The best thing they did was lower the limit for drink driving in Scotland so that you really can’t have a drink at all without being over the limit so you can’t think a small drink will be ok. As I understand it, the only reason it isn’t zero is to allow for some medications which have small amounts of alcohol present. Driving the next morning is something I think a lot of people need educationing about, some people seem to think that because they’ve been to bed they’re fine the next morning.
