Logistic regressions calibrate crash fatality rates per billion miles for model year 1991-99 passenger cars, pickup trucks, 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:​

• The association between vehicle weight and overall crash fatality rates in the heavier MY 1991-99 LTVs (light trucks and vans) was not significant.
• 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.
• 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.
