It has been said that the proposals to reduce the alcohol blood level from 80 to 50 milligrammes would have little effect on the drinking habits of the majority of drivers except that more drivers would have criminal record if conficted.
However, if we consider an extreme scenario in which the drink driver was involved in "an accident" in which a person died or was crippled, they should be charged, and tried wth the vehicle being considered as a weapon.
Would this prove to be a deterrant against drink driving? Possibly.
By charging a drink driver with an offence commensurate with the alleged offence and considering the vehicle to be a weapon, may be another way to convince drivers who have had one or more drinks to leave the keys behind.
