Traffic Violations among Truck Drivers Due to Fatigue and Sleepiness

This study aims at capturing prevalence of traffic violations among long-haul truck drivers due to fatigue and sleepiness. The study is based on a roadside survey of 453 long-haul truck drivers, stopping at eateries and rest locations on highways connected to three Indian cities- Mumbai, Indore and Nagpur. The survey questionnaire was categorized into three sections: driver demographics, work-rest schedules and safety critical driver behavior (violations and lapses) in the last five years. A descriptive analysis of the survey results indicated that in the last five years, 36% drivers violated the ‘12-hr rule’ of working duration, 19% were under-educated than mandatory qualifications, and 20% reported frequent incidences of falling asleep while driving. The questions regarding unsafe driving practices like speeding, overtaking were combined to form a single factor ‘violations’ using Principal Component Analysis (PCA). A generalized linear model using negative binomial regression was used to predict the factors related to the prevalence of ‘violations’. According to the model results, young drivers (aged below 25 years), longer working hours, insufficient sleeping hours, driving after mid-night and frequent traffic violations were found to be significant predictors of violations among the long-haul truck drivers. Sleepiness on the wheel, one of the unrecognized factors capable of influencing violations, increased the odds of violations by 1.64 times. An independent sample t-test shows significant differences among violation scores of drivers involved in accidents and other drivers. The study highlights the role of driver fatigue and sleepiness in promoting traffic rule violations among long-haul truck drivers.
