Not Every Tragedy Is a Crime: Providing Fearless Advocacy for the Accused in Vehicular Homicide Cases

Deadly accidents can happen without criminal intent. A driver might make a quick decision, face an unexpected road hazard, or be caught in circumstances beyond their control, and someone loses their life as a result of a collision.

Drivers involved in fatal crashes may be surprised to find themselves facing felony charges, but a charge is not the same as a conviction. To convict you, the prosecution must prove every element of the applicable offense beyond a reasonable doubt. A tragic outcome alone does not meet that burden. In a non-DUI homicide by vehicle case, ordinary negligence by itself does not satisfy the statute’s requirement of recklessness or gross negligence.

At Brennan Law Offices, we understand the weight you may be carrying: grief, regret, fear, and uncertainty about your future. Many people facing these charges are not criminals. They are ordinary drivers caught in a terrible moment. They deserve a thorough, experienced defense, no matter the circumstances.

Our firm's commitment is clear: we examine the prosecution's case, challenge what we can, and pursue the strongest defense based on the facts. You are presumed innocent. We build our defense on that fundamental right.

Two Statutes, Serious Consequences: How Pennsylvania Defines and Classifies Vehicular Homicide

Pennsylvania’s vehicular homicide laws address deaths caused through specified unlawful driving conduct rather than an intent to kill. The precise requirements differ depending on whether DUI is alleged. Pennsylvania separates vehicular homicide into two principal offenses. Neither charge requires proof that the driver intended to kill anyone, but the Commonwealth must prove more than the fact that a fatal collision occurred.

Homicide by Vehicle Under 75 Pa.C.S. § 3732

A non-DUI homicide by vehicle charge generally requires the prosecution to prove that the driver met all of the following conditions:

• Acted recklessly or with gross negligence
• Violated a state law or local ordinance governing vehicle operation or traffic
• Caused another person’s death through that violation

The qualifying traffic violation might involve allegations such as reckless driving, unlawful speed, distracted driving, disregarding a traffic signal, or crossing into another lane.

The prosecution must connect the alleged violation and the required level of culpability to the death. A tragic mistake, standing alone, does not necessarily satisfy that standard.

Homicide by vehicle under 75 Pa.C.S. § 3732 is generally a third-degree felony, carrying a maximum sentence of seven years in prison and a fine of up to $15,000 for each count. Certain statutorily identified circumstances may permit additional imprisonment, including some offenses involving an active work zone, driving without a valid license or while suspended, handheld device use, or failure to comply with requirements involving emergency vehicles.

Homicide by Vehicle While DUI Under 75 Pa.C.S. § 3735

Homicide by vehicle while driving under the influence is a separate and even more serious offense charged under 75 Pa.C.S. § 3735. This charge applies when the prosecution alleges that a person unintentionally caused a death as a result of violating Pennsylvania’s DUI law, 75 Pa.C.S. § 3802, and the person is convicted of that DUI offense.

The baseline offense is generally a second-degree felony and carries a mandatory minimum sentence of three years for each person killed. The mandatory terms must be imposed consecutively when more than one death is involved. Qualifying prior DUI or serious traffic history and certain aggravated circumstances can increase the offense to a first-degree felony and produce higher mandatory minimum sentences.

Because Pennsylvania substantially amended § 3735 in 2025, the precise grading and minimum sentence must be determined from the current statute and the accused person’s actual record rather than from older summaries of the law.

With decades of experience representing people accused of violations ranging from traffic violations and DUI to the most serious felony offenses, including murder and violent crimes, we have the experience and resources to address the complex factual, scientific, and legal issues that can arise in a vehicular homicide case. We understand what’s at stake, and we can draw on our criminal defense experience to evaluate the available defenses, potential resolutions, and sentencing exposure relevant to each client’s unique situation.

DUI-Related vs. Non-DUI Vehicular Homicide: A Distinction That Can Shape Your Defense

Whether someone died in a crash is not the only factor that matters in a vehicular homicide case. One of the most important questions is which legal theory the Commonwealth is using to hold the driver criminally responsible.

