AB 11 redesigns part of California Penal Code §402 that governs people who go to emergency scenes to view or otherwise impede responders. The bill reframes how unmanned aerial vehicles (UAVs, remote piloted aircraft, drones) are treated when their operation interferes with emergency personnel, particularly during fire-related incidents.
The change shifts the policy emphasis from a misdemeanor deterrent aimed at on-the-ground spectators toward a stronger criminal response for aerial interference in fire incidents. That shift has operational and budgetary consequences for local law enforcement, fire agencies, and drone operators — and it imports evidentiary and jurisdictional questions about identifying and prosecuting remote operators.
At a Glance
What It Does
The bill amends Penal Code §402 to bring drone operators within the statute’s scope and to subject certain drone activity at fire scenes to an enhanced criminal classification. It preserves the existing misdemeanor rule for people who impede responders on the ground but singles out UAV conduct during fire-related emergencies for tougher treatment.
Who It Affects
This targets individual hobbyist pilots, commercial drone operators, and any remote operators whose aircraft appear at or over a fire scene. It also affects local prosecutors, county jails, fire and aviation coordinators who must document interference, and agencies that monitor and respond to airspace incursions.
Why It Matters
The bill raises legal risk for aerial observers at wildfires, signaling a stricter enforcement posture that could deter hazardous flights and reduce risks to firefighting aircraft. It also raises costs and enforcement burdens for local governments and creates interaction points with federal aviation rules and privacy concerns.

What This Bill Actually Does
AB 11 modifies Penal Code §402 by drawing the statute’s reach explicitly to unmanned aircraft and by elevating certain drone conduct at fire incidents. The statute already criminalizes people who go to or stop at emergency scenes to view and, in doing so, impede emergency personnel; the new language clarifies that an operator of an unmanned aerial vehicle qualifies as a “person” under the statute regardless of where the operator is physically located.
That change removes a possible loophole where remote operation might have been treated differently from on-the-ground presence.
Most consequentially, the bill adds a distinct provision that treats operating a drone in violation of the statute during a fire-related emergency as a higher-class offense. The operative elements for that enhanced offense remain tied to the core prohibition: the aircraft must be at the scene of the emergency and the operator’s conduct must run afoul of §402’s restrictions (for example, by impeding responders).
The bill directs that the enhanced offense be punished under the county-jail sentencing provision referenced in §1170(h) and authorizes a monetary fine; those references convert what has been a misdemeanor deterrent into a felony-level exposure with attendant collateral consequences.Other parts of §402 remain unchanged and continue to govern interfering with lifeguards and define what counts as an “emergency” (the list includes fire, explosion, airplane crash, flooding, windstorm, railroad or traffic accidents, industrial and toxic incidents, and other natural or human-caused events). Finally, the bill includes the standard Article XIII B reimbursement carve-out saying the state need not reimburse local governments for costs tied to creating or changing a crime.
Practically, that means counties bear the operational and fiscal impact of prosecutions, jail time, and any additional investigations required to link a remote operator to a specific flight that impeded response.
The Five Things You Need to Know
The bill inserts a new subdivision (a)(3) into Penal Code §402 that specifically criminalizes operating a UAV, remote piloted aircraft, or drone in violation of §402 during a fire-related emergency.
Subdivision (a)(2) already treats an unmanned aircraft operator as a “person” for §402 purposes regardless of the operator’s physical location, making remote pilots prosecutable under the statute.
The enhanced UAV offense is to be punished pursuant to Penal Code §1170(h), converting exposure to county-jail felony terms (16 months, or 2 or 3 years) and authorizes a fine not to exceed $10,000.
The statute maintains an exemption for people whose presence or observation is part of their employment duties, leaving professional incident-response contractors, official aerial observers, and authorized agencies outside its reach when acting lawfully.
Section 2 states that the act creates a new crime and therefore disclaims state reimbursement to local agencies under Article XIII B of the California Constitution, shifting cost implications to counties.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Core misdemeanor for on-scene viewers who impede responders
This subsection retains the existing prohibition: a person who goes to or stops at an emergency scene to view and thereby impedes emergency personnel is guilty of a misdemeanor unless the viewing is part of the person’s employment. Practically, this is the baseline conduct the legislature already criminalized to prevent ‘rubbernecking’ that obstructs response activity. It continues to be the predicate against which any UAV conduct will be measured.
Expands 'person' to include remote UAV operators
This clause clarifies that a person includes anyone who operates or uses an unmanned aerial vehicle at the scene of an emergency, irrespective of where the operator is located. That textual clarification is significant: it makes geographic separation between a pilot and a scene irrelevant for charging purposes and removes a potential defense that the operator was not physically present.
