LPT: If you witness a car crash, stop and give the drivers your contact information. Even if the cause of the accident looks indisputable.

I was an insurance adjuster who dealt specifically with dispute and injury claims. People lie, people don't pay attention, and people have different versions of the truth. There are no cameras, the cop didn't witness the accident, and the damage doesn't prove anything. Just 1 statement from 1 random witness who takes the time to pull over, see if everyone is ok, and provide their information, is the difference between truth prevailing and frustrations for everyone. If you were a witness for an accident, thank you for helping.
