Federal Trucking Regulations Behind the Case

The Federal Motor Carrier Safety Regulations, enforced by the Federal Motor Carrier Safety Administration, govern how carriers operate, how drivers get qualified, how vehicles get maintained, and how cargo gets secured. When a carrier or driver violates these regulations and the violation contributes to a crash, the violation becomes evidence of negligence on its own. Driver qualification files matter first: 49 CFR Part 391 requires files documenting a driver’s medical fitness, driving history, road test certification, and employment background, and missing or incomplete files can point to negligent hiring. Vehicle inspection and maintenance records matter too, since 49 CFR Part 396 requires systematic inspections and detailed records, and when brake failure, tire blowouts, or lighting defects cause a crash, these records show whether the carrier kept the vehicle in safe operating condition. Hours-of-service data is its own category: 49 CFR Part 395 limits how long a driver can operate before mandatory rest, violations point directly to fatigue, and electronic logging data is the primary way to establish them. Drug and alcohol testing records carry weight as well, since 49 CFR Part 382 requires pre-employment, random, post-accident, and cause-based testing, and a failure to test, or a failure to act on a positive result, can create carrier liability. Cargo securement rounds out the list, since 49 CFR Part 393 governs how loads must be secured, and improperly loaded or unsecured cargo can shift during transit and cause rollovers, spills, or loss-of-load crashes.

Driver Fatigue in Truck Accidents

Driver fatigue is one of the leading causes of catastrophic truck crashes. Hours-of-service rules exist to prevent it, but violations remain common because of carrier pressure, per-mile pay structures, and unrealistic delivery schedules. The current rules for property-carrying drivers limit driving to 11 hours after 10 consecutive hours off duty, cap the on-duty window at 14 consecutive hours, require a 30-minute break after 8 hours of driving, and cap weekly driving at 60 hours in 7 days or 70 hours in 8 days, with a 34-hour restart available to reset the weekly clock.

After a crash, electronic logging data is the most direct evidence of hours-of-service violations. Our trucking team sends preservation letters on day one so this data is not overwritten once the truck returns to service, and we review dispatch records, load assignments, and scheduling patterns to see whether a violation was an isolated event or a pattern the company tolerated. Research from the Sleep Foundation shows that being awake for 18 consecutive hours produces impairment comparable to a 0.05% blood alcohol level, and 24 hours without sleep matches 0.10%, above the legal limit for any driver. The NHTSA drowsy driving research pages summarize the same impairment risk for long hours awake.

MCS-90 Insurance Endorsement Coverage

Commercial trucking insurance runs on a different framework than a standard auto policy. The MCS-90 endorsement is a federal requirement for for-hire motor carriers operating in interstate commerce, and it guarantees that a minimum level of coverage remains available to injured members of the public regardless of policy exclusions, lapses, or disputes between the carrier and its insurer. Even when a trucking company’s policy has lapsed or been cancelled, or contains exclusions the insurer argues should bar coverage, the MCS-90 endorsement requires the insurer to pay valid claims up to the policy minimum. The insurer can later seek reimbursement from the carrier, but the injured person gets paid first.

Our trucking team routinely identifies and pursues MCS-90 coverage, particularly in cases involving smaller carriers, independent owner-operators, or companies that have tried to reduce their insurance obligations. Identifying the full scope of available coverage is often the difference between a thin settlement offer and one that actually reflects the injury.

Truck Accident Evidence Categories

Truck accident cases turn on records that an ordinary car accident case usually does not have. The work is identifying which records exist, who controls them, and which companies connect to the trip. Electronic logging device data, engine control module downloads, GPS logs, dash camera footage, and telematics records can show speed, braking, duty status, location, and the truck’s movement before impact. Accident reconstruction records, photographs, measurements, debris patterns, gouge marks, fluid trails, and final rest positions can explain the collision sequence. Inspection files, repair records, out-of-service history, tire records, brake work, and trailer ownership can show whether the truck should have been on the road. Safety ratings, prior inspection results, hiring records, training records, and hours-of-service history can show the carrier’s safety background. Truck cases can also involve the driver, carrier, broker, maintenance provider, cargo loader, shipper, trailer owner, and vehicle manufacturer, each carrying its own insurance policy.

