6.0 FHWA's Actions based on House Report 115-237

On March 28, 2018, the FHWA issued a memorandum reinstating the previously terminated Interim Approval 5 allowing the optional use of the Clearview letter style for Positive Contrast Legends on Guide signs. This reinstatement allowed jurisdictions that previously had approval to use IA-5 prior to the January 25, 2016 termination to immediately start reusing Clearview per the provisions of the Interim Approval and the previously issued Design and Use Policy for Clearview Alphabet.25 Per Section 1A.10 of the MUTCD, States and jurisdictions seeking permission to use the provisions of an Interim Approval for the first time must submit a written request to the FHWA and receive approval prior to use. The FHWA also posted responses to frequently asked questions related to the reinstatement and use of Interim Approval 5 on the MUTCD Web site.26
