to the police, who will assist you. If you are unable to continue your journey with your vehicle, contact our roadside assistance service, which will send a technician or a recovery vehicle out to you. Consider using our ACL App and its eCall Mobile function to make it easier for them to assist you.

On the motorway

  • In the event of an accident, the same procedure applies as on any other road or in a town or city.
  • In the event of a minor technical problem, avoid blocking the hard shoulder if you can get to the nearest exit and deal with the breakdown there. Otherwise, park your vehicle as far to the right as possible on the hard shoulder and switch on your hazard lights.
  • Never stay in your vehicle, even if the weather is bad. Ensure that all passengers are wearing a yellow vest, have them leave the vehicle via the right-hand side and stay behind the guardrails. Do not try to stop vehicles, and do not go out into the lanes of traffic or walk along the hard shoulder. 
  • Call the 113 emergency number.  Return to your vehicle, again ensuring that you stay behind the guardrail, and wait behind it for help to arrive. Do not get back into your vehicle.
  • Never try to repair your vehicle or change a wheel in the emergency lane. Luxembourg law prohibits the carrying out of repairs on the public highway. (A 160-15).
  • Under no circumstances should you abandon your vehicle, but instead call for a recovery vehicle from the ACL to get your vehicle out of the way as quickly as possible.

In a tunnel

  • Switch on your hazard lights and, if possible, drive your vehicle out of the tunnel. If this is not possible, park the vehicle in a safety recess, on the hard shoulder or, failing that, as far over to the right as possible. Turn off the engine and leave the key in the ignition.
  • Leave the vehicle via the right-hand side and put on your safety vest. Go to the nearest SOS point and notify the control centre using the emergency phone (not your mobile phone). Stay there until help arrives. Do not try to stop vehicles on the motorway by going out into the lanes of traffic or walking along the hard shoulder.
  • Call an ACL recovery vehicle to get your vehicle out of the way as quickly as possible.
