The process includes determining whether a speed of the tractor meets a predetermined condition relative to a predetermined speed. The process further includes monitoring, after determining that the speed of the tractor meets the predetermined condition relative to the predetermined speed, for an activation command to activate a parking brake on the trailer. The process further includes deactivating the trailer parking brake status indicator responsive to the activation command.
