ABSTRACT: Farm vehicles (FVs) are not primarily designed for road transportation purposes, but often need to share the roads with other motorists. The interference of these large, slow-moving vehicles with the regular traffic can lead to hazardous situations and cause severe crashes. Farm Vehicle Crashes (FVCs)are rare compared to the total number of road crashes, and hence, have been neglected by many. This has been reflected in various aspects including data collection, education, legislation, and prevention. The number of FVCs in the U.S. has been steady over the last decade. This paper conducts a literaturereview to put forth a better understanding of this safety issue from a transportation standpoint. The main goal of this study is to identify the characteristics of FVCs, the unique contributing factors in FVCs, and possible strategies to mitigate the issues involved. It appears that despite their lower frequency, the rate of severe injuries and fatalities in FVCs is significantly higher than the average for all crashes. The percentage of fatal crashes in FVCs can be nearly five times higher than average for all road crashes. Further, it isestimated that FVs are overrepresented in road crashes considering their low exposure on the roads. The crash contributing factors including time-dependent variables, weather and road surface conditions, location, road classification, manner of collision, and driver’s characteristics are discussed based on the result of multiple studies in different states of the U.S. Several unique characteristics of FVCs distinct them from non-farm vehicle crashes which can result from the characteristics of FVs, rural roads, and the nature of farming tasks. Improvements in lighting and marking, equipping farmvehicles with Rollover Protective Structure (ROPS) and seatbelts, educating the public and farmers, and roadway improvements are recommended aspotential safety improvement strategies for mitigating the frequency and severity of FVCs.
