Baja California’s vehicle regularization program has processed only about half of the cars that need legal documentation, leaving roughly 760,000 vehicles still out of compliance. Jesús García Castro, director of the state tax authority (SAT BC), reported the backlog as of May 31.
The state identified 1.528 million vehicles requiring regularization. Of those, approximately half have completed the process. The remaining cars, many of them older U.S.-plated models brought across the border informally over the years, still lack proper Mexican registration.
Why the Backlog Matters
Unregistered vehicles have long been a fixture on Baja California’s roads. Known colloquially as “autos chocolate,” these cars were driven into Mexico from the United States without going through formal import procedures. State officials have previously claimed that more than 80 percent of crimes in Baja California involve unregistered vehicles, making the regularization push a public safety priority as well as a revenue issue.
The federal government extended the regularization deadline to November 30, 2026, after earlier cutoff dates passed with large numbers of vehicles still unprocessed. The program allows owners to pay a fee and obtain Mexican plates, bringing their cars into the legal system.
What This Means for Vehicle Owners
Drivers of unregistered or improperly documented vehicles face real consequences. Fines, impoundment, and complications at military or police checkpoints are all possible outcomes. Permanent residents in Mexico are generally excluded from the Free Zone exception that allows foreign-plated vehicles to circulate without importation, according to Mexican Customs Law (Ley Aduanera) Article 106.
For U.S. citizens and other foreigners living in Baja California on temporary or permanent residency, the rules depend on immigration status. Tourists and temporary residents may drive foreign-plated vehicles with valid registration and insurance. Permanent residents whose vehicles stay full-time in Mexico should regularize or formally import them.
The SAT BC office handles the regularization process at its locations in Tijuana, Mexicali, Ensenada, and other cities across the state. Owners typically need proof of ownership, identification, and the regularization fee to complete the paperwork.
With roughly five months remaining before the November 2026 deadline, the pace of processing will need to accelerate sharply for the state to clear its backlog. García Castro’s comments were first reported by Zeta Tijuana.
