Iowa follows a modified comparative fault rule, so you can still recover compensation in a Des Moines personal injury case even if you were partly to blame, as long as your share of fault is not greater than the combined fault of the other parties. Your award is reduced by your percentage of fault. If you are found more than 50 percent responsible, you generally cannot recover damages at all.
Many injured people assume that any share of blame ends their claim. That is not how Iowa law works, but the percentage of fault assigned to you can make a large difference to what you receive, which is why insurers and defense lawyers often work hard to shift blame onto the injured person. If you were hurt because of someone else’s negligence but may have contributed to the accident, visit this website to speak with a personal injury attorney who can evaluate your options.
This article explains the rule in plain terms. It is general information, not legal advice; the outcome of any claim depends on its specific facts.
How Comparative Negligence Works in Iowa
Comparative negligence (Iowa’s statute calls it comparative fault) is a way of dividing responsibility for an accident among everyone who contributed to it. Iowa’s rule is set out in the state’s Comparative Fault Act, Chapter 668 of the Iowa Code. In practice, a jury or judge looks at the evidence and assigns each party a percentage of fault, and the injured person’s damages are adjusted accordingly.
The key points are:
- Fault is shared, not all-or-nothing. Each party, including the injured person, can be assigned a percentage of responsibility.
- Your damages are reduced by your share. If your total damages are $100,000 and you are found 20 percent at fault, your recovery is reduced by 20 percent.
- The 50 percent bar. You are barred from recovery if your fault is greater than the combined fault of the defendants and other parties to whom fault is assigned. Being exactly 50 percent at fault still allows a reduced recovery; being 51 percent at fault does not.
Comparative Negligence Systems Compared
States handle shared fault in different ways. Seeing the alternatives makes Iowa’s approach easier to understand:
| System | How it works | Effect if you are 30% at fault | Effect if you are 60% at fault |
|---|---|---|---|
| Pure contributory negligence | Any fault by the injured person bars recovery | No recovery | No recovery |
| Pure comparative negligence | Recovery reduced by your share, at any level of fault | Award reduced by 30% | Award reduced by 60% |
| Modified comparative (Iowa) | Recovery reduced by your share; barred if your fault is greater than the other parties’ combined fault | Award reduced by 30% | No recovery |
Worked Examples
These simplified examples show how the math works. Real cases involve disputed evidence, multiple defendants and other legal issues, so treat them as illustrations only.
- Rear-end crash with a broken taillight. A driver is rear-ended at a Des Moines intersection. The jury finds the following driver 80 percent at fault for following too closely and the injured driver 20 percent at fault for a non-working brake light. With $50,000 in damages, the injured driver could recover $40,000.
- Even split. In a parking-lot collision where both drivers were looking at their phones, the jury assigns 50 percent fault to each. The injured driver’s $30,000 in damages is reduced to $15,000, but recovery is still allowed.
- Majority at fault. A pedestrian crosses mid-block against a signal at night in dark clothing and is struck by a driver who was slightly speeding. If the pedestrian is found 60 percent at fault, Iowa’s modified rule generally bars any recovery from the driver.
Personal Injury Cases Affected by Comparative Negligence
Comparative fault can come up in almost any type of personal injury claim. It is especially common in these three:
Motor vehicle accidents
Car, truck and motorcycle crashes often involve more than one contributing factor: speeding, distraction, failure to yield, poor weather driving or equipment problems. Insurers routinely review every driver’s conduct to argue that the injured person shares the blame, for example by pointing to a missed turn signal, a few miles per hour over the limit or not wearing a seat belt.
Slip and fall accidents
Property owners can be liable when someone is hurt on their premises because of a dangerous condition they knew or should have known about. In defending these cases, owners and their insurers often argue that the injured person was partly at fault. Common arguments include that the hazard was obvious, that warning signs were ignored, that the person was not watching where they walked, was wearing unsuitable footwear, or was somewhere they were not permitted to be. If those arguments succeed, the victim’s injury award is reduced by the share of fault assigned to them.
Defective products
Manufacturers and distributors have a duty to sell reasonably safe products. If a defective product injures you, you may be able to bring a claim against the manufacturer, distributor or seller. Comparative fault often enters these cases when the company argues that you modified the product, ignored the instructions or warnings, or used it in a way it was not intended for.
How Fault Is Determined
There is no formula for assigning percentages. Insurance adjusters estimate fault during settlement negotiations, and if the case goes to trial, the jury decides based on the evidence. Factors that commonly influence the outcome include:
- Traffic laws or safety rules each party followed or broke.
- Physical evidence such as vehicle damage, skid marks or the condition of a floor or staircase.
- Witness testimony and any video footage.
- Statements made after the accident, including to insurers.
- Expert opinions, such as accident reconstruction or product engineering analysis.
Building a Strong Personal Injury Case
Because every percentage point of fault affects your recovery, evidence matters from the first day. You need to show the other party’s negligence clearly and limit any argument that you contributed to the accident. The evidence that matters most depends on the type of case:
- Motor vehicle accidents: police reports, crash scene photos and videos, eyewitness statements, accident reconstruction diagrams and dashcam footage.
- Slip and fall cases: incident reports, photos of the hazard and lighting, the footwear you were wearing, eyewitness testimony and records of past accidents or complaints on the property.
- Defective product cases: the product itself, photos of the defect, product testing reports, packaging and instructions, purchase records, incident footage and medical records.
Steps to take after an accident
- Get medical care promptly and follow your treatment plan; gaps in treatment are often used to question injuries.
- Report the incident to the police, the property owner or the store as appropriate, and ask for a copy of any report.
- Photograph the scene, the hazard, vehicles and your injuries.
- Collect names and contact details of witnesses.
- Keep damaged property, products and clothing in their current condition.
- Avoid admitting fault or guessing about what happened when speaking to insurers.
- Keep records of medical bills, lost wages and other expenses.
- Speak with a personal injury attorney before giving a recorded statement or accepting a settlement.
Common Mistakes That Increase Your Share of Fault
- Apologizing or saying “it was my fault” at the scene, which may be used later as an admission.
- Posting about the accident or your activities on social media.
- Delaying medical treatment, which can be framed as evidence that you were not seriously hurt.
- Giving a detailed recorded statement to the other party’s insurer without advice.
- Missing deadlines. Iowa generally gives injured people two years from the date of injury to file most personal injury lawsuits, though exceptions apply, so check your deadline with a lawyer early.
Why Legal Help Matters in Shared-Fault Cases
Comparative fault arguments are one of the main ways insurers reduce payouts. An experienced attorney can investigate the accident, preserve evidence, work with experts, calculate the full value of your damages and push back on attempts to inflate your share of the blame. Because the difference between 45 and 55 percent fault can mean the difference between a reduced recovery and none at all, those details can decide the case. Many personal injury lawyers offer a free initial consultation, so it costs little to understand where you stand.
Bottom Line
Being partly at fault does not automatically end a Des Moines personal injury case. Under Iowa’s modified comparative fault rule, you can recover as long as your fault is not greater than that of the other parties, with your award reduced by your percentage. Protect your claim by gathering evidence early, being careful what you say and getting legal advice before dealing with insurers.
