The FBI Wants to Track Your Car Across America. Here's What That Means.

In May 2026, the FBI posted a request asking private companies to help build a nationwide system that reads and records license plates. The agency wants the system to cover 75 percent of the United States and its territories, and to deliver information about where cars are and who's driving them almost instantly.

This is a big step up from how things work today. Right now, the FBI has formal agreements with license plate reader systems in 46 states and some local police departments. The new plan would make that coverage much larger and faster.

How License Plate Readers Work

License plate readers are cameras that photograph your license plate as you drive. They record the plate number, the time, and the GPS location. That data gets stored in a searchable database.

Think of it like a giant filing system. Instead of one police officer writing down what cars pass by, thousands of cameras across the country automatically capture every vehicle. A detective can then search that filing system to find where a particular car has been — and when.

The FBI already uses these systems. The agency says they've helped locate 818 people on the Wanted Persons List and 19 missing people. Police also use the technology to track suspected smuggling operations.

What the FBI Already Has in Place

The FBI is not starting from scratch. Other federal agencies have been building license plate reader networks for years.

The Department of Homeland Security uses them at the border to detect and identify people entering the country illegally. The U.S. Border Patrol monitors millions of American drivers nationwide using license plate readers, looking for what it calls suspicious travel patterns.

Private companies also run license plate reader systems. Flock Safety, for example, operates cameras in more than 4,000 communities across the country. Local police departments pay to access this data.

Where Problems Have Emerged

Flock Safety temporarily stopped working with the Department of Homeland Security on license plate reader programs because of confusion and concern about how the data would be used. An audit later found that Homeland Security had accessed Illinois license plate data in a way that violated state law. This shows that when different agencies share the same data, conflicts can arise.

There has also been a security breach. Photos of travelers and license plates collected at a U.S. border point were exposed in a cyberattack on a company working for Homeland Security. This points to a real risk: the bigger the database, the more valuable a target it becomes for hackers.

What Lawmakers and Rights Groups Are Concerned About

Some senators have begun raising alarms. Senator Ed Markey has called the Border Patrol's license plate reader program "an invasive surveillance network that poses a serious threat to privacy and civil liberties."

Civil liberties organizations like the ACLU and the Electronic Frontier Foundation have filed public records requests to understand how police departments are using license plate readers. They want to know more about the scope of these systems and whether they need better rules.

Some cities have rejected Flock Safety contracts altogether. Local officials worry that connecting to these networks means their communities are effectively enrolled in a federal surveillance system they did not sign up for.

The Bigger Picture

The technical capability now exists to create a comprehensive vehicle tracking system that could monitor where nearly every car in America goes. This kind of expansion has a history in American law enforcement. We have seen this pattern before—when technology built for one legitimate purpose (telephone networks for communications, for example) later became the foundation for mass surveillance that went far beyond what was originally planned.

The key tension here is this: license plate readers do help law enforcement solve crimes and find missing people. At the same time, the systems are blunt instruments. They record the movements of everyone who drives—not just suspects—and that location data can reveal a lot about someone's life: where they worship, where they visit doctors, where they go in the evening.

The FBI's new plan would make this tracking faster, broader, and more centralized. What happens next depends on decisions that lawmakers, courts, and local communities make in the months and years ahead.
