Interim Approvals allow the FHWA to grant authority to State and local highway agencies to use on an interim basis "proven successful" and "proven safe" new traffic control devices or applications that are not specifically described in the MUTCD. Such approvals are based on the results of successful experimentation, studies, or research, and an intention to place the new or revised device into a future notice of proposed amendments to the MUTCD. This process allows the traveling public and/or operating agencies to more quickly realize the safety and operational benefits associated with such devices or applications.
The following list shows the State and local highway agencies that have been granted an Interim Approval.
Please note that Interim Approvals IA-1, IA-2, IA-4R, IA-8, IA-9, and IA-10 have been terminated because the devices or applications involved have been incorporated into the 2009 MUTCD.
(*) Denotes that all local highway agencies in that State are included in the Interim Approval.
