The DWI Court Process In Conroe, TX
The criminal side of a Montgomery County DWI moves through a set order of stages under the Texas Code of Criminal Procedure, and the building it sits in depends on whether it was charged as a misdemeanor or a felony. This page explains what each stage is for and which decisions come early.
How Does A DWI Case Move Through A Texas Court?
A Texas DWI case runs through arrest and booking, a magistrate hearing within 48 hours under article 15.17, charging, discovery under article 39.14, pretrial motions, a plea or trial, sentencing and any appeal. The Code of Criminal Procedure sets those stages for every county. The license case runs separately and starts its own clock.

Understanding Texas Law
How Does A DWI Case Move Through A Texas Court?
The criminal side of a DWI decides whether there is a conviction and what the sentence is. The Code of Criminal Procedure sets its rules for every county in the state. What differs from county to county is who handles each stage and where.
In Conroe, misdemeanor and felony cases are heard in different buildings. A first or second DWI is a misdemeanor, filed in one of the Montgomery County Courts at Law and prosecuted by Montgomery County District Attorney's Office. A felony DWI, such as a third offense, a DWI with a child passenger, or an intoxication assault or manslaughter charge, is heard in the district courts at the Montgomery County Criminal Justice Center on 207 W Phillips St, the building that also houses the Montgomery County District Attorney's Office.
The notice names the court, and a person who reports to the wrong building can miss the setting. A misdemeanor goes forward on an information filed by the prosecutor, while a felony needs an indictment from a grand jury.
Two things already in motion before the first setting:
- Bond conditions set at magistration, which apply from release until the case closes
- The license case, with 15 days to request an ALR hearing
For a repeat DWI, or an intoxication assault or manslaughter charge, article 17.441 directs the magistrate to order an ignition interlock as a bond condition unless it would not serve the interest of justice.
A broken bond condition can lead to the bond being revoked and the person returned to custody, which is a problem separate from the charge.
Penalties And Limits
What Penalties And Time Limits Apply In A Texas DWI Case?
Each stage has its own deadline, and the charge sets the range the court can impose. These are the limits the statutes and rules set, not predictions for any one case.
Article 15.17, counted from arrest.
Three years for most felonies.
90 days if a timely motion for new trial was filed.
- First DWI
- Class B misdemeanor. 72 hours to 180 days in jail and a fine of up to $2,000. Class A, up to one year and $4,000, when the result was 0.15 or more.
- Second DWI
- Class A misdemeanor with a 30 day minimum jail term (Penal Code § 49.09(a)).
- Third DWI
- Third degree felony (§ 49.09(b)), heard in a district court after indictment.
- Deferred adjudication
- Available in some DWI cases since September 1, 2019. Not available when the alcohol concentration was 0.15 or more or when the person held a commercial license (art. 42A.102), and it comes with an ignition interlock requirement (art. 42A.408).
- Who sets punishment
- The judge, unless the defendant elects in writing before jury selection to have the jury assess it (art. 37.07).
- Time limit to file charges
- Two years for a misdemeanor and three years for most felonies (CCP ch. 12).
- Appeal deadline
- Notice of appeal within 30 days of sentencing, or 90 days after a timely motion for new trial (Tex. R. App. P. 26.2).
A case can end at any stage with a dismissal or a plea, and the license case keeps its own schedule throughout.

