What Is Aggravated DWI in Williamson County, TX
If you've been charged with DWI in Round Rock, Georgetown, or anywhere in Williamson County, you may have heard the term "aggravated DWI", but is it a formal charge under Texas law? It is an informal term for a DWI that is enhanced to a higher offense level due to specific aggravating factors, which carry severe consequences, including felony charges, mandatory jail time, and a permanent record.
Our Round Rock DWI specialist breaks down exactly what those factors are and what they mean for your case.
What Makes a DWI "Aggravated" in Texas?
Texas Penal Code does not use the phrase "aggravated DWI" as a standalone charge. Instead, certain circumstances automatically elevate a standard DWI (beginning as a Class B misdemeanor) to a more serious offense. Texas prosecutors in Williamson County use these enhancements aggressively, and the courts treat them seriously.
The three most common aggravating factors are a high blood alcohol concentration (BAC), a child passenger under 15, and causing serious bodily injury or death while intoxicated.
High BAC: 0.15% or Above
The most common aggravating factor in Texas DWI cases is a BAC of 0.15% or higher, nearly double the legal limit of 0.08%.
A BAC of 0.15% or higher is an aggravating factor that enhances a DWI charge under Texas Penal Code § 49.04(d), converting a first offense from a Class B misdemeanor to a Class A misdemeanor. That single enhancement changes your exposure dramatically:
Courts also commonly require an ignition interlock device (IID) as both a bond condition and a condition of probation when the BAC is 0.15% or above.
It is worth noting that a high BAC increases the charge by one level, so a second-offense DWI is elevated to a third-degree felony when the BAC is 0.15%.

DWI with a Child Passenger Under 15
Driving while intoxicated with a passenger under 15 years old is a separate felony offense, regardless of BAC, under Texas Penal Code § 49.045. This is one of the most serious aggravating factors in Texas DWI law because it is treated as child endangerment even when no accident occurs.
A DWI with a child passenger is a state jail felony in Texas. A conviction can result in a sentence of up to two years in state jail and a fine of up to $10,000.
Beyond the criminal penalties, a conviction for this offense can trigger CPS involvement, loss of custody rights, and a felony record that follows you permanently. In Williamson County, prosecutors pursue these cases with particular aggression.
Intoxication Assault: DWI Causing Serious Bodily Injury
When an intoxicated driver causes serious bodily injury to another person, the charge escalates significantly. Intoxication assault is a third-degree felony under Texas Penal Code § 49.07, punishable by 2 to 10 years in prison.
The prosecution must prove not only that you were intoxicated, but that your intoxication directly caused the injury. This causation element is one of the most important battlegrounds for a skilled defense attorney, particularly when road conditions, other drivers, or mechanical failures contributed to the accident.
Intoxication Manslaughter: DWI Causing Death
If someone dies as a result of intoxicated driving, the charge becomes intoxication manslaughter under Texas Penal Code § 49.08, which is charged as a second-degree felony carrying 2 to 20 years in prison and fines up to $10,000. The charge escalates to a first-degree felony if the victim was a peace officer, firefighter, or EMS professional on duty.
Felony DWI: Third or Subsequent Offense
Prior DWI convictions are themselves an aggravating factor. A third or subsequent DWI is a third-degree felony under Texas Penal Code § 49.09, carrying 2 to 10 years in prison, even if no accident or injury occurred. Texas has no lookback period for prior DWI convictions, meaning a conviction from 20 years ago counts the same as one from last year.

Additional Consequences of an Aggravated DWI Conviction
Beyond prison time and fines, an aggravated DWI conviction in Williamson County can lead to:
- Driver's license suspension: Drivers have only 15 days from the date of arrest to request an ALR (Administrative License Revocation) hearing to contest a license suspension. Missing this window results in an automatic suspension.
- Ignition interlock device (IID): Required in all aggravated DWI cases, installed at the defendant's expense.
- Permanent felony record: An aggravated DWI conviction stays on your Texas criminal record permanently and will appear on background checks. Expunction is generally only available if your case was dismissed, you were acquitted, or you received a pardon. Expunction is not an option for convictions.
- Loss of civil rights: A felony conviction strips you of the right to vote, hold public office, and own a firearm.
- Immigration consequences: Non-citizens may face deportation or inadmissibility following a felony DWI conviction.
Defense Strategies in Aggravated DWI Cases
Aggravating factors increase penalties, but they do not eliminate defenses. An experienced Williamson County DWI defense attorney can challenge an aggravated DWI charge by:
- Challenging the BAC test: Was the breath or blood test properly administered? Was the device calibrated and maintained correctly? Was the chain of custody for a blood sample intact? Testing errors are more common than prosecutors admit.
- Challenging the traffic stop: If the stop violated your Fourth Amendment rights, any evidence obtained may be suppressible, including the BAC result entirely.
- Disputing causation in injury cases: In intoxication assault and intoxication manslaughter charges, the state must prove that your intoxication directly caused the injury or death. Road conditions, mechanical failures, or the actions of other drivers can create reasonable doubt.
- Challenging the child passenger enhancement: Was the minor actually a passenger in the vehicle? Was the vehicle being operated in a public place as required under Texas Penal Code § 49.045?
- Negotiating charge reduction: In some cases, a skilled defense lawyer can negotiate a reduction from a felony to a misdemeanor, or from an aggravated charge to a standard DWI, significantly limiting the long-term impact on your life.
