Metropolitan Trucking Inc. filed against the agency on September 4. The docket is thin. The regulatory moment it landed in is not.

On September 4, 2026, Metropolitan Trucking Inc. filed a civil complaint against the Federal Motor Carrier Safety Administration in the United States District Court for the Southern District of Florida. The case is docketed at 1:26-cv-26139. No judge has been assigned. The complaint isn’t in RECAP yet, so the specific claims aren’t publicly available. What is on the table is who Metropolitan is, what FMCSA has been doing to carriers in South Florida this year, and why a 23-year-old Miami operation with 14 trucks decided that federal court was the next step.

Metropolitan Trucking Inc. holds USDOT number 975554 and MC number 413048. Its registered address is 398 NE 79th Street, Miami, Florida 33138. According to FMCSA’s Safety Measurement System, the company registered with the agency on August 30, 2001, runs a fleet of 14 truck tractors and 13 drivers, and operates as both a for-hire carrier and a broker. The SMS record, as of January 30, 2026, shows zero reported crashes in the prior 24 months. A third-party compliance aggregator scores the company at 50 out of 100, flagging no active insurance policies on file with FMCSA. That last item matters, and it matters in a specific way that we’ll get to.

The Southern District of Florida has been an unusually active venue for FMCSA litigation in 2026. In April, nineteen non-domiciled CDL holders living in Florida filed in that same courthouse, naming FMCSA, the U.S. Department of Transportation, and the Florida Highway Safety and Motor Vehicles agency as defendants. That case challenged FMCSA’s February 13, 2026 final rule on non-domiciled commercial driver’s licenses, which effectively bars asylum seekers, DACA recipients, and others with work authorization from holding a CDL. The rule eliminated roughly 200,000 CDL holders from the workforce in a single regulatory action. Metropolitan Trucking hauls general freight, fresh produce, refrigerated food, beverages, building materials, and a dozen other commodity categories in South Florida. A Miami carrier running 14 tractors with 13 drivers operates in a labor market where non-domiciled CDL holders represent a meaningful share of available drivers. The record does not establish whether that’s the thread that connects Metropolitan to this lawsuit. It’s the most plausible thread based on the record.

A second thread runs through Metropolitan’s insurance status. The FMCSA SMS and third-party aggregator data show no active insurance policies on file. That’s not necessarily a violation; the SMS record pulls from the Licensing and Insurance system, which updates hourly, and a carrier can operate legally while refiling a policy. What it is, in the post-Montgomery world, is a flashing yellow light for every broker that touched a Metropolitan load. On May 14, 2026, the Supreme Court ruled 9-0 in Montgomery v. Caribe Transport II, LLC that state negligence claims against freight brokers for carrier selection are not preempted by the Federal Aviation Administration Authorization Act. The safety exception at 49 U.S.C. § 14501(c)(2)(A) preserves state authority to regulate safety with respect to motor vehicles, and the Court held that a negligent-hiring claim against a broker falls squarely inside it. Every broker that tendered a load to Metropolitan after that ruling is now in a jurisdiction where a jury gets to ask whether the broker checked the carrier’s insurance status before booking the truck. A carrier with no active policy on file in the FMCSA system is a carrier a broker cannot afford to defend.

That’s the world Metropolitan is operating in. An agency that has been aggressive on enforcement in 2026, a CDL workforce being dismantled by regulatory action, a Supreme Court decision that turned every broker’s carrier-selection file into potential trial evidence, and a Miami fleet with a compliance gap visible on a public federal database. The lawsuit doesn’t have to be about any one of those things to be shaped by all of them.

The mechanism a carrier uses to challenge FMCSA in federal district court is narrow. Agency actions go to the courts of appeals under 49 U.S.C. § 521 for most civil penalty matters. A district court complaint against FMCSA typically means one of three things: a constitutional claim, an APA challenge to a final agency action that the statute doesn’t route elsewhere, or an emergency request for injunctive relief — a carrier trying to keep trucks rolling while a dispute over its authority or safety rating is resolved. The Southern District of Florida is the right venue for a Miami carrier. A judge hasn’t been assigned yet, which means the case is in its first days. The docket number alone tells us the case is real. The complaint will tell us whether it’s a fight over paperwork or something with broader consequences for the industry.

The record doesn’t establish what specifically FMCSA did to Metropolitan that Metropolitan decided it needed a federal judge to address. That answer is in the complaint, and the complaint isn’t public yet.

Pull the complaint from the S.D. Florida CM/ECF system. The docket number is 1:26-cv-26139. If Metropolitan is challenging a safety rating, an out-of-service order, or an authority action, the facts in that document will either confirm or contradict the profile the federal database shows. A carrier with a clean crash record and an active docket number suing the agency that regulates it is a story worth understanding precisely. Not generally. Get the complaint.
