Truck & Semi Accident Claims in Utah

A crash with an 80,000-pound truck isn’t a bigger car accident, it’s a different kind of case.

General information, not legal advice.

More parties can be liable

Beyond the driver, a truck case may involve the trucking company, the vehicle owner, a maintenance contractor, or the company that loaded the cargo. Identifying every responsible party often means more available insurance to cover serious injuries.

Federal rules and time-sensitive evidence

Commercial trucks are governed by federal safety regulations covering driver hours, inspections, and maintenance. Critical evidence, driver logs, electronic data, and the truck itself, can be altered or lost quickly, so it’s important to act fast and, when appropriate, send a preservation request.

Get experienced help early

Trucking insurers move fast to limit exposure after a serious crash. An attorney experienced with Utah truck cases can preserve evidence, identify every liable party, and deal with the commercial insurers while you focus on recovering.

Why truck claims are bigger and harder

A fully loaded semi can weigh twenty times what your car weighs, so the injuries in a truck crash are usually more serious and the medical costs higher. The insurance is bigger too. Federal rules require most interstate carriers to carry at least $750,000 in liability coverage, and far more for hazardous cargo, compared with the $25,000 minimum for a Utah driver. That money is defended aggressively: trucking insurers often send investigators to the scene within hours, before you have left the hospital.

Liability can reach beyond the driver. Depending on the facts, the trucking company, the owner of the trailer, the shipper or the company that loaded the cargo, a maintenance contractor, or the manufacturer of a failed part may share responsibility. Each has its own insurer and its own lawyers. Identifying every responsible party early is one of the main reasons truck cases need an attorney who handles them regularly.

The evidence that disappears

Commercial drivers are limited to 11 hours of driving inside a 14-hour workday, with required breaks and weekly caps, and those hours are recorded by an electronic logging device in the cab. Carriers must keep those records and the supporting documents for six months. The truck’s engine control module stores speed and braking data from the seconds before impact. Dashcam video, dispatch messages, maintenance logs, and drug and alcohol test results all exist on the day of the crash and can legally be discarded on a schedule afterward.

An attorney sends a preservation letter, often called a spoliation letter, that legally obligates the carrier to keep all of it. The sooner that letter goes out, the more of the case survives. Do not give a recorded statement to the carrier’s insurer or sign any authorization they send you in the meantime.

Where Utah truck crashes happen

Utah is a freight corridor. I-15 carries trucks the length of the state, I-80 climbs Parleys Canyon and crosses the salt flats, I-70 and US-6 through Spanish Fork Canyon mix grades, curves, and winter weather with heavy commercial traffic. The Utah Highway Patrol investigates most of these crashes, and its commercial vehicle findings, including any citations for hours-of-service, weight, or equipment violations, become part of the report your attorney will request.
