As of the 1st July 2012 you need to have them in your car. Does anyone know where to buy them?

If this is the case I'd suggest they'll be a flood of them onto the market and most big supermarkets and petrol stations will stock them - well thats what happened when warning triangles and jackets came in.....fingers crossed.

Auchan are selling them as a double pack. I think that they were €2.20 for the pair.

The pharmacies are selling them, I bought mine for one euro the kit. Some tabaco shops will have them, and you will find them in some supermarkets too. Give it a couple of weeks, they will surely be sold in big packs soon!

Will it be possible to buy multi-use ones, or are they all single use?

Which raises a question ??? If you blow yourself and it is okay to drive, and the police stop you and it is over the limit where do you stand !!! It is a grey area, it is almost giving you a green light to drive after a drink on the results from a one euro test from a supermarket !!!
Does anyone know the exact law on this and what it is actually trying to achieve?

Hi unclebuck,

This link tells you about the law - http://www.preventionroutiere.asso.fr/Fil-d-information/Ethylotest-obligatoire-dans-les-vehicules-un-point-sur-le-nouveau-decret

It says the kits must be 'single use only'.

The fine is 11 euro if you can't produce a kit, if stopped by the police. While the law comes into force in July 2012, there is a period of grace until November in that they won't fine you before November, just give you a warning up to then.

What they actually hope to achieve is a good question, but I can only assume that that since alcohol is a major cause of fatal accidents on the roads the authorities are trying to get drivers to be much more aware of the dangers of drinking and driving. Keeping multiple kits in your car is an added incentive, if drinking, to take a test before driving, and if over the limit, obviously not drive.

It also means of course drivers pay for the test, not the police, as is the case up to now.
