Iowa Troopers Reveal Commercial Vehicle Violations, Urge Thorough Pre-Trip Inspections

Iowa troopers share photos of commercial vehicle violations as a reminder to conduct thorough pre-trips

The Iowa State Patrol’s Commercial Motor Vehicle Unit is reminding drivers to take a close look at their equipment before starting work after recent inspections uncovered several serious defects.

In social media posts, Iowa troopers shared photographs from commercial vehicle inspections and urged drivers to complete a thorough pre-trip inspection before beginning each workday. Troopers also recommended conducting additional equipment checks during the day.

“Here are some photos from recent inspections. Please ensure a thorough inspection is conducted before the start of each workday. Additionally, doing random checks throughout the day is always a good practice,” the unit said in an Oct. 12 post.

The images showed equipment problems that inspectors said could have been identified before the vehicles reached the road. In one example, troopers pointed to an inoperative brake. The condition was indicated in part by a heavily rusted braking surface, according to the ISP.

Troopers shared a second photograph from the same truck to provide a clearer view of the brake-related defect. The agency also posted additional images showing other commercial vehicle violations, although the available information did not identify every defect or provide details about the carriers and drivers involved.

The inspection photos were shared as a maintenance reminder rather than as a report of a single enforcement operation. The ISP Commercial Motor Vehicle Unit said some equipment problems can develop over time, making regular inspections and timely repairs especially important.

In an earlier April 28 post, the unit described photographs from recent commercial vehicle inspections around Iowa as “eye-opening.” The agency acknowledged that some mechanical problems can occur without warning, but said many defects appear to have been developing for an extended period.

“Out-of-service violations are always cheaper and easier to fix in your own yard rather than roadside!” the ISP said.

For professional drivers, an out-of-service defect can interrupt a trip, delay a delivery and require repairs away from the carrier’s normal shop or maintenance facility. A problem found during a pre-trip, by contrast, can often be documented and addressed before the truck and driver are committed to a route.

A proper inspection also gives drivers an opportunity to identify developing problems that may not be immediately obvious from the cab. Brakes, tires, wheels, lighting equipment, coupling components and other safety-related systems require close attention during the inspection process. Drivers are responsible for reporting defects and should not operate equipment they believe is unsafe.

The Iowa reminders came as commercial vehicle enforcement agencies across the country continued to emphasize equipment condition and inspection compliance. The Commercial Vehicle Safety Alliance’s International Roadcheck campaign was scheduled throughout North America from May 12 through May 14, 2026, bringing additional attention to commercial vehicles and their equipment.

Roadside inspection activity is not limited to campaign dates, however. Commercial vehicles may be inspected at any time, and defects that affect braking, tires, lighting, load securement or other safety systems can result in violations or an out-of-service order.

The ISP posts did not state how many trucks were inspected, how many violations were issued or whether any crashes were connected to the equipment shown. They did make a straightforward point: a pre-trip inspection should be more than a quick walk around the tractor and trailer.

Drivers are encouraged to look for signs of wear, damage or failure and to follow their company’s inspection procedures. When a defect is found, it should be reported through the proper maintenance process before the vehicle continues in service.

By sharing inspection photographs, Iowa troopers are emphasizing that routine checks can help identify problems before they become roadside violations or create a safety risk. For drivers, the practical message is to allow enough time for a careful inspection at the start of the day and to recheck critical equipment during the trip.
