How far back can Texas use a prior DWI conviction?

Texas generally does not use a simple 5-year or 10-year lookback rule for felony DWI enhancement. Older qualifying intoxication-related convictions may still be alleged, although the State must prove that the convictions legally qualify and belong to the defendant.

Will I go to prison for a felony DWI in Houston?

While it is a possibility, not every felony DWI case results in prison. Some cases may be resolved through probation, treatment-focused conditions, reduced charges, or negotiated outcomes. Others may require trial. However, cases involving serious bodily injury, death, multiple prior DWIs, or alleged bond violations are often treated more aggressively.

Can a felony DWI be reduced to a misdemeanor?

It depends on the facts, the evidence, the person's criminal history, and the prosecutor's position. Some felony DWI cases may be dismissed, reduced, or resolved through a negotiated outcome. But there is no automatic reduction simply because the person has strong personal circumstances or needs to keep a job.

Is a high BAC a felony DWI in Texas?

No. While a BAC result of 0.15 or higher at the time of analysis can raise a qualifying DWI from a Class B misdemeanor to a Class A misdemeanor, that result alone does not make the offense a felony.

Can you get probation for a felony DWI in Houston?

Community supervision may be legally available in some felony DWI cases, but not to every defendant. Eligibility depends on the exact charge, prior record, any deadly-weapon or other findings, and whether supervision is sought from a judge or jury. Even when community supervision is granted, Texas law may require confinement, ignition interlock, treatment, testing, and other strict conditions.

Can felony DWI probation include jail time?

Yes. A person placed on community supervision for a felony repeat DWI under Texas Penal Code § 49.09(b) generally must serve at least 10 days in county jail as a condition of supervision. Different confinement requirements may apply to intoxication assault, intoxication manslaughter, or other felony intoxication offenses.

Where are felony DWI cases heard in Houston?

Felony DWI cases arising in Houston are generally handled in Harris County district courts. The specific court assignment, docket, and schedule depend on the case, the charging process, and the Harris County criminal court system.

Houston Felony DWI Defense Lawyer

A felony DWI-related case in Houston may involve qualifying prior intoxication convictions, a passenger younger than 15, DWI in an active school crossing zone, serious bodily injury, or death. Depending on the allegation and any applicable enhancement, the offense may be a state jail felony, third-degree felony, second-degree felony, or, in some cases, first-degree felony.

In Houston, felony DWI cases are extremely serious because they can lead to license consequences, strict bond conditions, state jail or prison time, and a felony record. It is a criminal charge that can affect your driver's license, freedom, job, family, housing, immigration status, professional license, and future background checks.

The first step is identifying why the case was filed as a felony. The defense must then examine whether the State can prove intoxication, the felony allegation, and that police followed the law during the stop, arrest, and testing.

What Is DWI in Texas?

DWI under Texas Penal Code § 49.04 is generally defined as operating a motor vehicle in a public place while intoxicated.

Note that intoxication in a DWI case does not always depend on alcohol. Over-the-counter medicine, prescription medication, illegal drugs, or a combination of substances can also be involved.

Texas Penal Code § 49.01 defines "intoxicated" as either having:

A blood alcohol concentration, or BAC, of 0.08 or more; or
Lost the normal use of their mental or physical abilities because of alcohol, drugs, medication, a controlled substance, or another substance.

So apart from the breath and blood test results, the State may use other types of evidence in a DWI case. That includes officer observations, statements, driving behavior, field sobriety tests, videos, and witness testimony.

What Felony DWI and Intoxication Charges Can Be Filed in Houston?

A DWI does not become a felony simply because someone was arrested, had a high BAC result, or was involved in an accident. The State must have a legal reason to file or enhance the charge as a felony.

Common felony DWI allegations in Houston include:

DWI with a child passenger: Driving while intoxicated with a passenger younger than 15 is a state jail felony under Texas Penal Code § 49.045.
Third or subsequent DWI: A DWI is generally a third-degree felony if the State proves either two prior qualifying intoxication-related convictions or one prior intoxication manslaughter conviction. Certain substantially similar out-of-state convictions may also qualify.
Intoxication assault: Causing serious bodily injury to another person because of intoxication is generally a third-degree felony under Texas Penal Code § 49.07.
Intoxication manslaughter: Causing another person's death because of intoxication is generally a second-degree felony under Texas Penal Code § 49.08.
DWI in a school crossing zone: For an offense committed on or after September 1, 2025, DWI under § 49.04 is a state jail felony if the person was operating the motor vehicle in a school crossing zone while the reduced speed limit applied.

