First DWI Lawyer In Conroe, TX
A first DWI in Texas is a Class B misdemeanor, and in Montgomery County it can rest on a blood sample taken under a warrant after a refused breath test. This page explains what the state must prove, the penalties, how first offense cases are examined, and what to do in the first days.
What Is A First DWI In Texas?
A first DWI under Texas Penal Code § 49.04 means operating a motor vehicle in a public place while intoxicated. Intoxicated means a 0.08 alcohol concentration or more, or not having the normal use of mental or physical faculties. A first offense is a Class B misdemeanor, or a Class A misdemeanor at 0.15 or more. The state must prove each part beyond a reasonable doubt.

Understanding Texas Law
How Does Texas Law Define A First DWI?
A first DWI charge comes from Penal Code § 49.04. The statute does not require a crash, poor driving or a test number. The prosecutor has to prove that the person was operating a motor vehicle in a public place while intoxicated.
Section 49.01 gives "intoxicated" two meanings, and the state can use either one or both.
- An alcohol concentration of 0.08 or more
- Not having the normal use of mental or physical faculties because of alcohol, a drug, a dangerous drug or another substance
The second meaning needs no number. A driver can be charged with a result under 0.08, or with no result at all, if an officer believes alcohol or a drug affected how the person drove, walked or talked.
What the state must prove beyond a reasonable doubt:
- The person operated a motor vehicle
- The vehicle was in a public place in Montgomery County
- The person was intoxicated while doing it
"Public place" reaches well past highways. It covers parking lots, driveways open to customers and any place the public can enter. "Operating" is also broad. Texas courts ask whether the person took action to affect how the vehicle worked, so a car parked with the engine running can become a fact dispute of its own.
Three facts can lift a first arrest above a plain Class B charge: a result of 0.15 or more, an open container, or a passenger younger than 15. The last one is a felony, covered on the child passenger page.

Penalties And Consequences
What Are The Penalties For A First DWI In Texas?
The numbers below are the limits the statute sets. They describe the most a court may order, not what will happen in any one case, and a judge can order community supervision in place of some or all of the jail time.
Six days minimum with an open container.
Up to $4,000 and one year for a Class A.
Separate from the ALR case.
$6,000 at 0.15 or more. Waived on a finding of indigence.
- Classification
- Class B misdemeanor. Class A misdemeanor if the blood or breath result was 0.15 or more.
- Jail
- Class B: 72 hours to 180 days. Class A: up to one year. The minimum is six days when an open container was in the driver's immediate possession.
- Fine
- Class B: up to $2,000. Class A: up to $4,000. Court costs and program fees come on top.
- Community supervision
- A judge can place a person on probation, with conditions the court sets, instead of ordering all of the jail time.
- Administrative suspension
- 90 days after a failed test, 180 days after a refusal, on a first contact. It runs through the ALR process, not the criminal court.
- Suspension on conviction
- 90 days to one year under Transportation Code § 521.344.
- State traffic fine
- $3,000 on a first conviction in 36 months, $4,500 on a second or later, $6,000 at 0.15 or more (Transportation Code § 709.001).
- Record
- A conviction is a permanent public record and cannot be expunged. Texas has no lookback limit, so it can enhance a later DWI at any time.
A second DWI is a Class A misdemeanor with a 30 day minimum, and a third is a felony. That is why the way a first case ends matters well beyond its own sentence.

Possible Defenses
How Can A First DWI Be Defended?
A DWI file is built from separate pieces of evidence, and each piece has its own rules. An attorney reads the whole file to see what the state can prove, where the pieces disagree and whether any step went outside the law. No result can be promised.
The review starts at the beginning, with the reason for the stop, and follows the evidence forward through the roadside tests, the arrest, the specimen and the paperwork the officer wrote.
- The reason for the stop and the length of the detention
- How the roadside tests were explained, given and scored
- Whether the person was actually operating the vehicle
- How the breath or blood evidence was obtained and handled
A number on paper is the end of a process.
Breath results depend on an instrument, an operator and a certification program. Blood results depend on a warrant or consent, a nurse, a sealed tube, a chain of custody and a laboratory run. Each step leaves records, and the records can be requested and compared with the officer's report.
Dash and body camera video often add facts a report leaves out. Attorney Brennon Mitchell holds the ACS-CHAL Forensic Lawyer-Scientist credential, which includes training in the chromatography labs use to measure alcohol and drugs in blood. That helps with reading a lab file. It does not decide how any one case ends.

