There are no state laws in Texas that specifically ban texting while driving for truck drivers, or for most other drivers for that matter. Only school bus drivers and drivers under the age of 18 cannot text from behind the wheel.
However, commercial truck drivers in the Dallas area are also included in the truck laws for texting and driving established by the Federal Motor Carrier Safety Administration (FMCSA). These laws prohibit commercial truck drivers from using cell phones or texting devices while they are at the wheel.
