I'm doing my second stop of the day. A NDA signiture required delivery at a residential area. I got there and parked the package car at the curb. Flashers on and mirror folded. I walk out with the package. See nobody. No cars starting up or running. I cross the street and rang the door bell a couple times. Waited for about a minute. No answer. Info notice NI1. Then I heard a loud bang. Turn around and just saw my truck sitting there thinking something heavy fell off the shelf. As I service cross the box and go around the truck, that's when I saw an old lady outside her car looking at the damages. She somehow made contact with the front bumper of the truck when she drove out of her driveway in reverse. The package car wasn't damage. But her Prius will require a new bumper since it struck right side. She did not argue or complain to me. She appears to feel guilty about it yet was in a rush to get to work. I called the center immediately and talk to my manager. He told me to give her his number and for her to call him which I did and for me to continue my route. Here where things get messy. The lady and I both took pictures of the accident and exchange ID's, but both of us forgot to exchange phone numbers. Later in the evening my manager calls me and stated that she hasn't call him back. He tells me to give him the address where the incident occurred so he can go and see if she is there. I get a call again from him asking what the color the car was and he said he'll take care of it going forward. Today I have the day off. So tomorrow I will hopefully find out if I'm DQ. This type of DQ would really suck because I did nothing wrong but know how UPS treats every accident like it's your fault. Not getting her number is my biggest up. If the lady doesn't call him this thing could drag on. My manager said that he wants to talk to her and ask her how she wants to proceed going forward.
