The driver says they never saw you. The report notes the motorcycle was “travelling at speed.” Nobody measured anything. And just like that, the claim starts from the assumption that the rider was at fault.
That assumption is the single biggest obstacle in Arizona motorcycle claims, and it shows up before any evidence does.
The left turn problem
The most common serious motorcycle collision is a car turning left across the rider’s path at an intersection. The driver misjudges the bike’s speed or does not register it at all, because a motorcycle presents a much smaller visual profile than a car.
Legally, the turning driver owes the duty to yield. Practically, insurers still open these files looking for a reason the rider contributed. Intersection camera footage, if it exists, settles the argument faster than anything else, and it does not last long.
Helmets and what the law actually says
Arizona requires helmets only for riders under eighteen, under A.R.S. § 28-964. Riders over eighteen may legally ride without one.
That distinction matters because insurers sometimes argue that not wearing a helmet reduces recovery. Riding legally without a helmet is not negligence, though the medical picture in a head injury case is obviously affected. The legal argument and the medical one are separate, and they should be kept separate.
Lane filtering is legal in Arizona now
Since 2022, A.R.S. § 28-903 permits limited lane filtering. A rider may move between lanes of stopped traffic on a road with a speed limit of 45 mph or less, at no more than 15 mph.
Insurers regularly conflate filtering with lane splitting at speed, which remains unlawful. Getting the distinction right matters, because the difference between a legal manoeuvre and an illegal one changes the fault analysis completely.
Comparative fault works in the rider’s favour
Arizona uses pure comparative negligence under A.R.S. § 12-2505. Even a rider assigned a significant share of fault still recovers, reduced by that share.
Riders often assume that any contribution ends the case. It does not. That single misunderstanding causes people to accept early offers that assume far more rider fault than the evidence supports.
Why the injuries change the claim
Riders take the impact directly. Road rash requiring debridement, fractures needing hardware, and traumatic brain injury are all far more common than in car collisions, and the treatment runs longer.
Longer treatment means a claim should not be valued early. An offer that arrives before the orthopaedic picture is settled is an offer made without the facts.
At the scene, if you are able
Photograph the bike where it came to rest, not after it has been moved. Photograph the car, both vehicles’ damage, the road surface and the sightlines from the driver’s position. That last one matters more than people expect, because “I never saw the motorcycle” is much weaker when the photographs show a clear line of sight.
Get the names of anyone who stopped, not just the ones the officer speaks to. Riders are frequently taken to hospital before statements are gathered, and a witness who saw the car turn without indicating is often the difference in a disputed-fault case.
What helps most
Photographs of the bike, the road and the sightlines. The names of anyone who stopped. A request to preserve nearby camera footage the same week. Consistent medical treatment. And a careful read of the police narrative, because the phrase “unable to avoid the motorcycle” appears in far more reports than it deserves to.
