In Iowa, car insurance is mandatory. The state law requires all drivers to carry a minimum amount of liability insurance. According to the Iowa Department of Transportation, the minimum liability coverage required for drivers in Iowa is 20/40/15. This means that drivers must have at least $20,000 for bodily injury liability per person, $40,000 for bodily injury liability per accident, and $15,000 for property damage liability. Failure to maintain the required insurance coverage can result in penalties, including fines and license suspension. Therefore, if you live in Iowa and own a car, it is important to ensure that you have the necessary car insurance coverage to comply with the state law.
