A T-bone crash at a Phoenix intersection usually leaves one question first: who had the right of way? The answer drives everything that comes after, including the insurance company’s first move on your claim. This guide walks through how Arizona’s right-of-way statutes resolve fault in side-impact crashes, what evidence matters, what your injuries are worth tracking, and what to do in the first 72 hours. If you’re looking for a Phoenix t-bone intersection accident lawyer, the information below is what we tell clients in the first consultation.
A T-bone (or side-impact) crash happens when the front of one vehicle strikes the side of another, usually in an intersection. The vehicles form a rough “T” at the point of impact. Most of these crashes happen for one of four reasons:
Phoenix has specific intersection hot zones. ADOT crash data shows elevated rates at Bell Road, Northern Avenue, and Indian School Road interchanges off Loop 101. The Stack Interchange where I-10 meets I-17, and the Mini-Stack at I-10 and SR-202, see high-volume crashes including side-impacts at adjacent surface streets. The US-60 commuter corridor through Mesa sees heavy rush-hour intersection crashes as well. Our team handles cases across the Phoenix metro, including the suburbs where these corridors run.
Cars are engineered with crumple zones in the front and rear. The doors are not. There’s a few inches of metal and an airbag between the impact and the occupant’s torso, hips, and head. That’s why IIHS and NHTSA side-impact data show side crashes are deadlier per crash than either rear-end or front-end collisions at comparable speeds.
Compared to rear-end accidents in Phoenix (where whiplash and soft-tissue injuries dominate) and head-on collisions (where the engine block absorbs energy before it reaches occupants), T-bone crashes deliver force directly into the body. There’s no buffer. A 35 mph side-impact at an intersection can produce injuries you’d expect from a much higher-speed front collision.
Fault in a T-bone crash almost always turns on right-of-way. Arizona’s traffic code is specific about who has it and who has to yield.
The statutes that matter:
So the fault analysis in a typical Phoenix intersection crash looks like this:
The answers usually settle liability. Where they don’t, the case becomes an evidence fight.
The hardest T-bone cases are the ones where both drivers claim they had the green. Here’s what actually resolves them:
Adjusters in intersection cases frequently argue the injured driver “could have avoided” the crash by braking sooner or watching more carefully. That argument is easier to refute when you have camera footage, timing data, or EDR proof showing the other driver entered the intersection illegally. Without that evidence, the argument can stick and inflate your fault percentage.
Side-impact crashes produce injury patterns that differ from front or rear collisions:
Many of these injuries don’t show their full severity for 24 to 72 hours. Adrenaline masks symptoms. Internal bleeding develops slowly. If you didn’t go to the ER from the scene, go the same day or the next morning. Gaps in treatment are the first thing the adjuster will use to argue your injuries weren’t serious.
The first three days set up the rest of the claim.
At the scene (if you’re physically able):
– Call 911. A police report with an officer’s narrative carries weight with adjusters.
– Photograph everything: vehicle positions before they’re moved, debris field, traffic signals, skid marks, both vehicles’ damage, the intersection from multiple angles.
– Get the names and phone numbers of any witnesses. Don’t rely on the police report to capture them.
– Note the time. Signal phase timing is meaningless without it.
Within 24 hours:
– Get medical evaluation, even if you “feel fine.” Document everything.
– Notify your own insurance company. Don’t give a recorded statement to the other driver’s insurer yet.
– Request the police report number and start tracking down a copy. Here’s how to get a Phoenix car accident report.
Within 72 hours:
– Identify nearby businesses with cameras pointing at the intersection. Get a preservation letter out before footage is overwritten.
– Don’t post about the crash on social media. Anything you post becomes evidence the defense can use.
– Talk to an attorney before talking to the other driver’s adjuster.
On recorded statements: you are generally not required to give one to the other driver’s insurance company. Your duty to your own insurer depends on the cooperation terms in your policy, which an attorney should review before you say anything on the record.
Arizona is a pure comparative negligence state. Under Arizona’s pure comparative negligence rule (A.R.S. § 12-2505), your recovery is reduced by your percentage of fault, but you can still recover even if you’re mostly at fault. Even a driver who is 99% at fault can recover 1% of damages. That’s different from many other states, which bar recovery entirely once you cross 50% or 51% fault.
