Which statement about using the 5th edition of MMUCC for crash data reporting is true?

• A. Because the MMUCC sets a minimum threshold for crash data collection, many significant crash data elements can be missed.
• B. MMUCC requires all crashes to be reported.
• C. MMUCC eliminates need for local data collection.
• D. MMUCC has no data elements beyond basic fields.

Answer: (A)

MMUCC 5th edition establishes a baseline set of data elements that should be collected across crashes to promote consistency and comparability. This baseline acts as a minimum, not the full, all-encompassing dataset. Because of that, if a jurisdiction sticks to only the minimum elements, many additional, potentially significant crash data elements—such as detailed contributing factors, context, or advanced vehicle and environment data—may not be captured. That’s why this statement is the best answer: MMUCC provides a starting point for data collection, but it does not by itself guarantee a complete picture of every crash.

The other options aren’t correct because MMUCC does not require reporting of every crash across all jurisdictions, it does not eliminate the need for local data collection, and it includes more than just basic fields—there are many elements beyond the core minimum that states can and do collect to support deeper analysis.
