There are many states where trucks only need one plate, and they put it on the front.
Now the supposed reason is that you might have a trailer attached sometimes. But since most truck drivers rarely ever haul with a trailer, the reason is pointless.
In my experience, white dudes follow this "rule" here and people of color put the plates on the back, you know because cops are racist pigs.
Kentucky for one. I know that cause I dated a cop's daughter out there. Thankfully she decided to go fuck some other dude, so the dad wasn't mad at me.
Kentucky Statutes 186.170 – Display of registration plates, insignia, clearly states
the owner shall have the receipt issued by the cabinet through the county clerk constantly in his possession, and shall display the registration plate conspicuously upon the rear of the motor vehicle...
The law does use the word "his" so maybe it is just men that need to though?
I dunno. Maybe that passed since 2016 when I left. When I left, having a single plate in your windshield was acceptable, provided you were the correct color of skin tone.
Well, yeah. If they don't and are hauling more weight than their plates allow, the highway patrol will give them a ticket. If I wanted to haul over 3 tons of weight with my Tahoe, I'd have to have commercial plates even though it's not being used as a commercial vehicle.
Until fairly recently, all trucks were licensed with the "COMMERCIAL" rated plates in MO... Even the show truck I had in the early 2000'w had to have commercial plates, and the most it ever hauled was detailing equipment.
I for one am tired of tarnishing the good name of pigs by associating them with cops.
Pigs give us ham, and pork, and bacon. Pigs are at the center of every good barbeque. Pigs eat garbage and produce wonderful cuts of meat. Pigs are wonderful, smart creatures and don't deserve to be cast down by permanent association with the worst and dimmest.
Cops are locusts. Inedible, swarming creatures that descend upon decent folk and blight all they touch.
