Two separate legal fights are underway, and it matters which is which. The D.C. Circuit case, Rivera Lujan v. FMCSA, is a direct challenge to the rule itself; the emergency stay was denied on May 5, 2026, briefing is continuing, and oral argument is set for September 15, 2026. See FreightWaves's coverage of the briefing schedule. A separate suit, filed by nineteen non-domiciled CDL holders in the Southern District of Florida on April 15, 2026, has not produced a ruling yet. See CDLLife's report.
Separately, USDOT withheld $73,502,543 in federal highway funds from New York, announced April 16, 2026, after an audit found 107 of 200 sampled New York-issued CDLs noncompliant with the rule; New York is challenging that decision in the Second Circuit. That is a funding dispute between a state and the federal government, not a court ruling on whether the rule itself is lawful, and the two are worth keeping apart. See FreightWaves's report.
Enforcement is also showing up outside the courtroom. In Florida, following a fatal Florida Turnpike crash, the state Attorney General announced on August 25, 2025 that agricultural-interdiction and weigh stations would add immigration-document and English-proficiency checks, carried out by state Department of Agriculture (FDACS) officers certified under a federal 287(g) agreement, not by ICE agents directly. See CBS News Miami's report.
One thing worth knowing if you assume the trucking lobby is fighting this on your drivers' behalf: it isn't. Both the Owner-Operator Independent Drivers Association (OOIDA) and the American Trucking Associations have come out in support of the rule. Don't assume the big trade groups are advocating against it, for you or for your drivers.
