Costs for the simple balloon-type are no more than €1.50. They should carry the NF (Norme Française) logo and should be changed every two years.
Also make sure that you get the right ones as the limit in France (.5 mg per ml) is lower than that for the UK (.8 mg per ml).
France has recently invested in many more speed cameras, fixed and mobile. While I have not heard of anyone from the UK being fined as a result of going through a fixed camera, doing so, in excess of the speed limit, through a mobile one can mean being stopped and having to pay an instant fine of € 90. If you do not have the cash, they can take your driving licence away and only return it once you have visited the nearest town and the nearest cash machine.
Be aware that there are 400 new, unsigned fixed speed cameras are currently being installed throughout the country and signs for existing cameras are being taken down. Keep to the speed limits if you don't want an on the spot fine! They are also reported to have vehicles which can check the speed of vehicles in both directions.
The speed limits are:-
Autoroutes 130 kph (110 when raining) (approx 80/70 mph)
Dual Track 110 kph (approx 70 mph) (where so marked)
Single Track 90 kph (approx 55 mph)
Outskirts of towns 70 kph (approx 42 mph)
Towns 50 kph (approx 30 mph)
Near Schools 30 kph (approx 20 mph)
KIT TO BE CARRIED
French Law demands that you have on board a first aid kit, a set of spare light bulbs, a red warning triangle, they also recommend a fire extinguisher. You must also have, within reach of the driving position a florescent yellow jacket for the driver. Failure to carry all of these can result in an on the spot fine.
Dipped headlights must be used in poor visibility during the day.
The Gendarmes are also tightening up on not stopping at “STOP” signs. Here, you are expected to come to a complete halt irrespective of whether the road is clear, and be there for at least 3 seconds – failure to do so is a fine of €90.
Payages on Autoroutes take cash and credit cards. For details of the charges click on
There is also the facility of buying a tag to use on the French Motorway system.
