Drink and Drug Driving

Driving whilst under the influence of alcohol or drugs can impair your ability to drive safely, putting yourself and others in danger.

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 £5000.

What are the legal alcohol limits?

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:

  • 35 micrograms of alcohol in a 100 millilitres of breath
  • 80 milligrams of alcohol in a 100 millilitres of blood
  • 107 milligrams of alcohol in a 100 millilitres of urine

What is a breath test?

If you are stopped by the police and suspected of drunk driving, 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.

Please note: It is a criminal offence to refuse to provide a specimen of breath, blood or urine for the purposes of analysis.

How is drug driving tested?

Officers can assess whether the driver may have taken drugs. One way this can be achieved is by making the suspect participate in a Preliminary Drug Test or through Drug Influence Recognition. These include a non-invasive eye examination, balance exercises, co-ordination exercises and divided attention exercises.
