Idaho Head Injury Laws

Idaho at a glance

Idaho allows two years to sue for an injury to the person or for wrongful death.[1] Claims against a political subdivision must be filed within 180 days.[2] A plaintiff can recover only if their negligence was not as great as the defendant’s.[3] Idaho caps noneconomic damages, adjusted each year.[4]

Idaho Code § 5-219(4)

Within two (2) years: … An action to recover damages for professional malpractice, or for an injury to the person, or for the death of one caused by the wrongful act or neglect of another

Shared fault

Idaho Code § 6-801

Contributory negligence or comparative responsibility shall not bar recovery in an action by any person or his legal representative to recover damages for negligence, gross negligence or comparative responsibility resulting in death or in injury to person or property, if such negligence or comparative responsibility was not as great as the negligence, gross negligence or comparative responsibility of the person against whom recovery is sought.

This is modified comparative fault, often called the 50% bar. An injured person whose fault is less than the parties the statute compares them to can recover damages reduced by their share; at 50% or more, recovery is barred.

Damage caps

Idaho Code § 6-1603(1)

In no action seeking damages for personal injury, including death, shall a judgment for noneconomic damages be entered for a claimant exceeding the maximum amount of two hundred fifty thousand dollars ($250,000); provided, however, that beginning on July 1, 2004, and each July 1 thereafter, the cap on noneconomic damages

Because the cap is adjusted every July 1, the current figure is higher than the $250,000 base stated in the statute.[4]

Auto insurance requirements

The Idaho Driver’s Manual states that vehicles “must carry liability insurance providing the following minimum coverage: $25,000 for injury or death of one person; $50,000 for injury or death of two or more people; and $15,000 for property damage.”[5] Idaho is not one of the no-fault states.[6]
