Parking Lot Accident in Des Moines: Your Rights and Next Steps

Iowa's general traffic rules apply in parking lots, but the layout of most parking lots creates unique right-of-way situations. The basic rule: drivers in through-lanes — the main driving lanes that connect to the lot's entrances and exits — have the right of way over drivers entering the through-lane from a parking space, row aisle, or side lane.

Drivers backing out of a parking space must yield to all approaching traffic in the travel lane. This means the driver backing out is usually at fault if they collide with a vehicle driving through the lane. However, this is not absolute — if the through-lane driver was speeding, distracted, or failed to take reasonable evasive action, they may share fault under Iowa's comparative fault system.

At intersections within the parking lot (where two travel lanes cross), standard right-of-way rules apply: the driver on the right generally has the right of way, and posted stop signs and directional arrows establish priority. Many parking lot accidents happen because drivers ignore these posted signs or assume the other driver will stop.

One of the most common parking lot scenarios is two vehicles backing out of opposing spaces simultaneously and colliding in the travel lane. In this situation, fault is typically split between both drivers, since both had a duty to check for traffic before backing out and neither had right-of-way over the other.

Under Iowa's comparative fault system (Iowa Code § 668.3), if fault is split 50/50, each driver can still recover 50% of their damages from the other. If one driver was backing out faster, failed to check mirrors, or ignored a backup camera alert, they may bear a greater share of fault. The specific circumstances — speed, visibility, attentiveness — determine the exact split.

Document this type of accident carefully. Photograph both vehicles' positions, the parking space layout, sight lines, and any mirrors or backup cameras. Note which direction each vehicle was facing and how far each had backed out. These details help establish which driver was less careful, which directly affects the fault allocation.

Most Des Moines parking lots — shopping centers, grocery stores, office complexes — are private property. This creates several practical complications. Des Moines Police may decline to respond to accidents on private property, especially if there are no injuries. Without a police response, there is no official crash report, which means you need to document everything yourself.

If police do not respond, exchange information with the other driver: names, driver's license numbers, insurance information, phone numbers, and license plate numbers. Photograph everything — both vehicles, the damage, the parking lot layout, any posted signs, and the other driver's documents. This documentation serves the same function as a police report for your insurance claim.

The private property status does not change your legal rights. Iowa's fault laws, insurance obligations, and statute of limitations apply identically whether the accident happened on a public road or in a Hy-Vee parking lot. You can file an insurance claim and pursue a personal injury lawsuit just as you would for any other car accident.

Security cameras are the single most valuable evidence source in parking lot accidents. They provide objective, timestamped footage showing exactly what happened — who was backing out, who had the right of way, who was distracted, and how the collision occurred. This footage can resolve fault disputes that would otherwise devolve into he-said/she-said.

Act immediately to preserve footage. Most commercial security systems in Des Moines overwrite footage on a rolling 7 to 30 day cycle. Go to the business or property management office the same day as the accident and request that the footage be preserved. Get the name and contact information of the person you speak with. Follow up with a written request by email or letter.

If the property owner or business refuses to preserve footage, an attorney can send a formal preservation letter (also called a spoliation letter) that creates legal consequences for destroying the evidence. If you anticipate filing a claim, having an attorney send this letter promptly can make the difference between winning and losing a disputed fault case.

Insurance companies routinely downplay parking lot injuries because the speeds involved are low — typically 5 to 15 mph. But speed alone does not determine injury severity. The direction of impact, whether the occupant was braced for the collision, the angle of the occupant's head and neck, and the vehicle's structural response all affect injury outcomes.

Whiplash — the most common parking lot accident injury — can occur at speeds as low as 5 mph. When you are stationary in a parked car or slowly driving through a lot and another vehicle strikes you unexpectedly, your body is completely unbraced. The sudden acceleration of your torso while your head remains momentarily stationary snaps the neck through a rapid flexion-extension cycle, straining ligaments, muscles, and potentially discs in the cervical spine.

Other common parking lot crash injuries include concussion (from head striking the headrest, steering wheel, or window), back strain, shoulder injuries from seatbelt loading, and wrist injuries from gripping the steering wheel. If you feel any pain, stiffness, or dizziness after a parking lot crash — even hours later — seek medical attention. MercyOne and UnityPoint Health urgent care clinics throughout Des Moines can evaluate and document these injuries.

Report the accident to your insurance company promptly, even if you believe the other driver was entirely at fault. Your policy likely requires timely reporting of all accidents. If you have collision coverage, your insurer can pay for your vehicle repairs (minus your deductible) and then pursue reimbursement from the other driver's insurer through subrogation.

If the other driver is clearly at fault — for example, they backed into your stationary vehicle — you can also file a third-party claim directly with their insurance company. Provide the other driver's insurance information, your documentation (photos, witness statements), and a clear description of what happened. The other driver's insurer will investigate and, if their driver was at fault, pay for your damages.

Without a police report, expect the claims process to take longer. Both insurers will rely on the available evidence — photographs, your statements, the other driver's statements, and any surveillance footage — to determine fault. Consistent, detailed documentation from the scene is your strongest tool for getting the claim resolved in your favor.

Iowa's modified comparative fault system (Iowa Code § 668.3) affects parking lot accident claims the same way it affects any other crash. If you are partly at fault — for example, you were checking your phone while driving through the lot when someone backed into you — your recovery is reduced by your fault percentage.

If you are 51% or more at fault, you recover nothing. This matters in parking lot accidents because fault is frequently shared. Both drivers may have been inattentive, both may have been moving, or the sight lines may have been obstructed. The insurer will assign fault percentages based on the evidence and circumstances.

Protect yourself by being completely honest but strategic in how you describe the accident. Do not volunteer speculation about what you could have done differently. State the facts: your speed, your actions, what you observed, and how the other vehicle struck yours. Let the evidence speak — and make sure you have strong evidence by documenting the scene thoroughly.