In a non-DUI prosecution, the central disputes may include:

• Whether the driver committed the alleged traffic violation
• Whether the conduct amounted to recklessness or gross negligence rather than ordinary negligence
• Whether that violation actually caused the death
• Whether another driver, roadway condition, mechanical problem, medical event, or other intervening circumstance contributed to the collision

In a DUI-related prosecution, the defense must also examine whether the Commonwealth can prove the underlying DUI offense and the required causal connection between that violation and the death. Depending on the DUI theory, that may involve alcohol concentration, alleged drug use, claimed impairment, prescription medication, toxicology interpretation, or the timing of consumption and testing.

The applicable charge determines what the defense must test. A § 3732 case may turn heavily on culpability and the alleged traffic violation, while a § 3735 case requires close examination of the underlying DUI evidence as well as causation.

The Vehicular Homicide Investigation Phase: What Happens in the Hours and Days After a Fatal Crash

A vehicular homicide case often begins as an investigation rather than an immediate arrest. While emergency personnel are responding, police may begin documenting the scene, separating witnesses, photographing vehicle positions, obtaining video, inspecting roadway conditions, and deciding whether alcohol or drugs may have been involved.

The driver may be asked to explain what happened while still injured, disoriented, or emotionally overwhelmed. A defense lawyer’s early role is not to interfere with emergency work. It is to protect the driver from making uninformed statements, identify evidence that may disappear, and ensure that the government’s initial account is not treated as the only possible explanation.

Important evidence for your defense against vehicular homicide charges may include:

Crash Scene Measurements and Reconstruction

Investigators may use tire marks, debris fields, vehicle damage, roadway geometry, sight distances, and computer modeling to estimate speed and vehicle movement. A defense expert can evaluate whether those calculations depend on unsupported assumptions or incomplete measurements.

Vehicle Electronic Data

Event data recorders and other vehicle systems may contain information about speed, braking, acceleration, steering, restraint use, or system warnings. The meaning of that data depends on the vehicle, the recording interval, and whether the data was properly retrieved and interpreted.

Video and Photographs

Traffic cameras, doorbell cameras, businesses, transit vehicles, and other motorists may have recorded part of the incident. This evidence can disappear quickly, and may work in your favor by showing events that witnesses did not see clearly.

Witness Accounts

People observing a sudden crash may disagree about speed, traffic signals, lane position, or which vehicle moved first. Their vantage point, opportunity to observe, prior statements, and exposure to other accounts all matter.

Toxicology Evidence

In DUI cases, counsel may examine the legal basis for obtaining a blood sample, the timing of collection, chain of custody, laboratory procedures, measurement uncertainty, and whether the result supports the prosecution’s theory.

Phone and Digital Evidence

Police may investigate whether a driver was calling, texting, viewing an application, or otherwise interacting with a device. Records showing activity do not always establish who was using the phone or whether that use caused the collision.

Vehicle Condition and Maintenance

Brake failure, tire defects, steering problems, warning lights, recent repairs, recalls, and post-crash damage may require examination before the vehicle is released, repaired, or destroyed.

The police departments in Philadelphia and the surrounding counties have their own investigative procedures. Knowing these local protocols and the agencies involved can make a practical difference, especially when our Philadelphia vehicular homicide defense lawyer is able to intervene early, challenge assumptions, and begin gathering evidence in your favor. Early representation is particularly important when physical evidence, surveillance footage, electronic data, or the vehicle itself may not remain available indefinitely.

Challenging the Government's Case: Strategies Our Philadelphia Vehicular Homicide Defense Lawyer Can Explore in Your Case

A meaningful defense does not begin with a generic claim that the collision was “just an accident.” It begins by identifying precisely what the prosecution says that you, as the driver, did, what evidence supports that theory, and whether the alleged conduct legally and factually caused the death.

