This study investigates the heterogeneity of factor effects on commercial driver stress and burnout using quantile regression. A total of 1,064 questionnaires were collected in Taiwan. The results show that body mass index (BMI), health problems, and perceived safety culture significantly affect the stress level of commercial drivers. The effects produced by these factors vary over the whole distribution and are particularly evident in the upper quantiles. Commercial drivers who have suffered a high level of stress are especially fragile; any increase in BMI or health problems or decrease in perceived safety culture substantially raises their stress level. Meanwhile, stress is the most significant factor affecting work-related burnout. The effect created by stress on burnout level in the upper quantile is almost double the magnitude compared with the lower quantile. The results emphasize the need to take care of commercial drivers experiencing high stress and burnout.
