Yes, auto insurance is mandatory in Ohio. Ohio law requires all drivers to have a minimum amount of liability insurance coverage. This coverage helps protect drivers financially in case they cause an accident that results in property damage or injury to others. The minimum liability coverage required in Ohio is 25/50/25. This means that drivers must have at least $25,000 in bodily injury liability coverage per person, $50,000 in bodily injury liability coverage per accident, and $25,000 in property damage liability coverage. These minimum coverage amounts are meant to ensure that drivers have some level of financial protection in case of an accident. It's important to note that these are just the minimum requirements, and drivers may choose to purchase additional coverage for added protection. Failure to have the required auto insurance coverage in Ohio can result in penalties, including fines, license suspension, and vehicle impoundment. It's always a good idea to consult with an insurance professional to determine the best coverage options for your specific needs and budget.
