Boise Semi-Truck and 18-Wheeler Accident Lawyers
When a fully loaded semi-truck hits your vehicle, the injuries — and the legal fight that follows — are unlike anything else on the road
A semi-truck carrying a full load can weigh up to 80,000 pounds under federal law. A typical passenger vehicle weighs somewhere between 3,000 and 4,500 pounds. When the two collide at highway speed, the outcome for occupants of the smaller vehicle is often catastrophic — traumatic brain injuries, spinal cord damage, amputations, and deaths that leave families permanently changed. The Treasure Valley’s major freight corridors, particularly I-84 from the Oregon border through Boise to Twin Falls and beyond, carry thousands of semi-trucks every day. When something goes wrong on that corridor, people get hurt badly.
Hepworth Holzer has represented Idaho victims of semi-truck and 18-wheeler crashes for decades. Our results in trucking cases include a $5.00 million judgment in a wrongful death commercial truck collision case, a $4.80 million settlement in a trucking crash case, a $1.92 million settlement, a $1.85 million verdict, a $1.60 million verdict, and a $1.25 million settlement. These are not car accident cases with truck-sized numbers — they are fully litigated commercial trucking matters where we identified every liable party, preserved critical evidence, and fought insurance companies and their defense teams until our clients received what they were owed. If you were injured in a semi-truck crash in Idaho, call our Boise truck accident lawyers today for a free consultation.

Why Semi-Truck Cases Are Different from Other Truck Accident Cases
Not every commercial vehicle crash is the same. A box truck collision in a parking lot is a fundamentally different legal event than a fully loaded semi-truck jackknifing on I-84 at 65 miles per hour. Semi-trucks — also called 18-wheelers, tractor-trailers, or big rigs — are the largest commercial vehicles on public roads. They are governed by the most demanding set of federal regulations in transportation law, and the companies that operate them carry the highest commercial insurance policy limits.
The Federal Motor Carrier Safety Administration (FMCSA) imposes specific rules on long-haul semi-truck operators that do not apply to lighter commercial vehicles. These include the full hours of service framework under 49 CFR Part 395, which limits property-carrying drivers to 11 hours of driving following 10 consecutive hours off duty and prohibits driving beyond a 14-hour window after coming on duty. Long-haul drivers who regularly push the limits of these rules — or whose companies pressure them to do so — are among the most fatigued drivers on any road. Fatigue at the wheel of an 80,000-pound vehicle is not an inconvenience. It is a lethal condition.
Semi-truck drivers are also required to hold a valid Commercial Driver’s License (CDL) with the appropriate endorsements for the type of vehicle and cargo they operate. Tanker endorsements, hazardous materials endorsements, and combination vehicle endorsements each carry their own training and testing requirements. When a company puts an inadequately licensed or undertrained driver behind the wheel of a fully loaded semi-truck on a highway like I-84, the risk created is foreseeable — and when a crash results, the company bears direct liability for that decision.
The Role of Electronic Logging Devices and Black Box Data
Since December 2017, most commercial truck drivers operating in interstate commerce have been required to use Electronic Logging Devices (ELDs) that automatically record driving time, engine hours, vehicle movement, and location data. Before the ELD mandate, drivers recorded their hours on paper logbooks that were notoriously easy to falsify. ELDs made that falsification harder — but not impossible.
In any serious semi-truck crash case, the ELD data is among the first evidence we seek to preserve. Combined with the truck’s Engine Control Module (ECM) — the black box that records speed, braking inputs, throttle position, and other vehicle data in the moments before a crash — ELD records can tell a complete story of what the driver was doing and how long they had been doing it. Discrepancies between ELD records and GPS location data, or between ELD records and fuel purchase receipts, can reveal tampering or falsification.
This data does not last indefinitely. Trucking companies are required to retain ELD records for six months under 49 CFR Part 395, but ECM data can be overwritten in a matter of weeks depending on the system. When you call Hepworth Holzer after a semi-truck crash, one of our first actions is to send a formal spoliation demand requiring the trucking company to preserve all electronic and physical evidence. That demand goes out immediately — because waiting even a few days can mean losing data that cannot be recovered.

Who Is Liable When a Semi-Truck Crashes in Idaho
Semi-truck crashes rarely involve only one liable party. The driver is the obvious starting point, but the legal analysis almost always goes further. The trucking company that employs the driver is responsible for the driver’s conduct under the doctrine of respondeat superior — and may also face direct liability for its own failures in hiring, training, supervising, or maintaining its fleet. For a full breakdown of every party who can be held responsible, see our page on who is liable in an Idaho truck accident.
