Bicycle Accident Rights in Arizona — What Cyclists Need to Know

Arizona law gives bicyclists the same rights and responsibilities as motor vehicle drivers. Under A.R.S. § 28-812, a bicycle on the roadway is a vehicle — entitled to use the road and protected by the same traffic laws. When a driver hits a cyclist, the cyclist has full legal rights to pursue compensation.

Why Bicycle Accidents Are So Severe

Like motorcycle accidents, bicycle crashes involve a massive weight disparity. A cyclist has zero protection — no steel frame, no airbags, no seatbelt. Common injuries include traumatic brain injury (even with a helmet), broken bones (clavicle, wrist, pelvis), road rash requiring skin grafts, spinal cord injuries, and internal organ damage.

Common Causes

Drivers hit cyclists most often by failing to check before turning right (“right hook”), opening car doors into bike lanes (“dooring”), passing too closely — Arizona law requires a minimum 3-foot gap, failing to yield at intersections, and distracted driving — not seeing the cyclist at all.

Helmet Laws and Comparative Fault

Arizona does not require adult cyclists to wear helmets. But if you weren’t wearing one, the insurance company may argue comparative fault — claiming a helmet would have reduced your head injuries. This argument is legally questionable but commonly raised.

What to Do After a Bicycle Crash

Don’t move your bike until photos are taken — the position of the vehicles tells the story. Get the driver’s information and insurance details. Look for witnesses and cameras. Get medical attention — adrenaline masks injuries. And call the Law Badgers at (833) DTF-IGHT.