For intoxication assault and intoxication manslaughter, proof of intoxication alone is not enough. The State must also prove that, by reason of the person's intoxication, the person caused the serious bodily injury or death. Causation may be disputed when other drivers, road conditions, medical complications, or other events contributed to the result.

What Are the Penalties for a Felony DWI in Houston?

The table below shows the possible penalties for a felony DWI in Harris County. But the exact punishment range depends on the exact charge, criminal history, and whether any additional enhancement applies.

Felony Level	Possible Penalties	Common Felony DWI Examples
State jail felony	180 days to 2 years in state jail and a fine up to $10,000	DWI with a child passenger; qualifying school crossing zone DWI
Third-degree felony	2 to 10 years in prison and a fine up to $10,000	Third or subsequent DWI; most intoxication assault cases
Second-degree felony	2 to 20 years in prison and a fine up to $10,000	Most intoxication manslaughter cases

A felony DWI conviction can also lead to consequences outside the sentence itself. These may include probation conditions, alcohol or drug treatment, ignition interlock, license suspension, SR-22 insurance requirements, travel limits, firearm consequences, immigration concerns, and problems with employment or housing.

For licensed professionals, a felony DWI can also create reporting or disciplinary issues. Nurses, teachers, commercial drivers, pilots, real estate professionals, security workers, and people with trade licenses may face consequences beyond the criminal court.

What Happens After a Felony DWI Arrest in Houston?

After a felony DWI arrest in Harris County, the investigation begins immediately. Depending on the circumstances, the Texas Department of Public Safety (DPS), Houston Police Department, Harris County Sheriff's Office, or METRO Police may investigate the case. The evidence may include traffic-stop video, body-camera footage, roadside sobriety tests, breath or blood testing, a blood warrant, crash evidence, medical records, witness statements, and prior conviction records.

Every case is different, but a felony DWI case in Houston often moves through these stages:

Arrest and booking: After arrest, the person may be taken to jail for booking. The case may begin with a complaint, probable cause review, and bond process.
Bond and release conditions: A magistrate or judge may set the bond and release conditions. These may include no alcohol, random testing, an ignition interlock device, GPS monitoring, and travel limits.
Administrative License Revocation (ALR) case: This driver's license case is separate from the criminal case. If you received a DIC-25 notice after a DWI arrest, you generally have 15 days from the date you received notice to request an ALR hearing. Missing the deadline can lead to an automatic license suspension.
Felony filing and district court setting: Prosecutors generally present the charge to a grand jury and seek an indictment before the felony case proceeds to final disposition in district court. Bond proceedings, court settings, evidence preservation, and other legal work may occur before indictment.
Evidence review and motions: During this stage, the defense reviews police reports, body-camera footage, breath or blood test records, laboratory documentation, search warrants, medical records, crash evidence, and prior conviction records when relevant. Attorneys also evaluate whether constitutional violations, forensic issues, or evidentiary weaknesses provide grounds to challenge the prosecution's case.
Negotiation, dismissal, or trial: Some cases are resolved through plea negotiations or dismissed. Whether a charge can be reduced depends on the evidence, the facts, the criminal history, and the prosecutor's position.

Note: If an ALR hearing is not requested before the deadline, the suspension generally begins on the 40th day after the notice was served.

Possible Defenses to a Felony DWI Charge

The defense in a felony DWI case depends on the facts, but common issues may include whether:

Police had a legal reason to stop, detain, or arrest the driver
Field sobriety tests were properly administered and interpreted
A breath or blood test was reliable, timely, and properly handled
A blood warrant, blood draw, or lab procedure can be challenged
The State can prove the driver was intoxicated at the time of driving
The alleged intoxication caused the injury or death
Prior DWI convictions are legally valid for felony enhancement
The State has admissible evidence supporting the child-passenger, school-zone, injury, or death allegation

Why Prior Convictions Matter in a Felony DWI Case

A third or subsequent DWI case usually becomes a felony due to prior convictions. But the old convictions should still be examined carefully.

The State must connect the defendant to the prior convictions. Prosecutors may use certified judgments, fingerprints, court records, and other identification evidence. If the prior case happened outside Texas, prosecutors may also need to show that the out-of-state offense is similar enough to qualify under Texas law.

Possible issues include:

Missing records
Non-final prior cases
Incorrect identity information
Clerical errors in judgments or charging documents
Out-of-state convictions that do not legally match Texas law
Prior cases that are not qualifying intoxication-related offenses
