Experience Rating Schemes for Fleets of Vehicles

This paper proposes bonus-malus systems for fleets of vehicles, by using the individual characteristics of both the vehicles and the carriers. Bonus-malus coefficients are computed from the history of claims or from the history of safety offences of the carriers and the drivers. The empirical results are derived from a data set obtained from the Société de l’Assurance Automobile du Québec, the public insurer for bodily injuries arid the regulator of road safety.
