Arizona’s beautiful weather and scenic roads make bicycling a popular choice for commuting, exercise, and recreation.  But with more cyclists on the road, accidents involving cars and bikes are also on the rise.

When a driver fails to share the road safely, the consequences for a cyclist can be devastating.  Understanding who may be held liable after a bicycle accident is essential for protecting your rights and pursuing compensation.

Arizona’s Rules for Drivers and Cyclists

Under Arizona law, bicycles are considered vehicles.  This means cyclists have the same rights and responsibilities as drivers of cars.  Drivers are legally required to:

  • Give cyclists at least 3 feet of space when passing
  • Yield to cyclists when turning if the cyclist has the right of way
  • Avoid aggressive driving, honking, or “dooring” (opening car door in a cyclist’s path)
  • Follow posted traffic signs and signals that apply to all road users

When drivers fail to uphold these duties, accidents often happen.

Common Causes of Bicycle Accidents

Bicycle accidents frequently occur because of:

  • Distracted driving (texting, talking, or eating behind the wheel)
  • Failing to yield at intersections
  • Unsafe lane changes or “close passes”
  • Opening car doors into a cyclist’s path
  • Speeding or reckless driving
  • Driving under the influence

Even a minor collision can result in serious injuries for cyclists, including broken bones, head injuries, spinal injuries, and long-term trauma.

Who Can Be Liable in a Bicycle Accident?

Liability depends on the details of the crash.  Potentially responsible parties may include:

Motor Vehicle Drivers – Most commonly, drivers are at fault when they fail to share the road or violate traffic laws.

Cyclists – If a cyclist ignores traffic signals, rides against traffic, or behaves recklessly, they may share some responsibility.

Municipalities or Property Owners – Poorly maintained roads, missing signage, or hazardous construction zones can also contribute to liability.

Vehicle or Equipment Manufacturers – If a defective car part (like failed brakes) or faulty bike component played a role, manufacturers may be liable.

Arizona’s Comparative Negligence Law

Arizona follows a pure comparative negligence system.  This means that even if a cyclist is partly at fault, they can still recover compensation—though their award is reduced by their percentage of fault.  For example if a cyclist is awarded $100,000 in damages but found 20% at fault, they would still receive $80,000.  This law makes it even more important to work with an attorney who can maximize your recovery.

Final Thoughts

Cyclists have the right to feel safe on Arizona roads.  When drivers don’t share that responsibility, serious accidents happen—and the law provides ways for injured cyclists to pursue justice.  If you or a loved one have been injured in a bicycle accident, you don’t have to face the aftermath alone.
