3-car chain reaction — one driver uninsured — which coverage actually applies here?

Hey everyone, hoping someone has dealt with something like this before because my brain is fried trying to figure out the coverage angle.

So I was stopped at a red light, first car in line. Behind me, a delivery van rear-ended a sedan, which sent the sedan flying into my bumper. The sedan driver — the one who physically hit me — turns out has zero insurance. The delivery van that started the whole thing does have insurance.

Here's where I'm confused: the sedan is what made contact with my car, but it was basically a projectile at that point. The van driver caused the whole thing. So who am I actually filing against?

My own policy has both uninsured motorist (UM) and collision coverage. The deductibles are different — UM is a bit lower, which obviously matters to me right now since my car has a decent amount of damage.

I've been going back and forth reading my policy documents and honestly it's written in a way that feels deliberately confusing. One section seems to say UM only applies when the uninsured vehicle is the proximate cause, another part just says direct physical contact.

Has anyone been in a multi-car pileup where one of the drivers was uninsured? Did your insurance company try to push you toward collision (higher deductible) even when UM seemed like it should apply? I don't want to just take whatever they tell me without understanding my options first.

Also — do I need to file against both drivers separately, or does one claim cover everything?

Any insight is genuinely appreciated. This whole thing happened so fast and I'm still kind of shaken up.

Ugh, I had something weirdly similar last year — chain reaction, one uninsured driver in the middle of it. My insurer initially tried to run everything through collision and I had to push back hard. Ended up being a mix of both claims. Definitely don't just accept the first thing they tell you.

Of course they're going to steer you toward collision if they can — that's more deductible money out of YOUR pocket instead of them pursuing the van's insurance. They do this constantly. Ask specifically and in writing which coverage they're applying and why. Make them explain the proximate cause determination. The squeaky wheel really does get the grease with these people.

  You can technically file against both simultaneously — van's liability AND your own UM — and let them sort out contribution between insurers. You don't have to pick just one right now. Document everything: photos, the police report, any witness info. The 'direct physical contact' language in UM policies varies a lot by state so it's worth looking up your specific state's rules or having someone review your actual policy language.

Okay so from the inside view — proximate cause is genuinely the key question here. If the van set the whole chain in motion, a lot of adjusters will actually route this toward the van's liability coverage first, which would mean you might not even need to touch your own UM or collision. The uninsured sedan driver is kind of irrelevant if the van's insurer accepts liability for the whole event.

That said, adjusters aren't always consistent. Some will just default to whatever is easiest to process on their end. I'd ask the van's insurance company directly if they're accepting liability for your damages too — not just the sedan driver's damages.

Not legal advice, but this is genuinely a proximate cause question that comes up more than people realize. The vehicle that physically touched yours isn't automatically the one 'at fault' in the legal sense — courts look at who set the events in motion. If the van is the root cause, their carrier may owe you directly. Worth at least a free consult with a PI attorney before you settle anything, because how you characterize the claim early can affect what you recover later.

Please don't forget to get checked out medically even if you feel okay right now. Adrenaline masks a lot and rear-impact whiplash especially can sneak up on you 24-48 hours later. Make sure any symptoms get documented by a doctor sooner rather than later — it matters for your claim too, not just your health.

Short answer: file against the van's insurance for liability first. If they drag their feet or deny, THEN go to your UM. Don't lead with your own policy if you don't have to — you'd be paying a deductible for someone else's mess. Be firm and don't let either insurer tell you it's 'unclear' without a real explanation.

This sounds so stressful, I'm sorry you're dealing with all of this on top of just recovering from the shock of the accident. Are you doing okay otherwise? The coverage stuff is important but make sure you're also taking care of yourself.
