IrelandWhat are the penalties for drug driving?
In Ireland, drug driving is a criminal offence under the Road Traffic Act 2010. Penalties include a mandatory disqualification from driving for at least 1 year, a fine of up to €5,000, and/or up to 6 months’ imprisonment.
What the Law Says
The Road Traffic Act 2010 makes it illegal to drive or attempt to drive while impaired by a controlled drug — even if the driver feels fit to drive. The law applies whether the drug was taken legally (e.g., prescribed medication) or illegally.
Section 4 of the Road Traffic Act 2010 creates the offence of driving or being in charge of a vehicle while impaired by a controlled drug. It does not require proof that the driver intended to be impaired — only that impairment existed and affected their ability to drive safely.
The law covers all controlled drugs listed in the Misuse of Drugs Acts, including cannabis, cocaine, heroin, benzodiazepines, and some prescription medications like morphine or diazepam — especially when taken in amounts that impair driving ability.
A person convicted on summary conviction (in the District Court) faces a fine of up to €5,000, up to 6 months’ imprisonment, and mandatory disqualification from driving for at least 1 year. On indictment (in the Circuit Court), penalties are more severe and may include longer disqualification and higher fines.
Statutory TextA person shall not drive a mechanically propelled vehicle or attempt to drive such a vehicle on a road while under the influence of a controlled drug to such an extent as to be incapable of having proper control of the vehicle.

What to Do
If stopped by Gardaí and suspected of drug driving, you must provide a sample (oral fluid, blood, or urine) when lawfully requested.
Seek legal advice immediately — convictions carry serious consequences for insurance, employment, and travel.
Do not drive if taking any medication known to cause drowsiness, dizziness, or slowed reaction times — check packaging or consult your doctor/pharmacist.
If disqualified, you must wait the full period before reapplying for a licence — early reinstatement is not permitted.
