Limited-access road

Expressways in India make up more than 5,579 km (3,467 mi) of the Indian National Highway System[7] on which they are the highest class of road.

The National Highways Development Project is underway to add an additional 18,637 km (11,580 mi) of expressways to the network by the year 2023.

While still functioning as high-speed roads, semi-expressways may still have at-grade intersections with traffic lights, and speed limits are not uniform.

Motorways in South Korea (자동차 전용 도로, jadongcha jeonyong doro, literally 'motor vehicle-only road') include various grades of highways other than expressways.

Contrary to the expressway in South Korea, the status of motorway is a measure of traffic control rather than a class of road.

Schnellstraßen are very similar to Austrian Autobahnen (freeways/motorways); the chief difference is that they are more cheaply built with smaller curve radius, often undivided and have fewer bridges and tunnels.

In Denmark, a 'motortrafikvej' (Danish for "motor traffic road") is a high-speed highway with a speed limit between 80–90 km/h (50–56 mph).

The access is limited to motor vehicles faster than 50 km/h, thus excluding pedestrian, bicycle, moped or tractor traffic; furthermore, towing is not allowed.

Type C highway (or strada extraurbana secondaria), a single carriageway with at least one lane for each direction and shoulders.

In absence of specific regulation signs, a type-C road is accessible by all vehicles and pedestrians, even if it has separate carriageways and no cross-traffic.

In Norway, a motortrafikkvei (Norwegian for "motor traffic road"), formerly called motorvei klasse B ("class-B motorway") is a high-speed highway with a speed limit of up to 90 km/h.

Droga ekspresowa (plural: drogi ekspresowe) refers to a type of road in the Polish highway network, with slightly lower technical parameters than the autostrada (motorway), and serving major international and inter-regional purposes.

The legal term via reservada a automóveis e motociclos (reserved way for automobiles and motorcycles) is used to designate a non-motorway road where motorway rules apply (except the speed limit which is lower).

The dual carriageway vias rápidas can be classified and signalized as reserved ways for automobiles and motorcycles, cases in which general motorway rules apply, except speed limited which is never above 100 km/h.

In dual carriageway vias rápidas not signalized as reserved ways, normal road rules apply, including speed limit which is never above 90 km/h.

Single carriageway vias rápidas cannot be classified and signalized as reserved ways and so normal road rules always apply there.

"Roads for cars" are different from motorways by the fact that they don't have to be dual-carriageway, at-grade traffic light intersections are permitted, and the speed limit is still 90 km/h.

Many roads such as the A1, the A14, the A19 and the A42 are built to a high quality, in many places they are only intersected by grade-separated junctions, have full barriers at both the road side and the central reservations and in some cases three or more lanes of traffic, however they are not subjected to motorway restrictions as they are typically built to a lower standard, or have existing rights of way for non motorised vehicles.

An example of this is the Gardiner Expressway through western and downtown Toronto, and once it turns into a 6-lane arterial road (Lake Shore Boulevard) east of the Don River, there is a sign warning of the end of the freeway.

The Veterans Memorial Parkway in London, Ontario, has intersections instead of interchanges, and thus is considered an expressway and not a freeway.

While Allen Road and Highway 400 were originally full freeways, their extensions (for Allen Road to meet Sheppard Avenue and Dufferine Street, and the 400 South Extension which became Black Creek Drive and handed over to Metro Toronto upon completion) were built as expressways with at-grade intersections.

In most of Western Canada, an expressway is a high-speed arterial road along the lines of the California definition, while a freeway is fully controlled access with no at-grade intersections.

This distinction was first developed in 1949 by the Special Committee on Nomenclature of what is now the American Association of State Highway and Transportation Officials (AASHTO).

The same distinction has also been codified into the statutory law of eight states: California,[29] Minnesota,[30] Mississippi,[31] Missouri,[32] Nebraska,[33] North Dakota,[34] Ohio,[35] and Wisconsin.

Ohio's statute is similar, but instead of the vague word "generally", it imposes a requirement that 50% of an expressway's intersections must be grade-separated for the term to apply.

However, many states around the Great Lakes region and along the Eastern Seaboard have refused to conform their terminology to the federal definition.

Ultimately, it is the federal definition that defines a road's classification whether it is an expressway or freeway no matter the preferred term.

No state, for instance, could have what is technically an expressway given Interstate status just because semantically they use the term interchangeably with freeway.

Although the county originally planned to upgrade the expressways into full-fledged freeways, such a project became politically infeasible after the rise of the tax revolt movement in the mid-1970s, which began with California Proposition 13 in 1978.

In Brazil, an expressway is known as Via Expressa and its function is to connect the most important streets and avenues of certain cities with their adjacent highways.
