After a DWI arrest, the criminal charge isn't the only issue you'll face. In Houston, a DWI arrest can also trigger a separate process that could affect your driver's license. You may have to navigate booking and bond, court appearances, evidence review, pretrial motions, negotiations, and potentially a trial.
And that's on top of fears about whether your job is in jeopardy, potential social stigma, increased car insurance costs, fines and fees, and whether you'll have to spend time in jail.
Not knowing what happens next can make those concerns even more stressful. Understanding each step of the Houston DWI process can help you know what to expect and where you may have opportunities to protect your license, record, and future.

Houston DWI Process at a Glance
Resolving a DWI case in Harris County won't necessarily be fast. Our internal case records show it can take six to nine months for a straightforward misdemeanor DWI, while felony cases can linger for two years (or more).
For a DWI conviction under Texas Penal Code § 49.04, the State must prove that you were operating a motor vehicle in a public place while intoxicated. Intoxication is defined under Texas Penal Code § 49.01 as having a blood alcohol concentration (BAC) of 0.08% or higher, or lacking the normal use of mental or physical faculties due to alcohol, drugs, medication, or a combination of substances.
The DWI process in Houston may include the following steps:
- Traffic stop
- Roadside investigation
- Arrest
- Breath/blood testing
- Booking
- Bond
- ALR case
- Criminal case
- First court setting
- Discovery
- Pretrial litigation
- Negotiations
- Trial
Note: The exact sequence can change.
Traffic Stop or Initial Police Contact
In a DWI case that stems from a traffic stop, the officer may report that the driver smelled of alcohol or had slurred speech or glassy eyes. While these are not solid proof of intoxication, prosecutors can use them as evidence.
An officer may also request the driver to do any of the three standardized field sobriety tests (SFSTs):
- Horizontal Gaze Nystagmus (HGN)
- Walk-and-Turn
- One-Leg Stand
Apart from a traffic stop, other situations that may start a DWI investigation include:
- Traffic violations like speeding and unsafe driving
- Driver found asleep in a vehicle
- Car crash
Note: It's not just Houston police officers who can arrest a person for DWI. Harris County Sheriff's deputies, Texas Department of Public Safety (DPS) troopers, constables, and other law enforcement officers can also do so.
Arrest, Chemical Testing, and Booking in Houston
An officer needs probable cause to make a DWI arrest. But it doesn't automatically prove that the person is guilty. At the trial, prosecutors will still have the burden of proving all required elements of DWI.
After an arrest, the officer may proceed to:
- Transport you for booking
- Ask you for a breath or blood sample
Before requesting a breath/blood sample, an officer must give you statutory warnings about the possible consequences if you fail or refuse the test. But even if you refuse testing, the officer can request a search warrant to get a blood sample.
During booking, they will collect your fingerprints, take your photo, and enter your arrest information into the jail system.

Bail and Bond Conditions for a Houston DWI Case
Depending on the facts of the case and the court's decision, you may need to post bail or be approved for a personal recognizance (PR) bond before getting released from a Houston jail.
Personal (PR) bonds are relatively common in Harris County misdemeanor DWI cases, but aren't guaranteed.
The magistrate or judge may also require you to follow bond conditions, such as:
- No alcohol or illegal drug use
- Ignition interlock device (IID)
- Alcohol or drug testing
- SCRAM or other alcohol monitoring requirements
- Reporting to Harris County pretrial services
- Travel restrictions
- No new criminal offense

Administrative License Revocation (ALR) Case
Most people dealing with a DWI case don't realize that sometimes your DWI can involve two cases on separate tracks: A criminal case and an Administrative License Revocation (ALR) case.
If you refuse or fail a breath or blood test, Texas DPS may initiate an ALR case that can revoke or suspend your driver's license. This case is separate from the criminal DWI case.
After receiving a DIC-25 notice, you generally have 15 days to request an ALR hearing to challenge the proposed license suspension. If you miss the deadline, your hearing request will be denied, and the proposed suspension may take effect without a hearing.
The primary purpose of an ALR hearing is to challenge the proposed driver's license suspension. But it can also give an experienced DWI lawyer an early opportunity to question the arresting officer and learn more about the evidence and testimony that could later become important in your criminal case. In Harris County specifically, if a properly subpoenaed officer fails to appear for an ALR hearing without good cause, it can also create an opportunity to save your license.
If your license is ultimately suspended through the ALR process, your lawyer may be able to help you acquire an occupational driver's license (ODL) that allows you to drive on a limited basis to work, school, and certain essential household duties.
Evidence Review, Court Settings, and Motions
Your first court date in Harris County usually won't be a trial. The court may check whether you have a lawyer, review your bond rules, and set future court dates. Your lawyer can also begin reviewing the evidence, and you may have to return to court several times before your DWI case ends or goes to trial.
In Harris County, the County Criminal Courts at Law generally handle misdemeanor DWI cases, while the Criminal District Courts handle felony DWI cases. If your case cannot be resolved before trial, it may eventually be set for a jury or bench trial.
This is where you have to play the waiting game. While the first stages after a DWI arrest can move very quickly, the criminal case itself may take considerably longer. During this period, the defense and prosecution may exchange evidence, discuss legal issues, file motions, evaluate testing records, and consider whether the case can be resolved without trial.
Trial or a Case Resolution
Depending on the evidence and legal issues, your DWI case may be dismissed, reduced, resolved through a plea agreement, placed on community supervision, or tried before a judge or jury.
But if your case goes to trial, the State must prove that you operated a motor vehicle in a public place while intoxicated. Your DWI defense attorney may challenge the evidence, including:
- The reason for the stop
- Police reports
- Witness statements
- Body cam and dash cam videos
- SFST instructions and performance
- Breath/blood test results
