SingaporeWhat is the penalty for driving under drug influence?
Driving under the influence of drugs in Singapore is punishable by up to 10 years’ imprisonment, a fine of up to $20,000, and mandatory disqualification from driving for at least 2 years.
What the Law Says
The Road Traffic Act makes it a criminal offence to drive or attempt to drive a motor vehicle while under the influence of drugs to such an extent that you are incapable of having proper control of the vehicle.
This offence applies whether the drug is illegal, prescription-based, or over-the-counter — what matters is its impairing effect on your ability to drive safely.
The law treats drug-impaired driving as seriously as alcohol-impaired driving, with strict penalties designed to deter dangerous behaviour and protect public safety.
Conviction triggers automatic disqualification from holding or obtaining a driving licence, and courts have no discretion to waive this requirement.
Statutory TextAny person who, when driving or attempting to drive a motor vehicle on a road, is under the influence of a drug to such an extent as to be incapable of having proper control of the vehicle shall be guilty of an offence.
— Road Traffic Act, s. 67 — Driving under influence of drug
What to Do
Stop driving immediately if you have taken any drug that may impair alertness, coordination, or reaction time.
Consult your doctor or pharmacist about the driving risks of prescribed or over-the-counter medications.
If charged, seek legal advice promptly — penalties are severe and disqualification is mandatory.
Cooperate fully with police testing (e.g., urine or oral fluid screening) as refusal may lead to separate charges.
