Once every three years for the thing Ohio actually promises, the 2-point credit against your total.
The three-year interval is the whole rhythm of Ohio's program. Complete an approved course, the BMV applies a 2-point credit, and the option goes dormant until three years pass. Since the credit is modest, the timing question matters more here than in bigger-credit states: a credit taken when you're sitting at 2 points is a credit you can't take eighteen months later when you're sitting at 10 and staring at Ohio's 12-point suspension line. If your record has a habit of collecting points, the credit is worth more later than sooner. If a one-off ticket is genuinely out of character, taking it now is fine; you'll likely never need it again.
Running outside that clock entirely: court arrangements. Where an Ohio court offers to dismiss or reduce a specific ticket in exchange for a course, that's a per-case deal between you and that court, and doing one doesn't consume your 3-year BMV credit. It's also not something you can schedule; it exists where a given court offers it, which is why the first call on any fresh Ohio ticket is to the clerk, not to a course checkout page.
Nothing about frequency changes what the course can't do: the conviction from a paid ticket stays on your record and visible to insurers however often you study.
Pricing is on our cost page, $27.95 to $39 as of August 2026, and every approved online course we track is compared on the Ohio page.
