These are the questions most asked by people facing investigation or charges after a serious Arizona accident.
What should I do if I am being investigated for a vehicular crime in Arizona?
Do not speak to investigators or your insurance company without an attorney present. Exercise your right to remain silent immediately and completely.
Call Long & Simmons Law immediately. Early involvement helps preserve physical evidence, secure vehicle data records before they are overwritten, identify witnesses, and begin independent accident reconstruction.
Is a vehicle considered a dangerous instrument in Arizona?
Yes. Under ARS 13-105, Arizona defines a dangerous instrument as anything that, under the circumstances in which it is used, is readily capable of causing death or serious physical injury. A motor vehicle involved in a serious collision is routinely treated as a dangerous instrument.
This classification triggers mandatory prison sentencing provisions and can eliminate probation or suspended-sentence options.
What is the difference between vehicular manslaughter and second-degree murder in Arizona?
Manslaughter requires recklessness: conscious disregard of a known substantial risk. Second-degree murder requires knowing conduct or extreme recklessness creating a grave risk of death.
Manslaughter is a Class 2 felony. Second-degree murder is a Class 1 felony. The difference in mandatory sentencing can be measured in decades.
What role does negligent homicide play in a vehicular crime case?
Negligent homicide is rarely the initial charge in serious vehicular cases. It often becomes relevant as a lesser included offense or a plea reduction from manslaughter.
Securing a reduction to negligent homicide can dramatically reduce mandatory sentencing exposure.
Can a DUI charge become a vehicular homicide or murder charge in Arizona?
Yes. When a DUI results in death, prosecutors can charge vehicular manslaughter or second-degree murder. DUI supplies circumstantial evidence that the driver knew they were impaired and consciously disregarded a risk.
At extreme BAC levels, prosecutors may argue knowing conduct or grave risk to support second-degree murder.
Can the police accident reconstruction be wrong?
Yes. Police reconstructions depend on measurements, assumptions, and interpretations that can contain errors. Independent reconstruction can dispute speed, point of impact, fault assignment, and sequence of events.
A contested reconstruction can create reasonable doubt about the prosecution's factual theory.
If police did not charge me at the scene, can I still be charged later?
Yes. Blood test results, reconstruction analysis, witness interviews, and surveillance review can take weeks or months. Many serious vehicular charges are filed after the scene investigation is over.
If investigators contact you after a serious accident, treat that as the beginning of a criminal case and call us before responding.
What is a vehicle data recorder and how is it used?
Modern vehicles often contain event data recorders that capture speed, braking, throttle position, steering input, and seatbelt status in the seconds before a collision.
This data can confirm or contradict witness accounts and police reconstruction. It must be preserved quickly because it can be lost or overwritten.
Can a mechanical failure defense work in a vehicular crime case?
Yes, when supported by evidence. A sudden, unforeseeable brake failure, tire blowout, or steering malfunction can negate the criminal mental state required for conviction.
The defense requires vehicle inspection, maintenance records, and often expert testimony.
Does Arizona have a statute of limitations on vehicular manslaughter?
Arizona generally has a seven-year statute of limitations for most felonies, including manslaughter. Murder charges, including second-degree murder, have no statute of limitations.
In practice, vehicular crime charges are usually filed promptly after investigation, so early defense involvement matters.
