Vehicular assault under RCW 46.61.522 is a Class B felony in Washington, punishable by up to ten years in prison and a $20,000 fine when a driver causes substantial bodily harm to another person by driving under the influence, driving recklessly, or driving with disregard for the safety of others.1Washington State Legislature. RCW 46.61.522 – Vehicular Assault—Penalty The statutory maximum is only part of the story. What a defendant actually faces depends on which of the three theories the state uses, the severity of the victim’s injuries, and the defendant’s criminal history as scored on Washington’s sentencing grid.
The Three Ways the State Can Charge It
Prosecutors can proceed under any of three theories, and they only need to prove one.1Washington State Legislature. RCW 46.61.522 – Vehicular Assault—Penalty
- Driving under the influence of alcohol or any drug, as defined by RCW 46.61.502. Washington’s per se limits are a blood alcohol concentration of 0.08 or a THC concentration of 5.00 nanograms per milliliter of blood, but prosecutors can also prove impairment through observed behavior, field sobriety tests, and toxicology even when the driver is below those numbers.
- Driving in a reckless manner, which Washington courts have defined as driving in a rash or heedless way, indifferent to the consequences. This is more than ordinary carelessness. Extreme speeding, weaving through traffic at high speed, and street racing are the typical fact patterns.
- Driving with disregard for the safety of others. This is a lower bar than recklessness and covers situations where the driver failed to recognize a risk that a reasonable person would have noticed, such as running a red light while distracted.
The theory the state chooses matters at sentencing because the DUI and reckless prongs sit a full seriousness level higher on the grid than the disregard prong.
What Counts as Substantial Bodily Harm
The felony only applies if the victim’s injuries meet the “substantial bodily harm” definition in RCW 9A.04.110. That statute recognizes three categories:2Washington State Legislature. RCW 9A.04.110 – Definitions
- Temporary but substantial disfigurement, such as deep lacerations, significant scarring, or facial damage that changes appearance for a meaningful period.
- Temporary but substantial loss of bodily function, such as a knee injury that prevents walking for months or a head injury that disrupts cognitive function.
- A fracture of any body part. Any broken bone qualifies, which is why this is the easiest category for prosecutors to prove.
Bruises, minor cuts, and soft-tissue strains that heal quickly generally do not reach this threshold and would more likely support a lesser charge like negligent driving. Defense attorneys regularly challenge the injury evidence by scrutinizing medical records and presenting competing expert testimony about whether disfigurement or functional loss was truly substantial.
Standard Sentencing Ranges
Washington judges sentence from a grid that combines the offense’s seriousness level with the defendant’s offender score. Vehicular assault by DUI or recklessness is a Seriousness Level IV offense. Vehicular assault by disregard for the safety of others is Seriousness Level III, which reflects the lower degree of culpability.3Washington State Legislature. RCW 9.94A.515 – Table 2
For Seriousness Level IV, the standard ranges run as follows:4Washington State Legislature. RCW 9.94A.510 – Table 1—Sentencing Grid
- Offender score 0: 3 to 9 months
- Offender score 1: 6 to 12 months
- Offender score 2: 12+ to 14 months
- Offender score 3: 13 to 17 months
- Offender score 4: 15 to 20 months
- Offender score 5: 22 to 29 months
- Offender score 6: 33 to 43 months
- Offender score 7: 43 to 57 months
- Offender score 8: 53 to 70 months
- Offender score 9 or more: 63 to 84 months
A first-time offender with no criminal history and a Level IV conviction faces 3 to 9 months in the standard range. The ten-year statutory maximum and $20,000 fine remain the ceiling throughout.5Washington State Legislature. RCW 9A.20.021 – Maximum Sentences for Crimes Committed July 1, 1984, and After
How the Offender Score Is Counted
The offender score drives the range, and the way Washington counts prior traffic felonies is harsher than for most other crimes. Under RCW 9.94A.525, each prior conviction for vehicular assault or vehicular homicide counts as two points, not one.6Washington State Legislature. RCW 9.94A.525 – Offender Score Other prior adult felonies count one point each, and juvenile felonies count half a point.
Prior serious traffic offenses such as reckless driving or hit-and-run with injury add one point per adult conviction. A prior conviction for operating a vessel while intoxicated adds a point. Even a deferred prosecution for a second or subsequent DUI adds a point. Two prior vehicular assaults alone put a defendant at four points before any other history is counted, which pushes the standard range to 15 to 20 months or more.
