You can request a crash report from the Registry of Motor Vehicles, but note that there is a $20 search fee to request the report from the RMV. If the Chicopee Police investigated your accident, you may also be able to submit a public records request to the police department. There may be an administrative fee.
You can easily get your copy of the report using the form on this page. Or you can simply contact a Chicopee car accident attorney. Your lawyer can request the report on your behalf and review it in a free consultation.