Depending on the case, your Philadelphia vehicular homicide defense lawyer may:

• Challenge causation: A traffic violation can occur without being the legal cause of a death. Your attorney may investigate another motorist’s actions, pedestrian conduct, roadway design, weather, visibility, mechanical failure, emergency medical complications, or other contributing causes.
• Distinguish recklessness from ordinary negligence: Section 3732 requires recklessness or gross negligence. Your defense attorney may argue that an error in judgment, momentary inattention, or failure to perceive a danger does not rise to the criminal standard alleged.
• Test the underlying violation: The Commonwealth must prove the relevant traffic law or DUI violation. Speed estimates, signal timing, lane-position evidence, chemical testing, and officer observations can all be disputed.
• Retain appropriate experts: Accident reconstruction engineers, toxicologists, medical experts, digital forensics specialists, or vehicle system experts may be needed to evaluate the government’s conclusions.
• Challenge unlawfully obtained evidence: Your lawyer can examine the legal basis for searches of the vehicle or phone, seizure of electronic data, custodial questioning, and compelled blood testing. Whether suppression is available depends on the facts and governing law.
• Prepare for the preliminary hearing and trial: The defense must determine which factual and legal issues should be developed early, which witnesses should be challenged, and whether the Commonwealth has sufficient evidence to continue prosecuting each charge.
• Evaluate negotiated outcomes without assuming one is available: Where the evidence cannot be fully defeated, we may assess whether the grading, individual counts, accompanying charges, or sentencing exposure can be reduced. Any possible resolution depends on the evidence, the prosecutor, the court, and the circumstances of the death.
• Develop mitigation: When sentencing exposure remains, your attorney may present the client’s history, medical circumstances, conduct after the collision, treatment, acceptance of responsibility where appropriate, and other information relevant to sentencing.

We recognize how sensitive these cases are, but a tragedy doesn’t erase your protections under the law or the burden that lies on the prosecution. Our goal as your Philadelphia vehicular homicide defense lawyer is to ensure that the emotional weight of a fatal crash does not replace the legal requirement that the Commonwealth prove every element beyond a reasonable doubt.

Prison Exposure, License Suspension, and Other Consequences in Vehicular Homicide Cases

When you’re facing charges of vehicular homicide, the immediate concern is substantial incarceration.

A non-DUI homicide by vehicle conviction under § 3732 is generally a third-degree felony punishable by up to seven years in prison. A homicide by vehicle while DUI conviction under § 3735 generally begins as a second-degree felony and carries a mandatory minimum of three years for each death, with increased grading and minimum sentences possible in specified circumstances.

A conviction under either statute also results in a three-year suspension of the person’s Pennsylvania operating privilege.

Other consequences may include:

• A felony record affecting employment and professional opportunities
• Loss of commercial driving eligibility or driving-dependent employment
• Restitution ordered as part of the criminal sentence
• Professional license reporting or disciplinary proceedings
• Immigration consequences for some noncitizens, depending on the offense and individual status
• Increased insurance costs or loss of available coverage
• A related wrongful death or personal injury claim

The criminal and civil cases require careful coordination. Statements, testimony, expert conclusions, and documentary evidence developed in one proceeding may affect strategy in the other. Your vehicular homicide attorney in Philadelphia, PA, should consider the broader litigation picture and how it could affect the criminal case before you give a recorded account or provide documents voluntarily.

Vehicular Homicide Cases in Philadelphia and the Surrounding Counties

Vehicular homicide charges are felony matters prosecuted in the court of common pleas. A Philadelphia case may proceed from arrest and preliminary arraignment through a preliminary hearing, formal arraignment, pretrial motions, plea negotiations, and trial in the Philadelphia Court of Common Pleas.

Cases arising in Montgomery, Delaware, Bucks, and Chester counties proceed through their respective magisterial district courts and courts of common pleas. Although the governing Pennsylvania statutes are the same, charging decisions, scheduling, plea practices, and courtroom procedures may differ by county.

The location of the crash can also affect the investigation. A collision on I-95, I-76, Roosevelt Boulevard, or another major roadway may involve Pennsylvania State Police, Philadelphia police, transportation agencies, roadway cameras, commercial vehicles, or multiple investigative units. Suburban cases may involve municipal police, county detectives, state police, or regional crash reconstruction teams.
