When documenting injury severity on the CR-3 form, which category includes injuries that necessitate immediate medical attention?

The category that includes injuries necessitating immediate medical attention is "Severe Injury." This classification is meant to represent injuries that are critical or life-threatening, requiring prompt medical intervention to prevent further harm or address serious health issues. Such injuries may include significant trauma, severe lacerations, head injuries with unconsciousness, or any condition that poses an immediate risk to life or health.

In this context, it’s important to differentiate "Severe Injury" from "Serious Injury," which typically refers to injuries that are serious but may not require immediate medical attention or could stabilize over time. "Minor Injury" would indicate less critical injuries that may not need urgent care, and "Non-injury" applies to situations where no injury has occurred at all. Understanding these distinctions is crucial for accurately documenting incidents in accordance with traffic code practices.
