Who is at fault when a car turns left in front of a motorcycle in Phoenix?

Of all the ways a driver can injure a motorcyclist, the left turn is the most common. The latest NHTSA data shows that in 46% of fatal crashes between a motorcycle and another vehicle, the car was turning left while the rider went straight. The physics are brutal. A motorcyclist has no hood and no airbags, so the body absorbs the hit against the side of the turning car.

Legally, fault almost always lands on the driver who turned. The insurance company starts from the opposite end, working to shift the blame onto the rider. What you actually recover comes down to two things: the Arizona left turn statute and the state's pure comparative negligence rule. Kermani LLP handles these cases, and here's how they really work.

Understanding the Arizona left turn law

The rule is simple and old. A driver turning left at an intersection has to yield to oncoming traffic that is either already in the intersection or close enough to create an immediate danger. A.R.S. § 28-772 calls that an immediate hazard, and the whole fight tends to circle back to those two words.

The statute doesn't single out motorcycles. To the law, a bike is oncoming traffic like any car. The catch is that an immediate hazard isn't a fixed distance in feet. It's a threshold of perception and reaction time, and that's where the defense goes to work.

One detail gets missed a lot. A solid green light and a green arrow are not the same thing. On the arrow, the turn is protected and nobody has to yield. On a solid green, you can turn, but only after letting oncoming traffic clear. Almost every left-turn crash involving a motorcycle happens on that solid green when a driver decides he can beat the bike through. Along busy multi-lane roads like Camelback Road and McDowell Road, where left turns stack up cycle after cycle, the setup repeats all day.

In a left turn accident who is at fault?

In a left turn accident, the driver who turned is almost always at fault. The motorcyclist going straight has the right-of-way, and the driver crossing that path takes it away. Police reports usually log the crash as a failure to yield. The presumption of fault sits with the turning car.

A presumption isn't an automatic win. The insurer will argue that the rider was speeding and appeared so suddenly that he became the very immediate hazard the driver couldn't judge in time. What settles that argument isn't testimony. It's evidence: the police report, footage from traffic and private cameras and measurements taken at the scene.

Arizona gives you two years to file (A.R.S. § 12-542), and the Arizona personal injury statute of limitations is worth keeping in mind from day one. But the proof that establishes failure to yield starts vanishing long before that. Cameras record over themselves, skid marks fade, witnesses forget faces and details. The first few weeks after a crash matter more than the last month before the deadline.

How comparative negligence impacts Phoenix motorcycle crashes

Even if part of the fault is yours, you still recover. Arizona runs on pure comparative negligence: A.R.S. § 12-2505 says plainly that a claimant's action isn't barred, and the award drops in proportion to the claimant's share of fault. Put a rider 10% at fault for mild speeding, and he still collects 90% of his damages from the driver who failed to yield.

That's exactly why insurers lean so hard on riders. In states with a cutoff, being 50% or more at fault wipes out the payout entirely. Arizona has no cutoff, but every percentage point pinned on you comes straight off the check. How you handle the claim from day one shapes the number, so it pays to read up on how to maximize your accident settlement in Arizona before the adjuster's first call, not after.

The severe reality of "left-hook" motorcycle injuries

A left-hook looks like this: the car cuts across the lane, and the rider either slams into its side or gets thrown over the hood. In fatal two-vehicle crashes, the motorcycle takes the impact on its front end 79% of the time, according to NHTSA.

The injuries that follow are usually severe:

• Traumatic brain injury (TBI), which even a helmet doesn't always stop
• Broken legs, a shattered pelvis, cracked ribs, and internal bleeding that may not surface right away
• Road rash deep enough to need skin grafts
• Spinal cord injuries that can end in paralysis

In 2023 alone, 258 motorcyclists died on Arizona roads, more than in any year in two decades (ADOT). The state only requires helmets under 18, so adults ride with no legal duty to wear one (more on Arizona's motorcycle helmet law). Treatment for a serious brain or spinal injury clears $500,000 without much trouble, and rehab can push it past $1,000,000. The at-fault driver's minimum coverage in Arizona is just $25,000, which won't even cover the first days in the ICU at Banner University Medical Center or Barrow Neurological Institute.

Why you need a Phoenix motorcycle accident attorney

Insurers come to motorcyclists with a bias already loaded. The default assumption is that the rider was flying, weaving between lanes, and brought it on himself. Hence the driver's favorite line: I never saw him. He isn't technically lying. A brain behind the wheel is scanning for other cars and simply doesn't register the narrow shape of a motorcycle. Legally, that's no excuse. Not seeing him doesn't erase the duty to yield under § 28-772.

Evidence breaks that logic. An experienced motorcycle injury attorney in Phoenix pulls camera footage, brings in an accident reconstruction expert, works out speed from skid marks and crushed metal, and rebuilds the driver's line of sight. One person's word against another's turns into a concrete picture of who did what.

Kermani LLP works on contingency: you pay a fee only if we win. The first consultation is free, and it's a chance to walk through exactly what happened at that intersection.
