Intoxication Assault in Texas — 3rd Degree Felony Charges Explained

The §49.07 statute

Penal Code §49.07 makes it a third-degree felony to cause serious bodily injury to another person by accident or mistake while operating a motor vehicle while intoxicated:

• Punishment: 2 to 10 years TDCJ; up to $10,000 fine
• Enhanced to second-degree felony if victim is peace officer, firefighter, or EMS worker
• Enhanced to second-degree felony if victim suffers traumatic brain injury resulting in vegetative state
• License suspension up to 2 years
• Restitution to victim required
• Permanent felony record
• Deadly weapon finding affects parole calculations

The intoxication element follows Penal Code §49.01 definitions (BAC 0.08+ or loss of normal mental/physical faculties).

"Serious bodily injury" defined

Penal Code §1.07(a)(46) defines "serious bodily injury" as "bodily injury that creates a substantial risk of death or that causes death, serious permanent disfigurement, or protracted loss or impairment of the function of any bodily member or organ."

The threshold is meaningfully higher than ordinary "bodily injury" (which is just physical pain, illness, or any impairment). Examples of serious bodily injury:

• Broken bones requiring surgery
• Internal organ damage
• Permanent scarring or disfigurement
• Traumatic brain injury
• Loss of consciousness with lasting effects
• Spinal injury
• Severe burns
• Loss of bodily function

Cases where the injury is borderline (between bodily injury and serious bodily injury) sometimes resolve at the lower offense level (DWI without intoxication assault) where defense can establish that injuries don't meet the "serious" threshold.

Causation defense

Like intoxication manslaughter, the most contested element is causation. The state must prove that the defendant's intoxicated operation proximately caused the serious bodily injury. Defense angles:

Other-driver causation. Where another vehicle was at fault for the accident, intoxication may not be the proximate cause. Crash reconstruction expert testimony establishes the actual mechanics.

Road conditions and weather. Environmental factors can be intervening causes.

Mechanical failure. Brake, steering, tire issues can cause accidents independently.

Victim conduct. Pedestrian behavior, victim seatbelt use, victim impairment can be relevant.

Foreseeability. The injury must be a foreseeable consequence of the impaired operation. Where the injury occurred from an unusual chain of events, foreseeability arguments may apply.

Defense crash reconstruction experts (often retained at $5,000-$15,000) examine the accident from a defense perspective and often produce reports that materially affect causation analysis.

Plea and trial outcomes

Realistic outcomes for first-time intoxication assault defendants:

Dismissal. Possible with strong causation defense, suppression victory, or where injuries don't meet serious bodily injury threshold.

Reduction to standard DWI. Plea to standard DWI without intoxication assault enhancement. Eliminates the "serious bodily injury" element. Defendants face misdemeanor exposure rather than felony. Available where the case has weakness in the serious bodily injury or causation elements.

Reduction to assault by reckless conduct. Penal Code §22.05 (Deadly Conduct) without intoxication element. Class A misdemeanor or third-degree felony depending on degree of conduct.

Probation on intoxication assault. Available up to 10-year sentences. Conditions are intensive: substantial jail commitment, mandatory treatment, ignition interlock, monitoring, restitution. Felony conviction enters; permanent record.

TDCJ sentence. 2-10 years range. Length depends on circumstances and aggravating factors. First-time defendants typically receive lower end of range; aggravating factors push higher.

Compared to intoxication manslaughter, intoxication assault cases more frequently resolve with probation rather than TDCJ time. The injury severity and circumstances affect this substantially.
