Little is known on the incidence of both the overloading and speeding of heavy vehicles. The analysis of the data in this work concentrated on the two vehicle types that represented the largest number of observation: two axle rigid vehicle and six axle articulated vehicle. In general the following conclusion can be made from this study: there were modest changes in compliance to speeding and mass rules over time; speeding by drivers of 6-axle articulated vehicles) appeared to be relatively constant over the 24 hour period; speeding by drivers of class 3 vehicles was higher during the daylight hours; the overloading of class 9 vehicles were detected to peak between noon and 6 pm; the overloading of class 3 vehicles were detected to be relatively constant during the daylight hours. This could be attributed to the higher use of these vehicles during these hours; the aggregated data may mask the situation in different States; as the states/territories control/implement enforcement activities, further jurisdiction-based analysis could identify these trends.
