What Is Homicide by Vehicle in Pennsylvania?
Although commonly referred to as “Vehicular Homicide”, Pennsylvania law uses the term “homicide by vehicle”. The law is defined under 75 Pa. C.S. § 3732.
A person may be charged when:
- They violate a traffic law (other than DUI), and
- That violation is the cause of another person’s death
This is not an intentional crime. The prosecution does not need to prove that the driver meant to harm anyone.
Instead, the case centers on:
- Whether a traffic violation occurred, and
- Whether that violation directly caused the fatal accident
How It Differs from Homicide by Vehicle While DUI
Pennsylvania law separates these into two distinct offenses:
Homicide by Vehicle
- Based on a traffic violation (e.g., reckless or negligent driving)
- Typically charged as a felony of the third degree
Homicide by Vehicle While DUI
- Involves alleged impairment by alcohol or drugs
- Charged as a felony of the second degree
- Carries significantly more severe penalties
This distinction is critical, because the type of evidence—and the defense strategy—changes dramatically depending on the charge.
What the Prosecution Must Prove
To convict, the prosecution must prove all three of the following:
Step 1.
A Traffic Violation Occurred
- Reckless driving
- Speeding
- Failure to obey traffic signals
- Other violations of Pennsylvania vehicle law
Step 2.
The Violation Was More Than Minor
- Reckless, or
- Grossly negligent
Step 3.
Causation of Death
This is the most important—and most contested—element. The prosecution must prove that:
The alleged violation was a direct and substantial factor in causing the fatality
Penalties for Homicide by Vehicle
A conviction can result in serious consequences, including:
- Felony record
- Prison sentence
- Significant fines
- Driver’s license suspension
Additional factors—such as multiple victims or prior offenses—can increase the severity of the outcome.
How These Cases Are Actually Built
While the charge may sound straightforward, these cases are rarely simple.
But these pieces of evidence are not always as clear or reliable as they may appear.
Where Homicide by Vehicle Cases Are Challenged
The outcome of a case often depends on whether the evidence holds up under scrutiny. These cases often come down to a few critical weaknesses in the prosecution’s case.
Even if a traffic violation occurred, that does not automatically mean it caused the death. Key questions include:
- Was the accident avoidable?
- Did another driver contribute to the crash?
- Were road or environmental conditions a factor?
If causation cannot be clearly established, the charge may not stand.
Reconstruction is based on:
- Assumptions
- Calculations
- Interpretation of physical evidence
Small errors in analysis can lead to very different conclusions about:
- Speed
- Timing
- Driving behavior
In cases involving alleged impairment, the prosecution may rely on:
- Blood alcohol testing
- Drug concentration levels
But these tests raise important issues:
- Whether levels actually indicate impairment at the time of the crash
- Timing of the sample vs. time of driving
- How substances affect individuals differently
Why These Cases Require a Different Approach
Homicide by vehicle cases are not handled the same way as standard traffic or DUI charges.
They involve:
- Felony-level consequences
- Technical evidence
- Complex questions of causation
In many cases, the defense is not about disputing that an accident occurred—it is about examining whether the legal standard for criminal liability has truly been met.
Frequently Asked Questions
Yes. It is typically charged as a felony of the third degree, though related charges (such as DUI-based offenses) may carry higher penalties.
Intent is not required. The focus is on whether a traffic violation occurred and whether it caused the death.
In some cases, yes—particularly where causation is unclear or the evidence is disputed.
“Vehicular homicide” is a general term. In Pennsylvania, the formal charge is “homicide by vehicle,” which has specific statutory elements.

What to Do If You Are Facing Charges
If you are under investigation or have been charged:
- Do not discuss the case with police without legal representation
- Avoid making statements that could later be used against you
- Seek legal guidance as early as possible
Early decisions can affect how evidence is preserved, analyzed, and challenged.
