Judge Blocks DHS Access to 17 Million CDL Records, Sets Sept. 10 Injunction Hearing

A federal judge in Alexandria, Virginia, granted a temporary restraining order on Aug. 20 blocking the U.S. Department of Transportation, the Federal Motor Carrier Safety Administration and the Department of Homeland Security from obtaining 17 million Commercial Driver's License Information System records the agencies had demanded from the American Association of Motor Vehicle Administrators.

The order, issued by Senior U.S. District Judge Anthony J. Trenga in State of Illinois, et al. v. U.S. Department of Transportation, et al., No. 1:26-cv-2547 (AJT-IDD), bars AAMVA from transferring the CDLIS Master Pointer Records and prohibits federal defendants from terminating or threatening to terminate AAMVA's or the states' federal contracts and funding over noncompliance. A related administrative stay in a companion DHS subpoena matter, 1:26-mc-00019 (AJT-IDD), was vacated the same day and folded into the TRO proceeding.

The court found the 21 plaintiff states and D.C. are likely to succeed on claims that the data demand violates the Commercial Motor Vehicle Safety Act's consultation requirement, the Driver's Privacy Protection Act, the Privacy Act's notice-and-restriction provisions, and the Administrative Procedure Act's bar on arbitrary and capricious agency action. Judge Trenga's order states the CDLIS records "are not controlled by FMCSA" and "belong to the states," rejecting the government's position that the transfer was routine oversight.

How the dispute escalated

FMCSA first demanded five years of CDLIS records from AAMVA on June 25. AAMVA raised legal objections five days later. The dispute hardened on Aug. 11, when FMCSA threatened to terminate AAMVA's federal contracts if the records weren't delivered by Aug. 17, and DHS separately issued a subpoena for the same data. States sought emergency relief, and the court entered the TRO on Aug. 20 — one day after DHS's threatened deadline. A preliminary injunction hearing is scheduled for Sept. 10 at 10 a.m. in Courtroom 900 of the Alexandria federal courthouse, with the states' injunction motion due Aug. 27 and the government's response due Sept. 3.

Transportation Secretary Sean Duffy pushed back publicly, arguing in a DOT filing that "without access to CDL data, FMCSA is materially hindered in its statutory obligation to conduct oversight of states' CDL issuance and prevent the regulatory CDL framework from fracturing into national dis-uniformity," and separately calling the suit an attempt to make it "easier for dangerous illegal immigrant truck drivers to operate a big rig," according to Landline Media's review of the government's court filings.

California Attorney General Rob Bonta, one of the coalition leads, said the ruling "marks another important step in making sure Americans' privacy rights remain protected," in a statement posted alongside the orders on his office's press page.

What's actually at stake

The data set covers names, dates of birth, license numbers and Social Security numbers for CDL holders nationwide — records DHS has said it wants partly to cross-check against immigration status, according to Overdrive's reporting on the underlying dispute. The plaintiff coalition spans Arizona, California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Maine, Maryland, Massachusetts, Michigan, Nevada, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Vermont, Virginia, Washington and Wisconsin, with Minnesota joined to the separate DHS subpoena action.

What it means for carriers and brokers

• No change to routine verification. The TRO freezes a bulk federal data transfer, not the SAFER and Licensing & Insurance lookups carriers and brokers already use to check CDL status one driver at a time. Day-to-day hiring and vetting workflows are unaffected for now.
• The real deadline is Sept. 10. If the states lose the preliminary injunction fight, FMCSA and DHS could get bulk access within weeks, opening the door to cross-referencing CDL rolls against immigration status — a shift carriers with large immigrant driver pools should be tracking, not the TRO itself.
• Contract leverage is the mechanism to watch. FMCSA's threat to pull AAMVA's federal funding is the same lever it could point at state licensing agencies more broadly if it prevails — a precedent with implications well beyond this one data set.
