Third DWI Lawyer In Conroe, TX
A third DWI in Texas is a felony with a range of two to ten years in prison, and the two earlier convictions behind it are part of what the state must prove. This page covers the elements, the penalties, how the priors are tested and how a felony DWI moves through Montgomery County.
What Is A Third DWI In Texas?
A third DWI is a DWI arrest of a person with two earlier convictions for intoxicated operating offenses. Under Penal Code § 49.09(b) it is a third degree felony with two to ten years in prison and a fine up to $10,000. The two priors are elements the state must prove, and no time limit applies to them.

Understanding Texas Law
How Does Texas Law Define A Third DWI?
A third DWI is the one felony in the DWI chapter that depends entirely on the driver's history. Nothing about the new night has to be worse than a first offense. Two earlier convictions for intoxicated operation of a vehicle, boat, aircraft or amusement ride are what raise it to a third degree felony under Penal Code § 49.09(b)(2).
On a second DWI, the prior only changes the range. On a third, the two priors become part of the offense. They are what puts the case in a district court instead of a misdemeanor court.
The felony level also brings felony procedure: a grand jury, a district court and, on conviction, a prison range. The felony DWI page explains the other ways a DWI becomes a felony.
Four things must be found beyond a reasonable doubt:
- The driver operated a motor vehicle in a public place
- The driver was intoxicated at the time
- A first qualifying conviction exists and belongs to this driver
- A second qualifying conviction exists and belongs to this driver
Each prior has its own proof problems. It must be final, it must qualify under the statute, and it must be tied to the defendant by more than a matching name. A prior from another state or another decade can raise all three questions at once.
If either prior fails, the felony fails with it.

Penalties And Consequences
What Are The Penalties For A Third DWI In Texas?
The felony range is set by statute. Bond conditions, any earlier felony record and a possible deadly weapon finding change how heavy the case is in practice. These are limits, not predictions.
Texas Department of Criminal Justice.
A condition of community supervision under art. 42A.401.
- Classification
- Third degree felony under Penal Code § 49.09(b)(2).

- Deadly weapon finding
- Can be sought where the vehicle was used in a way capable of causing death or serious bodily injury. It limits probation and delays parole.
- Bond

A deadly weapon finding brings a DWI under the same parole and probation rules as the offenses on the 3G offenses page. Whether the state seeks one shows up in the indictment.
Real Questions

Possible Defenses
How Can A Third DWI Be Defended?
A third DWI is two old cases plus one new one. An attorney reviews each prior for finality, identity and validity, then tests the new arrest like any other DWI. The state carries the burden throughout. No result can be promised.
Old judgments come from other courts, other counties and sometimes other states. They can be incomplete, carry the wrong identifiers or describe an offense that does not match the Texas statute.
A felony built on blood still needs a valid warrant.
Section 724.012(b) of the Transportation Code tells an officer to take a specimen from a driver with two prior DWI convictions. It does not remove the Fourth Amendment. A blood draw still needs a warrant, consent or a recognized exception.
In Montgomery County the No Refusal program puts a prosecutor and an on-call judge behind many warrants, which makes the affidavit a central document in a third DWI file.
Finality Of Each Prior
Is each prior a final conviction, and not a case still pending or on appeal?
Identity
Do fingerprints or photographs identify the defendant, or only a person with the same name?
Out Of State Law
Does the out-of-state prior come from a law that prohibits operating a vehicle while intoxicated?
Counsel On The Old Case
Was the old judgment entered with a lawyer or a valid waiver of counsel?
The Warrant Affidavit
Does it show probable cause within its own four corners, and does the video match it?
The Lab Work
Was the blood drawn, sealed and stored under protocol, and do the lab records support the result?
Local Process
What Happens After A Third DWI Arrest In Montgomery County?
A felony follows a different path from a misdemeanor, and in Montgomery County it leaves the misdemeanor courts entirely. Where it is heard and who prosecutes it are local facts.
Magistrate And Bond
The person is brought before a magistrate, who sets bond. A felony DWI bond can carry an interlock, travel limits and reporting.
The 15 Day ALR Window
The driver asks for an ALR hearing within 15 days after receiving the notice of suspension. The State Office of Administrative Hearings holds it by telephone or videoconference.
Gathering The Prior Records
The certified judgments behind both priors are collected and compared with the statute and the defendant's identity.
Grand Jury
The grand jury can indict on the felony, indict on a lesser offense or return no bill.
District Court
Arraignment, discovery and motions to suppress come first, followed by a plea agreement, dismissal or trial.
- Charging
- Grand jury indictment, presented by the Montgomery County District Attorney's Office.
- Where it is heard
- Heard in the district courts at the Montgomery County Criminal Justice Center on 207 W Phillips St.

Who Handles Your Case
The Texas Lawyer Who Speaks Science
Attorney Brennon Mitchell isn't just a seasoned Conroe trial lawyer. He's one of the few in Texas, and the entire country, to earn the prestigious title of an ACS-CHAL Forensic Lawyer-Scientist. That means he's gone beyond the courtroom and into the laboratory, receiving in-depth, hands-on training in forensic chromatography, the same kind of testing used by crime labs to try and convict Texans every day.
What does that mean for you?
It means when the state uses blood alcohol or drug testing to try to prove its case, Mr. Mitchell knows how to challenge it. He's trained to:
- Analyze lab results and spot faulty science
- Cross-examine forensic experts with precision
- Break down complex chemical evidence in plain language for juries
This is not the kind of background you find in most criminal defense attorneys, and it could make the difference between a conviction and a clean slate.

Common Questions
Third DWI Questions People In Conroe Ask
What makes a DWI a third offense felony in Conroe, TX?
Texas Penal Code § 49.09(b)(2) makes a DWI a third degree felony when the driver has two earlier convictions for an intoxicated operating offense. Boating, flying and amusement ride convictions count toward the two, along with DWI, child passenger DWI, intoxication assault and intoxication manslaughter. The priors can be from any year, and from another state if that state's law prohibits operating a motor vehicle while intoxicated.
How much prison time can a third DWI bring in Montgomery County?
A third DWI is punished within the third degree felony range: two to ten years in the Texas Department of Criminal Justice and a fine up to $10,000. A qualifying earlier felony conviction can raise that range under Penal Code § 12.42. Community supervision is a possible sentence, and it comes with at least ten days in county jail as a required condition.
Where is a third DWI heard in Conroe, TX?
The Montgomery County District Attorney's Office presents the case to a grand jury. If the grand jury indicts, the case is heard in the district courts at the Montgomery County Criminal Justice Center, 207 W Phillips St. That is a different building from the Courts at Law, where first and second DWI cases are filed.
What if only one of the priors can be proven in my Conroe, TX case?
The two priors are elements of the felony. If only one qualifying prior is proven, the felony enhancement fails and the offense falls to the Class A range for a second DWI. If neither is proven, the range is that of a first offense. The new arrest must still be proven on its own facts.
Can police take blood without consent after a third DWI arrest in Conroe?
Transportation Code § 724.012(b) directs an officer to take a specimen when there is credible information of two prior DWI convictions. That statute does not replace the constitutional need for a warrant, consent or a recognized exception. In Montgomery County the No Refusal program gives a prosecutor and an on-call judge a way to produce a blood warrant.
Does a third DWI in Conroe, TX always go to a grand jury?
A felony charge needs an indictment unless the defendant waives it. A grand jury can indict on the felony, indict on a lesser offense, or decline to indict. The decision rests largely on whether the records for both priors hold together, so those records are worth reviewing before the grand jury meets.
