Which term describes a highway with full control of access?

A highway with full control of access is referred to as a freeway. This designation means that the highway is designed to facilitate high-speed vehicular traffic, where access points are limited to interchanges rather than at-grade intersections or driveways. Freeways are characterized by features such as multiple lanes of traffic in each direction, a median separating opposing traffic, and controlled entry and exit points, which enhances safety and reduces congestion.

The term "expressway" is often used in similar contexts but may allow some at-grade intersections or access points, which differentiates it from a freeway. Similarly, local roads provide access directly to residential areas and businesses, without the controlled entry points found on freeways. The term "restricted access highway" may imply limited access but can encompass both expressways and freeways; however, the specific term for highways with full access control is the freeway. This distinction helps clarify how various types of roads facilitate vehicle traffic in different contexts.
