Iowa offers some of the cheapest minimum-coverage rates anywhere — around $335 a year — while full coverage averages roughly $1,937, about 28% under the national average. The state follows an at-fault model with a 20/40/15 liability minimum. Here's the coverage you must carry, what Iowans pay, and how to save.
Iowa uses an at-fault (tort) framework with a 20/40/15 liability minimum — one of the lowest anywhere — and no mandated PIP or uninsured-motorist coverage. That helps keep Iowa's minimum-coverage average near $335 among the cheapest in the nation (only Wyoming is lower), while full coverage runs roughly 28% under average. Light traffic and low density hold claims down, though hail and severe storms are a meaningful driver of comprehensive claims. Credit history is a permitted rating factor.

Iowa's calling card is affordability — the lowest minimum cost nationally — but the 20/40/15 floor is thin, and hail makes comprehensive coverage worth holding. Because full coverage isn't much more than the minimum, most drivers should carry it. With credit and location still creating differences between carriers, a quick comparison can pull an already-cheap Iowa premium lower.
Iowa is one of the most affordable states for auto insurance, with some of the cheapest minimum rates anywhere. Carrying full coverage (cheap here) and weighing a few carriers is the best way to stay well-protected at a low price.
