Pelvic fractures occurred in 1,198 individuals (0.7%), with 78% having one fracture and 22% having multiple fractures.

From 1 July 2013 all new School Buses in Australia must be fitted with a Child Safety Alarm system hardwired from the vehicle ignition circuit and powered from the vehicle battery. The system must activate after no more than five minutes of operation or immediately once the passenger door has been opened or closed, cannot be overridden by the operator, and can only be deactivated after the disabling switch is actioned. The disabling switch must be located inside the vehicle behind the rearmost passenger seats requiring the driver to walk to the rear to deactivate it. An audible alarm must sound when the engine ignition switch is turned off and the disabling switch has not been actioned, and must be audible from up to 10 metres distance.

Proposal to account for vehicles of category X and to extend its application to vehicles without driver and manual driving controls. New sections introduce definitions for Automated Driving System features (ADSF-1 and ADSF-2) and establish requirements for door closure warning systems and locking devices for vehicles equipped with ADSF-2. Vehicles of category Y are excluded from scope. Various paragraphs are amended regarding door systems, locking mechanisms, and impact definitions to address automated driving scenarios.
