So if you only carry one breathalyzer, you have a drink, use the kit which shows negative, drive off, get pulled up and fined for not having a kit.
But if you decide not to use it, you still test negative on the police kit but have no penalty because you still have the kit. Sounds like another law that hasn't been thought through.
However, If you're saying the law is that you carry ONE, then that's what I'm interested in, I wouldn't risk driving over there after drinking anyway. But I'm concerned that the BBC are yet again quoting incorrect facts, they definitely said this morning you need two and although it is not repeated in Sprockets link, it is on the Channel 4 News :-
Car accessory retailer Halfords said it is selling one kit every minute of the day, and has rushed extra stock into stores to cope with the unprecedented demand.
Six out of 10 Britons travelling to France are not aware they have to carry two French government-approved breathalysers - showing the symbol NF - at all times, according to the company.
