A Crash Testing Evaluation of Road Signs to Mitigate Vehicle Windscreen Spearing Risk
Fatal incidents have occurred in Queensland and New South Wales involving sight boards spearing through vehicle windscreens. These crashes occurred at T-intersections where the impacting vehicle was travelling at high speed on the continuing carriageway. An innovative research program was undertaken to test various end treatments which could be applied to both new sign designs and existing signs. The research showed that windscreen penetration could be prevented by utilising cost-effective treatments.
