Highlighted cells differ. "Per permit" means the state sets the rule on the permit rather than publishing a fixed limit. Escort triggers are the width or height above which the requirement applies.
FreightDeck applies every state's rules on the route and estimates permits, escorts, police, route surveys, engineering and the truck rate for your exact load.
