  4. D
    Manually dialing a ten-digit telephone number as long as vehicle speed is below 15 mph

Answer

Using a voice-activated dialing feature or a single button press on a device mounted close to the driver
Federal regulations allow mobile phone use only via compliant hands-free technology, requiring the phone to be mounted within immediate reach so that the driver can initiate or end calls using voice activation or a single button press without removing their safety belt.

Step-by-Step Solution

1
Identify the federal safety standards governing mobile phone use in commercial motor vehicles.
The Federal Motor Carrier Safety Administration (FMCSA) prohibits hand-held mobile phone use and manual dialing while operating a CMV.
Commercial drivers are subject to strict distracted driving regulations to prevent cognitive, manual, and visual inattention.
2
Evaluate the compliant conditions for hands-free mobile device communication.
A driver may only use a hands-free phone if it is mounted close to them and can be operated with one-touch initiation or voice commands without unfastening the seatbelt.
This prevents the driver from taking their eyes off the forward roadway or removing their hands from vehicle controls for extended periods.