In semi-truck cases specifically, additional parties frequently come into the liability picture. The owner of the trailer is often a different entity than the owner of the cab. Freight brokers who arranged the load without verifying the carrier’s safety record can face liability. Cargo loaders who improperly secured the freight can be held responsible when shifting cargo causes a crash or a rollover. When a mechanical failure — a brake defect, a tire failure, a coupling problem — contributed to the crash, the manufacturer of the defective component may face product liability.
Identifying all of these parties and pursuing all available insurance policies is one of the most important things an experienced semi-truck accident lawyer does. Federal law requires most semi-trucks operating in interstate commerce to carry at least $750,000 in liability coverage. Many large carriers maintain $1 million or more. When multiple parties are liable, multiple policies may apply, and the total available coverage can be substantially higher than any single policy limit.
Common Causes of Semi-Truck Crashes on Idaho Highways
The causes of semi-truck crashes on Idaho’s major freight corridors are well documented. Driver fatigue is the most common factor in serious long-haul crashes — hours of service violations, falsified logs, and pressure from carriers to meet tight delivery windows all contribute to drivers operating far past the point of safe awareness. For a detailed breakdown of all the causes we investigate, see our page on the common causes of truck accidents in Idaho.
On I-84 specifically, conditions that regularly contribute to semi-truck crashes include the long east-west grades between Boise and Twin Falls where runaway trucks and brake failures occur, the high-wind corridor across the southern Idaho plain that can push lightly loaded trailers off course, winter ice and black ice conditions that extend the already-long stopping distance of a loaded semi to hundreds of feet, and the construction and merge zones near Boise’s east side where speed differentials between trucks and passenger vehicles create dangerous situations.
Speeding is a consistent factor. A fully loaded semi-truck traveling at 65 miles per hour requires roughly 370 feet to stop under ideal conditions — nearly the length of a football field. When speed increases, stopping distance increases exponentially. When road conditions are compromised by ice, rain, or debris, stopping distance increases further. Semi-truck drivers who fail to account for these realities when following other vehicles or approaching slowing traffic create the conditions for catastrophic rear-end collisions and override crashes.
Impaired driving is another documented cause. Commercial drivers are held to a BAC limit of 0.04 percent — half the standard limit for regular drivers. They are subject to mandatory pre-employment, random, post-accident, and reasonable suspicion drug and alcohol testing under 49 CFR Part 382. When a carrier fails to conduct required testing or allows a driver to operate after a positive test, the carrier faces liability that goes beyond ordinary negligence.
Injuries Commonly Caused by Semi-Truck Crashes
The injuries caused by semi-truck collisions reflect the physics involved. When 80,000 pounds meets a passenger vehicle at highway speed, the forces involved are not survivable without serious injury and frequently not survivable at all. The injuries we handle in semi-truck cases include traumatic brain injuries ranging from concussion to severe open head injury, spinal cord injuries causing partial or complete paralysis, herniated and ruptured discs requiring surgery, traumatic amputations, crush injuries to the chest and abdomen, internal organ damage, severe burn injuries when fuel ignites, and wrongful death.
Many of these injuries require ongoing medical care for years or the rest of a victim’s life. Spinal cord injuries, in particular, can require a lifetime of specialized care, adaptive equipment, in-home assistance, and modified living arrangements that cost millions of dollars over a victim’s expected lifetime. Accurately projecting and documenting these future costs — through life care planners, medical experts, and economic analysts — is essential to recovering what a seriously injured victim will actually need. Settling a case before those future costs are fully understood almost always means leaving a significant portion of what you are owed on the table.
What to Do Immediately After a Semi-Truck Crash in Idaho
The steps you take in the hours immediately following a semi-truck crash directly affect both your health and the strength of your legal case. Seek medical care first — do not wait to see if you feel better. Many serious injuries, including traumatic brain injuries and internal bleeding, do not produce obvious symptoms immediately after a crash. A same-day medical evaluation creates a record that connects your injuries to the crash and protects you from insurance company arguments that your injuries were minor or pre-existing.
If you are physically able, document the scene. Photograph the vehicles, the road conditions, the truck’s DOT number and carrier name on the cab door, skid marks, debris fields, and any visible injuries. Get the truck driver’s CDL information and the name of the trucking company and their insurer. Collect witness contact information before people leave the scene.
Do not speak with the trucking company’s insurance adjuster before consulting an attorney. They will call quickly, and they will sound reasonable. Their goal is to gather information they can use to minimize your claim — a recorded statement, an early description of your injuries that understates their severity, or an early settlement offer that closes your claim before the full extent of your damages is known. The answer to any contact from the carrier’s insurer is to call us first.
Contact Hepworth Holzer as soon as possible. We send preservation demands immediately, begin the evidence investigation, and make sure the trucking company cannot destroy, overwrite, or lose the evidence that proves your case.
