Before you investigate any incident while patrolling in a vehicle, you should _____

When preparing to investigate an incident while patrolling in a vehicle, it is essential to inform someone by radio and leave written notes. This approach enhances safety and accountability.

Informing someone by radio ensures that your status and location are known to others, which is crucial for your safety and overall coordination. It allows for backup to be called if necessary and provides a communication line to report any emergencies or developments during your investigation.

Leaving written notes serves as a record of the incident, providing important details that can be referenced later. Documentation helps in maintaining an accurate account of events and can be vital for any subsequent follow-up or legal processes.

Both actions together promote thoroughness and safety during the investigation, ensuring that your actions are communicated and documented appropriately, which can be critical if further actions or investigations are required later.
