Abstract
A portable traffic signalling apparatus of the wheeled trailer type for temporary signalling at a traffic location for controlling the flow of traffic thereat. The apparatus includes a telescoping mast and a telescoping boom carried by the trailer for positioning at the traffic location. The telescoping action is performed without any large bending loads to permit the extended boom carrying a traffic signal to be moved over a traffic lane under traffic conditions after the traffic apparatus is erected alongside of the traffic location. The extended mast may also carry a traffic signal to be viewed by motorists along with the boom suspended traffic signal. The mast and boom can be telescopically collapsed to assume a storage position on the wheeled trailer after the need for traffic control has been eliminated to allow the trailer to be hauled to another location.
