An interview survey of 497 drivers of high vehicles was conducted in 1978. Lorry drivers' knowledge of the overall height of the vehicle plus any load being carried at the time was compared with actual height measurements. Although 95 percent of drivers interviewed claimed to know the height of their vehicles, only 185 drivers were accurate to within 3 in. either side of the correct height and 73 drivers were underestimating their vehicles' height by more than 3 in. Lorry drivers' knowledge of road signs relating to low bridges was also investigated. Seventy-two percent of lorry drivers were fully or acceptably correct in their understanding of the road sign 'Headroom at hazard ahead', but only 31 per cent were correct in their understanding of the road sign 'Available width of headroom at hazard'.
