Vehicular manslaughter in Nevada

Vehicular manslaughter is generally described as an unintentional death caused by a vehicle, where the state alleges the defendant was the proximate cause and the death resulted from an act or omission that amounts to simple negligence.

Vehicular manslaughter under NRS 484B.657 requires only simple negligence, the ordinary failure to use reasonable care, that proximately causes a death. It is a misdemeanor. Most cases are fought on causation and fault. A tragic result does not automatically prove negligence.

Vehicular manslaughter does not require proof that the defendant intended to kill or intended harm. The focus is negligence, meaning whether the driving fell below what a reasonable driver would do, and whether that alleged negligence caused the death.

This is where the defense often works, because it can show the driving was reasonable under the circumstances, or that the alleged lapse did not cause the collision.

Many vehicular manslaughter cases are charged as misdemeanors when the state’s theory is simple negligence. Misdemeanor cases can still carry serious consequences, including custody exposure and license consequences.

If the allegation involves DUI or conduct the state frames as reckless, the case can be prosecuted more severely, and the defense strategy has to address those higher-stakes theories early.

Any ordinary driving task, performed negligently, can lead to a vehicular manslaughter allegation when a fatality occurs. Common scenarios include speeding, missing a stop sign, distraction inside the vehicle, and improper entry or exit from the roadway.

The defense usually focuses on reconstruction evidence and alternative causal explanations, including what other drivers did, what the roadway conditions were, and what the timing shows.

A strong defense is fact-driven. Common themes include third-party fault, mechanical failure, medical emergencies, and victim conduct, as well as challenges to the state’s causation theory.

These cases often require fast evidence preservation, including vehicle data, scene documentation, witness outreach, and any available video.

If you are facing a vehicular manslaughter allegation, do not discuss facts with anyone but your lawyer. Preserve your phone and any location data. If the vehicle has event data, keep it intact. If there is video from businesses or nearby homes, it should be requested quickly.

Early defense work is about controlling the record, challenging the state’s theory with objective evidence, and preventing a reconstruction narrative from hardening before the defense has a fair chance to test it.

A misdemeanor vehicular manslaughter conviction under NRS 484B.657 can be sealed after the waiting period, which for most misdemeanors is 1 year after release from custody or discharge from parole or probation. A death caused by DUI, charged under NRS 484C.430, can never be sealed. If you were convicted and believe legal errors occurred at trial, an appeal may be an option.
