E-bikes and electric scooters have become a common sight on streets from Phoenix to Scottsdale, and a ride can turn into a serious injury faster than most people expect. Big Auto Accident Attorneys built its national reputation on cases just like these, pairing local Arizona attorneys with a nationwide network of co-counsel to win results insurers never expect to pay, all on a no-win, no-fee basis. That experience makes a marked difference because liability in an e-bike or scooter crash is rarely as simple as it looks. Arizona treats the rider, the other driver, and sometimes a scooter-share company differently than it would in a typical car accident. Below is a breakdown of who can be held responsible and how Arizona's traffic and insurance laws shape these claims.
What Counts as an E-Bike or Scooter Under Arizona Law?
Arizona law defines electric bicycles and electric standup scooters under A.R.S. § 28-819, which sorts e-bikes into three classes based on top assisted speed and whether the motor works with or without pedaling:
- Class 1: Pedal-assist only, with a motor that stops assisting at 20 mph.
- Class 2: Throttle-assisted, with a motor that stops assisting at 20 mph.
- Class 3: Pedal-assist only, with a motor that stops assisting at 28 mph.
Motor-driven cycles, a separate and faster category defined under A.R.S. § 28-101(48), are treated more like motorcycles and require registration, insurance, and a motorcycle-endorsed license. Getting this classification right matters because it determines which rules and insurance requirements apply to your accident.
Are Riders Held to the Same Rules as Drivers?
Yes. Under A.R.S. § 28-819(A), an operator of an electric bicycle or electric standup scooter is granted the same rights and subject to the same duties as a person riding a traditional bicycle. This means riders must:
- Obey traffic signals and stop signs
- Use hand signals when turning or changing lanes
- Yield to other traffic and pedestrians when the law requires it
A rider who runs a stop sign or swerves without signaling can share fault for a resulting crash.
Who Can Be Held Liable in an Arizona E-Bike or Scooter Accident?
- A negligent driver who failed to yield, was distracted, or was speeding
- The e-bike or scooter rider, if they violated a traffic law that contributed to the crash
- A scooter-share or rental company, if a mechanical defect or poor maintenance played a role
- A city or county, if a poorly maintained road or bike lane creates a dangerous condition
- A manufacturer, if a defective brake, battery, or motor caused the crash
How Arizona's Comparative Negligence Rule Affects Your Claim
Arizona follows a pure comparative negligence system under A.R.S. § 12-2505, which means an injured rider can still recover damages even if they share some fault for the accident. The rider's percentage of responsibility simply reduces compensation, so a rider found 20 percent at fault can still recover 80 percent of their damages. No cutoff point entirely bars recovery.
What If the At-Fault Driver Is Uninsured or Underinsured?
Many e-bike and scooter crashes involve drivers who lack adequate insurance, and Arizona requires insurers to offer uninsured and underinsured motorist coverage under A.R.S. § 20-259.01. A rider's own UM or UIM coverage, if purchased through a household auto policy, can become an important source of recovery when the at-fault driver cannot fully cover the injury.
