What significance does the traffic collision report have?

The traffic collision report is not admissible as evidence at trial. However, the report is very persuasive during the claims process and early on in the litigation process because insurance companies give great deference to the report, despite the fact that the officer most likely did not observe the accident firsthand. Furthermore, if the officer who wrote the traffic collision report is called to testify at trial, he or she will most likely review the report in order to refresh their memory, so the content of the report can influence how they eventually testify.
