Drink-drivers in France will be able to avoid a ban if they install breathalyser "alcolocks" that prevent their vehicles from starting if they are over the legal alcohol limit.
Those convicted of the offence will have to blow into the breathalyser before the engine will start. They will then be required to blow a second time — set randomly at between five and 30 minutes later — to check that they are still under the limit, with the aim of preventing someone else starting the car for them.
The Government approved the measure this week after a year-long trial in seven French departments.
Drivers "lose" points from a total of 12 on their licence, and drink-driving incurs a penalty of six. For a driver to lose their licence for half-a-year, they must lose the remaining six points.
The authorities will be empowered to order drink-drivers with a blood-alcohol level between 0.8 and 1.8g/l to install "alcolock" breathalysers at their own expense as an alternative to a ban.