How this plays out in a T-bone case:
Say your damages total $100,000. The other driver ran a red light. The adjuster argues you entered the intersection on a stale yellow and should have anticipated the cross traffic. The claims file lands at 20% fault on you. Under comparative negligence in Arizona, your recovery becomes $80,000.
This is exactly why adjusters push hard on fault percentages in intersection cases. Every 10% they assign to you is 10% off the check they write. The evidence categories above (cameras, EDR, timing data, witnesses) are what push the fault percentage back toward zero.
T-bone crashes are catastrophic-injury crashes more often than rear-ends are. The insurance side of the case matters more.
Arizona minimum liability limits. Under A.R.S. § 28-4009, for policies issued or renewed beginning July 1, 2020, the state minimums are 25/50/15. That’s $25,000 bodily injury per person, $50,000 per accident, and $15,000 property damage. A serious T-bone with a hospitalization, surgery, and lost wages can blow through $25,000 in the first week. State minimums are often inadequate for these crashes.
Uninsured and underinsured motorist coverage. Under A.R.S. § 20-259.01, Arizona insurers must offer UM and UIM coverage. When the at-fault driver carries only state minimums and your damages are six figures, UIM on your own policy is often the only source of full recovery. We see this in T-bone cases constantly. If you’re not sure what UM/UIM you have, pull your declarations page and look. More on uninsured and underinsured driver claims in Arizona.
Government vehicles or malfunctioning signals. If a city bus, a government vehicle, or a malfunctioning traffic signal contributed to the crash, the deadline tightens dramatically. Under A.R.S. § 12-821.01, you must file a notice of claim with the government entity within 180 days of the incident, not the standard two years. Miss it, and the claim is gone. This matters in Phoenix because the city, ADOT, and various transit operators are routinely involved when signals fail or municipal drivers cause crashes.
Under A.R.S. § 12-542, you have two years from the date of the crash to file a personal injury lawsuit in Arizona. Property damage claims fall under the same two-year window.
The exception, again, is government entities. The 180-day notice-of-claim deadline under A.R.S. § 12-821.01 runs much faster than the two-year SOL and applies any time a public entity or public employee is potentially at fault.
For more detail on deadlines and how they interact, see Arizona’s statute of limitations guide.
Arizona allows punitive damages when the defendant acted with an “evil mind”, meaning conscious disregard for substantial risk of harm to others. The standard comes from cases like Linthicum v. Nationwide Life Ins. Co.
Intersection crashes can support punitives when:
Punitives are not awarded in every case. But where the facts support them, they often double or triple the available recovery.
We don’t publish settlement ranges, because every case is different and bar rules prohibit results-as-promises. What we can tell you are the factors that actually drive value in a T-bone case:
When all of those line up, clear liability, serious documented injuries, adequate insurance, T-bone cases tend to be among the highest-value crash claims we handle. When liability is disputed and insurance is thin, the case becomes a fight over every percentage point and every dollar of coverage.
Fault almost always turns on right-of-way. The driver who ran the red light, rolled the stop sign, or failed to yield on a left turn is typically at fault under A.R.S. §§ 28-771, 28-772, and 28-855. When both drivers claim they had the green, camera footage, signal timing data, and EDR downloads usually resolve it.
Yes. Arizona is a pure comparative negligence state under A.R.S. § 12-2505. Your recovery is reduced by your fault percentage, but you can recover even if you were mostly at fault. A 20% fault assignment on a $100,000 case yields $80,000.
Two years from the crash date under A.R.S. § 12-542. If a government vehicle or malfunctioning city traffic signal was involved, you must file a notice of claim within 180 days under A.R.S. § 12-821.01. Miss that, and the claim against the government is gone.
Generally no. The other driver’s insurance company is not your insurer, and you have no contractual duty to them. Duties to your own insurer depend on the cooperation terms in your policy. Talk to an attorney before giving any recorded statement.
This is common in T-bone crashes because the injuries are severe and Arizona minimums (25/50/15) are low. Your own uninsured/underinsured motorist coverage is often the only path to full recovery. Insurers are required to offer UM/UIM under A.R.S. § 20-259.01.
Most businesses overwrite security footage within 7 to 30 days. A written preservation letter sent within the first week of the crash is often what saves the evidence. Waiting a month usually means the footage is gone.
