Iowa state authorities are warning commercial vehicle drivers about the serious danger associated with the technical condition of trailers and wheel assemblies. The reason for this is two incidents in one week, one of which resulted in a fatality.
On the evening of January 25, 2026, on Interstate I-80 in Jasper County, a set of wheels detached from a semi-trailer on the move. The wheels crossed the median and crashed into an oncoming passenger car. The driver of the car died at the scene. The information was confirmed by an official report from the Iowa State Patrol.
Two days later, on January 27, a patrol officer from the Iowa State Patrol's commercial division witnessed another similar incident: a wheel detached from a trailer while driving on I-380. In this episode, there were no injuries, but the situation once again highlighted the scale of the problem.
The commercial division of the Iowa State Patrol issued a stern public appeal to drivers and carriers. According to the patrol officers, such accidents are directly related to insufficient vehicle inspections.
“We are literally begging drivers to check their equipment before heading out,” police representatives said after the second incident.
These words were reported by local television, citing the Iowa State Patrol, which covered the fatal accident on I-80 (KCCI).
The Federal Motor Carrier Safety Administration (FMCSA) has long indicated that maintenance is the key factor in preventing such tragedies. According to federal regulations, carriers are required to systematically inspect and maintain vehicles, and drivers must ensure the equipment is in good working order before trips.
These requirements are outlined in the FMCSA's vehicle maintenance rules for commercial vehicles (FMCSA – Vehicle Maintenance).
A wheel detachment at speed is one of the most dangerous malfunctions for all road users. Even a single incident can lead to a fatal outcome, and the recurrence of such incidents in a short period indicates a systemic problem.
For drivers and fleet owners, this is not just a matter of adhering to formalities but a real responsibility for lives on the road. Regular pre-trip inspections, checking the tightness of nuts, and the condition of hubs are minimal measures that can prevent a tragedy.
