A road safety bollard is in the form of a hollow upstanding body (10) moulded from translucent plastics material and having a tubular stem portion (12) which is self-supporting under normal conditions. The stem has a part (20) near its lower end, conveniently of circular section, which is of bellow or concertina construction so that it will yield on collision or impact with other parts of the bollard to reduce the likelihood of permanent damage thereto. The part may have inherent resilience so that the bollard will tend to spring back to the upright position and/or may have a bending stiffness enabling the bollard to be restored to an upright position manually. |
