The hours of travel an OSOW load can move is regulated in every state. Typically, states will allow loads within a specified size envelope to move 24 hours per day through their state. When loads exceed the specified size envelope, they are restricted in their hours of travel. Hours of travel restrictions are used to limit the travel of OSOW loads during a time where it is determined to be safe to move. All but a few of states allow Saturday travel for loads within a specified dimension and weight envelop. The following maps display the differences in thresholds for loads to move 24 hours per day (loads are able to move all day or night) on Saturdays. States in the N/A category do not allow 24 hours per day travel on Saturdays for any loads over the legal limit in the specified dimension.
