My question involves a traffic accident in the State of: Wisconsin
I rear-ended someone, and there was no damage to their car, but I stupidly did not get any of their information (not even their license plate) or take pictures. There were 3 people in the car, two parents and their probably high school or college aged daughter. The parents did not speak English, so I communicated with their daughter. They had absolutely no idea what to do, and not being in many problems like this before, neither did I. I was not thinking clearly and was mad at myself for having hit them. I guess I thought since their car didn't have any damage and I was at fault, I didn't need their information. They have my name and phone number. We did not call police since there was no damage, and I have looked into reporting the accident, however in the state of Wisconsin there must be at least $1000 worth of damage or injury for a report to be made. I wouldn't really have enough info to complete the form anyway.
I am worried that they might damage their car in another incident and then try to blame it on me, or that they will claim something like an injury even though they said they were fine and try to sue me later. We had a similar incident to this a few years back in my family where the person that was hit came back at us 2 years later with claims that there was more damage than there was. Does anyone have any advice on how to move forward/deal with this, or is it just a waiting game?
