A puncture on a French motorway is one of the most dangerous places to break down, and the rules here are stricter than many visitors expect. If a tyre lets go on the A7 south of Lyon, the A8 along the Riviera or the A10 down the Atlantic side, your first job is not to fix anything — it is to get yourself safe.
The first 60 seconds
As soon as you feel the car pull or hear that tell-tale flapping, ease off the accelerator, do not brake hard, and signal towards the hard shoulder (la bande d'arrêt d'urgence). Bring the car as far right as you can, ideally behind a crash barrier, and switch on your hazard lights straight away.
- Everyone gets out on the passenger side, away from traffic.
- Put on your high-visibility vest (gilet jaune) before you step out — it is a legal requirement and it must be kept inside the cabin, not the boot.
- Place the warning triangle around 30 metres behind the car, only if it is safe to walk there.
- Get everyone, including children and pets, over the barrier and well away from the carriageway.
Who to call on a French motorway
On the motorway you should always call for help from a position of safety. There are two ways to do it:
- Use the orange SOS phone. These are spaced roughly every two kilometres and connect you directly to the motorway control centre, who can pinpoint your exact location.
- Or dial 112, the European emergency number, which works from any mobile and in English.
French motorways are privately operated, and on the motorway itself only the official, authorised operators are allowed to attend a vehicle on the hard shoulder. That means no private firm — including us — can legally pull up next to you on the live carriageway. It is not red tape for its own sake; it genuinely keeps you alive.
Where a mobile fitter fits in
This is the part visitors often misunderstand. A mobile tyre service cannot meet you on the hard shoulder of the A7, A8 or A10. What we can do is meet you at the next exit or the next aire (service area) once you are safely off the live motorway. If your car is still drivable at very low speed for a short distance, or once the official operator has moved you to a safe area, we come to you there with the right tyres and fit them on the spot.
Repair or replace?
Motorway debris often causes a clean puncture in the tread, which can usually be repaired with a plug or an internal patch. If the tyre has run flat for any distance, or the damage is in the sidewall, it cannot be repaired safely and must be replaced. Remember that in France tyres are fitted in pairs across an axle, so you would replace two rather than one — it keeps the car balanced and predictable, which matters most at motorway speeds.
A word on hire cars
Most hire cars in France carry only a foam sealant kit, not a spare wheel. Sealant can sometimes get you to the next exit with a small tread puncture, but it does nothing for a blowout or a gashed sidewall. If that is your situation, get to safety, call the rental company to log the incident, and arrange replacement tyres to be fitted where you have stopped.
Keep it simple and stay calm
To recap: slow down smoothly, pull onto the hard shoulder behind the barrier, vests on, everyone out on the safe side, triangle out, then call 112 or use the orange SOS phone. Do not attempt a wheel change next to live traffic. Once you are safely at an exit or aire, that is where we take over.
