NSL sign on a single-track road implying a speed limit of 60 mph (97 km/h) or 50 mph (80 km/h) depending on vehicle type. Default maximum speed limits apply to all roads where no specific lower numeric speed limit is already in force. The default speed limit is known as the national speed limit (NSL). The NSLs vary by road type and for vehicle ...
Highest-posted speed limits around the world. Kilometres per hour are on the left and miles per hour on the right.* A speed limit is the limit of speed allowed by law for road vehicles, usually the maximum speed allowed. Occasionally, there is a minimum speed limit. [1] Advisory speed limits also exist, which are recommended but not mandatory ...
UK speed limits apply only to motor vehicles and are shown in mph. [20] With a few exceptions, they are in multiples of 10, ranging from 20 miles per hour (32 km/h) to 70 miles per hour (113 km/h). Unless a lower speed limit is posted on a road, the national speed limit applies, which varies between class of vehicles and the type of road.
All main countries/regions, except for the United States and the United Kingdom, use the metric system. Some mark this fact by using units on various signs. Note that some smaller English-speaking countries in the Caribbean also use miles per hour. Advisory speed limit signs in most countries list units, although New Zealand does not.
The United Kingdom uses mostly imperial units on road signs for distance measurements and speed limits. [6] Vehicle weight limits are signed only in metric (TSRGD 1981) but older signs with height, width and length restrictions may show metric units in addition to imperial. For distances only miles and yards are used.
Research in 1998 showed that the reduction of some 30 mph (48 km/h) United Kingdom speed limits to 20 mph (32 km/h) had achieved only a 1 mph (1.6 km/h) drop in speeds and no discernible reduction in accidents; 20 mph (32 km/h) speed limit zones, which use self-enforcing traffic calming, achieved average speed reductions of 10 mph (16 km/h ...
Swedish roads are divided into three classes; motorväg, which is a 4–8 lane motorway with a speed limit of 110–120 km/h (68–75 mph), riksväg, which is a state highway with 2–4 lanes and a speed limit of 70–100 km/h (43–62 mph), and länsväg, which is a "county route" with two lanes and a 70–90 km/h (43–56 mph) speed limit.
Meanwhile, in Ireland, its recent speed limit transition from miles per hour to kilometres per hour didn't take effect until 20 January 2005, although distance road signs had already been labelled in metric since the 1970s. [7] The US territory of Puerto Rico uses a mix – speed limits are in mph but distance signs are marked in km.
