FMCSR 393.207B: Frame Crack Citations & OOS Risk

Not automatically—but it happens about half the time. Across our inspection records, 393.207B resulted in an out-of-service order in 51.1% of cases (1,046 out of 2,048 all-time citations). That's significantly higher than the 31.4% average OOS rate across all FMCSR codes. Whether you're placed OOS depends on the inspector's assessment of frame severity and the immediate safety risk. If your frame is cracked but structurally sound, you may be cited but allowed to continue. If the crack is severe enough to compromise the vehicle's integrity, expect an OOS order and don't move the truck.

This violation carries a severity weight of 8 points. The total impact on your CSA score depends on how many times you're cited within a rolling 30-month window and which BASIC category the violation falls under. A single citation counts once; multiple citations within 30 days are typically weighted cumulatively. Since frame defects pose structural safety risks, this is treated as a serious maintenance issue. Check your CSA profile at Safety Central to see your current Unsafe Vehicle and Vehicle Maintenance BASIC percentages, both of which this violation affects.

Immediate steps:

1. Do not move the truck if you were placed out of service.
2. Document the citation with the inspector's report, photos, and specific location of the frame damage.
3. Contact a certified frame shop or your carrier's maintenance team immediately.
4. Inspect related systems: Our data shows frame defects often co-occur with brake tubing issues (38 shared inspections) and coupling device problems (43 shared inspections). Have the shop check brakes, steering, and tow equipment.
5. Get written repair confirmation before submitting an OOS appeal or attempting to pass re-inspection.
6. Report to your carrier's safety department if you're a driver for a fleet.

Yes, it's above-average serious. The 51.1% OOS rate for 393.207B exceeds the 31.4% all-FMCSR average by 20 percentage points. Among similar vehicle maintenance codes, it's more likely to result in OOS than Windshield condition defects (0.3% OOS) or Lighting device violations (1.8% OOS), but less severe than general inspection/repair failures (45.3% OOS). Frame integrity is a structural safety issue, so inspectors treat it as more urgent than cosmetic or electrical defects. A cracked frame can affect steering, braking, and load distribution, which is why the OOS threshold is high.

Yes. Frame damage is a visible, physical finding, not a documentation issue, so contestability depends on whether the inspector correctly identified and photographed the crack. Use DataQs (the Federal Motor Carrier Safety Administration's data quality platform) to challenge the citation if: the frame crack was cosmetic and non-structural, the damage occurred after the inspection was logged, or the inspector failed to properly document location and severity. You'll need clear evidence—repair records, photos, or an independent frame shop assessment. Equipment findings are harder to dispute than missing paperwork, so gather physical evidence immediately and submit your challenge with supporting documentation.

Texas leads by a wide margin. In the last 180 days, our records show Texas with 483 citations, followed by New Mexico with 79 citations and Iowa with 43 citations. Texas accounted for roughly 61% of all 393.207B citations in that period. The OOS rate varies significantly: Texas placed 43.5% of cited trucks out of service, New Mexico 60.8%, and Iowa 72.1%. If you operate in Iowa, you face a higher OOS risk—nearly 3 in 4 citations result in an out-of-service order. Texas inspectors are slightly more lenient but still cite frequently, likely due to high traffic volume and wear on older equipment.

Fix it immediately. In the last 90 days alone, we recorded 301 citations for cracked frames, with over half resulting in OOS orders. Monthly citation volume has been climbing—January and February 2026 saw 140 and 128 citations respectively. If you were not placed out of service initially, you're still at high risk of an OOS order at the next inspection. A cracked frame worsens over time due to stress and load, and continued operation can lead to catastrophic failure, brake system loss, or steering failure. Schedule repairs with a certified frame shop within 48 hours. Most carriers require frame repairs to be completed and re-inspected before returning to revenue service.

Both. This violation impacts your driver record and your carrier's safety profile. FMCSA tracks frame defects under the Vehicle Maintenance and Unsafe Vehicle BASICs, which are assigned to the carrier's DOT number. However, the citation is also tied to your driver record, which can affect future employment, insurance, and your own CSA rating if you're operating as an independent owner-operator. If you're a company driver, the violation primarily affects your carrier's CSA score, but repeated citations can result in the carrier being placed on Safety Management monitoring. For owner-operators, the violation goes directly to your business record.
