Have a zero tolerance level for drink driving for everyone. Solves the drink drive issues as it is crystal clear.
Limit young drivers (or maybe all drivers who have just past their test) to a maximum speed of 40MPH for three years. Probably better ban them from motorways during this period.
Zero tolerance, I agree.
Limit ALL young drivers to 40mph is frankly, a poo idea. For 3 years?!
Lets see how happy you'll be if I'm driving 40mph in a single country lane with a national speed limit sign up? (maybe a bad example) but it isn't the way forward.

Young drivers kill themselves and others on narrow roads with National Speed Limit signs as the don't have the experience. I probably wouldn't like it but the fact is that young drivers don't have the skills and experience and have far too much confidence and the tendency to show off to their mates.
