Two specific sections of the Federal Motor Carrier Safety Regulations (FMCSRs) prohibit CMV drivers from using hand-held phones and texting while driving. The following bullets are derived from FMCSR 392.80, Prohibition against texting, and 392.82, Using a hand-held mobile telephone --
• Don’t text while driving.
• Don’t use your hand-held mobile telephone while driving.
• Driving includes operating a CMV with the motor running while temporarily stationary because of traffic, a traffic control device, or other momentary delays.
• Driving does not include operating a CMV with or without the motor running when the vehicle has been moved to the side of, or off, a highway, and halted in a location where the vehicle can safely remain stationary.
The FMCSRs also ban the use of radar detectors in CMVs and prohibit driving CMVs equipped with a radar detector.
