The U.S. Department of Justice has filed a lawsuit against Maine after the state refused to issue undercover license plates to federal law enforcement agents — a denial the federal government says hampers covert operations on Maine roads.
The suit, reported Wednesday, May 28, 2026, by WABI, sets up a direct clash between state motor vehicle authority and federal law enforcement needs. Maine declined to provide the plates, though the state’s specific rationale wasn’t immediately detailed in initial reports.
Undercover plates let federal agents — working drug cases, human trafficking investigations, and similar operations — drive vehicles that don’t trace back to the government through a standard registry search. Without them, a subject under surveillance could run a plate and make an agent.
The Justice Department’s decision to sue rather than negotiate further suggests the dispute isn’t new. Whether Maine acted under a state statute, a policy directive, or a governor’s order hasn’t been confirmed.
No hearing date in the case had been announced as of Wednesday evening.
