Texas Drunk Driving Laws

Getting pulled over after a few drinks — or getting hit by someone who shouldn't have been behind the wheel — can turn your life upside down in a matter of minutes. Texas drunk driving laws are some of the strictest in the country, and the penalties can follow you for years if you don't understand how the system works.

Whether you're trying to make sense of a first-time DWI charge, wondering how Texas DWI penalties escalate with repeat offenses, or you were injured in a crash caused by an intoxicated driver, this guide breaks down everything in straightforward language — no legal jargon, just the facts you actually need.

If you were injured by a drunk driver rather than charged yourself, the process looks different — you may have a personal injury claim in addition to any criminal case against the at-fault driver. You can read more about the types of harm involved in our overview of common drunk driving accident injuries.

What to Do If You're Pulled Over or Arrested for DWI in Texas

What you do in the first few hours after a traffic stop can shape the outcome of your entire case. Here's a step-by-step breakdown of how a typical Texas DWI arrest unfolds and what to expect at each stage.

1. The traffic stop. An officer needs reasonable suspicion to pull you over — a traffic violation, erratic driving, or a report from another driver. Stay calm, keep your hands visible, and provide your license, registration, and insurance.
2. Field sobriety tests. Officers may ask you to perform standardized field sobriety tests (walk-and-turn, one-leg stand, horizontal gaze nystagmus). These are voluntary in Texas, though refusing may still lead to arrest if the officer has other evidence of intoxication.
3. Breath or blood testing. Under Texas's implied consent law, refusing a breath or blood test after arrest triggers an automatic license suspension — separate from any criminal penalty — even if you're never convicted.
4. Arrest and booking. If the officer determines there's probable cause, you'll be arrested, taken to the station, booked, and typically held until you can post bond or are released to a sober party.
5. The 15-day clock starts. You have only 15 days from the date of arrest to request an Administrative License Revocation (ALR) hearing with the Texas Department of Public Safety, or your license will be automatically suspended.
6. Arraignment and case review. You'll be formally charged, and this is the point where having legal representation becomes critical — an attorney can review whether the stop, testing, and arrest were handled lawfully.
7. Plea negotiations or trial. Many DWI cases resolve through plea agreements, but some go to trial, particularly where evidence of intoxication is disputed or the traffic stop itself may have been unlawful.

If your DWI led to a crash, the steps above run alongside the practical steps every accident victim should take. Our guide on what to do after a drunk driving accident walks through documenting the scene, seeking medical care, and preserving evidence.

Key Facts About Texas DWI Laws

BAC Limits in Texas

• 0.08% — standard legal limit for drivers 21 and older
• 0.04% — legal limit for commercial vehicle drivers (CDL holders)
• Zero tolerance — any detectable alcohol is illegal for drivers under 21 (Minor DUI law)

Texas DWI Penalty Structure

Texas penalties scale up quickly based on prior convictions, BAC level, and aggravating circumstances such as a child passenger or a crash involving injury.

Offense	Classification	Jail Time	Maximum Fine	License Suspension
First DWI	Class B Misdemeanor	3–180 days	$2,000	90 days – 1 year
Second DWI	Class A Misdemeanor	30 days – 1 year	$4,000	180 days – 2 years
Third DWI	3rd Degree Felony	2–10 years	$10,000	180 days – 2 years
DWI with Child Passenger	State Jail Felony	Up to 2 years	$10,000	180 days
Intoxication Assault	3rd Degree Felony	2–10 years	$10,000	Up to 1 year
Intoxication Manslaughter	2nd Degree Felony	2–20 years	$10,000	Up to 2 years

These figures reflect base statutory ranges; actual sentencing depends on the facts of the case, prior record, and negotiations. For a deeper breakdown of how these penalties stack, see our dedicated guide to DUI penalties in Texas.

Administrative License Revocation (ALR)

Separate from the criminal case, Texas DPS can suspend your license through the ALR process if you fail or refuse a breath/blood test. This is a civil proceeding, meaning it moves on its own timeline and standard of proof — you can lose your license here even if the criminal charge is later reduced or dismissed.

Ignition Interlock Requirements

Courts frequently require an ignition interlock device (IID) as a condition of bond, probation, or license reinstatement — particularly for repeat offenders or cases involving a BAC of 0.15% or higher. The device requires a breath sample before the vehicle will start.

Open Container Law

Texas prohibits open alcohol containers in the passenger area of a vehicle on a public highway, regardless of whether the driver is impaired. A conviction is a Class C misdemeanor and can complicate a related DWI case.

Texas Drunk Driving Statistics

Impaired driving remains one of the leading causes of traffic fatalities in Texas. Alcohol-related crashes contribute to thousands of serious injuries and deaths across the state each year, and Texas consistently ranks among the states with the highest number of drunk driving fatalities nationwide, according to the National Highway Traffic Safety Administration (NHTSA).

Weekends, holidays, and late-night hours see a disproportionate share of alcohol-related crashes, and repeat offenders are involved in a significant portion of fatal incidents.

The Real Cost of a Texas DWI

A DWI charge is rarely just a fine. When you add up the direct and indirect costs, a single conviction can run into the thousands of dollars.

• Court fines and fees — up to $2,000–$10,000 depending on the offense level
• Texas DPS surcharges — annual fees required to keep your license active for up to three years after conviction
• Ignition interlock installation and monthly fees — typically several hundred dollars over the required period
• Increased auto insurance premiums — often 50–100% higher for several years
• Bail or bond costs after arrest
• Lost wages from court appearances, license suspension, or jail time
• Legal defense costs for an attorney

If you were injured by an intoxicated driver, the financial picture works differently — you may be entitled to compensation covering medical bills, lost income, and pain and suffering. Costs and typical outcomes vary by case; our guide to the average personal injury settlement in Texas and our breakdown of how much a personal injury lawyer costs in Texas can help you understand what to expect financially before you speak with an attorney.

Common Mistakes People Make After a DWI Arrest or Drunk Driving Accident

If You Were Arrested

• Missing the 15-day ALR deadline — this alone can cost you your license regardless of the criminal outcome.
• Talking too much at the scene — anything said to police can be used later; it's better to remain polite but limit statements.
• Assuming a first offense means minimal consequences — even a first DWI is a permanent criminal record in Texas, since the state doesn't allow non-disclosure for most DWI convictions.
• Not requesting the arrest video and breath/blood test records early — this evidence can be central to a defense.

If You Were Injured by a Drunk Driver

• Delaying medical treatment, which can both harm your health and weaken your claim.
• Giving a recorded statement to the at-fault driver's insurer before understanding your rights.
• Missing Texas's filing deadlines. Our guide on how long you have to file an injury claim in Texas explains the statute of limitations that applies to your situation.
• Underestimating how liability is proven. Establishing fault often requires more than a police report — see our explanation of how to prove liability in a Texas car accident case.

General post-crash steps, from documenting the scene to notifying insurers, are covered in our guide on what to do after a car accident in Texas, and related traffic violations are outlined in our articles on Texas traffic ticket penalties and whether texting and driving is illegal in Texas.

Because Texas DWI and drunk driving accident cases involve overlapping criminal and civil processes, working with a Texas drunk driving lawyer early on can help you avoid missed deadlines and protect both your license and any compensation you may be owed.
