This research attempts to evaluate emission measurement of on road vehicle. In this regard, the research develops failure probability model of vehicle emission test for passenger car which utilize binomial logit model. The model focuses on failure of CO and HC emission test for gasoline cars category and Opacity emission test for diesel-fuel cars category as dependent variables, while vehicle age, engine size, brand and type of the cars as independent variables. A survey to measure the vehicle emission and other information of the vehicle was done to the two categories of passenger cars on road. The survey was done at two main roads in Makassar City, one of the large cities in Indonesia. According to calculation result, vehicle age became significant variable to determine the failure probability of vehicle emission test of gasoline cars category. However, engine size gave significant contribution for diesel-fuel cars category.
