If the Dot or any police agency looks at your truck and see's no wide load mirrors/oversize load signs/ and Dot numbers, they will pull you over for the state/hwy patrol to do a complete check out, could possibly write a ticket for each offense, or possibly tow the trailer and impound the truck. I knew of a semi driver (renegade) that got fined close to $5000 for multiple offenses and his truck impounded. Not saying this will happen, anythings possible today with a police agency.
