A truck crash isn't a bigger car crash. When a loaded tractor-trailer meets a passenger car, the physics are lopsided, and so are the injuries. Idaho's own records make the point. In 2024 the Idaho Transportation Department counted 2,897 crashes involving commercial motor vehicles, 42 of them fatal, and 50 people were killed.1 Of those 50 deaths, 88% were people in cars, pickups, vans, or on foot, not anyone riding in the truck.1 The state put the economic cost of commercial-vehicle crashes that year near $911 million.1
If you're trying to learn what your case is "worth," there's no Idaho average to hand you, and anyone who quotes one is guessing. A settlement gets built from your actual losses, then run through a short list of Idaho rules that either raise the number or cut it off. Those rules, not a formula, decide the amount here.
The deadline that can erase the case
In Idaho you generally have two years from the date of the crash to file a personal injury lawsuit. That comes from Idaho Code 5-219(4), which covers both injury claims and wrongful death.2 A wrongful death claim runs two years from the date of death, and when the injured person is a minor, the clock is paused until they turn 18.2
Miss the deadline and the value of your claim drops to zero, no matter how badly you were hurt. The closer you drift toward that two-year mark without filing, the less reason an insurer has to offer you a fair number. Damage to the vehicle itself has a longer window. Idaho gives you three years for injury to property, including your car, under Idaho Code 5-218(3).3
How fault splits the money
Idaho uses modified comparative negligence, and the exact wording matters. Under Idaho Code 6-801 you can recover only if your share of the fault was "not as great as" the other side's.4 Read it literally: at a 50/50 split, you get nothing. You have to be less at fault than the trucker or the trucking company to collect at all, and whatever you do recover is cut by your own percentage.4
So if your damages come to $400,000 and you're assigned 20% of the blame, you're looking at $320,000. Trucking companies and their insurers know this rule cold, and pushing 10 or 15 points of fault onto you is one of the first moves they make. It's also why the small facts decide these cases. A driver who was texting was breaking Idaho's handheld ban under Idaho Code 49-1401A, and a traffic violation like that is strong evidence of fault.5 The crash report, the truck's electronic logs, and the driver's record usually settle the fault question long before a check gets written.
What you can actually collect
Idaho sorts damages into two buckets. Economic damages, the hard costs, are not capped in an ordinary crash case. That covers your medical bills, future medical care, lost wages, lost earning capacity, and vehicle damage, and in a serious truck wreck those numbers climb fast.
Noneconomic damages, meaning pain, suffering, and the loss of things you used to be able to do, are capped. For the year that began July 1, 2026 the ceiling is $538,425.04, a figure the Idaho Industrial Commission recalculates every July 1 to track wage growth under Idaho Code 6-1603.67 It was $509,013.28 the year before, so the number does move.7
One exception comes up in truck cases more than most. The cap doesn't apply at all when the harm came from willful or reckless misconduct, or from conduct a jury finds beyond a reasonable doubt would be a felony.6 A driver who falsified logbooks, drove drunk, or ran well past the federal hours-of-service limits can push a case into that zone, and there the pain-and-suffering award has no ceiling.
Punitive damages sit in a separate, harder category. Idaho Code 6-1604 requires clear and convincing evidence of oppressive, fraudulent, malicious, or outrageous conduct, and caps any punitive award at the greater of $250,000 or three times the compensatory damages.8 If a bar over-served the driver, Idaho's dram shop law lets you bring a narrow claim, but only when the driver was underage or obviously intoxicated when served, and only if you send written notice by certified mail within 180 days under Idaho Code 23-808.9
Why a truck policy is deeper than a car policy
Here is where truck cases pull away from ordinary fender-benders. An Idaho driver only has to carry 25/50/15 in liability coverage: $25,000 per person, $50,000 per crash, and $15,000 for property damage.10 For a catastrophic injury, that isn't close to enough.
Interstate trucks live under different rules. Federal law at 49 CFR 387.9 requires most freight carriers to hold at least $750,000 in liability coverage, rising to $1,000,000 for oil and many hazardous materials and $5,000,000 for the most dangerous cargo hauled in bulk.11 That deeper pool is often the real reason a truck settlement can reach numbers a personal auto policy never could.
The company behind the truck usually matters more than the driver. A motor carrier is generally responsible for the drivers it puts on the road, and federal safety rules hand you evidence. The hours-of-service limits in 49 CFR 395.3 hold a property-carrying driver to no more than 11 hours of driving, inside a 14-hour on-duty window, after 10 hours off.12 When a crash traces back to a tired driver, the logs, the dispatch records, and the maintenance file become the evidence the case turns on.
Don't overlook your own policy. Idaho requires insurers to include uninsured and underinsured motorist coverage on every auto policy unless you rejected it in writing, under Idaho Code 41-2502.13 If the trucker turns out to be underinsured for the harm they caused, or drives off, your UM/UIM coverage can be what actually pays.
Putting a number on it
Stack those pieces together and you can see why two Idaho truck cases with similar injuries settle for very different amounts. A low-speed crash with a driver who fully recovered and a cooperative carrier might resolve for the medical bills plus a modest pain-and-suffering figure. A permanent injury caused by a fatigued or impaired driver, where the noneconomic cap comes off and a $750,000 or larger federal policy is in play, is a different case entirely. What moves the number is everything above: the strength of the fault evidence, whether the conduct was reckless, the size of the coverage, and how much of your loss is hard economic damage a cap can't touch.
Vehicle damage and the report
A commercial-vehicle wreck often totals or badly damages your car, and even a well-repaired vehicle loses resale value afterward. Idaho recognizes that loss, and you can read how to pursue it on the Idaho diminished value page. You'll also want the official crash report for your file, which is covered on the Idaho crash reports page.
Truck cases move fast on the defense side. Carriers send investigators to the scene within hours, and electronic logs and telematics can be overwritten. If your injuries are serious, getting your own record together early is worth more than any settlement calculator. When you're ready to talk it through, you can find an attorney who handles Idaho truck claims.
