MMUCC Evaluation Survey A

Introduction

The National Highway Traffic Safety Administration (NHTSA) is seeking feedback from law enforcement officers on the feasibility of collecting the crash data described in the Model Minimum Uniform Crash Criteria (MMUCC) Guideline, fifth edition (DOT HS 812 433, July 2017). As a law enforcement officer who responds to crashes and writes crash reports, your participation is important to help NHTSA identify crash data elements and concepts that can be accurately collected and others that are flawed and require revision or elimination. All responses are anonymous and will be analyzed in the aggregate. The information you provide will inform the content of the next edition of MMUCC. We estimate that it will take you approximately 60 minutes to complete the survey. NHTSA will publish a summary of this research in an appendix to the next edition of MMUCC in 2024.


This collection of information is voluntary and will be used to identify problematic crash data elements, and concepts in MMUCC. A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with, a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB Control Number. The OMB Control Number for this information collection is XXXXX. Public reporting for this collection of information is estimated to be approximately 60 minutes per response, including the time for reviewing instructions, and completing and reviewing the collection of information. All responses to this collection of information are voluntary. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to: Information Collection Clearance Officer, National Highway Traffic Safety Administration, 1200 New Jersey Ave, S.E., Washington, DC, 20590.
