In this paper, the partial relationship between automobile age and risk is studied by means of logistic regression as applied to a large insurance policy data set of more than 211,000 records. Annual mileage and car owner's gender, age, and province of residence are controlled for. Contrary to expectations, the analysis reveals a negative relationship between automobile age and risk. Older cars sustain fewer liability damage accidents, and also fewer injury accidents, than do new cars, other factors being equal. It is thought that this is due to risk compensation (offsetting behavior). Findings presented may have important implications for the cost (in)effectiveness of periodic motor vehicle inspection.
