From 5 December 2014 the blood–alcohol limit has been reduced from 80mg in every 100ml of blood to 50mg in Scotland.
In practical terms this means that someone drinking alcohol and driving could be ‘over the limit’ to drive after a relatively small amount of alcohol.
As the normal method of checking how much alcohol is in your system is a breath test you should be aware that the new limits for the breath test are 22 micrograms of alcohol in 100ml of breath. This has been reduced from 35 micrograms.
How long it takes for alcohol to leave the body
You should be aware that the morning after a night out when you were drinking alcohol you may still be over the new lower limit very easily the next day, particularly in the morning.
The new limits are only being introduced in Scotland. If you are in England and Wales and Northern Ireland the drink driving limits are still 80 micrograms in 100ml of blood. If you are within the alcohol limit for driving outside Scotland and cross the border into Scotland in your vehicle you may fail a breath test.
This may be particularly important to be aware of over the Christmas and New Year breaks as many people visit family and friends all over the UK. Remember that drinking the night before can mean you are over the limit the next day because it takes some time for alcohol to leave your system.
