House Bill 243 would ban texting, e-mailing or writing anything on a cell phone while driving.
Talking on a phone -- even without a hands-free device -- would still be permissible. The measure is being debated in legislative committees.
Collin County Sheriff Terry Box has had a similar policy in place for deputies for nearly a year. Patrols aren't even able to access their computer monitors unless they're at a complete stop.
Deputies can only use cell phones with a hands-free device or if an emergency 911 call is being routed to an officer en route to a call.
"I think it's become just as much prevalent as DWI driving, and, yes, it should be regulated," Box said.
