Driving While Intoxicated (DWI) offenses in Texas carry serious criminal consequences, including jail time, fines, license suspension, and long-term damage to employment and educational prospects. However, for first-time, non-violent offenders, Harris County offers an alternative route to traditional prosecution through the DWI Pre-Trial Intervention Program (PTIP).
It is a form of pretrial diversion that, if completed successfully, can allow for dismissal of charges and eventual record expunction. If you are facing DWI charges, a Houston DWI lawyer can help you pursue the best possible legal options to defend your freedom.
What Is the DWI Pre-Trial Intervention Program?
The DWI Pretrial Intervention Program is a voluntary, court-supervised diversion program available to eligible first-time DWI offenders in Harris County, Texas. Rather than proceeding with prosecution, qualifying defendants are offered the opportunity to enter into a contractual agreement with the Harris County District Attorney’s Office.
If the defendant complies with all program terms over the specified period (typically 12 months), the DWI charge will be dismissed. Successful completion also allows the defendant to seek expunction, which erases the criminal record associated with the arrest and charge.
Eligibility Criteria
To qualify for the DWI Pre-Trial Intervention Program in Harris County, a defendant must typically meet the following requirements:
First-Time Offender
- The applicant must have no prior criminal record of convictions, including for DWI, drug possession, assault, theft, or other misdemeanors or felonies.
- Juvenile adjudications may also disqualify the applicant, depending on the nature of the offense.
DWI-First (Class B Misdemeanor)
- The charge must be a first offense DWI under Texas Penal Code § 49.04, which means the defendant was operating a motor vehicle in a public place while intoxicated.
- Offenses with aggravating factors, such as BAC ≥ 0.15, accidents involving injuries, or child passengers are ineligible.
Cooperation at Arrest
- The defendant must have cooperated with law enforcement, meaning no resistance, fleeing, or refusal to submit to a breath or blood test.
- Refusal to provide a chemical specimen may disqualify the applicant.
No Prior Pre-Trial Diversion Participation
- Defendants who have previously completed any diversion program even for unrelated charges are generally ineligible.
No Immigration Holds
- Non-citizens subject to immigration detainers or ICE holds may not qualify, as their legal status complicates program monitoring and completion.
Application Process
The application process for the DWI PTIP involves several steps, all of which must be completed early in the criminal proceedings, typically within 60 days of arraignment. Late applications are generally not accepted.
Step 1: File Notice of Intent
Defense counsel must submit a written notice of intent to apply to the assigned prosecutor and court. This includes the defendant’s identifying information and a waiver of speedy trial rights during the application review.
Step 2: Eligibility Screening
The prosecutor reviews the defendant’s criminal history, case details, police reports, and any available bodycam or dashcam footage. If the applicant appears eligible, the case is scheduled for a PTIP interview and orientation.
Step 3: Interview and Assessment
The defendant meets with a representative from CSCD for a full intake assessment, including:
- Background questionnaire
- Substance abuse screening
- Urinalysis (UA) or hair follicle drug test
- Review of any mental health or treatment needs
This step is critical, as results may impact both eligibility and supervision level.
Step 4: Agreement Signing
If accepted, the defendant enters into a formal Pre-Trial Intervention Agreement, which outlines the conditions of participation. The agreement is signed by:
- The defendant
- Defense counsel
- The prosecuting attorney
- The probation officer
Program Requirements
The Harris County DWI PTIP typically lasts 12 months and involves a combination of monitoring, treatment, and abstention-based compliance. Conditions may vary slightly by individual criminal case but generally include:
Abstinence from Alcohol and Drugs
- No alcohol or illegal drug use is permitted.
- Routine and random urine or blood tests are conducted.
- Some defendants may be required to install an Ignition Interlock Device (IID) or SCRAM bracelet.
Education and Counseling
- Completion of a state-approved DWI education class is mandatory.
- Additional alcohol or substance abuse counseling may be required based on assessment results.
Community Supervision
- The defendant must report to a CSCD officer regularly.
- All appointments, court dates, and classes must be attended without fail.
Community Service
- A fixed number of community service hours (usually 16–40) must be completed through approved nonprofits.
No New Arrests or Law Violations
- A single new charge or arrest is grounds for immediate removal from the program.
As part of the intake process for the Harris County DWI Pre-Trial Intervention Program, participants may be evaluated using the Texas Risk Assessment System
Consequences of Non-Compliance
Failure to comply with program requirements may lead to termination from the program, at which point the District Attorney’s Office resumes prosecution of the original DWI charge. Common reasons for termination include:
- Missed supervision appointments
- Positive drug or alcohol tests
- Failure to attend classes or perform community service
- New arrests or criminal charges
Upon termination, the case returns to the criminal docket, and the defendant may face the full penalties of a DWI conviction, including possible jail time and a permanent criminal record.
Successful Completion and Dismissal
Upon successful completion of the PTIP:
- The DWI case is dismissed with prejudice, meaning it cannot be refiled.
- The defendant is eligible to file a petition for expunction under Texas Code of Criminal Procedure Art. 55.01, which permanently removes the record of the arrest and charge.
Expunction can be filed immediately after dismissal in most cases, although specific timelines may apply depending on the dismissal order’s language.
Expunction is a powerful legal remedy that clears a person’s record, aiding in employment, licensing, education, and housing opportunities.
