The effectiveness of automatic belts in reducing fatality rates in Toyota Cressidas
1National Center for Statistics and Analysis, National Highway Traffic Safety Administration, Washington, D.C. 20590.
Abstract:
Toyota Cressidas have had motor driven automatic belts since 1981. Their observed use rates have been consistently close to 100%. This paper compares fatality rates in Toyota Cressidas with those in the similar Nissan Maximas (which are equipped with three-point manual belts) using the latest data from the Fatal Accident Reporting System. After making adjustments for differences in the average ages of front seat occupants of the two fleets, the Toyotas have a fatality rate that is about three-quarters that of the Nissans. From this, the fatality-reducing effectiveness for the Toyota automatic belts is estimated to be 40% with an uncertainty of +/- 8%. This effectiveness estimate is consistent with earlier estimates of automatic belt effectiveness.
