When are you allowed to use your handheld device while driving a CMV?

Using a handheld device while driving a commercial motor vehicle (CMV) is prohibited at all times to ensure the safety of the driver, passengers, and others on the road. This restriction is in place because distractions caused by handheld devices can significantly increase the risk of accidents. Drivers of CMVs are responsible for larger vehicles that require more attention and control, making it even more critical to avoid any distractions while operating the vehicle.

The other scenarios mentioned suggest limited circumstances under which a driver might think it is acceptable to use a handheld device. However, even being stopped at a traffic light does not negate the potential for distraction or the need for full attention on the road. Emergencies require quick thinking and response, and while drivers must address emergencies responsibly, using handheld devices should be minimized in general practice. Dialing with one hand might seem practical, but it still diverts attention from driving, which could lead to dangerous situations. Therefore, the policy is clear: drivers of CMVs must refrain from using handheld devices at all times while driving.
