6.3 Child Restraints: The Taxi Exemption vs Private Hire Cars

Child-restraint rules are one of the easiest areas to get wrong on the TDVL safety domain, precisely because the rule is not the same for every point-to-point vehicle. This section sets out Singapore's general child-restraint law, the specific exemption that applies to licensed taxis, and the very different rule that applies to private hire cars — an asymmetry that shows up repeatedly in TDVL scenario questions.

Under Singapore's Road Traffic (Motor Vehicles, Wearing of Seat Belts) Rules, every child under 1.35 metres in height must be secured in an approved child restraint appropriate to their age, height, and weight when travelling in an ordinary vehicle. This is the default rule TDVL candidates must know before learning the taxi-specific exemption below.

The Taxi Exemption

Licensed taxis are exempt from the requirement to carry child restraints. The rationale is practical: a taxi accepts on-demand street hails and bookings from a constantly changing set of passengers, so it is not feasible for a taxi to stock a full range of child-seat sizes — infant, convertible, booster — the way a private car owner would for their own child.

Under this taxi exemption:

• A child under 1.35m should ride in the rear seat of the taxi and wear the adult seat belt, where one is fitted.
• If that child instead rides in the taxi's front passenger seat, they need their own child restraint or booster seat to supplement the seat belt — the rear-seat allowance does not carry over unchanged to the front seat.

Private Hire Cars: No Exemption

Private hire cars (PHCs) — including vehicles booked through Grab, Gojek, TADA, Ryde, and GoCar — are not exempt. The full child-restraint rule applies every time a child under 1.35m travels in a PHC: an approved child restraint or booster seat appropriate to the child is required, and the PHC must be able to provide one for such passengers. This is the single most commonly tested TDVL-versus-PDVL distinction in the safety domain, because the two vehicle types can look almost identical from the roadside yet are governed by different child-restraint rules.

Taxi vs PHC: Side-by-Side Comparison

Why This Matters on the Exam

Because a taxi and a PHC can be the exact same body style of car, TDVL candidates cannot rely on how the vehicle looks — the rule follows the licence type, not the vehicle's appearance. A driver moving between TDVL and PDVL work, or a passenger comparing a taxi ride to a private-hire ride, needs to know that the child-restraint obligation changes even when nothing else about the trip does.

Practical Guidance for TDVL Holders

• The 1.35m threshold is about height, not age — a small nine-year-old is still covered by the rule, while a tall five-year-old who has already reached 1.35m is not.
• Because taxis are exempt, a TDVL holder is not legally required to carry or offer a child seat — but nothing prevents a driver from voluntarily doing so, and some app-based taxi bookings let a passenger flag a child-seat request in advance.
• The safe default when a young child boards a taxi is: child in the rear seat, adult seat belt fastened so it fits properly across the child's body rather than across the neck.
• If a family specifically asks to seat the child in front, remind them that the front seat needs its own child restraint or booster under the exemption, and that a taxi may not have one available — so the rear seat is usually the more practical, readily-compliant choice.

If a Passenger Disagrees

Occasionally a parent may insist a young child sit in the front seat without any restraint, believing the taxi exemption removes all requirements. A professional driver should politely clarify that the exemption's seat-belt-only allowance applies specifically to the rear seat, and that a front-seated child under 1.35m still needs a restraint or booster to supplement the seat belt — recommending the rear seat instead if no restraint is available, since it is the more readily compliant option for a taxi.

Penalties for Non-Compliance (Non-Exempt Vehicles)

For vehicles where the child-restraint rule does apply — private cars, PHCs, and any other non-exempt vehicle — failing to secure a child under 1.35m in an approved restraint is an offence. Lighter cases can be dealt with as a composition fine of $150 plus 3 demerit points; more serious non-compliance can carry penalties of up to $1,000 or 3 months' imprisonment. None of this changes the taxi exemption itself — it simply explains why the underlying rule matters so much in the vehicles where it is not exempted.
