Whose fault is this?

The one who rear ended first. Yes, the guy was stopped, but he may have had a reason. It is the responsibility of every driver to pay attention to other cars on the road.

The inbred Somali driver . Probably

The red SUV was the cause really. But officially the silver van that rear ended the other car.

The dumbass in the big gray van.

The minivan could have been cited also

Do you have insurance to cover this situation?

I love how the red van that had initially stopped changes lanes right after they got bumped from the accident. I'm betting it was a teenage driver.

70% gray van, 30% red van... Notice also how the red van drives over the hash marks. Shitty driver. I swear ther are so many drivers who don't do anything illegal per se but by their bad driving cause so many accidents.

The van's fault. He hit something in front of him

The cyclist.

Red van may have been having mechanical issue or medical emergency but mostly likely just an idiot who missed their exit. Doesn't matter. Silver van wasn't paying attention.
