Texas Hands-Free Cell Phone Law: Rules, Penalties, and Liability

The Texas hands-free cell phone law is not actually a statewide hands-free law. Texas bans texting behind the wheel under Transportation Code Section 545.4251, but it still lets most drivers hold a phone to make a voice call. True hands-free rules kick in only in school zones, for drivers under 18, for commercial drivers, and inside cities that have passed their own stricter ordinances.¹

What the Statewide Texting Ban Prohibits

Section 545.4251, effective September 1, 2017, makes it an offense to use a portable wireless communication device to read, write, or send an electronic message while operating a motor vehicle. The statute defines an electronic message broadly, covering text messages, emails, social media posts, and any data entered into a device to communicate with another person.¹

Manual interaction with your screen for communication is the target. Scrolling a feed, composing an email, or typing into any messaging app all fall inside the ban. Holding your phone to your ear for a call does not, at least under state law.

The statute also contains a stopped-vehicle carveout. You commit an offense only if the vehicle is in motion, so texting at a red light or in a parking lot is not a state offense. That exception disappears inside cities with hands-free ordinances, and it does not exist at all for commercial drivers.

What Is Still Legal Under State Law

The statute lists affirmative defenses. You will not be convicted if your device use falls into one of these categories:¹

Using a GPS or navigation app for directions.
Reporting illegal activity, summoning emergency help, or reading a message you reasonably believed concerned an emergency.
Entering information into a traffic or road-condition app such as Waze.
Activating a function that plays music or audio.
Using the device in a voice-activated or hands-free mode for any purpose.

When Hands-Free Is Actually Required

Separate rules impose true hands-free requirements on specific drivers and locations.

School Crossing Zones

Under Transportation Code Section 545.425, drivers cannot use a handheld wireless communication device in a school crossing zone unless the vehicle is stopped or the driver is using a hands-free device.² This goes further than the texting ban. You cannot hold your phone to your ear to make a call while driving through an active school zone. Signs at the zone boundaries warn drivers of the restriction.

Drivers Under 18

Drivers younger than 18 face a blanket prohibition on handheld device use. They cannot use a wireless device for any purpose while driving, hands-free or otherwise, with a single exception for contacting emergency services.³

Cities With Hands-Free Ordinances

The statewide law sets a floor, not a ceiling. Many Texas cities have adopted hands-free ordinances that prohibit all handheld device use while driving, including voice calls. Austin has been a hands-free city since 2015 and bans using any portable electronic device while operating a vehicle.⁴ San Antonio, El Paso, and other municipalities have similar rules. What is legal on a rural highway can be illegal once you cross a city limit, so if you drive through different Texas cities, the safest approach is to treat the whole state as hands-free and keep your phone mounted or stowed.

Commercial Drivers Follow Federal Rules

If you hold a commercial driver’s license or operate a commercial motor vehicle, federal law adds a separate layer well beyond the Texas texting ban. Under 49 CFR 392.80, commercial drivers cannot text while driving, and the federal definition of driving includes being temporarily stopped in traffic or at a traffic signal. There is no red-light exception.⁵ A companion rule, 49 CFR 392.82, bans reaching for, holding, or dialing a mobile phone to make a voice call in a commercial motor vehicle.

Federal penalties are steep:⁶

Driver fines up to $2,750 per violation.
Employer fines up to $11,000 for allowing or requiring drivers to text or use a handheld phone.
A 60-day CDL disqualification after a second violation within three years.⁷
A 120-day disqualification after a third or subsequent violation within three years.⁷

Motor carriers themselves are prohibited from requiring or allowing drivers to text or use handheld phones, so the obligation runs both ways.

Penalties for a Texting Violation

Fines under the statewide texting ban start modestly and climb with repeat offenses:¹

First offense: a fine between $25 and $99.
Subsequent offenses: a fine between $100 and $200.

The stakes rise sharply when texting causes real harm. If your violation results in serious bodily injury or death, the offense becomes a Class A misdemeanor, punishable by a fine of up to $4,000 and up to one year in county jail.⁸ That is a criminal record, not a traffic ticket.

Where a texting ticket often hurts most is your insurance. Industry data suggests a single texting violation can raise an annual car insurance premium by roughly 9 to 50 percent depending on the insurer and driving history, translating to an extra $150 to $900 per year on a typical policy. Because the surcharge often lasts three years or longer, even a $25 fine can end up costing well over $1,000.

Civil Liability If Texting Causes a Crash

Beyond fines and criminal charges, texting behind the wheel creates serious exposure in a civil lawsuit. If you cause an accident while violating the texting ban, an injured person can invoke negligence per se. Under that doctrine, breaking a safety statute designed to protect others is treated as automatic proof that you breached your duty of care, leaving the injured party to prove only that your texting caused their harm.⁹ That shortcut significantly strengthens a plaintiff’s claim for medical bills, lost income, and other damages.
