Parking lots produce a huge share of all vehicle collisions, and Phoenix-metro lots — grocery stores, malls, stadium events — are no exception. The speeds are low, but the injuries are real: whiplash, pedestrian knockdowns, and back injuries don't need highway speeds to happen. And because most lots are private property, these claims work differently than street crashes.
Right-of-way in a parking lot
Arizona's rules of the road formally govern public streets, but the same negligence principles decide parking lot fault, and insurers apply a consistent hierarchy:
- Pedestrians first. Drivers owe due care to pedestrians everywhere, and lots are full of them — including children below hood height.
- Through-lanes over feeder aisles. The main perimeter lanes that connect to street exits have priority. A driver leaving a parking aisle must yield to traffic in the through-lane, like entering a road from a driveway.
- Moving traffic over backing vehicles. A driver reversing out of a space must yield to everything — vehicles and pedestrians. Backing drivers carry the initial presumption of fault in most backing collisions, backup cameras notwithstanding.
- Two backing vehicles. When two cars back into each other, fault is usually shared and argued over timing — who was established in motion first, and who should have seen whom.
Cutting diagonally across empty spaces, ignoring painted arrows in one-way aisles, and speeding through lanes all shift fault onto the driver doing it.
Police usually won't come — plan accordingly
For minor collisions on private property with no injuries, Phoenix-area police departments typically don't respond or write a report. That surprises people, and it means the evidence burden is on you:
- Photograph everything before moving cars: both vehicles' positions, damage, the aisle layout, painted arrows and stop bars, and the wide shot showing where in the lot it happened.
- Get the other driver's license, insurance, and plate — photographed, not hand-copied.
- Collect witness names and numbers on the spot; parking lot witnesses walk away in seconds.
- Request camera footage fast. Most commercial lots are covered by store or property cameras, and retention is often measured in days. A same-week written request — or an attorney's preservation letter — is the difference between having the collision on video and having a word-against-word case.
- If anyone is injured, call 911 regardless. Injury changes the response, and the EMS record itself becomes evidence.
Fault fights and comparative fault
With no police report, both insurers hear competing stories and often try to split fault 50/50 by default. Arizona's pure comparative fault rule (A.R.S. § 12-2505) means every percentage point matters — a shift from 50/50 to 20/80 changes the recovery dramatically. Video, photos, and vehicle damage patterns (where each car was struck, and how hard) are what move those numbers.
When a parking lot crash becomes an injury case
Low-speed doesn't mean low-injury — soft-tissue and spine injuries from parking lot impacts are common, and pedestrians struck by backing vehicles can be seriously hurt. If the lot's condition contributed — broken lighting, missing signage, blind corners created by cart corrals or landscaping — the property owner may share liability under premises liability principles. See our premises liability page for how those claims work.
