I see you live in central Ohio (as do I) are you sure that is law in Ohio?
Nope.
Too many grey areas. Ask a dozen LEO's and you will get a dozen different examples.
There is a big difference of what the laws actually mean, and how they are interpreted and enforced by boots on the ground.
Around here, if your sporting a dually and gooseneck with a tractor or something on it (not the hotshot truckers hauling 3-car wedges)....you get waived through and look at like you are stupid if you pull into a weigh station amongst the 18-wheelers.
BUT, by the letter of the law....I have a 14k GVWR dually. And I can tow a 12k equipment trailer no problem. But upgrade to a 14k and all of the sudden a class A is required. Same trailer towed by dads slightly older dually one ton with its 12k GVWR gets a free pass.
The laws are stupid......at one time no "pickup" truck would exceed the the requirements under normal circumstances. But the never ending war among the big 3 to drive up the tow ratings and GVWR's have made it all but impossible for small-time landscaper-types to comply with the laws. 25 years ago who would have though twice about buying a new 14k trailer to go with their new pickup. OR even splurging and upgrading to 8k axles. But now its is a real concern.
The laws were originally intended to require further driver training to drive a dumptruck, a schoolbus, an 18-wheeler, or a heavy duty straight truck. The laws are long over due to be revised to reflect current "pickup" trucks.
Ohio is not a strict state when it comes to this aspect. But again, all depends on the LEO and their mood for the day and their knowledge of the "letter of the law". But I feel bad for those that live in areas that it has become all about a money grab and targeting the landscape/hardscape crews and companies. Landscape companies cannot (and shouldnt) be required to pay CDL-A wages for their general laborers towing a trailer with a dingo, mowers, a trencher, etc.
