What 178.255-7 means in plain language

FMCSR 178.255-7 falls under the hazardous materials transportation rules. This regulation governs specific requirements for how hazardous cargo must be prepared, packaged, or handled during transport. The violation typically involves a failure to meet packaging, labeling, or preparation standards for materials classified as hazardous under Department of Transportation guidelines.

If you've been cited for this code, an inspector found that your cargo preparation, packaging integrity, or labeling did not meet the federal standard for that particular class or type of hazardous material. This is distinct from placard violations (which are more common) or loading/unloading errors—this code addresses the condition and readiness of the hazmat shipment itself before it left the shipper or at the point of inspection.

What our enforcement data actually shows

Across our 13 million+ inspection records, FMCSR 178.255-7 is extremely uncommon. Our database shows only 1 citation issued for this code in all-time history, with 0 citations in the last 12 months and 0 in the last 90 days. That single citation was not issued as an out-of-service violation, resulting in a 0.0% out-of-service rate for this code.

By comparison, the average FMCSR code across all hazmat and non-hazmat violations carries a 31.4% out-of-service rate. The fact that 178.255-7 has never resulted in an out-of-service action in our records suggests that when this violation does occur, inspectors typically issue a citation but do not immediately ground the vehicle. This code ranks #2796 out of 3,036 FMCSR codes by citation volume, making it one of the least-cited regulations in the hazmat category.

Who gets cited most

Based on all-time citation data in our database, the cited entity was BARTLEY PUMP PM LLC (USDOT 3084211) with 1 citation. The vehicle involved was a RAM make. Because of the extremely low volume of citations for this code, geographic and carrier patterns are not statistically meaningful. Your citation may well be the second one ever recorded in this dataset.

How severe is this compared to similar codes

Hazmat violations exist on a spectrum of severity. Consider how 178.255-7 stacks up against other packaging and loading rules in the same hazmat category:

177.834A-HMC (General loading/unloading hazmat) has been cited 3,954 times with a 99.2% out-of-service rate—nearly every violation results in immediate vehicle removal from service.

177.834(a) (General loading/unloading hazmat) shows 3,839 citations with a 97.9% out-of-service rate, similarly severe.

172.516(c)(6) (Placard damaged, deteriorated, or obscured) has 1,796 citations but only a 1.6% out-of-service rate, indicating that cosmetic placard defects are typically warned rather than enforced with vehicle removal.

172.602(c)(1) (Maintenance/accessibility of Emergency Response information) has 1,464 citations and a 0.0% out-of-service rate—never resulting in out-of-service action.

Your citation for 178.255-7, with no out-of-service history, falls into the lower-enforcement-action tier, similar to documentation and placard defects rather than the high-severity loading and unloading violations that nearly always result in vehicle impoundment.

How to avoid it

Because 178.255-7 is so rarely cited, the most effective prevention strategy is thorough pre-shipment verification and communication with your shipper or hazmat broker:

  • Verify packaging before loading. Before accepting any hazmat shipment, visually inspect all containers for damage, leaks, or deterioration. Do not load cargo with compromised packaging—refuse it and notify the shipper.

  • Confirm the hazmat classification and documentation. Review the shipping papers and ensure the material class, proper shipping name, and hazard class are clearly stated. Misclassified or mislabeled cargo at the shipper's warehouse is the root cause of this violation.

  • Check that all required labels and markings are present and correct. Before departing, confirm that each package displays the correct hazard class label, proper shipping name label, and any subsidiary hazard labels required by DOT rules. Do not assume the shipper got it right.

  • Understand your specific commodity. If you regularly haul certain hazmat classes (flammable liquids, oxidizers, etc.), familiarize yourself with their packaging requirements. Know whether a drum, carboy, or composite container is compliant for that product.

  • Document the pre-load inspection. Take photos or notes of the condition and labeling of hazmat cargo before you seal the trailer. This creates a record that the shipment was compliant when it left your facility.

  • Communicate with dispatch about hazmat details. Ensure that your company's hazmat coordinator or safety manager flags any unusual shipments or new vendors, since unfamiliar shippers are more likely to prepare cargo incorrectly.

Since this violation is so rare, most drivers will never encounter it. But if you haul hazmat regularly, treating packaging and labeling verification as a critical pre-trip task—equal in importance to checking brakes and lights—will keep you clear of this and similar hazmat violations.