New felony for UAV operation during fire-related emergencies
The bill adds a standalone provision making operation of a drone in violation of the subdivision during a fire-related emergency a felony punishable under §1170(h) and subject to an additional fine up to $10,000. That shifts certain drone conduct from misdemeanor prosecution to felony exposure, with both sentencing and collateral-impact consequences (felony record, different custody and parole frameworks). The reference to §1170(h) signals county-jail terms rather than state-prison placement for qualifying felony offenses.
Lifeguard interference remains a misdemeanor
Subdivision (b) keeps the existing misdemeanor for knowingly resisting or interfering with a lifeguard performing emergency duties. The bill does not alter this provision’s standard elements or penalties; it remains focused on rescuers’ on-water operations where immediacy and physical interference are the primary concerns.
Broad statutory definition of 'emergency'
Subdivision (c) lists the categories that qualify as an emergency — from fires and explosions to transportation wrecks and toxic spills — and concludes with a residual clause for ‘any other natural or human-caused event.’ That breadth gives prosecutors latitude to apply the statute to many on-scene incidents, but it also raises scope questions when an incident’s character (for example, whether a fire is ‘fire-related’) is contested.
No state reimbursement for local costs
Section 2 invokes the usual Article XIII B carve-out: because the act creates or changes a crime, the state will not reimburse local agencies for costs arising from implementing the law. For counties this means any additional investigative work, prosecutions, and jail housing costs associated with charging and convicting the new felony are local obligations.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Firefighting aviation crews — reduced risk from unauthorized drones near incident airspace should lower collision and disruption risk for air tankers and helicopters, easing operational constraints.
- On-scene ground firefighters and emergency personnel — fewer aerial distractions and potential impediments may speed tactical operations and increase responder safety when the law deters reckless flights.
- Local prosecutors seeking deterrent options — the felony classification gives prosecutors a stronger charging option when interference is severe, and a clearer statutory basis for pursuing serious aerial misconduct.
Who Bears the Cost
- Hobbyist and commercial drone operators — the law raises criminal exposure (and potential fines) for flights near fire scenes, increasing compliance costs and legal risk for pilots who lack clear situational awareness.
- Counties and local criminal-justice systems — because the bill creates a new felony without state reimbursement, counties absorb additional investigation, prosecution, and jail costs tied to charging and adjudicating the offense.
- Emergency-response agencies and incident commanders — the onus to document interference, identify operators, and preserve chain-of-custody evidence falls to local responders, increasing administrative and operational burdens.
Key Issues
The Core Tension
The bill confronts a classic trade-off: protect firefighting operations and public safety by imposing tougher criminal penalties on aerial interference, or avoid expanding felony liability in ways that criminalize inadvertent or hard-to-prove remote conduct and strain local criminal-justice systems. The statute seeks deterrence, but effective and equitable enforcement will hinge on proving intent and attribution without producing disproportionate or inconsistent outcomes.
The bill’s practical impact depends heavily on evidentiary and attribution mechanics that the text does not resolve. Prosecutors must prove that a UAV was ‘at the scene’ of a fire-related emergency and that the operator’s conduct violated §402 — historically a statute aimed at on-the-ground spectators who impede responders.
Translating that intent- and causation-focused framework to remote aircraft raises questions: did the operator intend to view, did the flight actually impede response, and can investigators reliably tie a particular aircraft to a particular operator? Those are nontrivial burdens that could limit the number of viable felony prosecutions.
A second tension is federal-state interaction. The Federal Aviation Administration controls navigable airspace and regulates drone operations; it does not generally impose criminal penalties for flights that interfere with firefighting aircraft, but it can issue safety advisories or administrative sanctions.
This bill creates a parallel criminal regime at the state level, which is permissible but may require coordination when evidence collection involves flight-tracking data, transponder or telemetry disclosures, or cross-jurisdictional operators. Another unresolved area is whether the statute’s residual ‘any other natural or human-caused event’ language will invite vagueness challenges or divergent prosecutorial application across counties.
Finally, the shift to felony exposure balances deterrence against overcriminalization. Raising penalties may deter dangerous conduct, but it may also sweep in marginal or inadvertent violations by uninformed pilots, or create prosecutorial pressure to pursue cases that strain local resources.
The increased reliance on county-level enforcement, without state reimbursement, also risks uneven application: better-resourced counties may prosecute aggressively while others decline to pursue cases absent clear operational harm.
