The main responsibility of a commercial driver is to operate their vehicles safely and adhere to all traffic laws. This encompasses a wide range of tasks that ensure not only their own safety but also the safety of other road users. Safe operation means being attentive to the driving environment, following speed limits, obeying traffic signals, and monitoring for hazards. Compliance with traffic laws is essential to maintain safety standards and avoid accidents, which can lead to serious consequences for the driver, passengers, and others on the road.

While meeting delivery deadlines is important in the transportation industry, it must be done within the framework of safety. Neglecting safe driving practices in favor of speed undermines the fundamental role of a commercial driver. Maintaining the vehicle's appearance and training new drivers are additional aspects that may be part of a driver's duties, but they do not represent the primary responsibility. Safety and adherence to laws take precedence over all other tasks in the role of a commercial driver.
