After being involved in an accident, how long do I have to submit an operator's accident report to the police department.

The person operating the vehicle or, in the case where the operator is hospitalized and unable to submit the report, the owner if not the operator must submit the report within 5 days after the accident, M.G.L. Chap. 90, Sec. 26. The accident report form may be obtained at the Pembroke police station or other local police department.
