This paper presents an application of the ordered probit model to bus accident data to reveal the most significance factors that affect the severity of vehicle damage. Data recorded by The Department of Traffic Training and Research of the General Directorate of Security Affairs of Turkey for the year 2002 was used. The dependent variable was determined as the severity of damage, and was classified according to four levels: "No damage", "Little damage", "Medium damage" and "High damage". In view of the ordinality of the dependent variable, the use of the ordered probit model was preferred.
