You can request a crash report from the Registry of Motor Vehicles. However, the RMV will charge a $20 search fee for each report. If the Holyoke Police responded to your accident, you can buy your report online through Crashdocs or BuyCrash, or you can get your report in person at the police station at 138 Appleton St.
Alternatively, you can just fill out the form on this page to get your accident report. Or, if you hire a Holyoke car accident lawyer, they can handle the request for the report on your behalf and review it with you in a free consultation.