Going Above the Standard Range
Judges generally must sentence within the grid. RCW 9.94A.535 allows an exceptional sentence above the range when specific aggravating factors are proven.7Washington State Legislature. RCW 9.94A.535 – Exceptional Sentences In vehicular assault cases, the ones that come up most often are:
- A particularly vulnerable victim, where the defendant knew or should have known about the vulnerability.
- Deliberate cruelty, which in a vehicular context often involves fleeing the scene and leaving an injured person without aid.
- Unscored criminal history, meaning prior misdemeanor or out-of-state convictions excluded from the offender score that make the standard range clearly too lenient.
With the exception of factors tied to criminal history, aggravators must be found by a jury beyond a reasonable doubt, and the prosecution has to give advance notice that it intends to seek an exceptional sentence. If the jury finds the factor, the judge can go up to the ten-year maximum.
License Revocation and Ignition Interlock
A conviction triggers a mandatory one-year driver’s license revocation through the Department of Licensing, separate from the criminal sentence.8Washington State Legislature. RCW 46.20.285 – Offenses Requiring Revocation The clock is tolled during any incarceration, so a 12-month prison term effectively means two years or more without a license.
If the arrest involved a refusal to take a breath or blood test, administrative penalties can hit before any conviction. A first refusal within seven years brings a one-year revocation. A second or later refusal within seven years brings a two-year revocation.9Washington State Legislature. RCW 46.20.3101 – Implied Consent Revocation These administrative revocations run on a separate track and can take effect even if the criminal charge is later reduced or dismissed.
The Department of Licensing also lists vehicular assault among the offenses that can trigger an ignition interlock device requirement, especially when the charge involves alcohol or drugs or when a vehicular assault is amended down to reckless or negligent driving as part of a plea.10Washington State Department of Licensing.

Mandatory Restitution
Restitution is effectively mandatory. Under RCW 9.94A.753, the court must order it whenever a conviction causes injury, unless extraordinary circumstances make it inappropriate and the judge explains those circumstances on the record.11Washington State Legislature. RCW 9.94A.753 – Restitution Vehicular assault turns on injury by definition, so judges almost always order it.
Restitution covers actual losses: medical bills, rehabilitation, lost wages, and property damage. Amounts can be substantial because serious injuries often involve long hospital stays and extended recoveries, and the total frequently dwarfs the criminal fine.
Community Custody After Release
After prison, Washington imposes a period of community custody, the state’s version of supervised release. Standard conditions under RCW 9.94A.703 include reporting to a community corrections officer, disclosing changes in address or employment, avoiding controlled substances, and paying supervision fees.12Washington State Legislature. RCW 9.94A.703 – Community Custody—Conditions
Courts regularly add crime-specific conditions for vehicular assault:
- Substance abuse treatment or counseling
- Total abstention from alcohol and drugs
- Community service
- No contact with the victim
- Geographic restrictions
- Payment of all legal financial obligations, including restitution
A violation can bring sanctions up to and including confinement. On a DUI-based conviction, the no-alcohol condition is close to automatic, and a single positive test can send someone back into custody.
Common Defenses
Most vehicular assault defenses target the causal link between the driving and the injury. Washington recognizes an intervening and superseding cause: if something entirely outside the defendant’s control broke the chain, the charge can fail. The bar is high. The other driver’s conduct or a mechanical failure has to be the kind of event that would have caused the crash regardless of what the defendant did.
In most crashes multiple factors contribute, and Washington law does not require the defendant’s conduct to be the sole cause. A concurring or contributing cause from another driver does not block a conviction. If the defendant was impaired and another driver was also negligent, the defendant can still be convicted as long as the impaired driving was a proximate cause of the harm.
Other defense work goes to the elements. In DUI-based cases, that often means challenging blood or breath test reliability, the legality of the traffic stop, or the officer’s basis for suspecting impairment. In reckless-driving cases, the defense may argue the driving fell short of being rash, heedless, and indifferent to consequences. And in every case, the defense can push on whether the victim’s injuries truly qualify as substantial bodily harm, aiming for a reduction to a lesser offense.
Collateral Consequences
A Class B felony follows a person long after the sentence ends. The right to possess firearms is lost. Professional licenses in healthcare, education, law, and many other fields can be denied, suspended, or revoked. Background checks will show the conviction, and many employers treat a violent felony as disqualifying regardless of the facts.
Insurance is another pressure point. Many auto policies contain criminal acts exclusions that can let the insurer deny coverage for damages tied to the incident. If that exclusion applies, the defendant becomes personally liable for the victim’s civil damages on top of any court-ordered restitution. Combined with fines, lost earning capacity, and the ongoing effects of a felony record, the financial fallout of a vehicular assault conviction often exceeds the cost of the prison term itself.
