A bipartisan bill package would change that.
State Reps. Jimmie Wilson Jr., D-Ypsilanti, and Doug Wozniak, R-Shelby Township, have introduced a two-bill plan intended to regulate the use of automatic license plate readers, ALPRs, by private companies and government entities.
The bills would create clear limits on how data is collected, stored and shared, Wilson said, ensuring the tools are “used to improve public safety, not to enable routine mass surveillance.”
License plate readers are small mobile or mounted surveillance cameras that capture vehicle license places as they pass by, sometimes snapping photos of as many as hundreds of plates per minute.
In addition to license plates, the cameras capture other vehicle information, such as make and model.
They have been primarily used by local law enforcement agencies. According to a July 2025 report by Congress, 100% of police departments serving over a million residents used ALPRs, along with nearly 90% of sheriff’s offices with 500 or more sworn deputies.
More than 125 cities and counties across the state now use the cameras in some form, according to data reported by Bridge Michigan.
The state of Michigan now has a $2.626 million contract with Flock Safety valid through June 2030.
In the last few years, communities across the state — like Kentwood, Kalamazoo, Flint, Portage, Wixomand several townships surrounding Traverse City— have also signed or renewed license plate reader contracts, though not all with Flock.
Police have credited the automatic systems for playing a role in solving homicides and violent assaults, recovering stolen vehicles and property and finding missing children.
But Flock Safety, which is used by most Michigan law enforcement agencies, has also come under scrutiny in recent months for potential use by federal Immigration and Customs Enforcement.
Independent media company 404 Media found in May 2025 that local police around the country are performing lookups in Flock’s ALPR system for immigration related searches, giving federal law enforcement unofficial access to a tool without a formal contract.
A Jan. 6 statement from Flock said it “does not work with U.S. Immigration and Customs Enforcement (ICE) or any other sub-agency of the Department of Homeland Security,” and added that ICE does not have direct access to its cameras, systems or data.
But in the months since, communities have faced pushback when the time comes to renew contracts.
In November of last year, local leaders in Bay City rejected a two-year contract with Flock following public privacy worries.
American Civil Liberties Union of Michigan policy strategist Gabrielle Dresner, who testified in Bay City ahead of the decision, said she was concerned about the lack of existing state regulations.
Last month, Genesee County also postponed decisions on whether to renew contracts for its 30 Flock Safety cameras because of the same concerns.
Commissioner Shaun Shumaker, R-Fenton Twp., said the technology “helps (law enforcement), but guess what? If they’re taking that data and selling it overseas and selling it to other agencies and organizations, we need to know.”
And Kalamazoo residents have called on the city’s department of public safety to stop using the cameras from Flock Safety, claiming they are a violation of residents’ Fourth Amendment rights.
In a press release shared last month, bill sponsors Wozniak and Wilson said information amassed by the plate readers can be used to track individuals, including what doctors, protests, meetings or religious institutions a person visits.
Without clear limits on acceptable use, those systems risk shifting from targeted investigative tools into “broad, ongoing tracking systems that monitor everyday people who are not suspected of wrongdoing,” they wrote.
“Michiganders deserve to know that new technology is being used responsibly, not in ways that invade privacy or erode public confidence,” Wozniak said. “These bills protect the privacy of Michigan motorists while setting clear, commonsense rules that help maintain trust between law enforcement and the public.”
The bill package would define what automatic license plate readers systems are. Wilson’s House Bill 5493 would clarify that government entities could use automatic readers systems only to:
- Compare captured plate data with alert data to identify uninsured, unregistered or stolen vehicles, along with vehicles registered to someone who has an outstanding arrest warrant, is associated with a missing individual or is relevant to an ongoing criminal investigation
- Regulate the use of parking facilities by parking enforcement entities
- Control access to secured areas
- Collect electronic tolls
The bill package also requires government entities that use automatic license plate readers to adopt and post policies on their use.
They would be required to submit a quarterly report on practices and usage to the state or local government that oversees them, including the number of license plates scanned and the number of data matches that resulted in an arrest.
Wozniak’s House Bill 5492 would then regulate the use of ALPR systems by private companies, requiring them to preserve captured plate data for “not less than 14 days” after a preservation request is received by a government entity or defendant in a criminal case.
Data must otherwise be destroyed 14 days after a request is received or if the application is denied, whichever is later.
Violators can be sued for damages or $1,000, whichever is greater, along with attorney fees.
The bill would also mandate that data held by private companies not be disclosed under the Freedom of Information Act, and would be otherwise disclosed only to the registered owner of the vehicle or with their prior consent, unless in the case of a valid warrant or court order.
At least 16 states have statutes expressly addressing the use of license plate readers or the retention of the data they collect, according to the National Conference of State Legislatures.
The bills have been referred to the House Judiciary Committee. A hearing date has not yet been set.
