Newly released federal files are pulling back the curtain on the deadly I-35 pileup in north Austin, painting a picture of state licensing mistakes and thin trucking-company paperwork ahead of the crash that killed five people and injured more than a dozen others. The wreck happened late on March 13, 2025, on southbound I-35 near Parmer and Howard lanes, when a Volvo tractor-trailer slammed into a line of vehicles waiting inside an overnight work zone.
According to KXAN, federal files show the driver, whose Employment Authorization Document (EAD) expired in 2022, received a standard Texas Class A commercial driver’s license in 2021 instead of a non-domiciled CDL that should have been tied to his authorized work period. KXAN reports that investigators traced how that licensing decision, paired with the carrier’s sparse records, fed into subsequent federal reviews.
The National Transportation Safety Board’s technical reconstruction helps explain why the impact was so catastrophic. Event data from onboard control modules and recorders shows the truck was traveling roughly 65 to 71 mph in the 10 seconds before impact and did not make sustained braking maneuvers as traffic stacked up. The estimated relative impact speed was about 69 mph, and the tractor-trailer traveled roughly one-tenth of a mile into the stopped queue before coming to rest, according to the NTSB.
Licensing failures that matter
Federal reviewers told investigators that Texas mishandled commercial licensing rules when it converted the driver’s out-of-state credential and issued a full-term CDL that did not expire with his EAD. The Federal Motor Carrier Safety Administration (FMCSA) highlighted the error in its regulatory filings. As outlined in FMCSA, the Austin crash became one of several fatal cases cited as the agency tightened nationwide standards for non-domiciled CDLs and prompted some states to pause or revise how they issue those licenses.
Carrier records and telematics
The NTSB’s review of motor-carrier operations found that ZBN Transport had no formal written hiring process, provided little documentation of road-test results, and leaned on an outside agent to handle compliance paperwork. Investigators said those gaps made it harder to confirm the driver’s qualifications and history.
The NTSB docket includes an extract from a Motive electronic logging device showing dozens of speeding alerts and multiple hard-brake events in the days leading up to the crash. A post-crash compliance review in the file notes that ZBN was unable to secure replacement insurance after the wreck and has since stopped operating, according to the NTSB.
Legal fallout
The driver, Solomun Weldekeal-Araya, was arrested after the crash and initially charged with intoxication manslaughter and intoxication assault. A judge later reduced his bond while prosecutors reviewed the evidence, according to local reporting. Injured motorists have filed lawsuits against Weldekeal-Araya, ZBN Transport, and Amazon Relay contractors, including at least one complaint seeking around $100 million in damages, according to reporting from KSAT. Defense attorneys have pushed back on some of the early impairment findings, and toxicology results remain a point of contention in court.
Outside the courtroom, regulators say the crash helped speed up national policy changes. FMCSA’s rulemaking tightened verification and documentation requirements for non-domiciled CDLs and led Texas to suspend certain non-domiciled issuances while it retools its processes, according to FMCSA. Local and federal investigators, along with the NTSB team that continues to maintain the docket, say they will keep examining work-zone design, carrier oversight, and driver fitness as they complete the public record and develop safety recommendations.
