A crash with a loaded semi isn't a bigger version of a fender bender. The truck can weigh tens of thousands of pounds more than the car it hits, and the company behind it carries far more insurance than any private driver. A separate set of federal safety rules also governs how that truck was supposed to be operated. All of it changes what an Iowa truck claim is worth and how you prove it.
Iowa recorded 52,680 reported crashes statewide in 2025, and 3,824 in June 2026 alone.12 Only a share of those involve commercial trucks, but those are the ones that tend to cause the worst injuries and the largest claims. Here is what Iowa law actually says about the money.
The insurance floor is federal, and it's high
For a passenger car, Iowa requires liability limits of just 20/40/15: $20,000 for injury to one person, $40,000 per accident, and $15,000 for property damage.3 For a private at-fault driver, that's often the ceiling on what you can collect.
Interstate trucking runs on a much larger number. Federal law requires a for-hire carrier hauling ordinary freight in a vehicle rated at 10,001 pounds or more to carry at least $750,000 in liability coverage.4 Carriers moving oil or certain hazardous materials must carry $1 million, and those hauling the most dangerous hazardous substances must carry $5 million.4 Iowa requires its intrastate for-hire carriers to meet the same federal standards. A settlement isn't limited to those figures, but available coverage sets the practical ceiling in most cases, and $750,000 buys a very different result than $20,000.
More defendants usually means more money
In a car wreck you usually have one driver and one policy. A truck crash often has a chain of businesses behind the wheel: the driver, the motor carrier that employed or contracted the driver, sometimes a freight broker, the shipper that loaded the trailer, or a separate company responsible for maintenance. Each can be a defendant, and each may bring its own coverage.
Iowa's fault rules decide how much each one owes. A defendant found to bear less than 50% of the total fault is only severally liable, so it pays only its own share.5 A defendant found 50% or more at fault is jointly and severally liable for your economic damages, which means that if the trucking company is the main wrongdoer, you can collect all of your medical bills and lost wages from it even when a thinly insured co-defendant can't cover its piece.5 That distinction matters when one defendant holds the deep policy and another holds almost nothing.
Federal safety violations become evidence of value
Truck drivers and carriers have to follow the Federal Motor Carrier Safety Regulations, and a violation is often the heart of a strong claim. The hours-of-service rules limit a property-carrying driver to 11 hours of driving after 10 hours off duty, inside a 14-hour on-duty window, with a required 30-minute break and weekly caps of 60 hours in 7 days or 70 in 8.6 Most trucks now log this automatically with an electronic logging device, so the record either supports the driver's account or contradicts it.6
When a log shows the driver was over hours, or a maintenance file shows a brake defect went ignored, the case stops being a simple question of who had the green light. That kind of evidence pushes settlement value up. It's also why getting a lawyer involved quickly matters, because electronic and maintenance records can be overwritten if nobody demands that the carrier preserve them.
Comparative fault can shrink or erase the payout
Iowa uses modified comparative fault. You can still recover as long as your share of the fault is not greater than the combined fault of everyone you're suing, and your damages are then reduced by your own percentage.7 If a jury sets your damages at $500,000 and assigns you 20% of the blame, you collect $400,000. Cross the line, and once your fault is greater than the defendants' combined fault, you recover nothing.7 Carriers and their insurers know this, so expect them to argue that you helped cause the crash. Pinning the fault on the driver and the carrier is often the whole case.
What you can actually collect
Iowa doesn't cap damages in an ordinary truck injury claim. The state's $250,000 noneconomic cap applies only to medical malpractice claims against health care providers, not to an at-fault trucker or trucking company.8 Your economic damages (current and future medical care, plus lost earning capacity) and your noneconomic damages (physical pain and the loss of a normal life) are limited by the evidence and the coverage. No statutory number caps them.
Punitive damages are where Iowa quietly favors truck victims. To win them, you need clear and convincing proof that the conduct was a willful and wanton disregard for the safety of others.9 In an ordinary case, if that conduct wasn't aimed specifically at you, Iowa can route up to 75% of a punitive award into a state fund and leave you with as little as 25%.9 The statute carves out crashes involving a commercial motor vehicle: when the claim is part of a civil action involving the operation of a commercial vehicle, which a semi is, you keep the full punitive award.9
If a bar or restaurant over-served the trucker, Iowa's Dram Shop Act adds a separate claim against the establishment when it served alcohol directly to someone who was visibly intoxicated at the time of the sale.10 Noneconomic damages on that dram shop claim are capped at $250,000 unless the injury involves substantial or permanent impairment, disfigurement, or death.10
Deadlines that can end a claim
You generally have two years from the date of the crash to file a personal injury or wrongful death lawsuit in Iowa.11 A claim for vehicle or other property damage gets five years.11 Miss the two-year window on the injury side and the strength of your case stops mattering. Because the physical and electronic evidence disappears well before then, the practical deadline is much shorter than two years.
Don't overlook your own policy either. Every Iowa auto liability policy includes uninsured and underinsured motorist coverage unless you signed a separate written rejection, so if the truck's coverage falls short of your losses, your UM/UIM may cover part of the gap.12
Given the injuries and the number of corporate defendants, a truck claim is usually reason enough to talk with a lawyer, and you can find one through the thatcarhitme.com legal directory. For the police report itself, see our Iowa crash report guide. If your vehicle also lost resale value, our Iowa diminished value page covers that separate claim.
