Driving whilst under the influence of alcohol or drugs can impair your ability to drive safely, putting yourself and others in danger.
If you believe someone is currently driving under the influence of drink or drugs, call 999.
If you are caught drink or drug driving, you will be disqualified. You will also receive a minimum 12-month driving ban, a criminal record, and a fine of up to £5,000.
Each person responds differently to the amount of alcohol that it takes to reach the legal limit, there are several factors which can affect this, such as age, gender, metabolism, body type, what you have eaten, or even current stress levels.
The legally defined limits are:
You will be asked to provide a sample of breath at the road side.
If you fail this test, you will be arrested and taken to the police station where you will need to provide two further breath samples.
The lower of the two will then be used to decide if you are over the legal limit.
It is a criminal offence to refuse to provide a specimen of breath, blood or urine for the purposes of analysis.
