How parking enforcement works

What does chalk on your tyre mean?.

Updated 29 April 2026 7 min read By The Chalked Team

That smudge of chalk on your tyre is a parking inspector's timer. Here's how chalking works in Australia, whether it's still in use, and what happens if you wipe it off.

You walk back to your car, glance down, and there’s a chalk mark on the side of your tyre. Don’t panic. It’s not graffiti, not vandalism, and not necessarily a fine. It’s a parking inspector’s timer — and understanding how it works tells you a lot about how parking enforcement actually operates in Australia.

This guide covers what the chalk means, whether the practice is still in use, the legal grey area around removing it, and what’s quietly replacing it across most Australian capital cities.

What chalk on a tyre actually means

A parking inspector chalks your tyre to start a clock. They draw a small mark — usually a line, arrow, or letter — on the part of the tyre that touches the road, and note the time. If they walk past again later and the mark is still in roughly the same position, it means the car hasn’t moved. If you’ve parked in a 1-hour zone and they come back 70 minutes later to find the chalk untouched, the timer is up and they can issue a fine.

That’s it. The chalk doesn’t prove an offence on its own. It’s just a way to confirm one specific thing: that the same vehicle has been in the same spot for too long.

The technique has been used by parking inspectors in Australia, the UK, and the US for decades. It’s not high-tech, but it’s reliable, requires no equipment beyond a stick of chalk, and works in any weather, any street, any time of day.

What the chalk looks like

If you’re checking your tyres, look for:

It’s almost always on the inside (kerb-side) of the tyre, where it’s harder to spot from the driver’s seat and harder for the elements to wipe off too quickly.

Is chalking still happening in 2026?

Yes — but less than it used to. Many Australian councils have shifted to licence plate recognition (LPR) cameras mounted on patrol vehicles. The car drives down a street, the camera reads each number plate, and the system flags any plate that’s been in the same spot for too long when the patrol returns later. Canberra began trialling this technology back in 2017, and councils across NSW, Victoria, and Queensland have since rolled out their own LPR systems.

But chalk hasn’t disappeared. It’s still in use because:

If you’re parked on a major arterial road in central Sydney, you’re more likely to be caught by LPR. If you’re in a side street in Marrickville, Coogee, or Manly, chalk is still very much in play.

This is where it gets interesting, and it’s not the same answer everywhere in Australia.

South Australia — explicitly illegal

South Australia is the only state with a specific law on this. Section 174AB of the Road Traffic Act 1961 (SA) makes it an offence to remove or interfere with a parking inspector’s chalk mark. The maximum penalty is $750, and there have been recent enforcement actions where the threat has been publicly raised.

NSW, Victoria, Queensland — general perverting offences

In NSW, there’s no parking-specific provision, but Section 319 of the Crimes Act 1900 (NSW) creates a general offence of “perverting the course of justice” with a maximum penalty of 14 years’ imprisonment. In theory, deliberately wiping a chalk mark to dodge a fine could fall under this. In practice, no one is going to jail for it.

The reason: prosecution requires proof beyond reasonable doubt that you specifically intended to interfere with the enforcement process. Unless an inspector saw you do it, or there’s CCTV, that bar is essentially impossible to clear. The provision exists, but it’s not used for parking-chalk wipers.

Victoria has a common law equivalent (perverting the course of justice, technically up to 25 years in extreme cases), and Queensland has Section 140 of the Criminal Code 1899 (Qld). Same principle, same practical reality — these aren’t being used to chase chalk-wipers.

What this means in practice

Don’t go around wiping chalk off other people’s tyres for fun — that’s a separate problem. But on your own car? In every state except SA, the legal risk of removing a single chalk mark is essentially zero, even if the technical legal position is “you probably shouldn’t.”

A more reliable strategy: just move your car. Move it before the time limit is up. That’s not illegal anywhere.

The “around the block” trick

The most common trick people try is moving the car a short distance so the chalk mark is in a different position on the tyre, hoping the inspector will think it’s a different car or a fresh park.

This used to work occasionally. It’s much less reliable now because:

If you genuinely need to stay longer than the limit, the safest move is to leave the area entirely (drive at least a few blocks, not just down the street) or — better — find a park where the limit fits your needs.

What you should actually do if you see chalk

Practically speaking:

  1. Note the time. If you can, work out roughly when the chalk was put on by checking when you parked.
  2. Check the sign. Make sure you understand the actual time limit. People assume “1P” means an hour but miss the small print about days or hours of effect.
  3. Move within the limit. If you’re going to overstay, don’t try to wipe the chalk — just leave and find another park.
  4. If you got a fine, check whether the inspector took proper photos showing the chalk position before and after. As of 1 July 2025, NSW parking officers must photograph the offence and notification, which means there’s an audit trail you can reference if you appeal.

A note on the app

Yes, this is a Chalked guide on Chalked. The reason the app exists is that chalk-and-LPR enforcement gives you no warning until you walk back to a fine — by which point it’s too late. Chalked is crowdsourced reports from drivers and pedestrians who’ve spotted parking officers on the move, so you can get back to your car before the timer runs out. If you read this far, it’s free on the App Store.

Frequently asked.

Is it illegal to wipe chalk off your tyre in Australia?

It depends on the state. South Australia has a specific law making it an offence to remove an inspector's chalk mark (up to $750). In other states, including NSW, there's no specific law — but it could fall under general "perverting the course of justice" provisions. In practice, prosecutions are extremely rare because intent is hard to prove.

Why do parking inspectors still use chalk?

It's cheap, instant, and works without electronics. Many councils now use licence plate recognition (LPR) cameras instead, but chalk is still used on foot patrols, in side streets, and as a backup. The Australian Capital Territory began trialling LPR in 2017 but kept chalk for areas the cameras can't cover.

Can I just move my car a few metres to dodge a chalk mark?

Not reliably. Modern enforcement combines chalk with photos, and LPR systems track your number plate, not your tyre. Moving the car the same length around the block is the well-known trick — and the well-known thing inspectors are watching for.

How long does parking chalk last?

It's basic blackboard chalk and washes off in light rain or after a few hundred metres of driving. It's only intended to last for the inspector's return visit, usually within a few hours.

Is chalk on my tyre proof I'll get a fine?

No. Chalk just means an inspector started a timer. If you leave before the time limit is up — or move your car far enough that they can't argue you stayed — there's no fine. The chalk on its own isn't evidence of an offence.

What if I get chalk on me from the tyre?

It's harmless. Standard non-toxic chalk, comes off skin and clothes with water. The mark on the tyre is small — usually just a line or arrow about 5–10 cm long, low down where it touches the road.
