Heavy Vehicles
Driver errors resulting from speed, drink driving and fatigue all contribute to truck crashes.
inappropriate speeds uncontrolled movements and turns, especially at intersections and access points lack of separation of vehicles or road users of different size (e.g. lack of facilities for pedestrians and cyclists) lack of separation for vehicles travelling in different directions (e.g. lack of median barriers) tight radius turns long steep grades in conjunction with overloading contributing to brake failure seasonal agricultural vehicles using or crossing trunk roads in rural areas lack of advanced warning of hazards inadequate information to enable road users to negotiate the roadway safely presence of hazards, particularly at the roadside (e.g. utility poles and trees) poor road surface.
