VEHICLE WEIGHT, FATALITY RISK AND CRASH COMPATIBILITY OF MODEL YEAR 1991-99 PASSENGER CARS AND LIGHT TRUCKS
Logistic regressions calibrate crash fatality rates per billion miles for model year 1991-99 passenger cars, pickup trucks, sport utility vehicles (SUVs) and vans during calendar years 1995-2000 - by vehicle weight, vehicle type, driver age and gender, urban/rural, and other vehicle, driver and environmental factors - a cross-sectional analysis of the fatality rates of existing vehicles. These analyses suggest that, after controlling for driver age/gender, urban/rural, annual mileage, and other factors: (a) The association between vehicle weight and overall crash fatality rates in the heavier Model Year (MY) 1991-99 LTVs (light trucks and vans) was not significant; (b) In three other groups of MY 1991-99 vehicles - the lighter LTVs, the heavier cars, and especially the lighter cars - fatality rates increased as weights decreased; and (c) MY 1996-99 pickup trucks and SUVs had, on the average, higher fatality rates than MY 1996-99 passenger cars or minivans of comparable weight. Logistic regression analyses of fatalities per billion miles in two-vehicle collisions show that MY 1991-99 LTVs were more aggressive than MY 1991-99 cars when they struck other vehicles. The analyses show correlations between occupants' fatality risk in the struck car and the frontal height-of-force and rigidity of the striking LTV.
