Mutual lane-change crash, both at fault per officer — do I call my insurance or just wait?

Almost the exact same thing happened to me about two years ago — shared fault, minor-ish damage, officer said we could handle it however we wanted. I decided to wait and see. The other driver ended up filing with their insurance like three weeks later, and my insurer was kind of annoyed I hadn't given them any heads-up. They still handled it, but the rep made it clear it's better to loop them in early even if you're not formally filing a claim. I'd at least make a quick call just to document that it happened.

Here's the thing people don't realize: the other driver can file against you weeks or even months from now depending on your state's rules. If you haven't told your insurer anything and a claim suddenly lands on their desk, you could look like you were trying to hide something. Doesn't matter how cooperative you were at the scene. Insurance companies love any reason to make your life harder. Call them today, keep it short, just say you're reporting an incident — you don't have to say 'I'm filing a claim' right away.

Worked in auto claims for a long time. 'Notifying' and 'filing a claim' are two different things — most people don't know that. You can call your insurer, tell them what happened, give them the date and other driver's info, and explicitly say you're not filing a claim at this time. It goes into their system as a reported incident. That way if the other party files against you later, your insurer already has context and you don't look like you were caught off guard. Protect yourself. One five-minute call does it.

Most auto policies have a clause requiring 'prompt' or 'timely' notification of accidents — not just claims, but accidents. The exact language varies by policy but failing to notify can sometimes give the insurer grounds to push back on coverage later if a dispute comes up. I'd pull out your policy documents tonight and look for the notification requirements section. And yeah, just call. The call itself doesn't trigger a rate increase — a paid claim does.

Not legal advice, but since fault was split, there's potential exposure here even if it feels minor. If the other driver decides their damage is more serious than it looked, or claims some delayed physical discomfort, you want your insurer in your corner from the start. Shared fault doesn't mean zero liability. Definitely notify your carrier sooner rather than later.

Just want to flag — you said no one was hurt, which is great. But sometimes soft tissue stuff from even a low-speed impact doesn't show up for 24–48 hours. Keep an eye on how you're feeling over the next couple of days. Neck stiffness, headaches, shoulder ache. Hopefully nothing, but if something comes up, see someone and document it. Better to have a record than to shrug it off.

Call your insurance today. Don't overthink it. Tell them what happened, give them the other driver's info, and say you're not filing yet but wanted to report it. Done. Sitting and hoping nothing happens is the one thing that can actually make this worse.

How bad is 'harder hit' on their rear door — are we talking a scuff that pops out or is the door actually deformed? That changes things a lot. If their damage is significant, the odds they file go way up, and then you really want to have already talked to your insurer.
