The federal size and weight regulations apply to the National Network of interstates because these regulations are designed to maintain safety and efficiency on major highways used for interstate commerce. The National Network includes the interstate system along with certain U.S. highways that are deemed essential for commercial vehicles. By enforcing specific size and weight limits on these routes, the federal government helps to reduce the risk of road damage, improves safety conditions for all road users, and facilitates smoother transportation of goods across state lines. The design of these regulations reflects the critical role that interstate transportation plays in the economy and the necessity to standardize rules across different jurisdictions to prevent confusion and ensure compliance. In contrast, private motor vehicles and local urban roads are typically subject to different regulations determined by state and local authorities, which might not align with federal standards. International freight routes are also governed by various international and country-specific regulations, which may not fall under the same federal guidelines.
