PAB theory tests and road-riding certificates in Singapore

PAB riders need a competency test before road use, with a separate road-only certificate route. This guide explains rider and device requirements, registration, and ownership transfer.

Check the PAB and rider requirements

LTA says a PAB must be type-approved, sealed and registered before use on a road or cycling path; only models that meet the technical requirements can be registered. LTA lists an EN15194 compliance requirement, a maximum continuous output of 250 watts, motor assistance that starts only when pedalling and cuts out by 25 km/h (or earlier when pedalling stops), and a maximum weight of 20 kg. Riders and registrants must be at least 16. Check the current approved-model list and requirements before buying or riding (LTA, Power-Assisted Bicycle (PAB); LTA, Rules & Code of Conduct).

PAB riders need a theory-test certificate

LTA requires PAB riders to pass the mandatory PAB theory test before riding on cycling paths or roads. The test covers active-mobility rules, the code of conduct and safe riding practices; the statutory test syllabus includes law and safe riding practices on both public paths and roads. Holding a motor-vehicle driving licence does not replace this PAB test (LTA, Rules & Code of Conduct; Active Mobility (Competency Tests) Regulations 2021, rr. 3–5).

The Active Mobility Act competency-test provisions apply to prescribed classes of test-needed-to-drive vehicles. For PABs, the prescribed class is not banned for use on a shared path, meets the specified PAB road-approval requirements, and may lawfully be kept or used on a road. A person who rides a covered vehicle on a public path without the required certificate commits an offence, subject to statutory exclusions and exemptions. The Act excludes an under-aged rider from this certificate offence, but that exclusion does not itself permit riding a PAB: LTA says PAB riders under 16 must not ride on cycling paths or roads. The certificate lasts for the period stated on it or, if none is stated, the rider’s natural life, subject to cancellation. The maximum penalty for riding without a required certificate is a $2,000 fine or 6 months’ imprisonment, or both; for a repeat offender it is a $5,000 fine or 12 months’ imprisonment, or both (Active Mobility Act 2017, ss. 23D and 23F–23G; Active Mobility (Competency Tests) Regulations 2021, rr. 3–5; LTA, Rules & Code of Conduct).

LTA’s OneMotoring page says a registered PAB’s rear registration plate must be affixed within 3 calendar days of registration, at a conspicuous location with the characters facing rearward. LTA also says the seal must not be tampered with or removed. These are separate from the road-riding certificate requirements (LTA, Power-Assisted Bicycle (PAB)).

The Road Traffic Act’s road offence applies to both the prescribed PAB class covered by the path-test rules and the separate road-only PAB class. A rider in either class needs the corresponding competency-test certificate before riding on a road: the path-test-class certificate is granted under the Active Mobility Act, while the road-only PAB certificate is granted under the Road Traffic Act (Road Traffic Act 1961, s. 2; Road Traffic Act 1961, ss. 47G–47I; Active Mobility Act 2017, ss. 23D and 23F–23G).

Road-only PABs have a separate road-certificate route

The Road Traffic Act also covers a “road-only PAB”: a prescribed class of PAB that is not intended for use on any public path. The Land Transport and Related Matters Act 2026 added this definition to the Road Traffic Act; that amendment came into force on 4 May 2026. The current Road Traffic (Competency Tests) Rules prescribe a road-only PAB as one that meets specified PAB road-approval requirements, may lawfully be used on a road, and has either an unladen weight over 20 kg or a width over 70 cm. These are classification thresholds for this road-only category; they do not mean that every PAB over either threshold can be used on a road (Road Traffic Act 1961, s. 2; Land Transport and Related Matters Act 2026, s. 51; Land Transport and Related Matters Act 2026 (Commencement) (No. 4) Notification 2026; Road Traffic (Competency Tests) Rules 2021, r. 3).

To receive a certificate for a road-only PAB, the rider must register with the designated test authority and pass the prescribed PAB Theory Test. The rider must be at least 16 when taking the test, and must apply for the certificate within the 7 working days after passing (the test cannot be more than 7 working days old when the application is made). Each registration carries one test sitting and a non-refundable $5.45 test fee. The prescribed test covers safe riding practices and law on public paths and roads (Road Traffic (Competency Tests) Rules 2021, rr. 4–8 and Schedule).

A road-only PAB certificate remains valid for the period stated on it, or for the rider’s natural life if no period is stated, subject to cancellation under the Act. Riding a covered vehicle on a road without the required certificate is an offence. The maximum penalty is a $2,000 fine or 6 months’ imprisonment, or both; for a repeat offender it is a $5,000 fine or 12 months’ imprisonment, or both (Road Traffic Act 1961, ss. 47G–47I).

The Act also makes it an offence to employ or intentionally or negligently allow an untested person to ride a covered vehicle on a road. The maximum penalty is a $20,000 fine or 2 years’ imprisonment, or both; for a second or subsequent conviction it is a $40,000 fine or 4 years’ imprisonment, or both (Road Traffic Act 1961, s. 47K).

Ownership and modifications

When a registered PAB is sold or transferred, the current owner must initiate the online transfer within 7 calendar days of the physical handover; the next owner has 5 calendar days to confirm. LTA states the new owner must be at least 16 and the PAB must have a valid seal. Before buying, check that the PAB meets current technical requirements. LTA says modifications that make a PAB non-compliant with its tested EN15194 requirements are prohibited; it advises keeping the device in its tested, sealed and registered condition (LTA, Power-Assisted Bicycle (PAB)).

Coverage debt

The cited rules define vehicle classes but do not provide a practical lookup that tells a rider whether a particular model is a path-eligible PAB or a road-only PAB. LTA’s approved-model list and specifications help confirm approved models, but check with LTA if the applicable certificate route for a model remains unclear.
