All freeways are highways, but not every highway is a freeway. A freeway is a "controlled-access" highway also known as an express highway that's designed exclusively for high-speed vehicular traffic. Traffic flow on a freeway is unhindered because there are no traffic signals, intersections, or at-grade crossings with other roads, railways, or pedestrian paths. The main difference between freeways and multilane highways is that in the case of freeways, these roads are separated from the rest of the traffic and can only be accessed by ramps. These ramps slip roads allow for speed changes between the freeway and arterial thoroughfares and collector roads. Opposing directions of traffic on a freeway are physically separated by a central reservation median , such as a strip of grass or boulders, or by a traffic barrier.

They are free of any at-grade crossings with other roads, railways, or pedestrian paths, which are instead carried by overpasses and underpasses.
