What Is Drug Driving?
Drug driving in the UK refers to operating a vehicle with a prohibited drug in your bloodstream at or above the legal limit, or being impaired by drugs while driving.
- Illegal drugs: Substances such as cannabis, cocaine, ecstasy, or heroin.
- Prescription or over-the-counter medication: If it impairs your ability to drive, you can still be prosecuted.
Police have strict measures to detect drug driving, including roadside saliva tests and blood tests in more serious cases.
Immediate Consequences of Being Caught
If caught, you may face:
- Arrest at the scene
- Driving ban (minimum 12 months for first offences)
- Unlimited fines
- Criminal record and possible imprisonment
- Impact on insurance premiums
Even being under the influence of prescribed medication can lead to prosecution if it affects your driving.
