Abstract
A traffic bollard mountable to a path surface for providing a barrier to a vehicle moving on the path surface. The bollard includes a stanchion member extending along a longitudinal axis from an upper distal end to a lower proximal end biasedly attachable to the path surface in a normally upright position. The stanchion member is flexible along substantially the entire extent of its longitudinal axis to be resiliently deflectable from its normally upright position upon the bollard being contacted with a predetermined amount of force by the moving vehicle. At least one collar is rotatably mounted about the stanchion member along the longitudinal axis thereof. The collar extends intermediate the distal and proximal ends of the stanchion member and freely rotates about the longitudinal axis thereof upon being contacted by the moving vehicle.
