The Harris County DWI Pre-Trial Intervention Program (PTI) offers first-time DWI offenders an opportunity to avoid a criminal conviction by completing a structured, rehabilitation-focused program. Participants who meet the requirements can have their case dismissed and their arrest record expunged, helping them move forward without lasting legal consequences.
Key Points:
- Eligibility: First-time offenders with a BAC of up to 0.15 and no serious accidents or significant criminal history.
- Requirements: Includes monthly probation check-ins, 16 hours of community service, a 9-hour alcohol education course, and installation of an alcohol monitoring device.
- Program Duration: Typically lasts 1–2 years.
- Benefits: Successful completion leads to case dismissal and eligibility for record expungement.
The program emphasizes accountability and rehabilitation over punishment, but strict compliance is essential to avoid removal and reinstatement of original charges. Legal representation is recommended to navigate the application process and meet all obligations.
Eligibility Requirements and Application Process
Who Qualifies for the Program
The Harris County DWI Pre-Trial Intervention Program primarily targets first-time DWI offenders, but eligibility is assessed on a case-by-case basis.
To qualify, applicants should generally have no criminal history beyond minor traffic violations. However, the District Attorney’s office may review certain prior arrests or convictions individually. Typically, the program accepts applicants with a BAC of up to 0.15, though borderline cases may also be considered.
Involvement in serious accidents, especially those causing injuries or fatalities, usually results in disqualification. That said, minor incidents might not automatically exclude you from consideration.
It’s important to note that being eligible doesn’t guarantee acceptance. Both the District Attorney’s office and judges have the discretion to approve or deny applications, making the process highly individualized.
How to Apply
The application process begins with a preliminary review by the District Attorney’s office and requires subsequent approval from a judge.
Applicants must submit a written application that includes their personal details, a detailed account of the arrest, and proof of auto insurance. Accuracy and honesty are essential, as this information will be scrutinized throughout the process. Once both the DA and judge approve the application, a TRAS evaluation is conducted. This evaluation assesses the risk of re-offending and identifies any specific program requirements, such as substance abuse treatment. An evaluation fee, subject to change, is also part of this step.
Having legal representation can significantly improve your chances, as an attorney ensures your application is complete and presents your case effectively. Starting early is key – it not only shows responsibility but also provides sufficient time to gather necessary documentation and navigate the evaluations. Since program rules may change, staying updated through legal counsel is highly recommended.

Program Requirements and Participant Duties
Standard Requirements
Participants accepted into the program must meet specific obligations to successfully complete it. These requirements form the foundation of the intervention process and apply to most individuals.
A key component of the program is community service, requiring participants to complete a set number of volunteer hours. This not only reinforces accountability but also serves as a way for participants to give back to the community.
Another requirement is attending DWI-related educational classes. These sessions focus on the serious risks and consequences of impaired driving, aiming to instill a deeper understanding of the impact of such offenses.
Participants are also required to install and maintain an ignition interlock device in their vehicles. This device prevents the car from starting if it detects alcohol on the driver’s breath, creating safety for both the participant and the public.
Regular check-ins with a probation officer are mandatory. These meetings provide ongoing supervision, address concerns, and offer support throughout the program.
To ensure compliance, participants undergo random drug and alcohol testing, including unscheduled breath tests. This helps enforce sobriety and keeps participants aligned with the program’s goals.
Participants must also avoid committing any crimes during the program period, with the exception of minor traffic violations. Criminal activity can lead to immediate removal from the program.
In March 2024, data from the Harris County District Attorney’s Office revealed a 15% increase in program failures due to participants testing positive for alcohol. This prompted stricter monitoring and counseling requirements for new enrollees.
While these are the standard obligations, additional measures may be required based on individual circumstances.
Individual Requirements
Beyond the standard requirements, some participants face additional conditions tailored to their specific situations. The Harris County program emphasizes a personalized approach, recognizing that each case is unique.
The Texas Risk Assessment System (TRAS) evaluation plays a critical role in determining these individualized conditions. This comprehensive assessment evaluates a participant’s risks and needs, guiding decisions about specific program requirements. For instance, the results may indicate whether alcohol or drug treatment is necessary.
In cases where substance abuse is a concern, participants may be required to undergo outpatient or inpatient counseling. This addresses underlying issues that may have contributed to the offense and helps reduce the likelihood of repeat incidents.
Supervision conditions can also vary significantly. Depending on the case, participants might face restrictions on travel, employment requirements, or enhanced monitoring measures.
Failing to meet any program requirement leads to serious consequences. Participants who fall short of their obligations are removed from the program and must face the original DWI penalties.
Additionally, any information provided during the application process can be used against them if they fail to complete the program.
To avoid these outcomes, participants should avoid heavy drug use, excessive drinking, breaking the law, or driving without a valid license.
Meeting all program requirements is crucial for avoiding the full penalties of a DWI conviction.
Program Benefits and Expungement Options
Case Dismissal and Record Expungement
Completing the Harris County DWI Pre-Trial Intervention Program comes with notable perks. Chief among them is the dismissal of your case, which opens the door to expunging your arrest record.
Expungement is a powerful legal tool—it completely erases your arrest record from both the police department and the Texas Department of Public Safety. This is different from an order of non-disclosure, which only seals the records but doesn’t entirely remove them. It’s worth noting that in Texas, the terms “expungement” and “expunction” mean the same thing.
Once you’ve successfully completed the program, the next step is filing a petition for expunction in the county where you were charged. This petition must include supporting evidence. Typically, a hearing is scheduled about 30 days after filing, and the expungement process is usually completed within 4–6 weeks. However, the final destruction of records may take as long as six months. This relatively quick process underscores the program’s aim to provide swift legal resolution.
The cost of pursuing expungement can reach up to $5,000. This includes a base filing fee of roughly $227. It’s also important to know that committing any non-minor offense within two years could void your eligibility for expungement. These expungement options highlight the program’s focus on rehabilitation and second chances.
Expunction is only available if the charge is dismissed without a conviction or deferred adjudication.

Tips for Program Success
Staying Organized and Taking Action
Navigating the Harris County DWI Pre-Trial Intervention Program requires careful attention to rules and deadlines. Participants must juggle several responsibilities, including counseling sessions, community service, drug testing, and regular meetings with probation officers. Missing any of these obligations can lead to removal from the program and the reinstatement of your original charges.
To stay on track, consider using a calendar or planner to keep all your appointments, deadlines, and requirements in one place. Setting reminders can ensure nothing slips through the cracks. Maintaining a written record of your commitments can also help you stay organized and compliant.
The program often requires participants to either hold stable employment or be enrolled as full-time students. If you encounter any challenges that might affect your ability to meet these requirements, it’s crucial to inform your probation officer as soon as possible. Open communication can help prevent minor issues from becoming major setbacks.
Since the program is overseen by the Harris County District Attorney’s Office and can last up to two years, having a support system can make a big difference. Lean on family, friends, or support groups to help you stay motivated and accountable. Additionally, seeking expert legal advice can further strengthen your ability to successfully complete the program.
Using Legal Support
An experienced attorney can be an invaluable resource, offering insight into the program’s requirements and helping you avoid common mistakes. They can clarify your obligations and work with you to create a solid plan for compliance.

A Second Chance with Conditions

Eligibility depends on factors like BAC, criminal history, and accident involvement.
