Police roadside powers under the Road Traffic Act
Stopping vehicles and arresting drivers
A police officer in uniform may stop a motor vehicle if its driver has committed, or is suspected of having committed, an offence under the Road Traffic Act or its rules. A driver must stop when required by a uniformed officer; failing to do so is an offence (Singapore Statutes Online, Road Traffic Act 1961, s. 127(4)–(5)).
A uniformed police officer may arrest without warrant a person in charge of or driving a motor vehicle who has committed, or is suspected of having committed, such an offence. The Act limits this arrest power: it must not be used if the person produces a driving licence that enables the officer to ascertain the specified particulars, or, for a person who is not within the listed paid-driver/passenger-for-hire-or-reward/goods-driver categories, gives their name and Singapore address. If the officer has reason to suspect that an ascertained or given name or address is false, the arrest power may still be exercised (Singapore Statutes Online, Road Traffic Act 1961, s. 127(6)–(8)).
Other road users, bicycles and passengers
A uniformed police officer may stop and arrest, without warrant, a person other than the driver of a motor vehicle who commits an offence under the Act or its rules within the officer’s view. The person must not be arrested if they satisfy the officer as to their name and Singapore residence, and that they do not intend to abscond. A police officer may detain a bicycle or tricycle in respect of which an offence was committed within the officer’s view (Singapore Statutes Online, Road Traffic Act 1961, s. 127(1)–(3)).
For examining a vehicle licence, the Registrar or a person authorised by the Registrar in writing (who produces that authority), or any police officer, may stop a vehicle other than a motor vehicle; a uniformed police officer may stop a motor vehicle. A driver must stop when required under this power, and failure to do so is an offence (Singapore Statutes Online, Road Traffic Act 1961, s. 127(9)–(10)).
When exercising the motor-vehicle stop, arrest or licence-examination powers in section 127(4), (6) or (9), a uniformed police officer may require a person who appears to be or to have been a passenger in the vehicle to give their name and address. If the passenger refuses, the officer may arrest them to ascertain those particulars. Unless they are ascertained sooner (in which case the person must be released immediately on executing a bond, with or without sureties, for court appearance if required), the person must be taken before a Magistrate’s Court within 24 hours of arrest. The Court is to require a bond, with or without surety, for appearance if required (Singapore Statutes Online, Road Traffic Act 1961, s. 127(11)–(13)).
Identity evidence for prescribed offences
For an offence prescribed under section 127A, the Registrar or a written-authorised officer of the Land Transport Authority may require the person who commits it in the officer’s view to furnish identity evidence. Refusing, or wilfully giving false information, is an offence punishable on conviction by a fine of up to $500. Refusal or reason to believe supplied information is false permits a warrantless arrest; a person arrested under this power may not be detained longer than necessary to bring them before a court unless a court orders detention (Singapore Statutes Online, Road Traffic Act 1961, s. 127A(1)–(5)).
The prescribed-offence rules identify an offence under section 131(1)(c) read with Road Traffic Rules rule 26C(1). Rule 26C(1) concerns unauthorised presence in specified bus-terminus or bus-interchange bus areas that are not demarcated for pedestrian access. The Act’s former section 127B offences are also named in the rules, but sections 127B and 127C were deleted with effect from 23 September 2026 (Singapore Statutes Online, Road Traffic (Prescribed Offence under section 127A) Rules, r. 2; Singapore Statutes Online, Road Traffic Rules, r. 26C(1); Singapore Statutes Online, Road Traffic Act 1961, ss. 127B–127C).
When an officer is not in uniform
When acting against a person under the Act, a police officer who is not in uniform must, on demand, declare their office and produce the identification card directed by the Commissioner of Police to be carried. It is not an offence for a person to refuse a request, demand or order made by an officer who fails to do both on demand (Singapore Statutes Online, Road Traffic Act 1961, s. 128).
Coverage debt
The prescribed-offence rules still refer to offences under former section 127B(6), although section 127B was deleted with effect from 23 September 2026. The current effect, if any, of that surviving reference is not explained in the cited legislation. This article therefore records the rule’s explicit section 131(1)(c) and rule 26C(1) reference without inferring any additional offence. The section 127A extract also does not state whether another prescribed-offence instrument has since been made.
This article describes only the cited Road Traffic Act provisions; it does not establish whether other laws confer additional roadside powers.
