How does Bahrain's Traffic Law define the drink- and drug-driving offence, and what does a driver face on conviction?

1. It sets a permitted blood alcohol concentration of 0.08 per cent, below which no offence is committed
2. It prohibits taking an intoxicant or drug while driving, and driving under the influence to a degree that causes loss of control or impairs the ability to drive; conviction brings two months to one year in prison and a fine of BD 1,000 to BD 2,000, or either penalty, plus six months' administrative withdrawal of the licence
3. It applies only on roads with a limit above 40 km/h
4. It gives first-time offenders a written advisory notice
