Abstract
A portable traffic control unit comprising a wheeled trailer having a main frame attachable to a towing vehicle. A telescoping, vertical mast carries a pivotally mounted boom assembly. A first traffic control signal is secured to the vertical mast and a second at the end of the horizontal boom. A winch assembly can be actuated to raise the vertical mast and upon the vertical mast reaching its full extension, causing the boom to pivot to a generally horizontal position. In the erected position, the device provides a street side signal and an over-the-road traffic control signal for safety and visibility.
