What are the legal alcohol limits for driving?

 

Current legal limits are:

• Drivers under 20 years - 0mg per 100mls blood.  No alcohol allowed at all. 
• Drivers over 20 years - 400mcg per litre of breath or 80mg per 100mls blood.

A lot of people find it extremely difficult to work out if they are staying within these legal limits as each person has a different alcohol tolerance and metabolism. The safest option is to not drive at all if you have been drinking alcohol.
