A couple of months ago I was involved in a small fender bender. I turned right leaving a parking lot, which ended up being a right turn only lane and I needed to go straight. Naturally I began the process looking to merge left. The lane to the left was a turn right or go straight lane. I am looking into my left mirror to see if I have space to merge while also seeing which cars are turning right as I would have no other choice but to make the right turn if there was no opportunity, to avoid a T-bone like situation I notice plenty of space behind Vehicle A once they passed me up. As I am looking at my mirror, Vehicle A speeds up and doesn’t have their turn signal on, meaning they should be going straight. I slow down so they can pass me up and all of a sudden Vehicle A decides to make the right turn abruptly as if they were late to something. They did not see me, but I saw the car, beeped, and did my best to turn along with Vehicle A to mitigate any damage. We collided with typical fender bender cosmetic damages. Within 3 minutes between collision and pulling over, the drivers dad shows up out of nowhere and does the majority of the talking for her. He was saying things like “it’s up to you if you think the hassle of going through insurance is worth it” which I took as discouraging going through insurance because they felt they were in the wrong. The cop pulls up and is very quick to deem me at fault without any major details (Vehicle A had police plates lol). Cop gave major attitude when I asked how I can retrieve the traffic camera footage as it captured the incident perfectly. I also was not cited for anything. I was able to retrieve the traffic camera footage and submit as evidence to Vehicle A’s claim. I was on the phone with the adjuster as she reviewed the evidence with me. She told me it was most likely going to be deemed double fault for “unsafe lane change” and the opposing drivers failure to indicate a turn signal which the footage showed. I understood and was told I’d be contacted before a decision was made. The claim was closed mid February and I was never contacted, so I assumed the claim was denied. Today I reached out to the adjuster to verify and was told the case was closed and I was 100% liable for “unsafe lane change”. I inquired as to what caused the change from the double fault I was told about to this, and was completely ignored in the adjusters reply as she just stated that she’d resend the letter. The letter is very minimal and doesn’t mention the cause for liability. I am livid that the driver gets to walk away with nothing on her record for her negligence. I understood no matter what I’d be affected, which I didn’t agree with as the wording makes it seem like I hit Vehicle A as I merged to the left lane when Vehicle A made the right turn that ended up hitting me. Is this just a poor insurance company or is the lack of communication common with insurance claims?
