What makes Ohio different
The point schedule has a genuine zero band, which is unusual and worth knowing. A small enough margin over the limit carries no points at all, and where that band ends depends on whether the posted limit was above or below the threshold the statute uses. Two drivers cited at the same margin, on roads posted differently, can walk away with different point outcomes.
The third feature is procedural and is specific to Ohio: a municipality may operate a mayor court for its own ordinance violations. Whether a citation is heard there or in a municipal or county court changes the procedure, the costs and the options available, and the citation itself is where that is decided.
