12 News reported that a Phoenix police officer was taken to a hospital after a traffic collision Thursday afternoon near 19th Avenue and Thunderbird Road. No determination of fault has been reported, and nothing beyond those facts is known publicly at this point.
When a crash in Arizona involves an on-duty police officer or any other government employee, the claim follows a different set of rules than an ordinary collision between two private drivers. A person injured by a public employee acting within the scope of employment generally has to serve a written notice of claim on the employee and on the public entity that employs them within 180 days of the event, under A.R.S. § 12-821.01; the notice has to state the facts, the amount the claimant will accept to settle, and the basis for that figure. Miss that window and the claim is barred no matter how strong the underlying facts are. Claims against public entities and their employees also carry a one-year filing deadline, shorter than the two-year personal injury deadline in A.R.S. § 12-542 that applies to private defendants. Fault is still decided under Arizona's pure comparative fault rule in A.R.S. § 12-2505, which reduces recovery by each party's own share of responsibility.
The 180-Day Notice Is the Deadline Most People Miss
A.R.S. § 12-821.01 is not a formality. The notice of claim must go to the public entity and to the individual employee, must be served the way Arizona court rules require for service on that entity, and must contain a specific settlement demand with the facts supporting it. A vague letter saying you intend to sue does not satisfy the statute. Courts have dismissed otherwise valid claims because the demand figure was missing or because the notice reached the entity's insurer but not the entity itself.
One hundred eighty days passes faster than it sounds when you are treating for injuries. If a government vehicle or a government employee may have been involved in your collision, treat the notice deadline as the first thing on your list, not the last. Note also that the private-party two-year deadline under A.R.S. § 12-542 may still apply to other drivers in the same crash, so a single collision can carry two different clocks.
Being On Duty Does Not Decide Fault
Emergency vehicles have limited statutory privileges in Arizona when responding with lights and siren, but those privileges are not unlimited and do not relieve a driver of the duty to drive with regard for the safety of others. Whether a patrol vehicle was running as an emergency vehicle at the time, and whether that mattered to how the collision happened, is a factual question answered by the crash report, scene evidence, and any available video.
Arizona uses pure comparative fault under A.R.S. § 12-2505. Even a driver assigned a large share of responsibility can recover something, reduced by that share. That rule cuts both ways, which is why early statements to an insurance adjuster matter. Under A.R.S. § 28-661, any driver involved in a collision causing injury has a duty to stop and remain at the scene, and that obligation applies regardless of who the other driver is.
Practical Steps After a Collision Involving a Government Vehicle
Get the crash report number before you leave the scene, and request the full report once it is available. Photograph vehicle positions, debris, signal phases, and the intersection layout if you are physically able. Write down what you remember the same day; memory for sequence and timing degrades quickly.
Get evaluated medically even if you feel functional. Gaps between a collision and the first treatment note are the most common argument insurers use to discount injury claims. Ask whether any nearby businesses or traffic cameras captured the intersection, because that footage is often overwritten within days or weeks. Do not give a recorded statement to any insurer before you understand what deadlines apply to your claim; with a public entity involved, the clock under A.R.S. § 12-821.01 is already running.
