It can not be denied that along with the increasing number of vehicles on the road, the number of traffic accidents naturally facing increment. This research identifies and analyzes potential errors that Taksi Kosti Solo drivers experienced during driving. In this research, Systematic Human Error Reduction and Prediction Approach (SHERPA) method is used to identify potential errors during driving and analyze the potential errors.
