Maryland
I got into an accident recently and was wondering if anyone had any advice.
I was backing out of a spot in a parking garage. I had checked behind myself and continued to look backwards. I began to slowly back up, when I heard a beep and as I braked there was a collision. Another car had come around the corner of the parking garage and attempted to speed around my car. My car was already halfway into the aisle. When we got out, the other driver said that she hadnt seen me (but she had beeped??). The damage to my car was minimal on my bumper. The front driver side of her car was a little crunched. The accident occured at around 7 pm in an indoor parking garage and the lights of her car were not on.

We exchanged numbers and license plate numbers, but NOT Insurance info.
How would fault or degree of fault be determined? As of now, the damage to my car is very minimal and I would prefer to not report it to my insurance. She said that she will be in touch with her insurance. Any thoughts or advice?
Thanks.
