This study by the Australian Institute of Criminology examined the circumstances surrounding speeding by heavy vehicles in the Territory of New South Wales for the period 2003 through 2011.
Findings from the study of heavy vehicle speeding in New South Wales (NSW) include the following: between 2003 and 2011, 12,107 heavy vehicles were issued at least 1 strike for speeding, with 3 percent of them receiving 3 or more strikes; a strong relationship was found between vehicles that received 3 or more strikes and speeding at night, with 36 percent of the 3 or more strikes occurring between midnight and 6:00 a.m.; 35 percent of vehicles caught speeding were in zones with posted speed limits of at least 90 km/h, with recidivist speeders more likely to be detected in high speed limit zones; vehicles that had received 4 or more strikes were most likely to be detected speeding on highways, as compared to motorways, roads, or streets; and more vehicles registered in NSW (53 percent) received strikes compared to those with interstate registrations (47 percent). The main purpose of the study was to investigate the degree to which heavy vehicle speeding contributes to heavy vehicle crashes. Data for the study were obtained from a review of traffic citations issued during an 8-year period: January 1, 2003 through April 2, 2011. The findings indicate that a reduction in heavy vehicle speeding could lead to a reduction in traffic fatalities. Tables, figures, and references
