Which document must be filed by a driver involved in an accident resulting in injury?

A driver involved in an accident that results in injury is required to file an accident report. This document serves multiple purposes, such as documenting the details of the incident, collecting information from involved parties, and providing a record for law enforcement and insurance purposes. It is essential for legal and insurance proceedings, ensuring that the incident is officially recorded.

While filing an insurance claim can be important for recovery of costs related to damages or medical expenses, it is not a mandatory document specifically required following an accident with injuries. Similarly, a traffic citation may be issued if one of the drivers violated traffic laws, but this does not apply to all accident scenarios and is not necessarily filed by the driver involved in the accident. Lastly, a civil lawsuit may be initiated after an accident for claims of negligence or damages but is not a requirement for all drivers involved in an accident. Therefore, the correct choice is the accident report, as it fulfills the legal obligation for reporting an injury-causing accident.
