Abstract: Driving comfort is important for any class of vehicle drivers. Seating comfort is very important for drivers who are undergoing extended period of driving and its associated side effects include higher risk of back problems, discomfort in neck, shoulder and thighs. A good sitting position and correct posture are important for drivers to reduce various work related injuries. There are several occupational risk factors that may affect the work performance of heavy vehicle drivers that may lead to health issues. One of these issues is the driver’s exposure to Musculoskeletal Disorders (MSD). MSDs are injuries and disorders that affect the human body’s movement or musculoskeletal system. This is due to the fact that heavy vehicle drivers are often exposed to vibration, prolonged sitting and other postural factors. Some are related to the actual driving task, traffic situation, individual variability and cabin layout. The musculoskeletal disorders are mostly associated with work postures and movements, repetitiveness and pace of work, force of movement, vibration, temperature, workplace layout and monotonous tasks. And these mentioned risk factors may affect not only the health of the heavy vehicle drivers but may also cause related road accidents. In order to determine the occupational risk factors, a study is required to identify the current condition of heavy vehicle drivers in relation to major risk factors. Furthermore, this study aims to determine the significant factors affecting the occurrence of musculoskeletal disorders using statistical analyses.
