A minor accident turns into an argument.

The argument escalates—and suddenly you’re accused of using your vehicle as a weapon. Now you’re facing aggravated assault charges, a second-degree felony carrying 2 to 20 years in prison and significant fines. But these cases often come down to interpretation.

What prosecutors claim happened—and what the evidence actually shows—are not always the same. At the Law Offices of Richard C. McConathy, we’ve defended cases just like this and know how to challenge the state’s version of events.

If you’re facing charges, working with an experienced Dallas violent crime lawyer can make a critical difference in your case.

Texas Penal Code §22.02: Aggravated Assault

Aggravated assault is defined in Texas Penal Code §22.02. The statute makes it illegal to commit assault and in the process either cause serious bodily injury or use or display a deadly weapon.

When a motor vehicle is involved, the vehicle can be considered a deadly weapon. This is critical: Texas law recognizes that a vehicle, when used intentionally to cause harm, is a deadly weapon.

The elements are:

  • Intent to cause bodily injury or recklessness. You must have acted with intent to cause bodily injury to another person, or you must have acted with extreme recklessness in a way that demonstrates a conscious indifference to the risk of bodily injury.
  • Bodily injury to another. Your action must have caused bodily injury to at least one other person.
  • Serious bodily injury OR use of a deadly weapon. The assault is aggravated if either: (1) you caused serious bodily injury (defined as an injury that creates a substantial risk of death, disfigurement, or impairment of a body part or organ), or (2) you used or displayed what the state claims was a deadly weapon.
  • Vehicle as deadly weapon. When the vehicle is involved, the state alleges you used the vehicle as a deadly weapon—meaning you used it in a way that could cause serious bodily injury or death.

Understanding “Deadly Weapon” in Motor Vehicle Cases

This is where the charge often becomes unfair. A vehicle is not inherently a deadly weapon. It becomes one only when used in a way that demonstrates intent to cause serious bodily injury or recklessness showing conscious indifference to that risk.

Simply driving your car into someone, even if it causes injury, isn’t automatically aggravated assault. The state must prove you used the vehicle with the required intent or recklessness.

Consider the difference:

Scenario 1: You’re in a traffic argument. The other driver cuts you off. You tap their bumper while trying to move around them. No one is injured. This is a minor traffic violation, not aggravated assault.

Scenario 2: You’re in a traffic argument. You deliberately accelerate and ram another vehicle, causing the driver serious injury. This is aggravated assault.

Scenario 3: You’re in a traffic argument. You drive near another person standing on the sidewalk, and they jump out of the way, terrified. Did you intend to hit them, or were you just angry and driving carelessly? This is a gray area that becomes the centerpiece of your defense.

The state must distinguish between accidents, minor traffic violations, and intentional assaults. We’ll fight to show that what the state characterizes as aggravated assault was actually a traffic incident.

Aggravated Assault vs. Intoxication Assault

There’s another related charge prosecutors often use: intoxication assault under Texas Penal Code §49.07.

Intoxication assault applies when someone operates a vehicle while intoxicated and causes serious bodily injury to another person. It’s a third-degree felony (2-10 years), less serious than aggravated assault, but still a felony.

If you were drinking and a traffic incident caused injury, the prosecutor might charge either aggravated assault or intoxication assault (or both). If your BAC was high, intoxication assault may be the easier charge to prove. If impairment is questionable, the state might lean toward aggravated assault based on intent.

The differences matter:

  • Aggravated Assault: 2-20 years (second-degree felony)
  • Intoxication Assault: 2-10 years (third-degree felony)

If both are charged and you’re convicted, your attorney will push for conviction on the lesser charge.

Common Fact Patterns Leading to Charges

  • Road rage incidents. Two drivers argue, one deliberately uses their vehicle as a weapon. If someone is seriously injured, aggravated assault charges are likely.
  • Traffic arguments that escalate. An accident happens. Words are exchanged. Someone gets angry and drives toward the other person. Even if contact is minimal, charges can follow.
  • Accidents where the victim claims intentionality. A traffic accident occurs. The victim claims the driver deliberately hit them to cause injury. If serious injury resulted, aggravated assault may be charged.
  • DWI-related incidents. An impaired driver causes a traffic accident with serious injury. The charge might be intoxication assault if impairment is clear, or aggravated assault if the prosecution wants to allege intentional conduct.
  • Hit-and-run situations. A driver hits someone and flees. The victim claims it was intentional. The driver claims it was an accident. The charge depends on what the evidence shows.

What the Prosecution Must Prove

To convict you of aggravated assault with a motor vehicle, the state must prove every element beyond a reasonable doubt.

  • First, you intentionally or recklessly caused bodily injury to another person. This is the critical element. The prosecution must prove either that you deliberately intended to cause injury or that you acted with extreme recklessness—meaning you consciously disregarded a substantial risk of bodily injury. Simple negligence or carelessness isn’t enough. There must be intent or extreme recklessness.
  • Second, you caused serious bodily injury or used a deadly weapon.If no serious injury resulted, the charge can’t stand (it would be simple assault, a misdemeanor). If serious injury did result, the state has met this element. If a vehicle is involved, the state will argue the vehicle was a deadly weapon.
  • Third, the vehicle was used or displayed as a deadly weapon. This is where we fight hard. Was the vehicle truly used as a deadly weapon? Or was it a traffic incident where injury resulted? These are very different things.

Your Defense: Challenging the Charge

Challenge whether the vehicle was a deadly weapon. A vehicle is a deadly weapon only if used in a manner capable of causing serious bodily injury or death and the defendant knew or should have known of that capability. If you were merely driving carelessly or in a minor traffic incident, the vehicle wasn’t used as a deadly weapon.

