Such highways in southern Ontario, southern Quebec, and parts of Atlantic Canada usually feature full controlled-access with interchanges where robust federal and provincial funding has made such freeways possible. However, due to a lack of funding elsewhere, partial controlled-access "expressways" and limited-mobility divided arterial roads are more common in the western provinces where there are no specially numbered systems of freeways.

Almost all of the network is 6 lanes (3 in each direction) wide and illuminated. Some parts converted from uncontrolled access dual carriageways are 4 lanes (2 in each direction) wide. The motorway sign in Turkey is green and uses Highway Gothic typeface.

Nowadays they are similar to HQDCs, but minor at grade exits—generally left turn only—are allowed and the design speed (by Irish standards) is only 100 km/h. Median crossings and roundabouts are no longer generally found on these schemes. An example of a standard dual carriageway scheme, opened in 2006, is the

Access limitations and drive behaviour on type-B roads are the same as the motorways (no pedestrians, bicycles and other slow vehicles), as well as the signage (except for the background color, that is blue instead of green). Speed limits on type-B roads are up to 110 km/h (70 mph). Type-B roads are always toll-free.
1018:(type B). This means that a dual carriageway that may not be classified as type-B road, since it does not meet such quality standards, belongs to this category. For type-C roads, there are neither special signage nor access restrictions, unless a specific sign is placed. The speed limit is 90 km/h (55 mph), on both single and dual carriageways.

and road tunnels (or 'underpasses') can be built to minimize the use of traffic lights; for example, at the
Holland Road-Farrer Road-Queensway junction there are three levels of roads. Before the 1980s, roundabouts were popular, but since then many have been changed to traffic-light controlled junctions.

The majority of dual carriageway roads now have barriers. Some are heavy concrete obstructions which can bounce a vehicle back into the path of other traffic; others are made from steel ropes mounted on moderately weak posts, where the rope cuts into the vehicle body to slow the vehicle while keeping

In Canada, the term "divided highway" is used for this type of road, and the segment between the roadways is referred to as a "median". There may be gaps in the median strip of a partially controlled-access road to allow turning and crossing. More informally, a divided highway may be referred to as

Dual carriageways of this class differ from motorways in a number of ways. The hard shoulder is demarcated with a dashed yellow line (as opposed to an unbroken yellow line on motorways). The standard speed limit of 100 km/h (62 mph) for national routes usually applies (by default the limit

Frequently in the U.S. the two carriageways are separated by some distance (wide medians with small forests or even hills in them), but drivers can always tell whether the roadway is two-way or one-way—and, if one-way, the direction in which the traffic flows—by looking at the striping coloration.

Traffic lights and junctions are permitted at grade on dual carriageways. For older sections of dual carriageway, this has resulted in fewer flyover junctions. Newer dual carriageway sections are usually near motorway standard, with grade-separated junctions, but may not be designated as motorways

A dual carriageway in a built up area will have a statutory speed limit of 30 mph (48 km/h) unless otherwise sign-posted. It is common for such urban dual carriageways to have an increased speed limit of 40 mph (64 km/h). A road deemed to be in a built up area is indicated by

Until 2005, many motorways and dual carriageways in

Turning right (that is, across the line of traffic heading in the opposite direction) is usually permitted only at specific locations. Often the driver will be required to turn left (away from the dual carriageway) in order to loop around to an access road that permits crossing the major road.
