Which action is mandatory for companies that employ commercial drivers?

Maintaining accurate logs of driver work hours is a mandatory action for companies that employ commercial drivers. This requirement is essential for ensuring compliance with regulations that govern driving hours, rest periods, and overall driver safety. Accurate logging helps prevent driver fatigue, which can lead to accidents and injuries on the road, thus promoting a safer working environment. Furthermore, these logs are often subject to inspection by regulatory authorities to ensure adherence to legal standards, making it crucial for companies to keep precise records.

In contrast, offering regular bonuses, providing training only on weekends, and allowing drivers to manage their own hours are not mandated actions. While bonuses may be a good business practice and training is important, they do not directly address the required regulatory practices that prioritize safety and compliance with work hour restrictions.
