What is this right?
Police and Traffic Police officers can stop vehicles and conduct checks under the Road Traffic Act:
- Power to stop: Any police officer in uniform may require a driver to stop the vehicle (Road Traffic Act, s26).
- Document checks: You must produce your driving licence, vehicle registration, and insurance when asked.
- Breathalyser tests: Police can require a breath test if they suspect you have been drinking, or at designated road blocks. Refusal is an offence.
- Road blocks: Under CPC s80, police may set up road blocks to stop and search vehicles during investigations.
- Drink-driving limit: 35 micrograms of alcohol per 100 millilitres of breath (or 80mg per 100ml of blood).
When does it apply?
- You are driving or in control of a vehicle on a public road in Singapore.
- Road blocks can apply to all vehicles — you do not need to be suspected of an offence.
What to Do If You Are Stopped at a Traffic Stop or Road Block by the Traffic Police in Singapore
- Pull over safely when signalled by a police officer.
- Have your documents ready — driving licence, vehicle registration card, and proof of insurance.
- If asked to take a breath test, comply — refusal is an offence carrying the same penalties as drink-driving.
- If arrested for drink-driving, a blood test may be taken at a hospital — you may request an independent blood test at your own expense.
What should you NOT do?
- Don't refuse a breathalyser test — refusal carries a fine of up to $10,000 and/or imprisonment up to 12 months, plus mandatory driving ban.
- Don't drive away from a road block — this is an offence and may result in a chase and additional charges.
- Don't argue at the roadside — if you believe the stop was unlawful, comply and challenge it later through legal channels.
