Abstract
A traffic control device for use on school buses which locates the traffic control sign in the normal field of view of oncoming traffic, yet is robust, can be extended and retracted automatically and rapidly, and substantially does not suffer wind, acceleration or deceleration damage during movement of the school bus. The traffic control device is comprised of a traffic control display such as a stop sign, apparatus for supporting the display in a horizontal plane adjacent the vehicle, and apparatus for thrusting the display outwardly from the side of the vehicle while rotating the display through 90.degree. to change the facing direction of the display to a plane visible to the traffic. The supporting apparatus is comprised of a beam, the display being fixed to the end of the beam. The rotating apparatus is comprised of the apparatus for thrusting the beam outwardly from the vehicle whereby the display is rotated through 90.degree. while being moved from a position adjacent the vehicle to a position in the direct line of sight of drivers of oncoming traffic.
