Objectives:
To examine the effectiveness of safety belts.
Methodology:
Accident data fromAlabamawas collected between 1984 and 1987, including information on occupants who were uninjured. The proportion of occupants suffering different severities of injury were calculated and compared.
Key Findings:
-
The effectiveness of seat belts at preventing fatalities in the rear was estimated at 8%, with no confidence intervals provided in the paper.
-
There were very low numbers of restrained passengers who were fatally injured in the rear which were recorded by the police in the time period.
-
The lap belts were estimated to be 57% effective at preventing serious injuries in the rear, with a standard error of 0.74%.