Was The Stop Lawful?
Did the officer have a recognized reason to stop and detain the driver?
Were The Roadside Tests Fair?
Were the instructions, the surface, the lighting and the scoring consistent with the training manual?
Who Was Operating?
Can the state place this person in control of the vehicle at the right time and place?
Does The Warrant Hold Up?
Does the affidavit, read on its own, show probable cause, and does it match the video?
Was The Sample Handled Correctly?
Do the draw, the storage and the lab data support the reported concentration?
Was The Arrest Lawful?
Did the arrest and the statutory warnings follow constitutional and statutory requirements?
Local Process
What Happens After A First DWI Arrest In Montgomery County?
The steps below follow Texas law across the state. Which court takes the case, who prosecutes it and where a person is held are specific to Montgomery County.
Booking And The Magistrate
After arrest the person is booked and brought before a magistrate, who explains the charge and sets bond. Code of Criminal Procedure article 15.17 sets the timing of that appearance.
The 15 Day ALR Window
A request for an ALR hearing goes to the Texas Department of Public Safety, and a judge from the State Office of Administrative Hearings hears it by telephone or videoconference. The request is due within 15 days after the person receives the notice of suspension.
Charging And Evidence
The case is filed and set for court. The defense can ask for the state's evidence, including video, reports, instrument records and lab files, under article 39.14.
Resolution
After the evidence is reviewed, a first DWI can move toward dismissal, a reduction, a plea, a pretrial program where one exists or a trial. The evidence decides which of those is open.
- Where it is filed
- Filed in one of the Montgomery County Courts at Law, in a different building from the felony courts, and prosecuted by Montgomery County District Attorney's Office.
- Who makes the arrest
- 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.
- Where you are booked
- The Montgomery County Jail at 1 Criminal Justice Drive, run by the Montgomery County Sheriff's Office.
- Blood evidence
- On weekends, holidays and announced enforcement periods, the No Refusal program means a refused breath test can be followed by a warrant for blood.
- If the case is appealed
- Appeals go to the Ninth Court of Appeals in Beaumont.
Next Steps
What Should You Do After A First DWI Arrest?
The first days matter mostly because two deadlines start without any court date. These steps are general information, not advice for any one person.
Find The Notice Date
Look at the notice of suspension and count 15 days from the day you received it.
Ask About An ALR Hearing
Raise the hearing request right away, before the window closes.
Keep Every Paper
Save the notice, the bond papers, any refusal or consent form and every court notice.
Write Down The Night
Record where you were, what you ate and drank and when, and what the officer said.
Stay Quiet Online
Do not post about the arrest, the officer or the case.
Treat The Number As One Fact
A test result is one piece of evidence. It does not settle the case.
Speak with a lawyer before deciding how to answer the charge. Many people plead early, or let the license deadline pass, because they assume nothing can be done, and neither step can be taken back. Mitchell Law Firm offers a confidential conversation about a first DWI charge in Montgomery County, and an early call keeps the most options open.

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
First DWI Questions People In Conroe Ask
What is the jail range for a first DWI in Conroe, TX?
Texas Penal Code § 49.04 makes a first DWI a Class B misdemeanor, with 72 hours to 180 days in county jail and a fine up to $2,000. An open container in the immediate possession of the driver raises the minimum to six days. A result of 0.15 or more makes it a Class A misdemeanor, with up to one year in jail and a fine up to $4,000.
What happens if I refuse a breath test during a Montgomery County No Refusal period?
During an announced No Refusal period, the officer can contact an on-duty prosecutor who drafts a blood search warrant. An on-call judge reviews the sworn affidavit for probable cause, and if the judge signs it, a nurse draws blood. The refusal also carries its own license suspension, and it can be offered as evidence at trial.
Which court hears a first DWI in Montgomery County?
A first DWI is a misdemeanor, so it is filed in one of the Montgomery County Courts at Law, not in a district court. The felony district courts sit in a different building, the Criminal Justice Center on West Phillips Street. The court setting notice names the specific court and its location, so check it before any date.
Can a first DWI in Montgomery County be sealed or expunged?
A DWI conviction cannot be expunged in Texas. A case that ends in dismissal or acquittal can qualify for expunction, and some DWI outcomes can qualify for an order of nondisclosure, which seals the record from most public view. Eligibility depends on how the case ended, the alcohol concentration and the waiting periods in the statute.
How long can my license be suspended after a first DWI arrest in Conroe, TX?
The administrative suspension is 90 days after a failed breath or blood test and 180 days after a refusal, on a first contact. A conviction adds a separate suspension of 90 days to one year under the Transportation Code. A timely ALR request keeps the administrative suspension from starting until the hearing is decided.
Do I need a lawyer for a first DWI in Conroe, TX?
A first DWI brings a permanent record, a jail range, a fine and a license suspension that starts on its own deadline. An attorney can review the stop, the testing and the warrant paperwork, request the state's evidence and protect the 15 day ALR window. Anyone charged can talk through the options with a lawyer before deciding how to proceed.
