Another you’ll have to deal with…a lot of towns are doing multiple speeds on a road. So, you’re going 35mph and all of a sudden, there is a 25 sign, usually sort of hidden. They’ll nail you for 10 over, which is a big deal.
Or will come up beside you and pace you, while checking your axles and so forth. I was a flatbedder and had them come up beside me to check my straps (laws for that, too) and tarps. Or better yet, will pace you IN FRONT of you, by about a quarter mile. Say, you’re going along and notice a stater seeming to stay at the same distance from you, in front of you. He’s pacing you. If you are going too fast (or too slow, there are tickets for that, too), he’ll then either pull off or fall back, you pass and then he stops you.
Oh, yeah, there are all SORTS of things to foul you up!! When stopped, your paperwork better be in pristine shape!
Oh, and BTW, do you know about the Hours of Service?? Better bone up on that one, too!!
