Your Phone Behind The Wheel

Transp. Code 545.4251 — reading, writing or sending, unless stopped

A Texas driver commits an offense by using a portable wireless communication device to read, write or send an electronic message while operating a motor vehicle, unless the vehicle is stopped. An electronic message is data read from or entered into a device to communicate with another person. The conduct has to happen in the presence or view of a peace officer, or be established by other evidence.

Email
  • Using the device with a hands free device.
  • Navigating with GPS or a navigation system.
  • Reporting illegal activity, summoning emergency help, or entering information into a traffic and road conditions app.
  • Reading a message reasonably believed to concern an emergency.
  • Playing music.

A stop for texting does not by itself let the officer take or look through the phone. A peace officer who stops a vehicle for this offense may not take possession of or inspect the driver's device unless the Code of Criminal Procedure, the Penal Code or other law authorizes it. Speeding, phone use and open containers are the three offenses where a written notice to appear is mandatory for a driver who signs a promise to appear.

The listed uses are affirmative defenses, which a driver raises in court. The section preempts local ordinances on messaging while driving.
