What is required of law enforcement officers after a traffic crash results in injury or significant property damage?

After a traffic crash that results in injury or significant property damage, law enforcement officers are required to forward a written crash report to the Department of Motor Vehicles (DMV). This report is essential for several reasons: it helps in documenting the details of the incident, which can be crucial for investigations, insurance claims, and subsequent legal proceedings. The information in the report assists the DMV in tracking crash statistics, ensuring that they can spot patterns in traffic incidents that may necessitate changes in public safety measures or traffic laws.

The other options describe actions that are not mandated or are either not comprehensive or relevant to the responsibilities of law enforcement in this context. For example, while issuing tickets may happen if violations are observed, it is not a requirement in every case. Documenting an incident log is part of the officer's duties but does not fulfill the legal obligation of reporting to the DMV. Contacting insurance companies is generally the responsibility of the involved parties, rather than law enforcement. Thus, forwarding a written crash report to the DMV stands as the clear requirement following such incidents, ensuring a systematic approach to road safety and accountability.
