Chalking tires is illegal in four states and legal almost everywhere else. A 2019 federal appeals court ruling made the practice unconstitutional in Kentucky, Michigan, Ohio, and Tennessee, holding that a parking officer touching your tire to mark it counts as a Fourth Amendment search. A different appeals court looked at the same question in 2022 and reached the opposite conclusion for the nine western states it covers. The Supreme Court declined to resolve the disagreement, so whether chalking tires is illegal depends entirely on where your car is parked.
The Four States Where Chalking Is Unconstitutional
The Sixth Circuit Court of Appeals covers Kentucky, Michigan, Ohio, and Tennessee.1United States Court of Appeals for the Sixth Circuit. About the Court In 2019, that court decided Taylor v. City of Saginaw, a case brought by a Michigan driver who had received fifteen chalk-based parking tickets over three years. The court ruled that placing chalk on a tire is a physical intrusion onto private property for the purpose of gathering information, which makes it a search under the Fourth Amendment.2Justia. Taylor v. Saginaw, No. 17-2126 (6th Cir. 2019)
Saginaw argued the practice fit the “community caretaking” exception that lets officers act without a warrant to protect public safety. The court rejected that reasoning. Parking enforcement is about managing street space and collecting revenue, not responding to safety emergencies, so no warrant exception applied.3UNITED STATES COURT OF APPEALS FOR THE SIXTH CIRCUIT. Taylor v. City of Saginaw
Saginaw stopped chalking in 2019. Ann Arbor and other cities in the four-state region did the same. If you live in the Sixth Circuit and a municipal officer still chalks your tire, the practice is unconstitutional under binding federal law.
The Nine States Where Chalking Is Legal
The Ninth Circuit Court of Appeals, which covers California, Oregon, Washington, Arizona, Nevada, Idaho, Montana, Alaska, and Hawaii, considered the same question in Verdun v. City of San Diego in 2022. It reached the opposite result. Even assuming chalking is a search, the court said, it fits comfortably within the administrative-search exception.4United States Court of Appeals for the Ninth Circuit. Verdun v. City of San Diego
The Ninth Circuit weighed the public interest in keeping traffic flowing and parking spaces turning over against the intrusion of a chalk dust mark on a tire. It called the intrusion “infinitesimal” and found that chalking is narrowly tied to parking enforcement, with no spillover into general crime control. The court explicitly disagreed with the Sixth Circuit.
Everywhere Else: Unsettled
Outside those two circuits, no binding federal ruling exists either way. The Taylor decision carries persuasive weight, which means courts in other states can look to its reasoning but are not required to follow it. Some municipalities have voluntarily dropped chalking to avoid lawsuits. Many others continue the practice without challenge. Whether your city still chalks and whether a local court would strike it down are open questions in most of the country.
Private Lots Don’t Count
The Fourth Amendment restrains the government, not private businesses. If a shopping mall, apartment complex, or private garage marks your tire to enforce its own time limits, no constitutional issue arises. The Taylor rule only reaches a government employee doing the marking.
Why the Supreme Court Hasn’t Fixed the Split
The San Diego plaintiffs asked the Supreme Court to resolve the conflict, pointing out the obvious problem: the same enforcement tactic cannot be a constitutional search in one half of the country and an unconstitutional one in the other.5Supreme Court of the United States. Reply Brief for the Petitioners in Verdun v. City of San Diego (No. 22-943) In October 2023, the Supreme Court denied review.6Supreme Court of the United States. Docket for 22-943 Until the Court takes up another case on the issue, the geographic split is the law.
If You Already Got a Chalked Ticket
You probably cannot get your money back. Even in the Sixth Circuit, where the practice was declared unconstitutional, the district court on remand refused to order refunds of fines already paid. The affected class received only nominal damages for each instance of chalking.7Justia. Taylor v. City of Saginaw et al, No. 1:2017cv11067 The parking officer who did the chalking received qualified immunity because the law was not clearly established when she acted.
Outside the Sixth Circuit, the practice remains presumptively legal, so a constitutional challenge to a past ticket faces an even steeper climb. Contesting a paid ticket after the appeal window has closed is difficult in any jurisdiction. The practical result of Taylor is that it changed enforcement going forward, not that it created a path to refunds.
What’s Replacing Chalking
Many cities have moved to enforcement methods that don’t involve touching the car. The most common is license plate recognition. Cameras on patrol vehicles or fixed poles scan plates and record each one with a timestamp and location. When the system sees the same plate in the same block past the time limit, it flags the car for a citation. No chalk, no physical contact, no Fourth Amendment problem on the Taylor theory.
License plate recognition has its own legal issues. The systems collect data on every vehicle they scan, not just violators, and some agencies keep the records for years. Challenges to warrantless use of these databases are moving through the courts, with at least one case before the Eleventh Circuit.
Pay-by-phone apps and digital meters are the other main alternative. The driver starts and ends a session through an app or kiosk, and officers check whether a plate has an active session instead of marking the tire. Because the driver participates voluntarily, these systems avoid the intrusion question entirely.
