Is it permissible to use a handheld phone while driving a commercial vehicle?

The correct choice indicates that using a handheld phone while driving a commercial vehicle is prohibited except in emergency situations. This aligns with federal regulations and safety guidelines designed to minimize distractions for commercial drivers, who operate larger and potentially more dangerous vehicles compared to regular cars.

Under these regulations, using a handheld phone can significantly divert a driver’s attention away from the road, increasing the risk of accidents. However, in true emergencies, it is still acknowledged that a driver may need to use their phone to seek help or communicate urgent information, which is why this exception exists.

Other options imply scenarios that would either allow the use of handheld devices at inappropriate times or dismiss the notion of emergency entirely, which does not reflect the safety standards and legal requirements in place for commercial driving.
