The person who caused the accident is obviously going to waive the traffic collision report because that means the officer is not going to investigate how it happened; and therefore, also will not state an opinion as to who caused the accident. The party who was hit by the at-fault driver feels that they don’t want to burden the officer by requesting the traffic collision report, and the other party seems to feel bad for causing the accident, so they assume the at-fault driver is going to accept full responsibility for the accident.
All too often, when there is no traffic collision report, the at-fault driver’s auto insurance carrier will deny the claim filed against their insured. Since there is no traffic collision report and no written investigation determining who was at fault, the at-fault party and their insurance company can say whatever they want regarding how the accident happened; and often do take such liberties. Get the traffic collision report. It’s important.
