Two cars bump mirrors in a parking lot, both drivers get out, both say sorry, and somehow the whole thing settles into a shrug. Nobody was speeding, nobody ran a light, so the assumption takes hold: it's 50/50, that's just how parking lots work. This is one of those beliefs that feels true because it gets repeated so often, but fault in a parking lot collision is determined the same way it's determined anywhere else, by looking at the circumstances and figuring out who did what wrong. The law doesn't treat parking lots as liability-free zones where responsibility evaporates the moment you leave a public road.
What actually matters is who had the right of way, which driver was moving and which was stationary, who was in a through lane and who was pulling out of a parking row, and whether anyone was backing up at the time. A car reversing out of a spot into a vehicle already traveling down the lane is in a fundamentally different position than two cars meeting head-on in a narrow aisle. A driver who's already stopped when the other car rolls into them isn't sharing blame just because the whole thing happened at low speed. The facts control the outcome, and plenty of parking lot collisions end with one party bearing most or all of the fault because the facts clearly point that way.
The 50/50 assumption survives partly because it's convenient. It lets everyone move on without argument, and in minor fender-benders the path of least resistance can be tempting. But for a sole proprietor whose work van just got dinged, or a small business with delivery vehicles and a direct stake in their claims record, accepting an even split on a collision that wasn't their fault has real consequences. An unfair liability finding follows the vehicle and the driver, affects costs, and creates a history that compounds over time. The stakes aren't theoretical when you're the one absorbing them.
The driver that can establish what actually happened is the one positioned to push back on a default split. That means recording the position of both vehicles, the direction of travel, whether one car was stopped, how the lanes and parking rows were laid out, whether any signage controlled the flow, and who if anyone was backing up. Witness contact information matters. Dashcam footage, or CCTV footage from surrounding businesses, if you have it, matters even more. None of this is complicated in the moment, but it's easy to skip when two drivers are standing in a lot exchanging mutual apologies and eager to leave. The person closest to the facts is the one best placed to run the claim, and recording those facts while they're fresh is what makes that possible.
Managing liability after a parking lot collision is claim management, not an insurance question. The issue is whether you can demonstrate who was at fault, and that demonstration rests on evidence you either gathered or didn't. A business owner with a vehicle in the field doesn't need a legal department on call, but they do need some way of capturing what happened and knowing when the default story isn't the real one. That's the kind of quiet readiness Binder exists to provide, something that watches for these moments and helps you respond when they arrive.
