Should I Refuse the Breath or Blood Test in Texas?
“Should I refuse the breath test? What about blood?”
If you’re searching that question after you’ve already been arrested, you’re late, but you still need to understand what actually happens in Texas when you say yes or no.
There is a lot of advice online about refusing a breath or blood test after a DWI arrest. Some people say you should always refuse. Others say you should always take the test.
The truth is that it is not that simple.
I’m Steve Sears, a criminal defense attorney and former prosecutor in Frisco, Texas. At The Sears Law Firm, a large part of my practice is focused on DWI defense in Collin County and the DFW area.
I’ve seen thousands of breath and blood cases from both sides. I’m not going to give you some one-size-fits-all slogan like “always refuse” or “always blow.” That kind of advice is lazy and wrong.
Instead, I’m going to explain what you are actually trading either way.
Again, this is general information and not legal advice for your specific situation. If you are facing a DWI charge, you should speak directly with a lawyer about your case.
What Happens If You Agree to a Breath or Blood Test?
First, let’s talk about what happens if you say yes to a test.
Breath Test
If you agree to a breath test, you blow into the machine. If the machine reports that you are over the legal limit, the State now has a number they can use against you in court.
That does not automatically mean your case is over, but you have given them a piece of scientific-looking evidence that they will use to support their argument.
Blood Test
If you consent to a blood test, your blood will be drawn and sent for testing.
Months later, the results come back from the lab. That number can become a major piece of the State’s case.
If you consent to a test and your result is under 0.08, that may help your defense.
If your result is high, it can hurt.
Either way, from a defense standpoint, we are now looking at the traffic stop, the investigation, and the accuracy of the test itself.
At my firm, when there is a breath or blood test involved, we go through the paperwork, maintenance records, and potential lab issues.
These tests are not magic. They involve machines and people, and both can make mistakes.
However, a clean test result is easier for the State to present to a jury than simply saying, “We think he looked drunk.”
What Happens If You Refuse a Breath or Blood Test?
Now let’s talk about what happens if you refuse.
Many people believe refusing a test means the State cannot use evidence against them. That is not how it works in Texas.
Your License Is at Risk
In Texas, refusing a breath or blood test can trigger an attempt to suspend your driver’s license.
You will have an opportunity for a hearing, but the general rule is that a refusal can lead to a longer potential suspension.
Your driver’s license situation is separate from your criminal DWI case, and it needs to be handled quickly.
The Officer May Still Get a Warrant
Refusing a test does not mean the State cannot get your blood.
If an officer obtains a warrant signed by a judge, they may still be able to take a blood sample.
At that point, the State may have both the blood test results and the refusal itself as part of the case.
The State Can Use Your Refusal Against You
A prosecutor may argue at trial:
“He refused because he knew he was drunk.”
We push back against that argument, but you need to understand that this is how the State may try to frame your decision.
Refusing is not a magic shield.
Sometimes it keeps a number out of the case. Sometimes it creates additional issues.
Why There Is No One-Size-Fits-All Answer
Here is the honest truth:
The “right” choice in the moment depends on many factors, including:
- Your driving behavior
- Your performance during the investigation
- Your history
- The officer involved
- The county where the case is happening
- The risks you are willing to accept
Any lawyer who gives you a blanket rule for every situation is selling you a slogan, not serious advice.
What matters now, especially if you have already been arrested, is dealing with the situation you are actually facing.
Whether you blew, gave blood, or refused, the next step is understanding the evidence and building a strategy around the facts.
When clients come to me, I do not waste time judging what happened at 2 a.m. on the side of the road.
We look at the reports, the video, the test or lack of test, the warrant if there was one, and we build a defense based on the evidence that actually exists.
Should You Refuse a Breath or Blood Test in Texas?
There is no universal answer.
If you agree to a test, you give the State a number. That number may help or hurt your case, but it becomes strong evidence they can use.
If you refuse, your license is at risk, the State may still obtain your blood through a warrant, and they may use the refusal against you.
The smartest move after a DWI arrest is not relying on internet advice. It is working with a lawyer who understands DWI law and the local courts who can analyze what actually happened in your case.
