A photo posted to 5ch’s Nandemo Jikkyo G board sparked a wide-ranging debate over fault ratios in a parking-lot collision. A kei (mini) truck carrying cargo — what looked like wooden beams — that jutted out past the truck bed backed into the rear of a parked car, and the image clearly shows the truck plowing into the stationary vehicle. While posters agreed from the start that “the truck is obviously at fault,” opinions split on several finer points: whether the driver was legally required to mark the protruding cargo with a red flag, whether a parking lot even counts as a “road” under traffic law, and whether the crash could have been avoided if the driver had been watching the backup monitor.
If a red cloth is actually required by traffic law, that'd shift the fault ratio.
Also, with this much open space around, why not just park somewhere else?
So many people insist on parking right next to other cars for some reason.
The black car just loses, plain and simple.
Apparently some people use nearby cars as a reference point when parking.
Length: up to 1.2x the vehicle's length (overhang of up to 1/10 (10%) of the vehicle's length is allowed front and back).
Did you guys lose again?
A parking lot isn't a public road, so… 😅
Buddy, the length limit has changed since you last checked.
It's not a road.
Yeah, true, it's not a road.
With a red marker it might — might — get close to 50-50.
"Sticking out past the white line" lol
That part means literally nothing lol
If anything, this happened *because* he wasn't watching the backup monitor.
Honestly, wouldn't this be tough to catch even by eye?
Unless you get out and check before parking, I think pretty much anyone would've hit it.
It's not even next to another car though.
It's not about bashing anyone, it's about who's actually at fault. In this case the truck isn't guilty of anything — if anything, it's the victim.
What else could it be besides the one who crashed in being 100% at fault? The other car was just sitting there lol
Since it's a parking lot and the other car was completely stationary, the fault ratio is obviously going to lean hard against the one who was moving.
How the overhanging cargo on a parked vehicle factors in, though, is something a layman just can't say.
There's obviously some limit relative to the vehicle's length, sure, but this amount isn't something to worry about.
The lot's basically empty too.
He must have seen the beams sticking out when he was parking.
I wouldn't have parked here.
It's not a public road and the vehicle wasn't even moving, so the red marker isn't necessary.
Is a kei truck even 5 meters long?
Either way it's probably not 5m, but I think that's a 2-ton dump truck, not a kei truck.
Yeah, that sounds about right.
If it were a 2-ton dump truck, it wouldn't be sticking out this far under the legal standard.
And either way, letting it hang out the back instead of the front is just careless.
You can tell just by looking at the corners of the two vehicles — that's not a kei truck.
Even if a car has one, plenty of people don't use it.
Not many people set it to display by default, and hitting the switch button is a hassle.
Background and Key Points of the Debate
Fault ratios are determined case by case based on the parties’ circumstances and the judgment of insurers or courts — they can’t be settled definitively from a photo alone. The “cargo can overhang up to 10% of the vehicle’s length” standard that came up in the thread is based on vehicle safety regulations for road transport, and it’s premised on driving on public roads. Whether that standard carries over directly to private property like a parking lot is inherently a case-by-case question, and the claim that “it’s not a road, so there’s no obligation to use a red cloth” isn’t a settled legal conclusion either. Whether the cargo stuck out past the white line isn’t a factor that directly determines the fault ratio either — it’s just one piece of situational information. The fault-ratio figures posters got by showing the photo to an AI chatbot are likewise only a rough reference point, not a legal basis for determining actual insurance grading or damages.
