When is it legal to use a mobile phone while driving a commercial vehicle?

Using a mobile phone while driving a commercial vehicle is permitted when utilizing a hands-free device. This allows for communication while keeping both hands on the wheel and the driver's focus on the road, which is critical for maintaining safety. The laws around mobile phone use in vehicles, especially commercial ones, emphasize the need for minimizing distractions.

While hands-free devices are seen as a way to enhance convenience without compromising safety, all drivers must remain vigilant and attentive to their surroundings, regardless of the technology used. In commercial driving contexts, where heavy or large vehicles are involved, the importance of full attention to driving tasks increases.

The other scenarios presented, such as driving with light traffic, pulling over safely, or driving at low speeds, do not provide legal grounds to use a mobile phone for non-hands-free communication. Each of these options fails to uphold the primary goal of ensuring driver focus and public safety while operating commercial vehicles.
