What can happen if my breathalyser isn’t NF Approved?
The worst that can happen if your breathalyser isn’t NF approved is that you will be stopped by the police and fined for carrying no breathalyser equipment. If you are over the legal limit for blood alcohol levels too, then you will be arrested and taken to a police station for further testing, just like the UK.
You can plead that your breathalyser gave the ‘all-clear’, but if it does not correspond to the French test equipment readings then you are at risk of imprisonment for drink-driving and a hefty fine.
For peace of mind, choose a breathalyser that is NF approved as these are certified to have the required accuracy.
