Most vehicle databases begin with makes and models. The National Police Car Archives begins with police departments.
Visit the National Police Car Archives
Its stated goal is absurdly large: show law-enforcement vehicles from every agency in the United States. The site says there were 17,541 agencies in its working count from 2018, ranging from villages and major cities to universities, transit systems, parks, railroads, and federal organizations.
The archive currently reports 38,703 photographs representing 9,421 agencies — more than 53 percent of U.S. law-enforcement agencies by its count.
That makes it more than a gallery of Crown Victorias with light bars.
A uniform is also a paint scheme
Police vehicles are unusually good historical objects because local identity gets painted directly onto standardized machinery.
The underlying car may be a Chevrolet, Ford, Dodge, motorcycle, SUV, pickup, or specialty vehicle. What changes is the livery: badges, striping, typography, emergency-light placement, unit numbers, slogans, and the visual language an agency uses to announce itself in traffic.
Collected at national scale, those photographs become a record of municipal design as much as automotive equipment.
The site is arranged geographically and institutionally, with state pages plus sections for federal agencies, railroads, and Washington, D.C. It also maintains a missing-agency list and explicitly asks visitors to contribute photographs.
The archive dates its copyright from 2003 and identifies James Duff as webmaster. In 2026 the front page also describes an ongoing rebuild, which is a familiar problem for long-running personal archives: the collection outlives the software used to maintain it.
That persistence is what makes the site worth noting.
A commercial image search can show thousands of police cars. It does not naturally preserve the question, “Do we have a vehicle from this exact agency yet?”
CacheRat’s 1,967 Ancient Web Domains research list contains many projects built around that kind of stubborn completeness: one person or small group decides a category deserves an index and then keeps filling holes for years.
The National Police Car Archives is one of the clearest examples.
