National Network (or National Truck Network ) is an approved and interstate state highway network for commercial truckers in the United States. The Surface Transportation Assistance Act of 1982 certifies the formation of a national highway network intended for use by large trucks. On this highway, Federal width and long limits apply. The National Network (NN) covers almost all Interstate Highway Systems and other specified non-interstate highways. The network comprises more than 200,000 miles of highway.

Definitions

National Network Network Criteria listed in the appendix of this section are available for use by commercial motor vehicles of the dimensions and configurations described in Ã, §658.13 and Ã,§658.15. For countries with a detailed list of each route in the appendix, routes have been established on the basis of their general compliance with the following criteria.

• This route is a typical geometrical component of the Federal-Aid Primary System, which serves to connect the major cities and intensive parts of America.
• The route is a high volume route that is widely used by large vehicles for interstate commerce.
• The route has no restrictions impeding use by conventional combination vehicles.
• This route has sufficient geometry to support safe operations, taking into account visibility, severity and duration, sidewalk width, horizontal curvature, shoulder width, bridge clearance and load limit, traffic volume and vehicle mix, and geometry intersection.
• This route consists of paths designed to have a width of 12 feet or more or consistent with road safety.
• The route does not have any unusual characteristics that cause current or anticipated safety issues.

The most recent National Network is defined by the Intermodal Surface Transportation Efficiency Act of 1991. Information on this route is taken from Ã, §658 Appendix A. Some states such as Indiana, Arkansas and Ohio allow truck traffic on all roads numbers or the US highway. Other countries, such as New York and California, have a collection of special highways recommended for trucks. The law allows "reasonable access" to and from NN for terminals, shipments, truck stops, repairs, and other reasons. NN is recommended for via truck traffic (eg traffic passing through the area), and trucks are allowed to operate on restricted trucked roads if they do not have other means of access to their destination.
