California Penal Code 245: Assault With a Deadly Weapon

California Penal Code 245 is the state’s assault with a deadly weapon statute. It also covers assaults carried out with a level of force likely to cause great bodily injury, even when no weapon is involved. Most charges under the section are “wobblers” that prosecutors can file as either a misdemeanor or a felony, with sentences ranging from up to a year in county jail to as much as twelve years in state prison depending on the weapon used and who the victim was. A felony conviction counts as a strike under California’s Three Strikes law and triggers a lifetime firearm ban.

What the Prosecution Has to Prove

California defines assault as an unlawful attempt, coupled with the present ability, to commit a violent injury on another person.¹ For a charge under PC 245, the prosecution must establish four elements:²

You did something with a deadly weapon, firearm, or level of force that would naturally and probably result in physical contact with another person.
You acted willfully, meaning on purpose rather than by accident. The prosecution does not have to show you intended to hurt anyone or break the law.
You knew facts that would lead a reasonable person to realize the act would likely result in force being applied to someone.
At the moment you acted, you were physically capable of carrying out the harmful contact.

That last element matters more than people expect. Swing a bat at someone from across a large room with no way of reaching them, and the present ability is missing. The threat has to be real and immediate, not theoretical.

Actual contact, by contrast, is never required. Assault is complete the moment you take the action with the ability to follow through, whether or not you hit anyone. That is the line between assault and battery. Battery under Penal Code 242 requires that physical contact actually occurred; PC 245 criminalizes the dangerous attempt itself.

What Counts as a Deadly Weapon

Deadly weapons fall into two categories. The first is objects designed to cause death or serious injury: firearms, switchblades, brass knuckles, and the like. These qualify by their nature regardless of how they were used in a particular incident.

The second category is where most of the litigation happens. Any object can become a deadly weapon if it is used in a way capable of causing death or serious injury. Courts have found glass bottles, screwdrivers, heavy tools, and even pillows (used to smother someone) to qualify. The question is not what the object was designed for but how it was actually wielded.

Cars are among the most commonly charged “improvised” deadly weapons under PC 245.³ Courts look at the specific circumstances: how fast you were going, whether you steered toward someone, and whether the context (road rage, a parking lot confrontation, fleeing police) suggests you understood the vehicle could injure someone.

Force Likely to Produce Great Bodily Injury

Penal Code 245(a)(4) covers assaults that do not involve a weapon at all but use a level of force capable of causing serious harm.³ “Great bodily injury” means a significant or substantial physical injury, which is a higher bar than a bruise or a scratch. Broken bones, fractures, gunshot wounds, and serious concussions all qualify.

This charge typically applies to stomping on someone who is on the ground, strangling or choking, or delivering heavy blows with closed fists. Choking is a particularly common basis because it carries an obvious risk of death or brain damage even when it leaves no visible marks.

You can be convicted under 245(a)(4) even if the victim walked away without a scratch. The statute punishes the level of force you used, not the outcome. If the force was capable of causing significant injury, the charge stands regardless.

Penalties by Weapon Type

PC 245 has distinct penalty tiers depending on the weapon involved. The more dangerous the weapon, the harsher the sentence and the less discretion prosecutors have to reduce the charge.

Deadly Weapon (Not a Firearm) or Force Likely to Cause Great Bodily Injury

Charges under 245(a)(1) and 245(a)(4) are wobblers. As a misdemeanor, the maximum is one year in county jail and a fine of up to $10,000. As a felony, the sentence is two, three, or four years in state prison, with the same $10,000 maximum fine.³ Prosecutors decide the filing based on the severity of the conduct, your criminal history, and your age.

Firearm

Assault with a standard firearm under 245(a)(2) is also a wobbler, but the misdemeanor version carries a mandatory minimum of six months in county jail, with a maximum of one year. The felony version carries two, three, or four years in state prison and a fine of up to $10,000.³

Semiautomatic Firearm

Assault with a semiautomatic firearm under 245(b) is a straight felony with no misdemeanor option. The sentence is three, six, or nine years in state prison.³

Machine Gun, Assault Weapon, or .50 BMG Rifle

Under 245(a)(3), assault with a machine gun, assault weapon, or .50 BMG rifle is a straight felony carrying four, eight, or twelve years in state prison.³

Peace Officers and Firefighters

PC 245(c) and 245(d) impose steeper sentences when the victim is a peace officer or firefighter performing official duties. Every charge in this category is a straight felony, and the prosecution must prove you knew, or reasonably should have known, the victim was a protected official.

Deadly weapon or dangerous force without a firearm: three, four, or five years under 245(c).³
Firearm: four, six, or eight years under 245(d)(1).
Semiautomatic firearm: five, seven, or nine years under 245(d)(2).
Machine gun, assault weapon, or .50 BMG rifle: six, nine, or twelve years under 245(d)(3).

