Do I need to have dot stickers on my truck? I have a f150 and 61/2 X 12 ft trailer that i use to pull my mowers. I live in michigan right on the state line of indiana so I travel into indiana to work to. Some guy pulled me over today and was lecturing me about how I better get some dot stickers on my truck I did not know I had to have them I thought it was just for bigger trucks. I have my class b cdl and physical card already, im just not sure about the dot stickers?
