        (a) Federal-aid highways.
         Federal-aid projects involving the installation of traffic control devices shall follow procedures as established in  23 CFR part 630, subpart A, Federal-Aid Programs Approval and Project Authorization. Simplified and timesaving procedures are to be used to the extent permitted by existing policy.
     
    
        
        (b) Off-system highways.
         Certain federally funded programs are available for installation of traffic control devices on streets and highways that are not on the Federal-aid system. The procedures used in these programs may vary from project to project but, essentially, the guidelines set forth herein should be used.