The knowledge requirement is a real defense point. If you genuinely had no way to know the person was a police officer (plainclothes, no badge, no announcement), the enhanced penalty may not apply. Courts set a low bar for “reasonably should have known,” though, so this defense rarely succeeds when the officer was in uniform or had identified themselves.

Consequences Beyond the Sentence

The jail or prison term is often not the worst part of a PC 245 conviction. Several collateral consequences attach automatically and can last for life.

A Strike on Your Record

Any felony conviction under PC 245 qualifies as a “serious felony” under Penal Code 1192.7(c)(31), which explicitly lists assault in violation of Section 245.⁴ That makes it a strike under California’s Three Strikes law. A second strike doubles the prison sentence for any future felony conviction. A third strike can result in 25 years to life, though California reformed the law in 2012 so that the third offense generally must also be a serious or violent felony to trigger the full term.⁵ Exceptions exist when the current offense involves a firearm, causes great bodily injury, or falls within certain other categories.

Firearm Ban

A felony conviction under PC 245 triggers a lifetime prohibition on owning or possessing any firearm. Penal Code 29800 makes it a separate felony for anyone convicted of a felony to own, purchase, receive, or possess a firearm.⁶ Federal law imposes a parallel ban under 18 U.S.C. § 922(g) on anyone convicted of a crime punishable by more than one year of imprisonment.⁷ Because every felony version of PC 245 carries a potential prison sentence exceeding one year, the federal ban applies automatically. A misdemeanor conviction under PC 245 can still result in a 10-year California firearm restriction, and if the assault involved a domestic relationship, federal domestic violence prohibitions may apply as well.

Immigration

For non-citizens, a PC 245 conviction can be devastating. Federal immigration law classifies a “crime of violence” with a sentence of at least one year as an aggravated felony.⁸ A felony assault with a deadly weapon conviction carrying a multi-year sentence typically meets that definition. An aggravated felony conviction makes a non-citizen deportable, bars eligibility for asylum and most other relief from removal, and can result in mandatory detention during removal proceedings with no option for bond. If you are not a citizen, talk to an immigration attorney before accepting any plea deal, because the immigration consequences often outweigh the criminal sentence itself.

Victim Restitution

California law requires courts to order full restitution to victims who suffered economic losses. Under Penal Code 1202.4, the court must order enough restitution to fully reimburse the victim for medical bills, mental health counseling, lost wages (including commission income), property damage, relocation costs, and security improvements.⁹ Restitution accrues interest at 10 percent per year from the date of sentencing. There is no statutory cap, and in cases involving hospitalization the amount can easily reach tens of thousands of dollars on top of any jail or prison sentence.

Common Defenses

Which defenses apply depends entirely on the facts, but a few come up repeatedly.

Self-Defense or Defense of Others

California law permits you to use reasonable force to protect yourself or someone else from imminent harm. You need to show three things: a reasonable belief that you or another person faced an immediate threat of bodily injury, a reasonable belief that force was necessary to stop that threat, and that you used no more force than a reasonable person would have considered necessary. The belief does not have to be correct, only reasonable given what you knew at the time. Future threats do not count, no matter how serious.

Lack of Present Ability

If you could not actually carry out the threatened harm at the moment of the alleged assault, a key element is missing. Courts are split on whether pointing an unloaded gun at someone who does not know it is unloaded qualifies, but a verbal threat made over the phone clearly lacks present ability. The defense works best when there was a physical barrier or distance that made contact impossible.

No Willful Act

Accidents are not assault. If you dropped a heavy object that narrowly missed someone, or your car slid on ice toward a pedestrian, the prosecution cannot establish willfulness. The act itself must be intentional, even though you do not need to have specifically intended to hurt anyone.

Expungement After Probation

California allows defendants who successfully complete probation to petition the court for relief under Penal Code 1203.4. If granted, the court permits you to withdraw your guilty or no-contest plea, enters a not-guilty plea, and dismisses the case.¹⁰ This relief is available for both misdemeanor and felony PC 245 convictions, provided you have finished probation and are not currently serving a sentence or facing new charges. An unpaid restitution order cannot be used as grounds to deny the petition, and the prosecution must receive at least 15 days’ notice before the court rules.

Expungement under 1203.4 has real limits. It does not restore firearm rights, does not remove a strike for Three Strikes purposes, and may not eliminate immigration consequences. Many professional licensing boards still require you to disclose the original conviction even after dismissal. The relief helps most with private-sector employment, where California law restricts employers from asking about dismissed convictions on job applications.
