Of the several road crash and injury data sources available for research and for developing policy, the most commonly used source is the police crash report. The aim of this paper is to examine and then compare police and hospital road crash and injury data. The different types of information available from each source will be discussed, as well as their advantages and disadvantages. Misclassification and under-reporting of crashes is examined.
