Can you really tell who's at fault from dashcam footage alone? Need some clarity

Oh man, I went through almost exactly this — I had dashcam footage from my own car and my adjuster absolutely used it to argue I had time to react and didn't. I didn't even realize they could do that until it was too late. Definitely tell your cousin to be careful about who she hands that video over to and when.

Former adjuster here. Yes, adjusters absolutely analyze dashcam footage frame by frame when it's available — and yes, that includes footage the claimant provides. Reaction time, following distance, speed — all of it gets scrutinized. The footage doesn't automatically help just because it came from her camera. If there's any ambiguity in that clip, the company will interpret it in the way that benefits them. That's just how it works. I'm not saying hide evidence — don't do that — but she should understand what she's handing over before she does it.

The adjuster saying 'let's split fault' this early in the process is a classic move. They float that out there before a full investigation is done to see if you'll just accept it and go away. Your cousin shouldn't agree to anything or sign anything until she fully understands what that split actually means for her claim and her future premiums.

Not legal advice, but a few things worth knowing: dashcam footage can definitely be used by either side, and fault is rarely determined by video alone — road conditions, witness statements, the police report, and sometimes accident reconstruction all factor in. The reaction time question is genuinely interesting legally because it can go either direction depending on how it's framed. If her neck stiffness persists, she should see a doctor and document it sooner rather than later. That part matters more than people realize.

Please tell your cousin not to brush off the neck stiffness. I've seen so many people shrug off post-accident soreness and then two weeks later they're in real pain. Soft tissue injuries don't always show up immediately. She should get checked out, even just at an urgent care, and make sure it's documented. Not just for legal reasons — for her own health.

From a process standpoint: she should make sure she has a copy of that footage saved somewhere secure and backed up before sharing it with anyone. Once it's out there, it's out there. Also, if there was a police report filed, she should request a copy ASAP — sometimes the officer's notes include observations about the other driver's behavior that can really support or complicate the story the video tells.

I don't want to be harsh but — how long is the footage? Does it show what was happening the full 10-15 seconds before the merge? Because a short clip starting right at the collision moment tells a very different story than one showing the full lead-up. Context is everything with this stuff.
