Are there laws for making payment arrangements for traffic fines in Ohio, and if so what are they?

It's up to the judge's discretion. There is no law requiring them to make payment arrangements, although most will try and be reasonable. It also depends on your behavior. If you fail to pay your taxes and fail to take care of it to the point that you have to go to court, the judge might feel that you've been horsing around long enough and it's time to pay already.
