You were riding through an intersection on Camelback, Bell, Indian School, or some other Phoenix arterial. A driver coming the other way turned left across your lane. You went over the bars, or down on your side, or straight into the quarter panel. Now you’re hurt, the driver is telling the police “I didn’t see the motorcycle,” and the insurance adjuster is already hinting that you were going too fast.
This article walks through who’s actually at fault in a left-turn motorcycle accident in Phoenix, how Arizona law calculates recovery when the adjuster tries to shift blame onto the rider, what these claims tend to be worth, and what to do next.

The fact pattern is almost always the same. The motorcycle is traveling straight through an intersection with a green light or the right-of-way. A car or SUV coming from the opposite direction makes a left turn across the rider’s path. The rider either lays the bike down trying to avoid the collision, T-bones the side of the turning vehicle, or gets clipped and thrown over the hood.
These crashes happen most often at signalized intersections with permitted left turns (no dedicated green arrow), in the late afternoon when sun glare is bad, and in left-turn lanes on roads like 7th Street, Thomas, Bell, and Cave Creek. We see this pattern over and over in Phoenix.
The reason it matters: motorcyclists are roughly 28 times more likely than car occupants to die in a crash per vehicle mile traveled, according to NHTSA. The difference between a fender bender for the driver and a hospital stay for the rider is the entire point of why these claims are serious from the first hour.
Arizona law is direct on this. Under A.R.S. § 28-772, a driver intending to turn left at an intersection must yield the right-of-way to any vehicle approaching from the opposite direction that is within the intersection or so close as to constitute an immediate hazard.
That last part does the heavy lifting. A motorcycle approaching the intersection at a legal speed with the green light is exactly the kind of “immediate hazard” the statute is talking about. When a left-turning driver moves through that gap and hits a rider, they violated their statutory duty to yield. That’s not a judgment call. It’s written into the traffic code.
In practice, this means the left-turning driver is presumed at fault in the overwhelming majority of these collisions. Police reports usually reflect that. So do insurance liability findings, at least initially. The exceptions are narrow: the rider ran the red, the rider was traveling at a wildly excessive speed, or the rider appeared from a hidden position right before the turn started. Otherwise, the duty to yield rests with the car.
Almost every left-turning driver says some version of this to the responding officer. “I looked, but I didn’t see him.” “He came out of nowhere.” “The sun was in my eyes.”
Here’s what the law says about that: not seeing what should have been seen is not a defense to a duty-to-yield violation. The statute requires the turning driver to verify the lane is clear before crossing it. “I didn’t see” is the same as “I didn’t look carefully enough.” That’s negligence, not an excuse.
Insurance adjusters know this. They don’t argue the legal point. Instead, they pivot to a different argument: that even if their driver was wrong, the rider was partly wrong too. That’s where comparative negligence comes in.
Arizona is a pure comparative negligence state under A.R.S. § 12-2505. It’s one of only 12 states with this rule. Pure comparative negligence means a rider’s recovery is reduced by the rider’s percentage of fault, but recovery is still possible even if the rider was mostly at fault. The math works the same way at 1% fault or 99% fault: damages times (100% minus rider fault percentage) equals recovery. The deeper breakdown lives on our page about Arizona’s pure comparative negligence rule.
Here’s a worked example using a left-turn motorcycle scenario.
Say total damages come to $100,000: medical bills, lost wages, future care, and pain and suffering. The driver turned left across the rider’s lane. The rider was doing 5 mph over the posted limit. The adjuster argues the rider’s speed contributed to the crash. A jury (or settlement negotiation) assigns the rider 30% of the fault.
Recovery: $100,000 minus 30% equals $70,000.
That number can shift dramatically based on how the fault percentage gets argued. A jump from 30% rider fault to 50% rider fault costs the rider $20,000 on a $100,000 claim. On a $500,000 catastrophic-injury claim, the same shift costs $100,000. This is why the adjuster’s strategy is almost always the same: inflate the rider’s fault percentage, reduce the payout.
Arizona’s helmet law, A.R.S. § 28-964, requires helmets only for riders and passengers under 18. Adults can legally ride without one.
Legal does not mean the adjuster won’t try to use it. We see this constantly. A rider in their 30s suffers a head injury in a left-turn crash. They weren’t wearing a helmet. They had no legal obligation to wear one. The adjuster still argues that the rider’s failure to wear a helmet contributed to the severity of the head injury, and tries to assign comparative fault on that basis.
There are counterarguments. Sometimes a helmet would not have prevented the specific injury. Sometimes the impact forces exceeded helmet protection ratings. Sometimes the injuries are to areas a helmet doesn’t cover. Whether helmet non-use can be raised as comparative fault at all in Arizona is fact-specific and contested, and the answer depends on the injury, the expert testimony, and how the claim is framed. The point is: a rider without a helmet who got hurt should expect this argument and shouldn’t accept it at face value from an adjuster.
If lane position is also being raised against a rider (filtering between stopped cars, riding in the wrong part of the lane), that’s a separate fight. Lane filtering became legal in Arizona under specific conditions in 2022; full lane splitting between moving vehicles is still illegal. Adjusters routinely conflate the two.
