UK Drug Driving Penalty Calculator - Fines, Bans & Legal Limits
This UK drug driving penalty calculator helps you understand the possible penalties you may face if you are found over the legal drug driving limits. It is designed for educational purposes and follows current UK drug driving laws.
The calculator can give guidance on potential driving bans, fines, and legal outcomes, but it does not provide legal advice and cannot confirm guilt or innocence.
How the Drug Driving Penalty Calculator Works
This tool is simple to use. You select the drug involved and review the guidance based on UK legal limits. The calculator then shows the possible penalties that may apply if a driver is found over the legal threshold.
The results are estimates only. Actual penalties depend on many factors, including police evidence, blood test results, and court decisions.
UK Drug Driving Legal Blood Limits
In the UK, drug driving laws are enforced under Section 5A of the Road Traffic Act 1988. Each drug has a specific legal blood limit. Exceeding these limits can result in prosecution, even if impairment is not obvious.
| Drug | Legal Blood Limit (UK) |
|---|---|
| Cannabis (THC) | 2 micrograms per litre (µg/L) |
| Cocaine | 10 micrograms per litre (µg/L) |
| Benzoylecgonine | 50 micrograms per litre (µg/L) |
| MDMA (Ecstasy) | 10 micrograms per litre (µg/L) |
| Amphetamine | 250 micrograms per litre (µg/L) |
These limits apply in England and Wales. Scotland and Northern Ireland have similar laws but may follow different legal procedures.
Drug Driving Penalties in the UK
If a driver is found over the legal drug driving limit, the court may issue serious penalties. These penalties apply even for first-time offences.
Typical UK drug driving penalties include a minimum 12-month driving ban, an unlimited fine, and up to 6 months in prison. A drug driving conviction stays on your driving record for 11 years.
Repeat offences or aggravated cases can result in longer bans, higher fines, and increased legal consequences.
Prescription Drugs and Drug Driving
Some prescription medicines can also lead to drug driving charges. Having a prescription does not always protect a driver from prosecution.
Drivers must follow medical advice carefully and ensure their medication does not impair driving ability. If blood levels exceed legal limits or driving ability is affected, penalties may still apply.
What This Calculator Can and Cannot Tell You
This calculator provides general guidance only. It cannot determine whether you will be charged, convicted, or banned from driving.
Every case is different. Police procedures, laboratory testing, and legal representation all affect the final outcome. Always seek professional legal advice if you are facing drug driving charges.
