Can You Refuse a Breathalyzer in Texas? Suspension and Blood Draws

Yes, you can refuse a breathalyzer in Texas, but the refusal carries real costs. Your license is suspended for 180 days on a first refusal and two years if you’ve had an alcohol-related enforcement contact in the past 10 years. The refusal can be introduced as evidence against you if you’re prosecuted for DWI, and in most cases police can get a warrant and draw your blood anyway. Refusing is a legal right, not a get-out-of-DWI card.

What Happens the Moment You Refuse

Once you decline to provide a breath specimen after a lawful DWI arrest, the officer takes your physical license on the spot and hands you a notice of suspension. The Administrative License Revocation (ALR) program handles what comes next, and it runs completely separately from any criminal case. You can beat the DWI in court and still lose your license for the refusal.

The suspension doesn’t start that night. It takes effect on the 40th day after you receive the notice.¹ That gap exists so you have time to request a hearing. If you don’t live in Texas, the department issues an order denying you a Texas license for the same period instead of suspending your out-of-state one.

Before asking for your breath, the officer is required to warn you — both orally and in writing — that refusal brings an automatic suspension of at least 180 days, that it can be used against you in court, that a warrant for your blood may follow, and that you have 15 days to request a hearing.² Keep the paperwork you receive. If the warnings weren’t given correctly, that becomes grounds to challenge the suspension later.

How Long Your License Is Suspended

The suspension length depends entirely on your record:

First refusal with no prior alcohol-related contacts: 180 days.¹
Refusal with any alcohol-related or drug-related enforcement contact in the previous 10 years: two years.¹

Compare that to what happens if you take the test and fail: a BAC of 0.08 or higher produces a suspension of at least 90 days.² For a driver under 21, any detectable alcohol brings at least a 60-day suspension. The administrative penalty for refusing is roughly double the penalty for failing.

People often assume that without a BAC number, prosecutors can’t build a case. That isn’t how Texas DWI prosecutions work. Convictions regularly come from officer testimony about driving behavior, the smell of alcohol, slurred speech, and failed field sobriety tests. A missing test result doesn’t block the case — it just swaps one piece of evidence for another.

Police Can Still Get Your Blood

Refusing a breath test is not the end of chemical testing. Officers can present an affidavit to a judge and get a warrant for a blood draw, and most Texas counties now run electronic warrant systems that make the process fast, sometimes under an hour. Your refusal often buys delay rather than privacy.

In certain situations, Texas law requires officers to take blood even without a warrant. Under Section 724.012, a mandatory draw applies when:

You were in a crash the officer believes was caused by intoxication, and someone has died, will die, or suffered serious bodily injury.³
The crash caused another person to suffer bodily injury and be transported to a hospital.³
You were arrested for DWI with a child passenger in the vehicle.³
The officer has reliable information that you have a prior conviction for intoxication assault, intoxication manslaughter, or two or more prior DWI-type convictions.³

Outside those categories, Section 724.012(e) still allows a required specimen after a warrant or when probable cause supports exigent circumstances.³ Between the mandatory-draw list and the electronic warrant pipeline, refusal rarely keeps the state from getting a sample.

Your Refusal Becomes Evidence

Texas prosecutors are allowed to tell the jury that you refused. The statute itself requires officers to warn you that a refusal “may be admissible in a subsequent prosecution.”² The argument is familiar: you refused because you knew you’d fail.

Juries tend to find the argument persuasive because it tracks with intuition. A sober driver generally has no reason to decline a quick breath test. Defense attorneys push back by pointing to distrust of the equipment, nervousness, or confusion about rights, but the “consciousness of guilt” framing carries weight. If you refuse hoping to starve the prosecution of proof, understand that the refusal itself can be the proof.

You Have 15 Days to Fight the Suspension

From the date you receive the notice, you have 15 days to request an ALR hearing. The request must reach the Texas Department of Public Safety’s Austin headquarters within that window.² Miss the deadline and you’ve waived the right to contest it — the suspension starts on day 40 regardless.

A timely request pauses the suspension until an administrative judge rules. The hearing is a civil proceeding before the State Office of Administrative Hearings, not criminal court, and the issues are narrow: whether the officer had reasonable suspicion for the stop, whether there was probable cause for the arrest, whether you were properly warned under Section 724.015, and whether you actually refused. A defective warning is often the strongest ground for winning. Winning the hearing doesn’t affect your criminal case, and losing doesn’t guarantee a DWI conviction.

Keeping a License to Drive to Work

If the suspension sticks, you may qualify for an occupational license covering essential needs like work, school, and medical appointments. Texas Transportation Code Section 521.242 extends eligibility to people suspended under Chapter 724, the implied consent chapter.⁴ The DPS confirms that ALR-suspended drivers may apply.⁵

Expect restrictions. The occupational license won’t cover commercial vehicles, and the court order usually limits your hours and routes. For a driver facing a 180-day or two-year suspension, it’s often the difference between keeping and losing a job. Start the process early rather than waiting for the regular license to go dark.

Criminal DWI Penalties Still Apply

Refusing doesn’t shield you from prosecution. If observations, dashcam footage, and field sobriety performance give the state enough, you face DWI penalties with or without a chemical test:

First offense: Class B misdemeanor with a 72-hour minimum jail term. An open container pushes the minimum to six days. A BAC of 0.15 or higher elevates it to a Class A misdemeanor.⁶
Second offense: Class A misdemeanor with a 30-day minimum jail term.⁷
Third offense: Third-degree felony, 2 to 10 years in prison.⁷
DWI in a school zone: State jail felony even on a first offense.⁶

These sit on top of the administrative suspension. You can be serving jail time, paying fines, completing alcohol education, performing community service, and sitting on probation while your license is still suspended from the refusal. One system does not cancel the other.

What a Refusal Actually Costs You

Reinstating your license after an ALR suspension carries a $125 fee at DPS.⁸ That’s the easy number. Add attorney fees for both the ALR hearing and the criminal case, bail, alcohol education programs that typically run $25 to $85, and months or years of alternative transportation.

If a DWI conviction follows the refusal, you may also need an ignition interlock device and SR-22 high-risk insurance. The interlock alone usually runs over $100 per month with installation, calibration, and monitoring. Insurance premiums after a DWI-related suspension often double or triple and stay elevated for years. The breath test refusal that felt like the safer choice at the roadside tends to produce the longer, more expensive aftermath.
