Aggravated assault by vehicle while DUI in Pennsylvania is a second-degree felony that carries up to ten years in state prison and a fine of up to $25,000 per count. The charge applies when a driver violates Pennsylvania’s DUI statute and, through negligent driving, causes serious bodily injury to another person. It sits on top of the DUI itself, and the diversion program that resolves many first-time DUI cases is not available.
What the Prosecution Has to Prove
Under 75 Pa. C.S. § 3735.1, prosecutors have to establish two elements: that the driver violated Pennsylvania’s DUI law under Section 3802, and that the DUI violation caused serious bodily injury to another person.1Pennsylvania General Assembly. Pennsylvania Code 75 3735.1 – Aggravated Assault by Vehicle While Driving Under the Influence The statute requires negligent conduct. Being over the legal limit is not enough on its own; the driving itself must fall below what a reasonable sober driver would do.
Serious bodily injury is defined in Pennsylvania law as injury that creates a substantial risk of death, causes serious permanent disfigurement, or produces extended loss or impairment of any bodily function.2Pennsylvania General Assembly. Pennsylvania Code 18-2301 – Definitions A broken arm that heals normally probably would not qualify. A traumatic brain injury, spinal damage, or loss of a limb almost certainly would.
Causation is where these cases are usually contested. The Commonwealth cannot simply point to a BAC over the limit and an injured victim. It has to show the DUI violation actually produced the injury. The Superior Court took up that question in Commonwealth v. Spotti, where a panel initially reversed convictions on causation grounds before the full court granted reargument.3Justia. Commonwealth v. Spotti, R. To make the link, prosecutors typically use accident reconstruction, toxicology, and witness testimony, along with driving behavior like running a red light, excessive speed, or drifting across lanes.
Prison Time, Fines, and Restitution
As a second-degree felony, the offense carries a maximum of ten years in prison.4Pennsylvania General Assembly. Pennsylvania Code 18 1103 – Sentence of Imprisonment for Felony Fines can reach $25,000 per count.5New York Codes, Rules and Regulations. Pennsylvania Code 18 1101 – Fines When more than one person is seriously hurt in the same crash, each victim can support a separate count, and judges have discretion to run those sentences consecutively.
Pennsylvania previously imposed a mandatory minimum under 42 Pa. C.S. § 9718.4. Pennsylvania courts have struck that provision down as unconstitutional in its entirety following the U.S. Supreme Court’s decision in Alleyne v. United States, which held that facts increasing a mandatory minimum must be found by a jury beyond a reasonable doubt. Sentencing now falls within the judge’s discretion, guided by Pennsylvania’s sentencing guidelines, the severity of the injuries, the defendant’s criminal history, and the circumstances of the crash.
A defendant convicted under § 3735.1 who was also driving without a license or on a suspended license faces up to two additional years on top of any other penalty.1Pennsylvania General Assembly. Pennsylvania Code 75 3735.1 – Aggravated Assault by Vehicle While Driving Under the Influence
Restitution to victims for medical bills, lost wages, and other financial harm is routine. Courts also order alcohol highway safety school and substance abuse treatment. Probation after release typically includes random drug and alcohol testing, employment conditions, and travel restrictions, and a violation can send someone back to prison.
License Suspension and Interlock
A conviction triggers an automatic one-year suspension of driving privileges under 75 Pa. C.S. § 1532(a).6Pennsylvania General Assembly. Pennsylvania Code 75 1532 – Suspension of Operating Privilege That suspension runs separately from any administrative penalty tied to the underlying DUI, so the total time off the road can stack.
After the suspension, PennDOT restoration requires a restoration fee, proof of insurance, and, because this is a DUI-related suspension, an ignition interlock restricted license period of at least one year.7Pennsylvania General Assembly. Pennsylvania Code 75 3805 – Ignition Interlock The device must be installed on any vehicle the driver operates, and removal requires vendor certification of compliance.8Pennsylvania Department of Transportation. Pennsylvania Ignition Interlock Law Monthly lease and maintenance fees generally run $70 to $125. Repeat DUI-related offenses can lead to indefinite revocation, with reinstatement only by petition to PennDOT.
