What is the primary guideline for mobile phone usage while driving in Texas?

In Texas, the primary guideline regarding mobile phone usage while driving is that texting while driving is prohibited, but using hands-free devices is permissible. This rule is established to enhance road safety by minimizing distractions that can lead to accidents. Texting requires the driver's full attention for reading and typing, significantly increasing the risk of a crash. Thus, the law aims to reduce such dangerous behavior by making it illegal.

Hands-free devices, on the other hand, are allowed as they enable drivers to engage in phone calls while keeping both hands on the wheel and their focus on the road. This approach helps maintain a level of communication without compromising driving safety. Other options either misrepresent the restrictions or do not address the critical safety concerns related to mobile phone usage while driving.
