DWI with Enhancements Attorney in Collin County

A Collin County Firm With Over a Decade Fighting Enhanced DWI Charges

A DWI with enhancements in Collin County isn’t a standard DWI case. The moment of arrest starts two clocks running simultaneously: the criminal proceeding and the Administrative License Revocation (ALR) process. Texas law gives you only 15 days from the date of arrest to request an ALR hearing contesting your license suspension. Miss that window and your license is automatically suspended, regardless of how the criminal case resolves. Having a firm based inside Collin County, with relationships established across the local legal system, matters from day one.

We represent clients facing every category of enhanced DWI charge, from high-BAC first offenses to intoxication manslaughter.

How a Standard DWI Becomes an Enhanced Charge in Texas

Under Texas Penal Code § 49.04, a DWI offense occurs when a person operates a motor vehicle in a public place while intoxicated. “Intoxicated” means either lacking the normal use of mental or physical faculties due to alcohol or drugs, or having a blood alcohol concentration (BAC) of 0.08 or more.

A standard first-offense DWI is a Class B misdemeanor. Certain aggravating factors or prior convictions enhance the charge and significantly increase potential penalties. Under § 49.09, Texas applies a lifetime look-back period for prior intoxication-related convictions, meaning a DWI, FWI, or BWI from decades ago can still elevate a new charge today.

The five primary enhancement pathways under Texas Penal Code Chapter 49 are:

• Prior Convictions (§ 49.09): One prior intoxication-related conviction raises a new DWI from a Class B misdemeanor to a Class A misdemeanor or felony, depending on the number of priors. Because the look-back period is lifetime, there is no point at which old convictions become legally irrelevant.
• High BAC (0.15 or Higher) (§ 49.04(d)): A BAC of 0.15 or above at the time of analysis automatically elevates even a first-offense DWI from a Class B to a Class A misdemeanor. No prior record is required.
• DWI with a Child Passenger (§ 49.045): If a child under 15 was in the vehicle at the time of the offense, the charge becomes a state jail felony regardless of prior record. This enhancement also routinely triggers a parallel Child Protective Services (CPS) investigation alongside the criminal prosecution.
• Intoxication Assault (§ 49.07): Causing serious bodily injury to another person while intoxicated is a third-degree felony. Under Texas law, “serious bodily injury” includes injuries creating a substantial risk of death, permanent disfigurement, or protracted loss of a body part or organ.
• Intoxication Manslaughter (§ 49.08): Causing the death of another person while intoxicated is a second-degree felony, carrying the most severe penalties available under Chapter 49.

The difference between a Class B misdemeanor and a second-degree felony is the difference between county jail and state prison. These enhancements demand immediate, experienced defense from an attorney who knows Collin County’s courts and prosecutors.

Penalties for DWI with Enhancements in Collin County

Each enhancement type carries its own penalty range, and knowing exactly what you face is essential to making informed decisions about your defense. All Collin County misdemeanor and felony criminal cases are prosecuted by the Collin County District Attorney’s Office and heard at the Russell A. Steindam Courts Building in McKinney, Texas, which houses seven County Courts at Law and fifteen District Courts.

Penalty ranges by enhancement category:

• High BAC (0.15 or Higher) - Class A Misdemeanor: Up to one year in county jail, a fine up to $4,000, and license suspension up to two years. An ignition interlock device (IID) is typically required as a condition of bond or probation.
• DWI Second Offense - Class A Misdemeanor (§ 49.09): 30 days to one year in jail, fine up to $4,000, and license suspension up to two years. Even if probation is granted, a mandatory jail term still applies as a condition, ranging from a minimum of 3 days up to 30 days depending on the gap between offenses.
• DWI Third Offense or More - Third-Degree Felony: 2 to 10 years in state prison, fine up to $10,000, and license suspension up to two years.
• DWI with Child Passenger - State Jail Felony (§ 49.045): 180 days to 2 years in a state jail facility, fine up to $10,000. Probation may include mandatory jail time as a condition, and the parallel CPS case proceeds independently.
• Intoxication Assault - Third-Degree Felony (§ 49.07): 2 to 10 years in state prison, fine up to $10,000. Probation may require up to 180 days in jail as a condition.
• Intoxication Manslaughter - Second-Degree Felony (§ 49.08): 2 to 20 years in state prison, fine up to $10,000. If the deceased was the parent of a minor child, Texas Code of Criminal Procedure Article 42.0375 (Bentley’s Law) may require monthly child support restitution payments as part of the sentence.

Beyond criminal penalties, Texas Transportation Code § 709.001 imposes a civil fine on top of any criminal fines for a final DWI conviction: $3,000 for a first conviction, $4,500 for a second or subsequent conviction within a 36-month period, and $6,000 if the BAC was 0.15 or more. Deferred adjudication isn’t available for DWI offenses in Texas, and a felony DWI conviction can’t be expunged or sealed. Additional consequences include SR-22 insurance requirements, employment barriers, professional license jeopardy, and international travel restrictions, including difficulty entering Canada.

Defense Strategies for DWI with Enhancements Cases

Defending against a DWI with enhancements in Texas requires a thorough understanding of both criminal procedure and forensic science. The goal is to identify weaknesses in the prosecution’s evidence before the case gains momentum.

Challenging the Stop & Field Testing

Law enforcement must have reasonable suspicion to initiate a traffic stop. A stop that lacks that foundation can make all subsequent evidence inadmissible. Field sobriety tests present a separate line of challenge: FSTs are subjective and can be influenced by factors unrelated to intoxication, including weather, terrain, footwear, medical conditions, and fatigue.

Contesting Chemical Test Results

Breath and blood test results are frequently challenged in enhanced DWI cases. Key strategies include:

• Breath Test Challenges: Examining whether the breathalyzer was properly calibrated, whether the officer was adequately trained, and whether physiological factors such as mouth alcohol or certain medical conditions could have produced a falsely elevated reading.
• Blood Test Challenges: Scrutinizing the chain of custody for samples, examining lab protocols, and challenging the qualifications of the technicians involved.
• Rising BAC Defense: Arguing that the BAC was below the legal limit while driving and still rising when the test was administered.
• Invalid Search Warrant or Consent: Challenging whether a blood sample was obtained with a valid warrant or truly voluntary consent.

Challenging Vehicle Control & Prior Conviction Records

When a defendant was found in a parked vehicle, the prosecution must prove actual physical control was exercised. This element can be contested depending on the facts. In enhancement cases built on prior convictions, the validity and admissibility of those conviction records can also be challenged directly, potentially removing the basis for an elevated charge.
