Which action is illegal while driving a commercial vehicle?

Texting or using a handheld device while driving a commercial vehicle is illegal due to the significant distraction it poses to the driver. This law is put in place to enhance safety not just for the driver but for all road users. Distractions from mobile devices can lead to severe accidents as they take the driver's attention away from the road. The Federal Motor Carrier Safety Administration (FMCSA) has regulations specifically prohibiting commercial drivers from texting while operating a vehicle, making it clear that this behavior compromises safety.

In contrast, using hands-free devices is generally allowed as it keeps the driver’s hands on the wheel and eyes on the road, minimizing distraction. Listening to the radio or adjusting GPS navigation is typically permissible, as long as it is done in a way that does not divert the driver’s focus from safe driving practices.
