California Data-Sharing Plan Sparks Deportation Fears for Over 1 Million Immigrant License Holders

Key facts

• California plans to share driver’s license data with the American Association of Motor Vehicle Administrators (AAMVA).
• Over 1 million Californians hold licenses under a program for undocumented residents, initiated over a decade ago.
• The data transfer is tied to compliance with the federal REAL ID Act, which took full effect in May 2025.
• Critics warn that the database includes partial Social Security Numbers or placeholder codes, potentially flagging undocumented immigrants.
• Governor Gavin Newsom’s office asserts the system contains no immigration status identifiers, addresses, or search capabilities by status.
• The DMV is requesting $55 million from the state budget to implement the data transfer.
• Transportation Secretary Sean Duffy has threatened to withhold federal funding from California over commercial driver’s license issues.
• California has revoked 21,000 commercial driver’s licenses after confirming problems with immigration status verification.

A Promise Broken?

California is moving to share sensitive driver’s license data with a national network, a decision that has ignited backlash from immigrant rights advocates who fear it could expose over one million undocumented residents to deportation. The state plans to upload the information to the American Association of Motor Vehicle Administrators (AAMVA), which operates a multi-state system used to flag duplicate licenses. The move is tied to compliance with the federal REAL ID Act, which since May 2025 requires compliant identification for domestic air travel and access to federal facilities. But critics argue that once the data leaves state hands, California loses control over how it is used. “This is a direct betrayal,” said Tracy Rosenberg of Oakland Privacy, contending that the state is reneging on a promise made when it began issuing licenses to undocumented residents more than a decade ago.

The Scope of the Program

More than one million Californians hold driver’s licenses under the state’s program for undocumented residents, which was designed to improve road safety while shielding applicants’ information from immigration enforcement. At the heart of the controversy is what the shared data will contain. The AAMVA system includes partial Social Security Numbers — or a placeholder code for those without one — which critics say could effectively flag undocumented immigrants. Governor Gavin Newsom’s office has pushed back, stating that the system contains no identifying information about immigration status, no addresses, and no ability to search for people by immigration status. State officials also emphasize that access to the database is limited and bulk searches are not permitted. However, advocates warn that subpoenas or requests routed through local agencies could still open the door to federal immigration authorities.

Federal Pressure and Funding Threats

The data-sharing proposal unfolds against a backdrop of heightened federal scrutiny of driver’s license practices. Transportation Secretary Sean Duffy has publicly threatened to withhold millions in federal funding from several states, including California, after investigations found that commercial driver’s licenses remained valid long after immigrants’ legal status expired. Duffy specifically targeted California, citing a fatal August crash in Florida caused by a tractor-trailer driver who was not authorized to be in the U.S. and had obtained a license in California. In response, California initially defended its practices, with Governor Newsom sparring with Duffy in statements and social media posts. But the state later revoked 17,000 commercial driver’s licenses, a number that has since grown to 21,000. Duffy has not pulled the threatened $160 million in funding, but he did revoke a separate $40 million because California is the only state not enforcing English language requirements for truckers.

National Crackdown on Immigrant Truck Drivers

The federal government’s crackdown on commercial driver’s licenses for immigrants has now identified problems in eight states: California, Pennsylvania, Minnesota, New York, Texas, South Dakota, Colorado, and Washington. The Transportation Department sent letters detailing concerns to these states after several deadly crashes involving unauthorized immigrant drivers. In addition to the Florida crash that killed three people, a fiery California crash in October also killed three people and involved a truck driver in the country illegally. Duffy proposed new restrictions in September that would severely limit which noncitizens can obtain licenses to drive semis or buses, but a court has put those rules on hold. Meanwhile, the Trump administration has been enforcing existing English language requirements for truckers since the summer. As of October, about 9,500 truck drivers have been pulled off the road nationwide for failing to demonstrate English proficiency during traffic stops or inspections.

State-Level Changes Elsewhere

Beyond California, other states are also revising their driver’s license regulations. In Florida, updated teen licensing requirements took effect July 1, 2025, under legislation signed by Governor Ron DeSantis. Teens aged 15–17 must now complete a state-approved 50-hour Driver Education/Traffic Safety (DETS) classroom course before obtaining a learner’s license, separate from the mandatory four-hour Traffic Law and Substance Abuse Education (TLSAE) course. In Ontario, Canada, the provincial government introduced Bill 60 on October 23, 2025, aiming to tighten eligibility requirements for driver’s licenses to combat fraud. The bill, part of the Fighting Delays, Building Faster Act, 2025, would require new applicants for all license classes to provide residency and legal presence verification. It also proposes a mandatory minimum waiting period between obtaining a Class G and Class A commercial license, though the length of that period is not specified.

What Comes Next

California’s data-sharing proposal remains tied to the state budget process, with the DMV seeking $55 million to carry out the transfer. Lawmakers are weighing the plan as critics warn of far-reaching consequences. The outcome could set a precedent for how states balance compliance with federal identification standards against protections for undocumented residents. At the federal level, the court-ordered hold on Duffy’s proposed restrictions for noncitizen commercial drivers leaves the regulatory landscape uncertain. The Transportation Department may withhold nearly $75 million from Pennsylvania if it is not satisfied with the state’s actions. As states and the federal government continue to clash over driver’s license policies, the stakes for millions of immigrants — and for road safety — remain high.

The bottom line

• California’s plan to share driver data with AAMVA could expose over 1 million undocumented license holders to deportation risks.
• The data transfer is required for REAL ID compliance, but critics say it breaks a promise of confidentiality made when the license program began.
• Federal Transportation Secretary Sean Duffy has threatened funding cuts to multiple states over commercial driver’s license issues, with California losing $40 million so far.
• Eight states have been flagged for problems with immigrant commercial driver’s licenses, following deadly crashes involving unauthorized drivers.
• About 9,500 truck drivers have been pulled off the road nationwide for failing English proficiency tests since October 2025.
• Other states, including Florida and Ontario, are also implementing new driver’s license requirements, reflecting a broader trend of tightening regulations.