Why ARD Isn’t an Option
Pennsylvania’s Accelerated Rehabilitative Disposition program, the diversion route that lets some first-time DUI offenders avoid a conviction, is not available for this charge. Under 75 Pa. C.S. § 3807, ARD is barred when an accident connected to the DUI caused serious bodily injury or death to anyone other than the defendant. Because serious bodily injury is an element of § 3735.1, every person charged under this statute is disqualified automatically. Prosecutors have no discretion to admit someone to ARD on this offense.
Consequences That Outlast the Sentence
The Record Doesn’t Go Away
A second-degree felony conviction is permanent. Pennsylvania’s expungement statute allows felony convictions to be expunged only after an unconditional pardon from the governor, or when the person reaches age 70 and has been arrest-free for ten years after completing the sentence.9Pennsylvania General Assembly. Pennsylvania Code 18 9122 – Expungement Pardons are slow and rare. In practice the conviction stays on the record for life, showing up on background checks for jobs, housing, and professional licensing. Employers in driving, healthcare, education, law enforcement, and finance regularly screen out felony DUI-related convictions, and Pennsylvania licensing boards may deny, suspend, or revoke licenses in nursing, teaching, law, and other regulated fields.
FAA-Licensed Pilots
Anyone holding an FAA certificate must report a DUI-related motor vehicle action, including a conviction or a license suspension, to the FAA within 60 days.10eCFR. 14 CFR 61.15 – Offenses Involving Alcohol or Drugs Missing the deadline is a separate violation that can lead to denial of certificate applications for up to a year or suspension of an existing certificate. A felony DUI conviction involving serious bodily injury will draw significant scrutiny at any subsequent medical certificate application, and a second alcohol-related motor vehicle action within three years is grounds for certificate revocation.
Civil Lawsuits and Insurance
Victims frequently sue for medical expenses, lost income, and pain and suffering. Civil cases use a lower standard of proof than criminal cases, so a plaintiff can win a civil judgment even if the criminal case ends in acquittal. Pennsylvania courts have recognized that driving while intoxicated can qualify as outrageous conduct showing reckless indifference to others’ safety, which supports punitive damages on top of compensatory damages.
Insurance often will not cushion the blow. Many auto policies exclude bodily injury or property damage arising from intentional or criminal acts. Where an exclusion applies, the insurer denies coverage and the defendant is personally responsible for the full judgment. Punitive damages are generally not insurable regardless of policy language.
Where Cases Get Fought
Attacking Causation
Because the Commonwealth has to prove the DUI violation caused the injury, defense attorneys often build the case around alternative explanations: road conditions, mechanical failure, another driver’s actions, or the victim’s own conduct. Reasonable doubt on causation defeats the § 3735.1 charge even if the underlying DUI stands.
Contesting the Chemical Test
Pennsylvania has strict rules for collecting, handling, and testing blood and breath samples. Breathalyzer calibration records, blood sample chain of custody, and lab procedures are all open to challenge. If equipment was out of calibration, samples were mishandled, or required procedures were skipped, BAC results may be suppressed, and proving the DUI element becomes substantially harder.
Constitutional Challenges
Evidence from an unlawful traffic stop or arrest can be suppressed under the Fourth Amendment. If officers lacked reasonable suspicion for the stop or probable cause for the arrest, field sobriety tests, breath tests, and blood draws may all be excluded. Blood draws carry their own issues. In Mitchell v. Wisconsin, the U.S. Supreme Court held that police can generally conduct warrantless blood draws on unconscious DUI suspects under the exigent circumstances exception, while leaving open the possibility that a defendant could show no legitimate basis for a warrantless draw in an unusual case. A successful suppression motion can force a dismissal or a significant reduction in charges.
