In the US, “freeway” typically refers to a toll-free, high-speed road with limited access, while “highway” is a broader term for any major public road.

Freeway Vs. Highway

A freeway, as defined by the Federal Highway Administration (FHWA), is a divided highway with access-controlled ramps and full control of vehicular traffic movements. Freeways are designed to facilitate faster and uninterrupted travel, typically allowing for higher speed limits. They are often characterized by their multiple lanes, overpasses and underpasses, and limited points of entry and exit.

A highway is a general term used to describe a public road that connects various destinations. Highways can encompass a wide range of road types, including two-lane roads, multi-lane roads, and even freeways. Unlike freeways, highways may have traffic lights, intersections, and driveways, making them not fully access-controlled.
