On-road speeds just before the default limit was introduced were compared with speeds one and three years later. The numbers of casualty crashes and casualties in the three years before the default limit was introduced were compared with the corresponding numbers in the three years after the default limit came into effect. On roads where the speed limit was reduced from 60 km/h to 50 km/h, average vehicle speeds decreased by 3.8 km/h after three years and casualty crashes fell by 23 per cent. On roads where the speed limit remained at 60 km/h, average vehicle speeds decreased by 2.1 km/h after three years and casualty crashes fell by 16 per cent. | | Report Number | CASR034 | | Publisher | Centre for Automotive Safety Research | | Publisher City | Adelaide | | Sponsor | Department for Transport, Energy and Infrastructure (SA) | | ISBN | 9781920947330 | | ISSN | 1449-2237 | | Page Count | 36 |
