The fines were due to be enforced from 1 November 2012.

All drivers in France, including motorcyclists, are now required to carry a breathalyser kit otherwise the €11 fine will be applicable to all road users, except for those on mopeds.

Neil Greig, IAM 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 road users is not to drink and drive at all.”

Single-use breathalyser kits will satisfy the requirement. The legal limit in France is 50 mg per 100 ml of blood, lower than in the UK. The UK limit is 80mg.

Brits heading to France over the half-term break should make sure that they have a kit that satisfies the requirements.

Each kit costs between £1 and £2 and are available at ferry and tunnel terminals for crossings to France.

Anyone driving in France is already required to carry a warning triangle and a fluorescent safety vest to use in an emergency.

Additionally UK motorists and motorcyclists must display a GB plate.

The French government was set to make €20m out of over 50s driving abroad had the fines been enforced this year, as industry experts had predicted that some drivers will still fail to take steps in line with European driving regulations.
