Uninsured drivers in Ohio
It's illegal to drive in Ohio without proper car insurance or proof of financial responsibility.
Just because it's illegal, of course, doesn't mean drivers don't do it. A recent report from the Insurance Research Council (IRC) estimates that 16 percent of Ohio drivers were uninsured.
No proof of insurance
If you're an Ohio resident who's caught driving without proof of insurance, you'll need to go to court to show that you are insured. If you don't show proof, penalties include a suspended license (90 days for first-time offenders and up to a year for repeats) and you'll need to file an SR-22 form when you reinstate your license (for a fee).
Alternative car insurance options
If you don't want a typical car insurance policy but want to legally drive in Ohio, you can prove your financial responsibility by leaving $30,000 with the state treasurer. If you can't part with $30,000, you can have 2 people vouch for you by cosigning a bond with the state using their real estate as collateral. Together the cosigners must have $60,000 in equity. (Or you can just get car insurance.)
