The road sign for a 30 km/h zone in Austria The road sign for a 20 mph zone in the UK. 30 km/h zones (30 kilometres per hour zones) and the similar 20 mph zones (20 miles per hour zones) are forms of speed management used across areas of urban roads in some jurisdictions. The nominal maximum speed limits in these zones are 30 kilometres per ...
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 ...
A speed limiter requirement for mopeds was introduced in 1977, with the speed cap being progressively redefined from 35 mph (56 km/h), to 30 mph (48 km/h), back up to 31 mph (50 km/h) and finally to 28 mph (45 km/h) in the late 2000s. [n 1] The 70 mph (113 km/h) speed limit was made permanent in 1978. [n 8]
[2] [3] [4] There is no statutory speed limit for grade-separated freeways; however the typical speed limit in most provinces is 100 km/h (62 mph) or 110 km/h (68 mph). Statutory speed limits for school zones tend to be 30 or 40 km/h (19 or 25 mph) in urban areas and 50 km/h (31 mph) in rural areas. [ 5 ]
SI, and hence the use of "km/h" (or "km h −1 " or "km·h −1 ") has now been adopted around the world in many areas related to health and safety [36] and in metrology [37] in addition to the SI unit metres per second ("m/s", "m s −1 " or "m·s −1 "). SI is also the preferred system of measure in academia and in education.
The legal definition of a moped in the United Kingdom was revised in 1977 to include a maximum design speed of 30 mph (48 km/h). This was further revised to 50 km/h (31 mph) in the 1990s, then 45 km/h (28 mph) in the late 2000s to fall in line with unified European Union licensing regulations.
As older vehicle construction regulations allowed a speedometer accuracy of +/- 10%, in the United Kingdom ACPO guidelines recommend a tolerance level of the speed limit "×10% +2 mph" (e.g., a maximum tolerance in a 30 mph (50 km/h) zone of 30 + (30 × 10% = 3) + 2 = 35 mph).
