Doing graphics & truck numbers for a tractor trailer and my customer is insisting the numbers on the passenger side need to in reverse order so they scan correctly when he goes through scales. Example: on the driver's side the wheelbase lettering will read "326 WB" and on the passenger side it'll read "BW 623". Not mirrored, just in reverse order. Is this actually a thing or is my customer on crack? He said he got cited once because they didn't scan correctly. I found nothing on a Google search.
