Out of service is the shortest order in trucking. Three words on a sticker, and the truck does not move until the defect that earned them is fixed. The rule that makes the sticker an order is federal, the officers who apply it in Texas are state, county and city, and the records they leave are the first thing a lawyer asks for after a wreck.
Out of service. The rule gives the words their force. “Authorized personnel shall declare and mark ‘out-of-service’ any motor vehicle or intermodal equipment which by reason of its mechanical condition or loading would likely cause an accident or a breakdown,” and “An ‘Out-of-Service Vehicle’ sticker shall be used to mark vehicles and intermodal equipment ‘out-of-service.’” Then the order: “No motor carrier or intermodal equipment provider shall require or permit any person to operate nor shall any person operate any motor vehicle or intermodal equipment declared and marked ‘out-of-service’ until all repairs required by the ‘out-of-service notice’ have been satisfactorily completed.” Operating includes towing; a vehicle under the sticker “may be towed away by means of a vehicle using a crane or hoist,” which is to say its own wheels do not turn on a public road until the defect is gone (49 CFR 396.9). The sticker has a cousin for the driver. A federal agent “is authorized to order a driver out of service” on finding a violation of the out-of-service criteria, the first of which is that “No driver shall drive after being on duty in excess of the maximum periods permitted by this part,” and no carrier may “Require or permit a driver who has been ordered out of service to operate a commercial motor vehicle until that driver may lawfully do so under the rules in this part” (49 CFR 395.13). The hours themselves are the Logbook. Short of the sticker, the rule leaves one narrow road: a vehicle discovered unsafe while on the highway “may be continued in operation only to the nearest place where repairs can safely be effected,” and only if that “is less hazardous to the public than to permit the vehicle to remain on the highway” (49 CFR 396.7).
Who writes it in Texas. The federal rule names federal agents. Texas gives the same words to its own officers. The Department of Public Safety’s director “shall, after notice and a public hearing, adopt rules regulating” “the safe operation of commercial motor vehicles” (Transportation Code Section 644.051), and the rule that office adopted incorporates the federal safety regulations by reference, among them Parts 390 through 393 and 395 through 397, “as amended through September 1, 2022” (37 Tex. Admin. Code Section 4.11). The department “shall establish procedures, including training, for the certification of municipal police officers, sheriffs, and deputy sheriffs to enforce this chapter,” and the officers eligible include those of “a municipality with a population of 50,000 or more” and of “a municipality any part of which is located in a county bordering the United Mexican States” (Section 644.101). A certified city officer “may stop, enter, or detain on a highway or at a port of entry within the territory of the municipality a motor vehicle that is subject to this chapter,” and whoever detains one “may prohibit the further operation of the vehicle on a highway if the vehicle or operator of the vehicle is in violation of a federal safety regulation or a rule adopted under this chapter” (Section 644.103). The department’s rule says how: “by declaring the vehicle or operator out-of-service using the North American Standard Out-of-Service Criteria as a guideline,” a document the rule names and does not reprint, and the same sentence is written twice, once for state officers and once for “A certified peace officer from an authorized municipality or county” (37 Tex. Admin. Code Section 4.13). That is the authority a city police department used this week on El Paso’s Transmountain Road, after a semi came down the mountain with brakes that police said had failed: inspectors checking “brakes, lights, seatbelts and couplers” and the logbook, with the officer underneath the truck, six certified inspectors for the whole department, a Class C citation of up to five hundred dollars for what they find, and a truck called to move what cannot be fixed on the shoulder (KVIA). The hill, and what the law asks of a truck at the top of it, is The Long Grade.
The count. The order is not rare. In one three-day national inspection drive, the Department of Public Safety “inspected 8,182 commercial motor vehicles,” and “Approximately 23.6 percent (1,938) of the 18-wheelers, buses and other commercial vehicles inspected were placed out of service for a variety of safety violations until appropriate repairs could be made”; “225 drivers were placed out of service”; and “Issues with brakes and defective vehicle lighting were among the most common infractions that led to out-of-service violations” (Texas DPS, July 5, 2017). The federal highway agency’s summary of the national program, about three million inspections a year in the years it tabulated, put it in one sentence: “Almost a quarter of roadside inspections of commercial vehicles result in the vehicle being taken out-of-service (OOS) for a serious violation” (FHWA, Table 5-6). And the federal crash study found brake problems on 29 percent of the large trucks in the crashes it examined, with a truck carrying that factor “170 percent more likely to be coded with the critical reason for a crash” than one without it (FMCSA, Large Truck Crash Causation Study). One truck in four, and the thing most often wrong with it is the thing that stops it. The inspector on the shoulder is the only person between the yard and the crash who looks.
Before the inspector. The duty does not wait for a trooper. Every carrier “must systematically inspect, repair, and maintain” its vehicles, with “Parts and accessories” “in safe and proper operating condition at all times” (49 CFR 396.3); with limited exceptions, “all brakes with which a motor vehicle is equipped must at all times be capable of operating” (49 CFR 393.48); a vehicle “shall not be operated in such a condition as to likely cause an accident or a breakdown of the vehicle” (49 CFR 396.7); and before each trip the driver must “Be satisfied that the motor vehicle is in safe operating condition” (49 CFR 396.13). The sticker is what the system does when those rules were not kept. Inspection is about why they so often are not.
Why the word matters. In court, an out-of-service order is a fact with a date on it. If the truck in the crash had been placed out of service and driven anyway, the rule it broke is the one quoted above, and breaking a federal safety regulation written to protect the people on the road is, unless excused, negligence in itself (Negligence Per Se). If it had been placed out of service for its brakes before, and sent back out with the same brakes, the carrier knew what the brakes did, which is where gross negligence begins. If it had never been stopped at all, the maintenance file carries the question alone. The record is the examination report the rule names, the “out-of-service notice” and the repairs it required, the invoices that lifted the order, and the engine data that shows what the truck did between the sticker and the crash; all of it is in the company’s hands, and the first letter asks that none of it be lost (Spoliation). The rest of what a carrier answers for is on Trucking Company Liability. Out of service moves the question from the driver’s version of the crash to the truck’s own record: what an inspector found, when, and what the company did about it. A truck that never earned the sticker leaves the case about the road. One that earned it and rolled anyway makes it a case about the company.
