Impact tests with a car and a passenger coach were carried out on a bridge parapet designed by Messrs. Christiani and Nielsen Limited. The novel feature of the parapet is the design of the posts which pivot about their bases against the resistance of built-in hydraulic shock absorber units. The parapet is intended as an alternative to Group P1 vehicle parapets specified in Ministry of Transport Technical Memorandum (Bridges) No. BE5, which are required to contain a car weighing 1.5Mg striking at 113 km/h and 20 deg; there are no current requirements in respect of heavier vehicles. In these tests the containment and redirection properties of the hydraulic parapet were satisfactory for the car and were better than those of current Group P1 parapets for the heavier vehicle.
