Iowa law requires minimum auto liability of just 20/40/15 — $20,000 per person for bodily injury, $40,000 per accident, and $15,000 for property damage. These minimums are among the lowest in the U.S. and reflect a floor that no longer matches modern medical or vehicle costs.
In a single moderate accident — say, a two-vehicle collision with one hospitalization — $20,000 per-person and $40,000 per-accident limits can be exhausted almost immediately. When limits exhaust, the driver is personally liable. VKOVR recommends Iowa drivers carry at least 100/300/100 with matching UM/UIM.
Iowa At-Fault with 51% Comparative Negligence
Iowa follows modified comparative negligence at a 51% bar — if found 51% or more at fault, you cannot recover damages from other parties. Below 51% fault, recovery is reduced by your share.
Accurate accident documentation matters. VKOVR advises Iowa drivers on appropriate liability limits calibrated to the 51% framework and Iowa's moderate uninsured-driver rate.
The Iowa UM/UIM Question
Iowa requires insurers to offer UM and UIM coverage, but policyholders may reject them in writing. Roughly 11% of Iowa drivers are uninsured — moderate by national standards but still meaningful. Given the low 20/40/15 liability floor, underinsurance from other drivers is a bigger concern.
VKOVR strongly recommends Iowa drivers carry UM/UIM at 100/300 to match recommended liability. The cost is typically modest relative to the protection provided.
