When a DUI accident injures or kills someone and the driver leaves, the charge is no longer a minor traffic matter. It is felony hit-and-run under Vehicle Code 20001, one of the most serious driving offenses in California. I am Joel Brand, and here is what the statute requires and how these cases are defended.

The text of the law

Vehicle Code 20001. (a) The driver of a vehicle involved in an accident resulting in injury to a person, other than himself or herself, or in the death of a person shall immediately stop the vehicle at the scene of the accident and shall fulfill the requirements of Sections 20003 and 20004. (b)(1) Except as provided in paragraph (2), a person who violates subdivision (a) shall be punished by imprisonment in the state prison, or in a county jail for not more than one year, or by a fine of not less than one thousand dollars ($1,000) nor more than ten thousand dollars ($10,000), or by both that imprisonment and fine. (2) If the accident described in subdivision (a) results in death or permanent, serious injury, a person who violates subdivision (a) shall be punished by imprisonment in the state prison for two, three, or four years ... However, the court, in the interests of justice and for reasons stated in the record, may reduce or eliminate the minimum imprisonment required by this paragraph.

What the statute requires

Like its property-damage counterpart, Section 20001 is about a duty to stop, not about fault for the accident. After an accident that injured or killed another person, the driver must immediately stop at the scene and fulfill the duties in Sections 20003 and 20004: provide identifying information, render reasonable assistance, and report as required. The crime is the failure to do those things. Critically, it applies even if you did not cause the accident.

It is a wobbler with two tiers

Felony hit-and-run is a wobbler, meaning it can be charged as a felony or a misdemeanor. The base version under subdivision (b)(1) carries up to a year in jail or a state prison term. The aggravated version under (b)(2), where the accident caused death or permanent, serious injury, carries two, three, or four years in state prison, though the statute itself lets the court reduce or eliminate the minimum in the interests of justice. Where the case falls on this ladder is one of the most important things to fight over early.

The knowledge element is central

To be guilty, you must have known, or reasonably should have known from the nature of the accident, that someone was injured or that an injury was probable. This is often the strongest defense. In a chaotic crash, at night, or after a low-visibility impact, a driver may genuinely not have known a person was hurt. Without that knowledge, the duty to stop for an injury was not triggered, and the felony charge fails. I examine closely what the driver actually knew and when.

Why it pairs with a DUI

Hit-and-run frequently accompanies a DUI, because an impaired driver may flee in panic or fail to grasp what happened. When both are charged, the prosecution gains a powerful narrative and may argue that leaving showed consciousness of guilt about the drinking. But leaving a scene is not proof of impairment, and the two charges require separate proof. Keeping the hit-and-run from being used to inflate the DUI, and the DUI from inflating the hit-and-run, is part of the defense. See DUI involving a collision and how hit-and-run complicates a DUI.

Felony versus the misdemeanor version

The dividing line is injury. If the accident caused only property damage, the applicable statute is the misdemeanor Vehicle Code 20002. The moment there is injury or death to another person, 20001 applies and the exposure rises dramatically. Determining which statute the facts actually support, and whether any injury truly meets the "permanent, serious" threshold that triggers the harsher tier, is a key early question.

Common defenses

  • No knowledge of injury. You did not know and could not reasonably have known a person was hurt.
  • You did stop and fulfill the duties, or made reasonable efforts to.
  • You were not the driver, or identity is not established.
  • The injury does not meet the aggravated threshold, reducing the exposure.
  • Civil restitution and mitigation can support a reduction to the misdemeanor or a lighter resolution.

How I defend it

I attack the knowledge element first, then whether the duties were actually met, the identity of the driver, and the severity tier, all while defending the underlying DUI through the stop, the testing, and the chemistry. Because the court retains discretion over the minimum term, strong mitigation and prompt restitution genuinely matter. See my top DUI defenses and the penalties guide.

The duty applies even if the accident was not your fault

This surprises people, so it is worth emphasizing. Section 20001 punishes leaving, not causing. Even if the other driver ran the light, even if you were not at fault at all, the law still required you to stop and exchange information and render aid. That means a person can be entirely blameless for the collision itself and still face a felony for driving away. The flip side is that the prosecution's case is about the leaving and the knowledge of injury, not about who caused the crash, which focuses the defense on those specific elements rather than on a fault contest that may not matter to this charge.

Why restitution and early action help

Because the court keeps discretion over the minimum prison term in the aggravated tier, what happens early can change the sentence. Promptly arranging restitution for the victim, demonstrating that any failure to stop came from genuine lack of knowledge rather than indifference, and presenting strong mitigation all give the court and the prosecutor room to treat the case less harshly. In the right circumstances these efforts support a reduction to the misdemeanor or a resolution that avoids state prison, which is why I begin that work immediately rather than waiting for the case to harden.
