Drivers identified as having either high or low trait stress were interviewed over cellular telephones when experiencing either high or low traffic congestion to assess state driver stress. State stress was greater when experiencing high traffic congestion. In both conditions, time urgency and perceiving driving to be stressful were predictors of state driver stress. Perceived control was a significant negative predictor of state driver stress in high traffic congestion, and it approached significance as a negative predictor of state stress in the low congestion condition. Occupational stress only predicted state driver stress in low traffic. An interaction between trait driver stress and occupational stress approached significance in the low congestion condition. No gender differences in state driver stress were found. (Author/publisher)
