393.209(a) Cracked/Broken Wheel or Rim: Will It Put Me Out of Service?

Yes—there is a strong likelihood. Across our 13 million inspection records, 393.209(a) citations result in an out-of-service order 76.0% of the time. That's more than double the national average OOS rate of 31.4% across all FMCSR codes. A cracked or broken wheel or rim is treated as an immediate safety hazard by inspectors, which explains the high OOS rate. If cited, assume you will be pulled from service until the wheel or rim is repaired or replaced and re-inspected.

This violation carries a severity weight of 7 points. CSA point accumulation depends on the 30-day multiplier—your first occurrence in 30 days counts as 7 points, a second within the same window multiplies to 14 points, and a third escalates to 21 points. These points roll into your carrier's BASIC score for Vehicle Maintenance, affecting your company's CSA rating and insurance costs. The higher the severity weight, the faster your carrier's score deteriorates with repeat violations.

First: Stop operating the vehicle immediately if placed out of service. Second: Contact your dispatcher and safety manager with the inspection report and the specific wheel or rim identification. Third: Arrange transport to a qualified repair shop—not a fuel stop, a full-service truck repair facility. Fourth: Have the shop perform a full wheel/rim inspection (both sides), document the repair with photos and a written statement, and obtain a new inspection sticker or violation clearance. Fifth: Report back to your safety team with documentation before attempting to return to service.

Yes, it is significantly more serious. Our data shows 393.209(a) has a 76.0% out-of-service rate compared to similar codes: Inoperable required lamps (393.9(a)) at 15.4% OOS, Windshield condition (393.78) at 0.3% OOS, and Lighting devices (393.11) at 1.8% OOS. Only Inspection/repair/maintenance general violations (396.3(a)(1)) approach this severity at 45.3% OOS. Wheels and rims are structural safety components; inspectors treat breaks or cracks as imminent failure risks, triggering immediate out-of-service action in three of four citations.

Yes, you can contest it through the DataQs Roadside Inspection Dispute (RDR) process, but success depends on the evidence. If the inspection report contains factual errors—wrong vehicle identification, confusion with another unit, or inspector misidentification of the damage—you have grounds. However, if the wheel or rim truly shows visible cracking or breakage, the citation will likely stand. You have 90 days from the inspection date to file. Work with your carrier's safety department to gather photographic evidence and maintenance records showing recent inspections or repairs.

It is rare. Our inspection database shows only 200 all-time citations for 393.209(a), making it rank #1212 out of 3,036 FMCSR codes by volume. In the last 12 months, there have been 0 citations recorded, and 0 in the last 90 days. This suggests that most carriers and drivers catch wheel and rim damage during pre-trip inspections before roadside enforcement occurs. The low frequency does not mean low severity—when it is cited, 76% of violations result in out-of-service status because the damage is typically obvious and critical.

Immediately. Do not drive the vehicle even short distances. A cracked or broken wheel or rim can catastrophically fail under load, causing loss of control, tire separation, or a rollover—endangering your life and others on the road. Structurally compromised wheels are not something to "limp to the next stop" with. The 76.0% out-of-service rate reflects inspector judgment that the damage is an imminent safety hazard. If you discover this damage yourself during a pre-trip, report it to your dispatcher and do not move the truck until it is repaired and cleared by a qualified technician.

In our all-time records, five carriers each have 2 citations: Premier Dumpsters LLC (USDOT 3621623), West Wind Logistics Inc (USDOT 1302563), LED Inc (USDOT 2519984), Best Carrier Inc (USDOT 4036766), and Siffrin Inc (USDOT 2516353). Several other carriers have 1 citation each. The low citation count across all carriers indicates that 393.209(a) enforcement is sparse industry-wide. However, for individual drivers and fleets, the impact per citation is severe: with a 76% OOS rate and a severity weight of 7 CSA points, even one violation can significantly disrupt operations and carrier ratings.
