Alcohol Legislation

UK Driving Limits (excluding Scotland) for a standard driving license and vehicle.

The legal alcohol limit in the UK varies in different parts of the UK and also by occupation. Professional drivers are subject to lower legal alcohol limits.

In England the legal alcohol limits for car drivers on a standard driving license are as follows:

  • Blood Test - 80 milligrammes of alcohol in 100 millilitres, 80mg/ml, 0.08 BAC, 0.8 Promille 
  • Breath Test - 35 microgrammes of alcohol per 100 milliliters of breath BrAC

Drink drive limits for professional drivers and operatives in UK

  • Blood test - 20 milligrammes of alcohol in 100 millilitres, 20mg/ml, 0.02 BAC, 0.2 Promille
  • Breath test - 9 microgrammes of alcohol per 100 milliliters of breath (BrAC) 

Under the Railways Transportation Safety Bill, the UK government introduced lower drink drive limits for those working in the transport industry.

The drink drive limit for professional drivers and operatives is just 0.02% - one quarter the UK Drink-Drive limit of 0.08% and the lowest detectable level possible allowing for the residual levels that can exist in anyone whether they've been drinking or not.

The lower drink drive limits in UK also apply to pilots, cabin crew, air traffic controllers, aircraft engineers, train drivers, and commercial seamen.

Zero means below detectable levels. Aggravated indicates additional penalties associated with higher BAC or associated driving offence. 

All these levels are subject to regular review and change, please check with the country for current legislation in operation before travelling.
