Abstract

The CA/VSC Secondary Safety Rating System is a predictive method for estimating a new vehicle’s performance in the mix of accidents it will predictably encounter. It is published via consumer organisations to allow purchasers to take secondary safety into account when making their buying decisions. About 200 models of vehicle have been inspected and assessed using this system over the past 8 years.

The Folksam Car Safety Ratings deduce the relative safety of different models of car retrospectively, using insurance and police accident data. The results are given wide publicity, again with the intention of influencing consumer decisions.

A subset of 22 car models, common to both rating systems, was selected and the correlation between the predicted safety performance and the actual experience in accidents was examined. This correlation is shown to be high.

The various approaches to safety rating used around the world are discussed and reviewed for their strengths and weaknesses.
