As from July 1st all drivers visiting France will need to carry a breathalyser in their cars, the rules apply to anyone travelling to or through France by car in the summer holiday season even just for a day trip.
IAM ( the Institute of Advanced Motorists) is advising motorists in France to have at least two breathalysers at all times, so that if one is used you still have one to produce for the police if you are stopped. Neil Greig, director of policy and research said “the new French rule is a genuine attempt to reduce the number of alcohol related-accidents. France’s lower limit means it’s very easy to be over the limit the morning after as well. As always, the best advice for motorists is not to drink and drive at all.”
The legal limit in France is 50 mg per 100 ml of blood; lower than in the UK (the UK limit is 80mg). The breathalysers cost between £1 and £2 and will be available at ferry and tunnel terminals for crossings to France. It is intended that people will be able to test themselves to check whether or not they are over the French limit. Single-use breathalyser kits will satisfy this requirement.
