Driving in France
Since 1st July 2008, all vehicles in France have to carry a fluorescent waistcoat (gilet fluorescent) and a warning triangle (triangle de signalisation).
Visibility vests (it is recommended to have at least 2 or one per driver and passenger) have to be put on before getting out of the car in the event of a breakdown so they have to be kept inside the car (under the seats or in glove box) and not in the boot.
If you get stopped by the police, you will get fined if you don’t carry those items in the car.
Waistcoats and warning triangle can be bought from garages or supermarkets in France.
