Other driver's insurer says I cut them off — dashcam shows I was fully merged. What now?

Almost the exact same thing happened to me — merging situation, rear-end hit, and their insurance immediately blamed me. I filed through my own insurer and they went to bat for me in subrogation. Took a few months but I eventually got my deductible back. It's annoying to front the money but honestly it was worth not fighting the other company alone.

That denial after 'reviewing the dashcam' without even looking at damage photos is a huge red flag. They made up their minds before doing a real investigation. Adjusters do this hoping you'll just give up and go away. Don't. The damage pattern alone — all rear, no side — directly contradicts their version of events. Document everything, including that detail about them not reviewing your photos when they first denied you.

I used to do this job and I'll be honest — a quick denial on a merge claim is sometimes a first-pass tactic to see if the claimant pushes back. The fact that they upheld it on reconsideration internally doesn't surprise me either; those reviews are often done by the same team. Your real leverage is subrogation through your own carrier or filing a complaint with your state's insurance commissioner. Both put actual pressure on them in a way that a phone call to the claims line doesn't.

A few things worth knowing: when your insurer goes after theirs through subrogation or arbitration, they're arguing on your behalf — and inter-company arbitration tends to look pretty hard at physical evidence like damage location and video. Rear-only damage plus dashcam showing you fully merged is a strong factual record. Make sure you preserve that footage in multiple places and don't let the camera overwrite it. Also — filing a complaint with your state insurance regulator about the quality of their investigation costs you nothing and sometimes shakes things loose.

File through your own insurance. Yes, the deductible stings upfront. But your carrier has actual leverage over theirs — you don't. Solo-fighting a denial against another company's adjuster team almost never goes anywhere. Let the insurers fight it out and get your car fixed now.

Quick question — does your dashcam have a forward-facing view only, or does it capture the rear too? And does it show the moment of the actual merge, or does footage start after you're already in the lane? I'm not doubting you at all, just wondering how much of the full sequence is actually captured, because that might affect how useful it is in arbitration.

This sounds so stressful, especially when you have the video and they're still saying it's your fault. I really hope you get this sorted — it sounds like the evidence is clearly on your side and it's just a matter of getting someone who'll actually look at it fairly.

The good news is you're actually in a stronger position than most people in disputed claims — you have timestamped footage and physical damage that matches your account. A lot of people are fighting these things with nothing but their word. Hang in there, it's a slow process but the evidence working in your favor really does matter.
