Western Australia Child Car Seat Laws: Fines, Demerit Points and Exemptions

In Western Australia, a driver who lets one child ride without a suitable, properly fitted restraint faces a $550 modified penalty and 4 demerit points, doubling to 8 points during a gazetted holiday period.

Western Australia's Child Restraint Rule and Its New Driver-Liability Offence

Western Australia's child restraint requirements are set out in regulation 234 of the Road Traffic Code 2000 (WA), "Wearing of seatbelts by passengers under 16 years old." The duty to actually ensure compliance sits in a separate, newer provision: regulation 232A, "Driver responsible for passengers," which requires that the driver of a motor vehicle must ensure that each passenger in or on the vehicle complies with the requirements in regulation 233 or 234. Regulation 232A did not exist in this form until SL 2025/36 inserted it, gazetted 5 February 2025 and commencing 6 February 2025 for most of the instrument. The penalty and demerit-point figures for both regulation 232A and regulation 234 offences are set out in a third provision, regulation 235A, "Penalties for seatbelt offences by driver."

Age Bands: What the Law Requires

Western Australia's age and restraint-type bands under regulation 234 follow the same structure used nationally (see the Child car seat laws in Australia hub for the full national age-band table and the standards behind "approved"):

• Under 6 months: a rear-facing approved child restraint.
• 6 months to under 4 years: a rear-facing restraint, or a forward-facing restraint with an inbuilt harness. Children in this band must not sit in the front row of a vehicle with 2 or more rows of seats.
• 4 years to under 7 years: a forward-facing restraint with an inbuilt harness, or an approved booster seat with a correctly fastened lap-and-sash seatbelt or safety harness. The front-row restriction generally continues to apply.
• 7 years to under 16 years: either an approved child restraint or a correctly adjusted and fastened seatbelt.

The Fine: $550 for One Child, More for Multiple

Regulation 235A's penalty table is set in penalty units, not flat dollars - Western Australia's standard rate is $50 per penalty unit under the Road Traffic (Administration) Act 2008. For a driver who is wearing their own seatbelt correctly but has at least one unrestrained child passenger under 16, the modified penalty is:

• 1 unrestrained passenger: 11 penalty units, $550.
• 2 unrestrained passengers: 12 penalty units, $600.
• 3 unrestrained passengers: 14 penalty units, $700.
• 4 or more unrestrained passengers: 16 penalty units, $800.

If the driver is also not wearing their own seatbelt, the combined offence carries a higher schedule of 12, 14, 16 and 18 penalty units for the same passenger counts. These are the modified, on-the-spot infringement penalties a driver actually receives; Western Australia's regulation does not print a separate court-maximum figure for this offence the way some other states' road rules do.

Demerit Points and Holiday-Period Doubling

Each unrestrained-passenger tier in regulation 235A's table carries 4 demerit points outside a holiday period, doubling to 8 demerit points during a gazetted holiday period - Western Australia's standard gazetted holiday periods (WA Police and the Department of Transport publish the exact dates each year, typically covering major long weekends and holiday seasons) double-demerit windows. This doubling applies to the demerit points only. The modified penalty dollar amount, $550, $600, $700 or $800, does not change during a holiday period; only the points attached to the offence double.

Taxi and Rideshare Exemptions

Regulation 234(13) exempts the driver of a "passenger transport vehicle" from the child restraint requirement if no suitable child restraint is available in the vehicle and the child is not seated in the front row of a vehicle with 2 or more rows of seats. Passenger transport vehicle is defined by cross-reference to the Transport (Road Passenger Services) Act 2018 (WA), which splits on-demand passenger transport service into on-demand rank or hail, the traditional taxi model, and on-demand charter passenger transport service, which covers booked, non-hail services such as Uber, Ola and DiDi. Both categories fall under the same passenger transport vehicle definition, so the exemption applies identically to a taxi and a rideshare vehicle under current WA law.

Who Is Liable, and Where to Get Your Child's Seat Fitted

Regulation 232A places the legal duty on the driver of the vehicle, not the child's parent specifically - a grandparent, rideshare driver or family friend behind the wheel carries the same responsibility a parent would. A narrow defence applies only if the passenger has reached 16 and the vehicle was a passenger transport vehicle; it does not cover a child restraint breach. For fitting help, the WA Road Safety Commission directs drivers to their local WALGA RoadWise Committee for a list of Type 1 Child Car Restraint Fitters, and to the Department of Transport for Type 2 Child Restraint Fitting Stations where anchor points can be safely installed. The current standard is AS/NZS 1754, with a separate AS/NZS 4370 pathway available for children with a disability through Department of Transport approval.
