ABSTRACT. This ractors account for 15% to 45% of work−related fatalities among those employed in agriculture in many industrialized countries including Australia, the U.S., Canada, and New Zealand (Myers et al., 1998;Brison et al., 1998;Langley et al., 1997;Clarke and Coleman, 1995;Day, 1999). Historically, rollover events have comprised the large majority of tractor fatalities. Runover events comprise the next largest proportion of tractor fatalities, and in some areas, runover events now account for a greater proportion of tractor−related deaths than rollovers (Lough and Day, 2001).Development and evaluation of appropriate interventions for tractor runover death and injury has lagged behind that for rollover events, possibly because runover events are not homogenous. At least five major types of runover events have been described in a detailed Australian case series study (table 1) (NOHSC, 2000). Falling from a moving tractor and being run over by the tractor or attached machinery was the most common,
