Australian Standards are the benchmark for WA traffic signs on private land, even where the law doesn’t strictly require them. Parking restrictions also need a legal enforcement route behind them. On industrial sites, signs that fall short of the standards become a safety and liability problem.
Most trouble starts at the buying stage, when a sign that looks right in a catalogue turns out to be unenforceable.
A regulatory sign is one that tells drivers what they must or mustn’t do. Stop, give way, speed limit and parking restriction signs all fall into this group. A warning sign only flags a hazard ahead, and the law treats the two differently.
Do Road Rules Apply on Private Property in WA?
Some road rules can apply on private property in WA, depending mostly on whether the area is open to or used by the public. Parking enforcement doesn’t carry over automatically, so a sign on its own gives nobody the power to issue fines.
- Shopping centre car parks are open to the public, so road rules may cover driver behaviour. Fining drivers for overstaying a time limit still needs a council agreement.
- Gated strata car parks have limited public access. Enforcement usually relies on strata by-laws or a council agreement, with towing as a fallback.
- Industrial sites run mostly on workplace safety duties. Visiting truck drivers still expect the signs to follow public road conventions.
Whether a particular car park counts as public depends on the facts of each site. Sites with restricted access are worth checking with a traffic engineer or lawyer before relying on road rules.
Which Standards Apply to WA Traffic Signs Off Public Roads?
The AS 1742 series of Australian Standards sets the benchmark for traffic signs, and AS 2890 covers car park design. Councils and insurers use them as the reference point on private land.
- AS 1742.11 covers parking controls, including how zones are signed and where they end.
- AS 1742.2 covers general traffic control devices like stop and give way signs.
- AS 1743 sets sign specifications such as shapes and letter sizes.
- AS/NZS 1906.1 covers retroreflective sign materials.
- AS 2890.1 deals with off-street car parks, and AS 2890.6 with off-street disability parking.
- Main Roads WA supplements add WA-specific signs, which is why some supplier catalogues carry “WA only” codes.
The standards become the yardstick whenever something goes wrong. A council officer assessing a parking agreement will check the signs against them, and so will a lawyer handling a collision claim.
When Can a Private Parking Restriction Actually Be Enforced?
A private parking restriction in WA is only enforceable with a legal mechanism behind it, usually a council agreement or a towing arrangement. Many WA councils, though not all, offer agreements that extend their parking local law onto private land. These agreements commonly fall over at the setup stage, for reasons like these:
- Signs go up before the agreement is signed.
- The sign wording hasn’t been approved by the council.
- The agreement number or local law reference is missing from the sign.
- The site relies on timed parking, which some councils won’t patrol.
- It’s a paid car park, which some councils won’t cover at all.
Once an agreement is signed and the approved signs are up, rangers can issue infringements. Unpaid fines escalate through the Fines Enforcement Registry. Setup usually involves a site inspection, and fees generally apply for setup and annual renewal.
A sign threatening penalties with nothing behind it is mostly theatre.
Wheel clamping is banned in WA. Since 14 December 2020, the Department of Transport has regulated towing from private property. Part 6A of the Road Traffic Act 1974 and the Road Traffic (Towing of Vehicles) Regulations 2020 set the rules.
A parked car generally can’t be towed unless the site’s signs meet Department of Transport requirements. Different rules can apply to a vehicle parked in a dangerous or obstructive position.
Sign requirements broadly depend on property type and bay numbers. Business sites with 50 or more bays sit in one group alongside commercial car parks. Smaller business sites and residential strata sit in another. Where a major sign is required, it must be at least 60 cm wide and 90 cm high.
A strata complex might screw “Residents Only, Unauthorised Vehicles Towed” plates to the bin enclosure, with no towing arrangement in place. When a stranger’s ute sits in a visitor bay for a week, the signs turn out to be legally decorative.
How Do ACROD Bays Work on Private Land?
ACROD bays on private land are usually enforced by the local council under an agreement with the owner. Councils can enforce the disability parking regulations in public places and in car parks they run. Many have been setting up agreements with private car park owners, including shopping centres and hospitals.
The bays need signs and markings that comply with the Road Traffic Code 2000. They also need to meet the Local Government (Parking for People with Disabilities) Regulations 2014. AS 2890.6 sets the bay design, including a 2.4 m wide space with an adjacent shared zone.
Owners can contract a private operator to monitor the bays instead, though that operator can’t issue council infringements. WA raised its ACROD penalties sharply in 2020, putting them among the toughest in Australia at the time. Common faults include a missing shared area or a sign hidden behind a parked van.
Where “Close Enough” Signage Goes Wrong
Most failures on private sites come from signs that break the conventions drivers already know from public roads. Any gap gives a driver room to argue they weren’t properly informed.
- Permissive parking signs with red lettering. Under AS 1742.11, green generally marks permissive parking like 2P, while red marks restrictions like No Stopping.
- Zone signs missing direction arrows or an end sign, so nobody can tell where a restriction stops.
- Vague custom wording such as “Short Stay Only” with no actual time limit.
- Stop signs used where give way would do. Drivers learn to roll through them, and the habit carries over to the intersections that matter.
- Sign sizes picked to fit a spare pole, with no thought for viewing distance.
Traffic engineers generally favour using Stop signs sparingly. A site covered in them teaches drivers to treat each one as optional.
Frequently Asked Questions
Can a Strata Company Fine Drivers for Parking in Visitor Bays?
A strata company can’t fine members of the public through a sign alone. It can enforce its by-laws against owners and occupiers, with penalties handled through the State Administrative Tribunal. Fining visitors generally needs a council parking agreement, and towing is a separate option with its own rules.
Do Signs in a Private Car Park Have to Meet Australian Standards?
Meeting Australian Standards is the safe default for private car park signs, even where the law doesn’t strictly require it. Councils often require compliance before approving a parking agreement, and some refer to AS 1743 directly. After a collision, non-standard WA traffic signs are one of the first things a claimant’s lawyer will look at.
Can Shopping Centres Still Clamp Cars in WA?
No, wheel clamping is banned in WA. Towing is still allowed, provided the property has a towing arrangement and compliant signs. Tow operators also have to follow set procedures before and after removing a vehicle.
Key Takeaways
Private property signs in WA hold up best when they follow Australian Standards, and parking restrictions also need an enforcement route. Signs bought without that groundwork tend to end up as expensive decoration.
- Sort out the council agreement or towing arrangement before ordering parking signs.
- Follow AS 1742.11 conventions for parking zones.
- Specify Class 1 film or better for anything that needs to be read at night.
- Treat ACROD bays as a separate compliance job.
- Photograph and inspect signs regularly, since faded signs are hard to defend.
