According to the Distracted Driving Law, what can commercial drivers not do while driving?

The correct answer is that commercial drivers cannot hold and enter information into a GPS unit while driving. This is in line with the distracted driving laws, which aim to minimize activities that can divert a driver's attention away from the road. Manipulating a GPS device requires visual, manual, and cognitive attention, making it a significant distraction.

While commercial drivers may be allowed to eat and drink, use a mobile phone with hands-free technology, and listen to the radio, these activities are generally considered less distracting when carried out safely and responsibly. However, actively entering information into a GPS unit is considered an unsafe distraction that can lead to a greater risk of accidents, thus falling under the prohibited behaviors outlined in distracted driving regulations. By maintaining focus on the driving task and avoiding interactions with devices, commercial drivers can help ensure their safety and that of other road users.
