Unmarked Phoenix police vehicles sporting Mexican license plates have ignited a public backlash, and city leaders are now scrambling to calm things down.

Phoenix police said Monday it will no longer use Mexican plates on unmarked department vehicles after a social media video raised alarms among drivers and advocates. Chief Matt Giordano ordered the practice stopped and launched an internal review, according to city officials.

The viral clip appears to show several unmarked SUVs and sedans with license plates issued in Mexico pulling over a car near 30th Avenue and Indian School Road, leaving people wondering who, exactly, was conducting the stop.

A Phoenix Police Department spokesperson told 12News that using non-U.S. plates “created uncertainty about who was conducting the stop” and said Giordano has discontinued the practice on unmarked vehicles. The spokesperson also said the officers involved were conducting a traffic stop related to a person wanted on a felony warrant, the outlet reported.

Department vehicle rules

Unmarked and undercover cars are part of the Phoenix fleet, but their deployment is not supposed to be a free-for-all. Their use is governed by written operations orders that spell out when they may be used and how incidents must be documented.

According to the Phoenix Police Department’s vehicle operations order, undercover vehicles are permitted in certain situations, but supervisors must follow oversight and reporting procedures whenever those cars hit the street.

Why people worry

Community advocates say cars that look unofficial or carry foreign plates can easily be mistaken for federal immigration agents or even impersonators. That, they argue, can chill crime reporting and make people less likely to interact with local police at all.

Reporting from southern Arizona has shown that unmarked cars with Mexican or Sonoran plates have previously stirred fear and confusion, a pattern critics say undermines trust between law enforcement and immigrant communities. According to KOLD, residents and advocates there raised similar concerns after unmarked vehicles with Mexican-issued plates were spotted during enforcement actions.

What comes next

Phoenix officials say the internal review will look at whether the department’s practices need clearer rules or additional training around unmarked vehicles and plate usage.

The move comes as state lawmakers and privacy advocates are already battling over how far police should be allowed to go with tracking technology such as license plate readers. That broader fight has put a spotlight on how agencies monitor drivers, as reported by KJZZ.

If you are ever unsure during a traffic stop, public safety groups recommend staying in a well-lit public area, asking to see official credentials, and calling 911 if you feel unsafe.
