This paper compares highway crashes in Québec and Belgium in order to understand their broad geographical distribution. The goal is to prove that highway accidents in both places follow an identical pattern of distribution, the only differentiating factor being the dimension (scale) of the territory in which accidents occur. The study uses models in which three dependent variables are explained by four independent ones, in 52 districts of Belgium and 97 regional municipalities of Québec. Results show some similarities in spatial distribution of accident density, accidents rates and mortality rates and some differences in spatial distribution of motor vehicle ownership. In both cases, highway accidents density and mortality rates are related to the density of population.
