What happens if neither of the drivers has an accident report?

If neither of the drivers has an accident report, then simply use a blank sheet of paper, put down all the information you can under the headings ‘ insured’, ‘driver’, ‘vehicle’ and ‘insurer’ as well as the circumstances of the accident. And above all, do not forget the signatures of both parties.
So make sure you always have a copy in the glove compartment of your car or with your vehicle documents. If you don’t have one now, ask your insurer for a copy or ask LALUX directly (groupeLL@lalux.lu). There will be no charge.
