What should be done if an emergency vehicle is involved in a collision?

Answer: B — Complete an incident report and notify authorities

In the event that an emergency vehicle is involved in a collision, the appropriate action is to complete an incident report and notify authorities. This procedure is critical as it ensures that the details of the incident are documented accurately and can be reviewed for accountability and future reference. Notifying the authorities is essential for safety reasons, as they may need to manage traffic in the area and provide assistance. Additionally, completing an incident report helps maintain a record for insurance and potential legal purposes. Ignoring the incident, as indicated in another choice, could lead to serious consequences, especially if there are injuries that may not be immediately apparent. Driving away to avoid delays is highly irresponsible and could result in legal repercussions, as fleeing the scene of an accident is against the law. Contacting media to report the incident is also inappropriate and could compromise privacy and the investigation. Thus, following proper protocol by documenting the incident and alerting the appropriate authorities is crucial for handling the situation appropriately and legally.
