Of all the questions I get asked about driving in France, "do I need to take breathalysers" is the most common.
Legally they are still listed as a requirement so by not taking them you are technically breaking the law but there is no fine for not carrying them. Most "British" people still buy them though because that's what we are like!
You can buy them on this page (a twin pack of NF approved ones) if you wish and to put peoples mind at rest we include them as part of our All In One Travel Kit.
PLEASE NOTE: The image below may not exactly match the breathalysers we have in stock right now. We constantly turn over large quantities of breathalysers and each time the new stock comes in the packaging is likely to change. We always have up to date (long use by dates) French NF approved ones so you can be sure your are fully regulation compliant.
