ABSTRACT:
A portable barricade for use at school crossings, and the like, has a frame mounted on wheels or similar transporter devices, and is provided with at least one lamp assembly for warning parties approaching the barricadeof the presence of a potentially hazardous condition. Attached to the frame is a brake which permits selective retention of the barricade in a desired position in a crosswalk or similar location for a predetermined length of time. Once the need for the barricade at the particular location has ended, the brake may be easily released and the frame moved to another location.