Challenge the intent element. Did you intend to cause bodily injury? If you were merely angry and driving carelessly, that’s not the same as intending to harm. We’ll present evidence that you didn’t intend to cause injury.

Challenge the recklessness element. Even if you drove carelessly, was your conduct so reckless as to demonstrate conscious indifference to a substantial risk of bodily injury? Negligent driving isn’t reckless enough.

Challenge the causation. Did your vehicle actually cause the injury claimed? Sometimes the victim’s account is exaggerated or inaccurate. We’ll investigate the accident, obtain medical records, and determine what injuries actually resulted from the traffic incident versus other causes.

Challenge the credibility of the complainant. In road rage cases, both parties are emotional. The alleged victim may have initiated the confrontation or exaggerated what happened. We’ll examine the alleged victim’s credibility and presentation.

Request accident reconstruction. If the case goes to trial, we may hire an accident reconstruction expert who can provide testimony about the mechanics of the incident, vehicle speeds, sight lines, and how the accident occurred.

How These Cases Develop

  1. After the incident, police are called and respond. They interview both drivers and take statements. If anyone is seriously injured, this is treated more seriously.
  2. Police report. Officers document the incident, statements, and any injuries. The report determines whether charges are likely.
  3. Investigation. Detectives may follow up, interview witnesses, and gather evidence.
  4. Charging decision. The prosecutor decides whether to charge based on the police report and investigation.
  5. Arrest and booking. If charges are filed, the defendant is arrested, booked, and bail is set.
  6. First appearance. The defendant appears before a magistrate, is advised of rights, and bail is set.
  7. Discovery. Both sides exchange evidence—police reports, photos, medical records, statements.
  8. Motion practice. The defense may file motions challenging the evidence or requesting disclosure.
  9. Plea negotiations. The state may offer a plea deal (reduction to simple assault, misdemeanor, or lesser felony).
  10. Trial or acceptance of plea. The case either goes to trial or is resolved through a plea agreement.

Bail and Release Conditions

Aggravated assault is a serious felony. Bail is typically set higher than for misdemeanors, but it’s not always unaffordable.

For a first-time offender with stable employment and no criminal history, bail might be $5,000-$15,000. This allows for release on a personal bond or with a bail bondsman.

For someone with prior arrests or convictions, bail might be higher—$25,000 or more.

If weapons were involved or if the alleged victim was seriously injured, bail might be denied entirely, and the defendant held without bail pending trial.

We work to get bail reduced if it’s set too high. Factors we emphasize: stable employment, ties to the community, no flight risk, and no history of violence.

Plea Negotiations

Many aggravated assault cases are resolved through plea agreements rather than trial.

  • Reduction to simple assault (misdemeanor): If the injury is less serious than claimed or if the state’s evidence of a deadly weapon is weak, prosecutors may agree to reduce to simple assault. This avoids a felony conviction.
  • Reduction to a lesser felony: The state might agree to reduce from aggravated assault (2-20 years) to intoxication assault (2-10 years) if impairment is clear and intent is questionable.
  • Plea to lesser included offense: You might plead to recklessness causing injury rather than intentional assault.
  • Probation: In some cases, especially first offenses with minimal injury, the prosecutor might agree to probation instead of prison time.

Any plea agreement must be carefully evaluated. We want to ensure you understand the consequences and that the plea is truly in your interest.

Trial Strategy

If the case goes to trial, our strategy focuses on attacking the state’s proof of the critical elements.

Challenging intent: We’ll present evidence that you didn’t intend to cause injury—maybe you were trying to get away from a confrontation, not deliberately hit the other person.

Challenging recklessness: We’ll show that your conduct, while perhaps negligent, didn’t rise to the level of recklessness requiring conscious indifference to a substantial risk of injury.

Challenging the “deadly weapon” classification: We’ll argue that the vehicle was used ordinarily and wasn’t employed as a deadly weapon.

Presenting the accident reconstruction: We’ll present expert testimony about how the accident occurred, vehicle speeds, and whether intentional conduct was possible given the mechanics.

Examining medical evidence: We may challenge the seriousness of the injuries or present evidence that the injuries were caused by factors other than the alleged assault.

Cross-examination: We’ll thoroughly cross-examine police officers and the alleged victim about inconsistencies and questionable accounts.

Collateral Consequences

Beyond the prison sentence and fines, a conviction carries serious collateral consequences.

Felony record: A felony conviction creates a permanent criminal record affecting employment, housing, licensing, and background checks.

Job loss: Many employers won’t hire someone with a violent felony conviction. Professional licenses may be lost.

Driving record: The incident becomes part of your driving record, affecting insurance and future employment in transportation fields.

Gun rights: A felony conviction means you lose the right to own or possess firearms in Texas.

Immigration: If you’re not a U.S. citizen, conviction may trigger deportation proceedings.

Child custody: If you have children, a violent felony conviction can affect custody and visitation rights.

Common Mistakes in These Cases

  • Admitting fault immediately. Many people apologize or acknowledge hitting the other person, thinking it will help. These statements are used as evidence of intent. Never admit anything without consulting a lawyer.
  • Talking to police without a lawyer. Any statement you make can be used against you. Remain silent and request a lawyer.
  • Accepting the first bail offer. Bail can often be reduced or modified. We’ll request a bail reduction hearing if the initial bail is too high.
  • Failing to challenge the “deadly weapon” characterization. This is where many convictions are vulnerable. If we can show the vehicle wasn’t used as a deadly weapon, the charge should be reduced.
  • Not obtaining an accident reconstruction expert. Mechanical details matter. A reconstruction expert can provide crucial testimony about vehicle speeds, impact points, and whether intentional conduct was even possible.
