What action is permissible during the operation of a commercial motor vehicle?

Using hands-free communication is permissible during the operation of a commercial motor vehicle because it allows drivers to maintain communication without taking their hands off the wheel or their focus off the road. Regulations often require that drivers minimize distractions while driving, and hands-free devices enable this by permitting voice commands or using Bluetooth technology. This approach enhances safety by reducing the potential for accidents caused by manual distractions.

In contrast, actions such as texting while driving, refueling while on the move, or racing another vehicle are all explicitly unsafe and generally prohibited. Texting diverts attention from the road significantly, refueling could lead to hazardous situations, and racing would not only endanger the driver but also others on the road, violating traffic regulations. Thus, the option of using hands-free communication stands out as a legal and safe practice for commercial vehicle operators.