Commercial Vehicle Case Types We Handle

Our trucking team handles jackknife crashes, rollover accidents, wide-turn collisions, underride crashes, tire blowouts, unsecured load accidents, bobtail truck crashes, fatigued driving crashes, DUI and impaired driving crashes, rear-end and head-on truck collisions, blind spot crashes, overweight or overloaded trucks, and multi-vehicle pileups. We also handle cases involving coal trucks, garbage trucks, delivery vans, refrigerated trucks, tanker trucks, flatbed trucks, logging trucks, and other commercial motor vehicles operating on public roads. Some of the most devastating collisions are underride crashes, where a passenger vehicle slides beneath a trailer.

How a Trucking Company Responds After a Crash

After a serious truck accident, the carrier and its insurer usually move fast. They collect statements, inspect the vehicle, gather internal records, and look for facts that reduce their exposure. Response teams may collect photographs, witness statements, repair records, and trip information within hours. Recorded statements can be used against an injured person before the medical picture is even clear, and early settlement offers can arrive before wage loss, future care, and long-term medical needs are known.

Injured people need their own evidence review before the carrier’s version of events becomes the only version. Electronic logging data, dash camera footage, inspection reports, maintenance files, and carrier communications can disappear without a preservation request, which is why our team sends that request as soon as a case begins.

Serious Injuries in Truck Accident Cases

Truck accidents can turn the medical record into the center of the case. Traumatic brain injuries and spinal cord injuries depend on neurology records, imaging, symptoms, and therapy notes. Femur fractures, pelvic fractures, facial fractures, sternum fractures, and burn injuries depend on surgical records, imaging, wound care, and specialist notes. Shoulder, knee, hip, and lower leg injuries depend on orthopedic care, therapy progress, and mobility documentation. When a case involves long-term disability, PTSD, or wrongful death, future-care planning, mental-health records, and family-loss documentation can become part of the file.

Trucking Insurance Layers Beyond the Carrier

A single truck accident can involve more insurance layers than most people expect. The driver may carry a personal auto policy in addition to any coverage tied to the truck. The motor carrier typically carries a primary liability policy, and an owner-operator leased to a carrier may carry a separate policy that applies depending on the lease terms and who controlled the trip at the time of the crash. A freight broker that arranged the load may carry its own liability coverage, and the trailer owner, if different from the tractor owner, may carry coverage tied to the trailer itself. Excess or umbrella coverage can sit above any of these primary policies once the underlying limits are confirmed.

Sorting out which policies actually apply takes a review of the lease agreements, the bill of lading, the dispatch records, and the insurance certificates tied to the trip. A crash caused by a leased owner-operator raises different coverage questions than a crash caused by a company driver in a company-owned truck, and a broker-arranged load raises different questions still. Our trucking team reviews every layer before accepting an insurer’s account of what coverage exists.

Who Gets Hurt When a Truck Crashes

According to NHTSA’s 2023 large truck traffic safety facts, 5,472 people died in crashes involving large trucks nationwide that year, and 70 percent of those killed were occupants of other vehicles rather than the truck itself. The same report found that a majority of fatal large-truck crashes happened on rural roads, with about a quarter occurring on interstates, and that drivers of large trucks involved in fatal crashes carried the second-highest rate of prior recorded crashes among all vehicle types. In Kentucky specifically, FMCSA data recorded 118 commercial motor vehicle fatalities across roughly 48,993 million vehicle miles traveled in 2023, a fatality rate that underscores how much weight and stopping distance separate a loaded tractor-trailer from a passenger car.

Building a Truck Accident Case

Driver qualification files, hours-of-service records, dispatch pressure, maintenance histories, onboard data, broker relationships, trailer ownership, and layered insurance policies all shape the evidence in a truck accident case. The case often changes once the investigation moves beyond the police report, and records may reveal fatigue, delayed maintenance, prior safety violations, or a schedule that pushed a driver too hard. Our dedicated trucking team, led by attorneys who hold membership in the Trucking Trial Lawyers Association Top 10, reviews these records early so the case is built on documents rather than assumptions.
