In studies and in anecdotal evidence a relationship between vibration in heavy vehicles and driver fatigue has been assumed, without supporting evidence. A literature review identified a few studies showing a possible association between fatigue and low frequency vibration that is typical of the vibration frequencies experienced by heavy vehicle drivers. An experimental study would be needed to determine whether the effect of vibration would be noticeable among known contributors to fatigue (eg, time awake, time on task, rest and sleep, circadian factors). Research has also associated whole body vibration exposure with adverse health effects on the human body. Limited available data suggests that exposure to vibration of Australian heavy vehicle drivers may be high, putting drivers at risk to health. A field study of vibration levels experienced by Australian truck drivers would be necessary to determine actual vibration exposure levels and establish standards for trucks sold in Australia.
