Colorado Comparative Negligence Laws

Updated October 13, 2026 · 2 min read · 2 sources

Short answer

Colorado follows modified comparative negligence (50% bar). You can recover only if your share of fault is less than 50%. At 50% or more you recover nothing, and below that your award is reduced by your percentage of fault.

If you were partly responsible for your own accident, Colorado law decides whether you can still recover, and how much.

Question Answer
Rule Modified comparative negligence (50% bar)
Legal source Colo. Rev. Stat. § 13-21-111
Effect on your recovery You can recover only if your share of fault is less than 50%. At 50% or more you recover nothing, and below that your award is reduced by your percentage of fault.

Example: $100,000 in damages

Here is how the Colorado rule would generally apply if a jury found $100,000 in total damages:

Your share of fault What you could recover
10% $90,000
50% $0
60% $0

Real cases are more complicated: there may be several defendants, insurance limits, or special rules for certain claims.

The five fault systems in the U.S.

  • Contributory negligence: any fault by the injured person bars recovery. Only a few jurisdictions still use it.
  • Pure comparative negligence: recovery is reduced by your share of fault, at any percentage.
  • Modified comparative negligence, 50% bar: you recover only if you were less than 50% at fault.
  • Modified comparative negligence, 51% bar: you recover only if you were not more at fault than the other side.
  • Slight/gross comparison: used in South Dakota; you recover only if your negligence was slight in comparison.

What this means for your claim

Insurance adjusters often argue that the injured person shares the blame, because every percentage point lowers the payout. Photos, witness names, police reports and medical records help push back; the car accident checklist shows what to collect at the scene. Deadlines matter too: see the Colorado personal injury statute of limitations. If fault is disputed, a personal injury lawyer can evaluate the evidence before you give a recorded statement.
