Final answer:
Accidents that must be reported are those that cause death, injury, or property damage of $2,000 or more.
Step-by-step explanation:
Accidents that need to be reported in writing to local Police, RCMP, or Registry of Motor Vehicles are those accidents that cause death, injury, or property damage of $2,000 or more. This requirement allows for more efficient processing and investigation of serious incidents and supports the legal and insurance proceedings that may follow an accident. In the provided example, with total damage incurred by car accidents amounting to $186,000, certainly, incidents causing such high property damage would need to be reported.
