Question to the Department for Transport:

To ask Her Majesty’s Government what assessment they have made of the risk of a driver's involvement in a collision involving injuries or death when they have a blood alcohol concentration of 80 milligrams of alcohol per 100 millilitres of blood or more; and how that assessment of risk compares with that made when the alcohol limit for drivers was set in 1967.

Sir Peter North’s 2010 Review of drink and drug driving made an assessment of various studies. The Coalition Government responded in March 2011 by setting out its position on maintaining the current limit. This Government agrees with that assessment and we do not believe any further studies have provided sufficient evidence to change that position. There are therefore no plans to change the current laws.
