The AASHTO Manual for Assessing Safety Hardware (MASH) is the latest in a series of documents that provide guidelines on testing and evaluating roadside safety features. The 2016 document represents a comprehensive update to crash-test and evaluation procedures to reflect changes in the vehicle fleet, operating conditions, and roadside safety knowledge and technology.

The TRB National Cooperative Highway Research Program's NCHRP Research Report 1024: Evaluation of Bridge Rail Systems to Confirm AASHTO MASH Compliance presents an evaluation of bridge rail systems to confirm their compliance with MASH.

Supplemental to the report are Appendices A-H.
