Approval Resources and Governing Bodies Memoranda:

FHWA - AASHTO/FHWA Joint Implementaion Agreement for MASH 1.7.2016

FHWA - Clarification of Roles and Responsibilities in Implementing the AASHTO/FHWA Joint Implementation Agreement on MASH 3.17.2017

FHWA - Will FHWA consider allowing sole sourcing or other procurement exceptions until additional compliant devices are available? If not, how does FHWA plan to deal with a date that arrives before there is enough competition within a product category? FHWA will consider supported requests for the use of proprietary products in accordance with regulations established in 23 CFR 635.411. In many cases, States have assumed this responsibility on behalf of FHWA per their Stewardship and Oversight Agreement with the FHWA Division Office. AASHTO TCRS and FHWA will evaluate and monitor the availability of MASH-compliant devices and revisit the Implementation Agreement as needed. Link to FAQ's on FHWA site - #28 on Page 8
