The problem of deaths and injury as a result of road accidents is now acknowledged to be a global phenomenon. As a result authorities in virtually all countries of the world are now concerned about the growth in the number of people killed and seriously injured on their roads including Ghana. The study objective was to identify the variables that mainly contribute to accident severity in the Northern Region and to describe the impact of these variables. This study applied logistic regression to accident-related data collected from MTTU Northern Region traffic-police records in order to examine the contributing factors to accident severity. A total of 398 accident data from 2007-2009 was used. The accident severity (dependent variable) in this study is a dichotomous variable with two categories, Fatal or Non-fatal. Among the variables obtained from police-accident reports, two independent variables were found most significantly associated with accident severity; namely, Over loading and Obstruction.
