Negligence laws decide how fault affects compensation after an accident. When more than one person contributed to an injury, state law determines whether the injured person can recover damages.
Most states use some form of comparative negligence. A few states still use contributory negligence, which can bar recovery when the injured person shares any fault.
What Is Negligence?
Negligence means a person failed to use reasonable care and caused harm to someone else. Negligence claims often arise after car accidents, slip and falls, property damage, medical injuries, and other personal injury cases.
A plaintiff usually must prove duty, breach, causation, and damages. When the defendant argues the plaintiff also acted carelessly, comparative or contributory negligence rules may affect the final recovery.
Contributory Negligence
Contributory negligence is the strictest rule. Under this system, a plaintiff may recover nothing if the plaintiff contributed to the accident in any way.
This means even 1% fault can bar recovery. The result can be harsh, especially when the defendant caused most of the harm.
The states and jurisdictions that generally follow contributory negligence are:
- Alabama
- Maryland
- North Carolina
- Virginia
- District of Columbia
Some jurisdictions have exceptions. For example, the District of Columbia has a special rule for certain pedestrians and vulnerable road users. A local attorney should review the specific facts before assuming the complete bar applies.
Comparative Negligence
Comparative negligence allows fault to be divided between the parties. The plaintiff’s damages are reduced by the plaintiff’s percentage of fault.
For example, a plaintiff with $100,000 in damages may be found 25% responsible. Under comparative negligence, the recovery may be reduced to $75,000.
Her Lawyer’s guide to comparative negligence explains how fault percentages may affect settlement and trial outcomes.
Pure Comparative Negligence States
Pure comparative negligence allows a plaintiff to recover damages even when the plaintiff is mostly at fault. The award is reduced by the plaintiff’s fault percentage.
For example, a plaintiff who is 80% responsible may still recover 20% of the proven damages.
Pure comparative negligence states include:
- Alaska
- Arizona
- California
- Kentucky
- Louisiana
- Mississippi
- Missouri
- New Mexico
- New York
- Rhode Island
- Washington
California follows pure comparative negligence. This means partial fault reduces damages but does not automatically prevent recovery.
Modified Comparative Negligence
Modified comparative negligence allows recovery only when the plaintiff’s fault stays below a certain threshold. States usually use either a 50% bar or a 51% bar.
Under a 50% bar rule, a plaintiff cannot recover if the plaintiff is 50% or more at fault. Under a 51% bar rule, a plaintiff cannot recover if the plaintiff is more than 50% at fault.
This distinction matters when fault is split evenly. A plaintiff found exactly 50% responsible may recover in a 51% bar state but not in a 50% bar state.
States Using a 50% Bar Rule
A 50% bar rule usually requires the plaintiff to be less responsible than the defendant or defendants.
States using this approach generally include:
- Arkansas
- Colorado
- Georgia
- Idaho
- Kansas
- Maine
- Nebraska
- North Dakota
- Tennessee
- Utah
In these states, a plaintiff found equally responsible may be barred from recovery.
States Using a 51% Bar Rule
A 51% bar rule usually allows recovery when the plaintiff is 50% or less at fault. Recovery is barred when the plaintiff is more than 50% responsible.
States using this approach generally include:
- Connecticut
- Delaware
- Florida
- Hawaii
- Illinois
- Indiana
- Iowa
- Massachusetts
- Michigan
- Minnesota
- Montana
- Nevada
- New Hampshire
- New Jersey
- Ohio
- Oklahoma
- Oregon
- Pennsylvania
- South Carolina
- Texas
- Vermont
- West Virginia
- Wisconsin
- Wyoming
Florida is important to note because older summaries may still list it as a pure comparative negligence state. Florida now generally uses a modified comparative negligence rule for most negligence cases, although medical malpractice has separate treatment.
South Dakota’s Slight-Gross Rule
South Dakota uses a less common negligence rule. A plaintiff may recover only when the plaintiff’s negligence is slight compared with the defendant’s negligence.
The court still reduces damages based on the plaintiff’s share of fault. However, the analysis does not rely only on a fixed 50% or 51% threshold.
Why State Law Matters
The same accident can lead to different results depending on the state. A plaintiff who is 20% at fault may recover in most states. In a contributory negligence state, that same percentage may bar recovery.
A state-by-state negligence review from LawInfo and an updated state negligence laws overview can help identify the general rule. The governing statute or case law should still be checked before relying on a summary.

FAQs About Negligence Laws by State
Which states use contributory negligence?
Alabama, Maryland, North Carolina, Virginia, and the District of Columbia generally use contributory negligence. Exceptions may apply in specific cases.
What type of negligence law does California use?
California uses pure comparative negligence. A plaintiff’s damages are reduced by their percentage of fault.
Does partial fault always prevent recovery?
No. Most states allow partial recovery when the plaintiff shares fault. The result depends on whether the state uses pure comparative, modified comparative, or contributory negligence.
What happens if a plaintiff is 50% at fault?
