Q and A released for issues raised since May 2018

New information is now available that clarifies issues related to implementing the 2016 edition of the Manual for Assessing Safety Hardware (MASH).

The American Association of State Highway and Transportation Officials (AASHTO) publishes MASH and issued the latest updates in a Question-and-Answer format. The latest information is the result of work produced by a joint technical working group of people from state departments of transportation (DOTs), the Federal Highway Administration (FHWA) and accredited crash testing labs, according to a statement included in the release.

The new Q&A is the result of information compiled since May 2018 to clarify and implement the 2016 edition of MASH.

The information resulted from questions generated by the roadway safety industry about the testing of roadway safety hardware under MASH, according to the AASHTO announcement. The Q & A is intended to provide additional help to manufacturers, crash test labs and DOTs in developing roadway safety equipment.
