Risk factors for a farm vehicle public road crash.

Driver, vehicle, public road, and farm enterprise characteristics were examined for their combined association with farm vehicle public road crash group membership. North Carolina farms experiencing a public road crash from 1992 to 2003 (n=200) were compared with a non-crash control group (n=185) for a 1:1 case:control ratio. Five characteristics were associated with increased odds of crash group membership in the combined model (likelihood ratio=175.95; d.f.=15; p<.001): use of non-English speaking drivers (OR=3.71); use of non-family hired help drivers (OR=4.25); types of non-farm vehicle public road use (OR=1.39); farm injury history (OR=1.33); and, use of younger farm vehicle drivers (OR=1.02). Farms reporting older farm vehicle drivers (OR=0.97), and low farm income (OR=0.29) were less likely crash group members. Recommendations are discussed for incorporating findings into farm vehicle crash prevention research and interventions.
