What must law enforcement do when investigating a motor vehicle crash?

Law enforcement must interview all participants and witnesses when investigating a motor vehicle crash to gather a comprehensive understanding of the incident. This process is crucial because these interviews provide critical information about what happened leading up to the crash, the conditions at the time, and the actions of those involved. Ensuring that all perspectives are captured helps in establishing the facts of the case, which can be essential for determining liability, identifying any suspects for criminal charges, or providing information necessary for insurance purposes. This thorough approach also helps ensure that any potential violations of traffic laws are appropriately addressed.

Other options do not align with the best practices for investigating a crash. Issuing citations remotely lacks the ability to assess the situation adequately on-site and understand the context of the incident. Ignoring minor violations could overlook important factors that contribute to crashes and run counter to maintaining road safety. Lastly, delaying report completion for a month can hinder timely justice and complicate the accuracy of the details due to fading memories or unavailability of witnesses.
