The foregoing are statutory exemptions, special provisions that have been adopted from time to time to meet specific and changing problems. In addition, day in and day out in countless places around the country special permits are issued for the movement of special objects above and beyond the dimensions or weights as set forth in State laws and the AASHO Code. Such practical and flexible handling of the problem would be precluded by rigid application of the standards in the code. For all of the reasons I have outlined, we believe it is unsound and impractical to attempt to apply a single set of rigid standards to apply to all parts of the country and under all conditions, and that the problem can best be handled by the States themselves. If there is any need for Federal intervention it is still to be found in the fact that some States continue to apply restrictions that are unduly restrictive and unnecessarily burden interstate commerce.
