Policy in detail: Drink drive limit

We are progressing plans to bring in a lower drink drive limit in Scotland.

It is estimated that just over one in every nine deaths on Scotland’s roads each year involve drivers who are over the legal drink driving limit. This equates to around 30 deaths every year.

We consulted on proposals to lower the drink drive limit in 2012. Almost three quarters (74 per cent) of respondents were in favour of a lower drink drive limit.

The current drink driving limits are:

  • 80 mg of alcohol in every 100ml of blood
  • 35 mcg of alcohol in every 100 ml of breath
  • 107 mg of alcohol in every 100 ml of urine

We are proposing:

  • a reduction in the blood limit from 80 mg of alcohol in every 100 ml of blood to 50 mg of alcohol in every 100 ml of blood
  • an (equivalent) reduction in the breath limit from 35 mcg of alcohol in 100 ml of breath to 22 mcg of alcohol in every 100 ml of breath
  • an (equivalent) reduction in the urine limit from 107 mg of alcohol in 100 ml of urine to 67 mg of alcohol in every 100 ml of urine
