DPS clarifies the laws regarding the use of wireless communication devices for drivers under 18
Houston County Courier -  August 2009

According to information released by the Texas Department of Public Safety, HB 2730 and HB 339, enacted recently by the 81st Texas Legislature, restrict all drivers under the age of 18 from using a wireless communication device while operating a motor vehicle.
This new restriction applies to licenses issued after Sept. 1 to applicants who are under 18.
All drivers under 18 who were issued an original driver license before Sept. 1 are still restricted from using a wireless communication device during the six-month period following the issuance of that original license.
The use of a wireless communication device cannot be used to make a traffic stop.
