Figure 1A-2. Process for Incorporating New Traffic Control Devices into the MUTCD
This figure shows an example of the process for incorporating new traffic control devices into the MUTCD. This process is shown as a flow chart:
- The flow chart begins with a successful experiment (see Figure 1A-1), analytical or laboratory study results and/or non-U.S. experimentation, or a request for change from the jurisdiction or an interested party, each of which may lead to the FHWA review. The FHWA review leads to a determination of whether the new traffic control device should be accepted for Federal rulemaking.
- If the new traffic control device is not accepted for Federal rulemaking, the review determines if further experimentation is required. If not, the jurisdiction restores the experiment site to the original condition. If further experimentation is required, then see Figure 1A-1.
- If the new traffic control device is accepted for Federal rulemaking, the FHWA both considers the device for Interim Approval and prepares a Notice of Proposed Amendment, in parallel processes.
- If the FHWA decides not to grant Interim Approval, the FHWA notifies any interested parties.
- If the FHWA does grant Interim Approval, FHWA issues Interim Approval with technical conditions for use and posts on the MUTCD website. The jurisdictions then apply for and receive Interim Approval and deploy the devices under Interim Approval conditions.
- If the FHWA accepts the new traffic control device for Federal rulemaking, FHWA prepares a Notice of Proposed Amendment and then publishes it in the Federal Register. A docket comment period then begins, and the FHWA reviews any comments. The FHWA then prepares and publishes the Final Rule. State Manuals must be in substantial conformance with the National MUTCD within 2 years as specified in 23 CFR 655.603(a).
- If the Final Rule is different from the Interim Approval, jurisdictions restore sites of Interim Approval to previous conditions and/or comply with the Final Rule. If the Final Rule is not different from the Interim Approval, no other action is required.
