Databases are maintained for the claims made under the Compulsory Third Party (CTP) insurance schemes for injuries received in motor vehicle crashes. The statistics that can be presented from the databases show some similarities to and some differences from those presented from the traditional crash databases maintained by Transport Authorities.
This paper presents statistics on CTP claims (and crashes that generated these claims) as maintained by the Motor Accident Commission in South Australia, and compares these with casualty crash statistics from the Crash Register maintained by Transport SA. Comment is made on the differences, and an attempt made to explain these differences. The paper also makes comment on why it is important to produce CTP statistics and why they may generate different concerns and promote different road safety interventions than those identified by the traditional databases.
