Aggravated vehicular assault is not simply a more serious version of a first-time vehicular assault. Tennessee uses the offense to address impaired-driving cases involving serious bodily injury when the accused also has specified prior alcohol-related convictions or an exceptionally high alcohol concentration combined with a prior DUI or boating-under-the-influence conviction. That history becomes an element the State must prove in a separate count.
Kevin Kennedy represents people facing serious DUI-related felonies in Nashville and Middle Tennessee. In an aggravated vehicular assault case, the defense must examine two different layers of proof: whether the State can establish vehicular assault in the current crash, and whether the prior convictions or blood-alcohol facts legally satisfy the aggravating statute.
How Aggravated Vehicular Assault Is Defined
Tenn. Code Ann. § 39-13-115 builds aggravated vehicular assault on top of vehicular assault under § 39-13-106. Vehicular assault requires proof that intoxication proximately resulted in reckless operation of a motor vehicle or qualifying vessel that caused serious bodily injury to another person.
Aggravated vehicular assault then requires an additional statutory factor. One route is two or more prior DUI or boating-under-the-influence convictions. Another is at least one prior conviction for vehicular assault, intoxication-based vehicular homicide, or aggravated vehicular homicide. A separate route applies when the defendant had an alcohol concentration of 0.20% or more at the time of the offense and one prior DUI or boating-under-the-influence conviction.
Prior Convictions Are Part of the Case
Unlike ordinary sentencing history, the qualifying prior convictions are part of the aggravated-vehicular-assault framework itself. Section 39-13-115 requires the indictment to specify the prior conviction or convictions in a separate count and provide notice of them.
If the jury first convicts the defendant of vehicular assault, the aggravating facts are then considered separately. That structure matters because the defense can challenge whether a prior offense legally qualifies, whether it falls within the statutory twenty-year definition of prior conviction, and whether the State has the required certified proof.
The Current Crash Still Must Qualify as Vehicular Assault
A prior record does not substitute for proof of the present offense. The State must still prove intoxication, reckless conduct, serious bodily injury, and proximate causation in the current crash.
Crash reconstruction, road conditions, actions of other drivers, mechanical issues, witness accounts, vehicle data, body-worn camera footage, blood or breath evidence, and medical records may all affect whether the present case actually satisfies § 39-13-106.
Serious Bodily Injury Can Be Contested
Aggravated vehicular assault requires the same serious-bodily-injury element as vehicular assault. Tennessee gives that phrase a specific statutory meaning, and not every painful or significant injury necessarily qualifies.
Hospital records, imaging, surgery, duration of impairment, risk of death, disfigurement, loss of bodily function, and expert testimony can become central. The defense should examine whether the medical proof supports the legal definition rather than relying on the seriousness of the collision alone.
The 0.20% Aggravator Requires Careful Testing Review
One route to aggravated vehicular assault requires an alcohol concentration of 0.20% or more at the time of the offense plus one qualifying prior DUI or BUI conviction. Because the threshold is tied to the time of the offense, the timing and reliability of chemical testing can be especially important.
Blood-draw warrants, chain of custody, laboratory procedures, hospital samples, breath-machine records, calibration, contamination concerns, and retrograde-extrapolation assumptions should all be examined when the State relies on a very high alcohol concentration.
Classification and Sentencing Exposure
Aggravated vehicular assault is a Class C felony. Tennessee’s general sentencing statute authorizes three to fifteen years for a Class C felony, with the applicable sentencing range depending on the person’s record and other sentencing rules. Section 39-13-115 also requires a fine of at least $5,000 and no more than $15,000.
The conviction also results in a driving prohibition under the vehicular-assault license provisions. Those consequences are in addition to the ordinary collateral effects of a serious felony conviction.
Causation Is Often More Complicated Than the Police Report Suggests
An impaired driver can be criminally liable only if the required causal connection is proven. A serious collision may involve speeding by another vehicle, an unsafe turn, poor lighting, weather, road design, unexpected pedestrian conduct, or other contributing causes.
The defense should separate evidence of intoxication from evidence of causation. The presence of alcohol or drugs does not automatically establish that intoxication proximately caused the serious bodily injury.
Defense Strategy in an Aggravated Vehicular Assault Case
The defense may challenge the legality of the stop or seizure, intoxication, the reliability of chemical testing, recklessness, serious bodily injury, proximate causation, the identity of the driver, or the legal sufficiency of the alleged prior convictions.
Kevin approaches these cases by separating the current crash from the enhancement evidence. That makes it possible to test each part of the State’s theory independently rather than allowing the prior record to dominate the case from the beginning.
