Parking Lot Accident in Phoenix: Who Is Liable?

Arizona traffic laws generally extend to private property, including parking lots. A.R.S. 28-651 prohibits drivers from using private property to avoid traffic control devices, and general negligence principles apply to all driving situations. Fault in parking lot accidents is determined by whether each driver acted as a reasonable person would under the circumstances. This makes parking lot fault determinations fact-intensive and often contested.

In practice, a consistent hierarchy governs parking lot right-of-way. Vehicles in the main travel lane (the thoroughfare that runs along storefronts) have priority over vehicles in feeder lanes. Vehicles in any travel lane have priority over vehicles pulling out of or backing out of parking spaces. Pedestrians have priority over all vehicles. A driver backing out of a space who strikes a vehicle in the travel lane will almost always bear the majority of fault.

Shared fault is the norm in parking lot accidents. Two cars backing out simultaneously, a driver in the travel lane going too fast, or a vehicle cutting through empty spaces instead of using designated lanes — all of these create shared liability. Under Arizona's pure comparative negligence system, the precise fault percentages assigned to each party determine the outcome. Unlike many states, Arizona has no threshold bar — you can recover damages at any fault percentage.

Arizona follows pure comparative negligence under A.R.S. 12-2505. This is one of the most favorable fault rules in the country for injured people. Your damages are reduced by your percentage of fault, but you are never completely barred from recovery. If you are 40% at fault and your damages are $50,000, you recover $30,000. If you are 80% at fault, you still recover $10,000.

This matters enormously in parking lot accidents, where shared fault is common. In states with a 50% bar (like Tennessee or Ohio), being found 50% or more at fault means you recover nothing. In Arizona, you always recover something — as long as the other party bears at least some fault. This changes the entire dynamics of parking lot accident claims in your favor.

The exception under A.R.S. 12-2505 is if the injured person intentionally, willfully, or wantonly caused the injury. Standard negligence — misjudging a turn, backing out without checking mirrors — is not intentional conduct. This exception applies to extreme situations, not ordinary parking lot accidents.

The property owner or business operating the parking lot may share liability for your accident if the lot's design or maintenance contributed to the crash. Under Arizona premises liability law, property owners owe a duty of care to maintain reasonably safe conditions for visitors. Common defects that create liability include inadequate lighting, poorly marked lanes and traffic flow, missing or obscured signage, blind corners created by landscaping or structures, faded line markings, and potholes or uneven surfaces.

Phoenix's intense sun and heat degrade parking lot markings faster than in most cities. Faded lane lines, worn directional arrows, and sun-bleached signage are common problems that create confusion and contribute to accidents. If the property owner failed to maintain clear markings, that failure may constitute negligence.

To pursue a premises liability claim against the property owner, you need evidence of the unsafe condition. Photograph the lighting, signage, sight lines, and any defects immediately after the accident. Note whether the lot had security cameras — footage may show the property owner knew about the hazard. Property owners who receive frequent complaints or prior accident reports about the same hazard face stronger liability arguments.

Stop immediately and check for injuries. Even low-speed parking lot collisions can cause whiplash, concussions, and back injuries — do not assume you are fine because the speed was low. Exchange insurance information, driver's license numbers, and contact information with the other driver. Take photographs of both vehicles' damage, license plates, the parking lot layout, any relevant signage, and the exact location of the accident.

Report the accident to the store or property manager. Ask if there is surveillance camera footage and request that it be preserved. Many parking lots have cameras, and footage is critical for establishing fault — but it gets overwritten quickly. If the business will not voluntarily preserve footage, an attorney can send a preservation letter.

Call Phoenix Police to file a report. Officers may not respond to property-damage-only accidents on private property, but you can file a report by calling 602-262-6151. Having a police report — even one filed after the fact — strengthens your insurance claim. If there are injuries, call 911 and officers will respond.

Two vehicles backing out of opposite spaces at the same time: fault is typically split 50/50, though the driver who had more visibility or started backing out first may bear less fault. Both drivers have a duty to check their surroundings before backing. Under Arizona's pure comparative negligence, both drivers can recover from each other — each reduced by their fault percentage.

Vehicle backing out of a space hits a car in the travel lane: the backing driver almost always bears the majority of fault. The travel lane driver has the right-of-way. However, if the travel lane driver was speeding, texting, or otherwise not paying attention, they may share some fault. Arizona courts look at what each driver reasonably could have done to avoid the collision.

Vehicle hits a pedestrian in the parking lot: the driver almost always bears the majority of fault. Pedestrians have the right-of-way in parking lots, and drivers must maintain a careful lookout. Parking lot speeds should be 5 to 10 mph. Hitting a pedestrian at any speed in a parking lot creates strong liability for the driver, though pedestrians who dart out from between parked cars without looking may share some fault.

Report the accident to your insurance company promptly. Arizona is a fault-based state, so the at-fault driver's insurance is responsible for your damages. If fault is shared — which is common in parking lot accidents — insurers will negotiate fault percentages. Your recovery from the other driver's insurer is reduced by your fault percentage under Arizona's comparative negligence rule.

If the other driver does not have insurance, your uninsured motorist (UM) coverage applies. Arizona insurers must offer UM coverage under A.R.S. 20-259.01. If the other driver fled (a parking lot hit and run), UM coverage also applies. Arizona's minimum liability limits are $25,000 per person, $50,000 per accident for bodily injury, and $15,000 for property damage.

For property-damage-only parking lot accidents, you may need to use your collision coverage and then seek reimbursement from the at-fault driver's insurer. If your vehicle was legally parked and struck by another vehicle, you bear no fault and the other driver's insurer should cover all your damages. Keep repair estimates, photographs of damage, and rental car receipts as documentation.

Arizona's statute of limitations for personal injury is 2 years from the date of injury (A.R.S. 12-542). For property damage claims, the deadline is also 2 years under A.R.S. 12-542. Missing this deadline means the court will almost certainly dismiss your case.

For premises liability claims against the property owner, the same 2-year deadline applies. If the property owner is a government entity — a city-owned parking garage, a government building parking lot — you must file a notice of claim within 180 days under A.R.S. 12-821.01. This much shorter deadline applies regardless of the general 2-year statute.

Do not assume a parking lot accident is too minor to pursue. Whiplash, concussions, and back injuries from low-speed impacts can require months of treatment and cause chronic pain. Medical costs add up quickly. If you were injured in a parking lot accident, start building your case promptly — gather evidence, see a doctor, and understand your legal options.