Possible Defenses
How Do Discovery And Pretrial Motions Shape A DWI Defense?
The evidence a jury hears is settled well before trial. Article 39.14, known as the Michael Morton Act, opens the state's file to the defense: the offense report, dash and body camera footage, the booking video, and the breath or blood records.
A No Refusal case adds to that file. The warrant affidavit, the judge's signature, the record of the draw and the lab's chromatograms all arrive through discovery, and each can be tested before trial. An attorney reads it all to see what the state can prove. No result can be promised.
Texas has its own exclusionary rule.
Under article 38.23, evidence obtained in violation of state or federal law, or of either constitution, may not be used against the accused. In a DWI the first question is often whether the officer had reasonable suspicion to make the stop.
Scientific evidence faces a separate test, which asks whether the technique is valid and was applied properly on that occasion. The breath and field sobriety testing page covers what that looks like for each kind of test.
The Stop
Was there reasonable suspicion to make the stop or begin the contact?
The Arrest
Was there probable cause to arrest for DWI at the time it happened?
The Blood Warrant
Does the affidavit show probable cause on its own words, and was the draw done properly?
The Video
Does the video match the officer's report of the driving and the tests?
The Science
Was the testing method valid and correctly applied on that occasion?
The Charging Document
Does the information or indictment state the offense and any enhancement correctly?
Local Process
How A DWI Moves Through Montgomery County
A case follows the sequence below, though it can stop at any point with a dismissal or a plea and so may never reach the later stages.
Arrest
The arrest is made by one of the county's agencies: Conroe Police Department, Montgomery County Sheriff's Office, Texas DPS Highway Patrol, Montgomery County Constables, Precincts 1 through 5, Willis Police Department, Shenandoah Police Department, Oak Ridge North Police Department, Magnolia Police Department, Splendora Police Department, or Roman Forest Police Department.
Booking
The person is booked at the Montgomery County Jail, 1 Criminal Justice Drive, which the Montgomery County Sheriff's Office runs. Roughly 1,100 beds, with a daily population that regularly runs over a thousand. Sheriff's Office headquarters sits at the same address.
Magistrate
Within 48 hours, a magistrate gives the statutory warnings, addresses the right to counsel and sets bail with any conditions (art. 15.17).
Charging
The prosecutor files an information for a misdemeanor, or presents a felony to a grand jury.
Discovery
The state produces reports, video and testing records on request under art. 39.14, and discloses favorable evidence whenever it comes to light.
Pretrial Hearings
Motions to suppress under art. 38.23, and challenges to scientific evidence, including a blood warrant, are heard before trial.
Resolution
Dismissal, a plea agreement, or a trial before the judge or a jury.
Sentencing And Appeal
If there is a conviction, the court sets a sentence within the statutory range, which can include community supervision. An appeal goes to the Ninth Court of Appeals in Beaumont.
- Where it is filed

Next Steps
What Should You Do As Your DWI Case Moves Through Court?
Choices made in the first weeks of a case limit or open the choices available later. These steps are general information, not advice for any one person.
Calendar Every Setting
Write down each court date and bond condition, and treat the bond terms as rules from release until the case ends.
Check The Building
Confirm from the notice whether the setting is in the misdemeanor courts or the felony courts, and arrive early.
Protect The License Window
Count 15 days from the day you received the notice of suspension and ask about an ALR request right away.
Ask For The Evidence
Make sure a discovery request under article 39.14 goes out, covering video, reports and testing records.
Follow The Interlock Terms
If an ignition interlock is a bond condition, install and use it as ordered.
Hold Off On Pleas
Do not agree to a plea before the evidence has been reviewed and the consequences are known.
Early choices cannot always be undone, and a plea has effects outside the courtroom that are covered on the collateral consequences page. The deferred adjudication page explains that outcome in general.

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.
Brennon graduated from Texas A&M University School of Law and practices from offices in Orange and Conroe.

Common Questions
DWI Court Process Questions People In Conroe Ask
What happens after a DWI arrest in Conroe, TX?
The person is booked into the Montgomery County Jail and brought before a magistrate, which Code of Criminal Procedure article 15.17 requires within 48 hours of arrest. The magistrate gives the statutory warnings and sets bail and any bond conditions. After release the case receives a first court setting, and the separate window to request an ALR hearing is already running.
Which court hears a DWI case in Montgomery County?
The level of the charge decides it. A first or second DWI is a misdemeanor, filed in one of the Montgomery County Courts at Law. A felony DWI is heard in the district courts at the Montgomery County Criminal Justice Center on 207 W Phillips St. Misdemeanors and felonies sit in different buildings in Conroe, so the court named on the setting notice matters.
Who prosecutes a felony DWI in Conroe, TX?
The Montgomery County District Attorney's Office prosecutes felony cases, including felony DWI, intoxication assault and intoxication manslaughter. Its offices are in the Criminal Justice Center, the same building as the criminal district courts. A felony has to be presented to a grand jury, and an indictment returned, before the case goes forward in district court.
What evidence does the state have to share in a Montgomery County DWI case?
Code of Criminal Procedure article 39.14 requires the state, on request, to produce offense reports, recorded statements, and documents and recordings material to the case, including dash and body camera video and testing records. In a No Refusal case that includes the warrant paperwork. The state also has a continuing duty to disclose evidence that tends to negate guilt or reduce punishment.
How long does the state have to file a DWI charge in Conroe, TX?
Texas law sets no fixed timeline for resolving a DWI, and the length of a case depends on discovery, pending lab results, pretrial motions and whether it goes to trial. The state does face a filing deadline of two years from the offense for a misdemeanor and three years for most felonies.
Can a DWI conviction from Montgomery County be appealed?
A conviction can be appealed to the state court of appeals that covers Montgomery County. Under Texas Rule of Appellate Procedure 26.2, the notice of appeal is due within 30 days after sentencing, or within 90 days if a timely motion for new trial was filed. The appeal reviews the trial record for legal error rather than retrying the facts.
