Minimum Coverage Requirements in Iowa
Iowa operates under a tort liability system and requires all drivers to carry minimum liability coverage of 20/40/15. After a DUI conviction, Iowa law mandates SR-22 filing for 2 years from the conviction date. The Iowa Department of Transportation issues temporary restricted licenses during suspension periods, but eligibility begins 30 days after the suspension start date for first-time offenders.
How Much Does Car Insurance Cost in Iowa?
Iowa post-DUI insurance premiums reflect BAC level at arrest, prior offenses, age, and whether ignition interlock is required. First-offense DUI drivers with BAC under .15 typically see premiums 60–90% higher than standard rates, while second-offense or aggravated DUI cases can see increases of 150–250%.
What Affects Your Rate
- First-offense DUI with BAC .08–.14 increases base premium by 60–90% for 2 years in Iowa.
- Aggravated DUI with BAC .15 or higher triggers 100–150% surcharge and ignition interlock requirement in most Iowa counties.
- Second or subsequent DUI offense within 12 years results in 150–250% premium increase and 2-year minimum IID requirement statewide.
- Age under 25 at time of DUI conviction adds 20–40% to post-DUI premiums due to layered risk factors.
- Cedar Rapids, Des Moines, and Davenport metro drivers pay 15–25% more than rural Iowa drivers due to claim frequency and uninsured motorist collision rates.
- SR-22 filing fee in Iowa is typically $25–$50 one-time, separate from premium increases, and is paid to the carrier at policy inception.
