Blow into this bag please Sir.

Didn't realise that a year or so ago, Scotland introduced a new drink-drive limit of 22 micrograms of alcohol per 100 millilitres of breath.  The limit in England and Wales remained at 35.  So this has created a strange situation where a driver in Scotland has been given a 12 month ban from driving for being found with a reading of 32, even though that reading would have been OK outside Scotland.  The point is that the ban applies throughout the UK, so he can't drive in England and Wales even though he would have committed no offence had he been stopped with that reading there.