The adjuster handling the left-turn driver’s claim has a specific playbook. We’ve seen it in close to every motorcycle matter we handle:
The counter to all of these is documentation. Crash reconstruction, witness statements, traffic camera footage if it exists, the driver’s own admissions to the responding officer, and medical evidence linking injuries to the impact. The earlier we get involved, the more of this evidence can be preserved.
The injury patterns in these crashes are predictable because the physics are predictable. Common motorcycle injuries from left-turn collisions include:
These are the injuries that drive claim value, and they’re the injuries adjusters most aggressively try to minimize. For brain injury claims specifically, we cover what makes those different on our Phoenix brain injury page.
Arizona law allows three categories of damages in a left-turn motorcycle claim.
Economic damages are the quantifiable losses. Medical bills (past and future), lost wages, lost earning capacity, property damage to the bike and gear, and out-of-pocket costs. These are the numbers documented with invoices, pay stubs, and expert reports on future care.
Non-economic damages cover pain, suffering, disfigurement, loss of enjoyment of life, and emotional distress. Critically, Arizona has no cap on non-economic damages. Article 2, Section 31 of the Arizona Constitution explicitly prohibits the legislature from limiting recovery for damages in personal injury actions. That matters in catastrophic motorcycle claims where the non-economic component can dwarf the economic component. More on non-economic damages in Arizona.
Punitive damages are available in narrower circumstances: DUI, road rage, intentional misconduct, or gross negligence. If the driver who turned across the rider’s lane was drunk, on their phone in a way that rises beyond ordinary distraction, or otherwise behaving with conscious disregard for safety, punitive damages can come into play.
Arizona’s minimum liability insurance under A.R.S. § 28-4135 is 25/50/15: $25,000 bodily injury per person, $50,000 per accident, $15,000 property damage. A meaningful number of drivers in Phoenix carry exactly this minimum.
For a motorcycle rider with a serious injury, $25,000 is nothing. A single hospital stay with surgery routinely exceeds $100,000 in billed charges. Add future treatment, lost wages, and pain and suffering, and the at-fault driver’s policy gets blown through immediately.
This is where uninsured and underinsured motorist coverage (UM/UIM) on the rider’s own policy becomes the claim. Under A.R.S. § 20-259.01, insurers must offer UM/UIM coverage in Arizona, but consumers can reject it in writing. If a rider accepted it (which they should have), it’s available when the at-fault driver’s policy is insufficient. UM/UIM minimums in Arizona match liability minimums (25/50), and Arizona prohibits stacking UM coverage across multiple policies, so the coverage amount purchased is the amount available, period.
Two practical points:
A rider has 2 years from the date of the accident to file a personal injury lawsuit in Arizona under A.R.S. § 12-542. Miss it and the claim is gone, no matter how strong the underlying facts were. There are a few narrow exceptions (minors, certain government claims with shorter notice windows), but the default is 2 years and any plan should be built around that. More on Arizona’s statute of limitations.
Evidence moves faster than the deadline does. Traffic camera footage at most Phoenix intersections gets overwritten in 30 to 90 days. Witness memories degrade in weeks. The turning vehicle gets repaired and crash evidence disappears. Skid marks fade. The longer a rider waits to get an attorney involved, the more of the underlying record has already evaporated by the time anyone goes looking for it.
If the crash just happened, in roughly this order:
Police reports are not the final word on liability. They reflect the officer’s on-scene impression, often based on incomplete information. We’ve handled left-turn motorcycle matters where the initial police report blamed the rider and the final liability finding put the turning driver at 80% or 100% fault after the full evidence came out. The report is not the end of the analysis.
In most situations, yes. Arizona’s helmet law only requires helmets for riders under 18. Adults riding without a helmet are not violating any law. Insurance adjusters may argue that helmet non-use contributed to the severity of head injuries, but whether that argument actually reduces recovery is fact-specific, often contested, and depends on the injury and expert testimony. The absence of a helmet does not automatically kill a claim.
It depends almost entirely on injuries, fault percentage, and available insurance coverage. A claim with soft tissue injuries and full liability coverage looks completely different from one involving a TBI, multiple surgeries, and a minimum-limits at-fault driver. Claims with serious orthopedic injuries and brain injuries often run well into six figures and sometimes far beyond, while claims with less severe injuries settle for much less. We give a real range after reviewing the file, not a billboard number.
This is where uninsured motorist coverage comes in. UM coverage on a rider’s own policy steps into the shoes of the at-fault driver’s nonexistent liability coverage. With UM, there’s a path to recovery. If UM was rejected in writing when the policy was purchased, the options narrow considerably, though there may still be assets to pursue or other policies that apply.
Most claims resolve in 6 to 18 months. Matters that require litigation can take longer. The biggest factor is how long it takes to reach maximum medical improvement, because settling before the full extent of the injuries is known is how riders get badly underpaid. Claims involving major injuries are worth waiting out.
Most claims settle without a trial. Filing a lawsuit is sometimes necessary to put real pressure on the insurance company, but even claims that get filed usually resolve through negotiation, mediation, or arbitration before reaching a jury.
The driver’s insurance company has already started building their file. They’ve talked to their driver. They’ve looked at the police report. They’re deciding right now how much to offer and how aggressively to fight the rider’s fault percentage.
