Road speed limits in the United Kingdom are used to define the maximum legal speed (which may be variable) for vehicles using public roads in the UK. Speed limits are one of the measures available to attempt to control traffic speeds, reduce negative environmental effects of traffic, increase fuel use efficiency and satisfy local community wishes.
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.
Enforcement is used to increase compliance with speed limits. One of the main motivations for enforcement is to reduce road casualties, particularly at accident blackspots. [2] For 2008, "exceeding the speed limit" was reported as one of the contributory factors in 5% of all casualty collisions (14% of fatal collisions resulting in 15% of all ...
British roads are limited for most vehicles by the National Speed Limit.Road signs in the UK use imperial units, so speed limits are posted in miles per hour.Speed limits are the maximum speed at which certain drivers may legally drive on a road rather than a defined appropriate speed, and in some cases the nature of a road may dictate that one should drive significantly more slowly than the ...
Speed limits then propagated across the United States; by 1930 all but 12 states had established numerical limits. [12] In 1903, in the UK, the national speed limit was raised to 20 mph (32 km/h); however, as this was difficult to enforce due to the lack of speedometers, the 1930 "Road Traffic Act" abolished speed limits entirely. In 1934, a ...
In West Virginia school zones have a statutory speed limit of 15 mph (24 km/h), except for roads with a speed limit of 55 mph (89 km/h) or higher, which have an advisory speed of 35 mph (56 km/h) in school zones when children are present. A school zone includes 200 ft (60 m) adjacent to the school (or school road) in both directions.

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 speeds. Speed limits are commonly set by the legislative bodies of national or local governments.
