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.Advisory speed limit also exist. Speed limits are commonly set by the legislative bodies of national or local governments.
The following tables show various jurisdictions' default speed limits (where applicable) that apply to different types of vehicles travelling on three different types of road. Actual speed limits may range beyond these values. Speeds are listed in kilometres per hour unless otherwise stated. The enforcement tolerance is specified in km/h or percentage above the stated limit. For the United Kingdom and the United States, the speed limit is listed in miles per hour.
Germany is the only country where some motorways do not have a maximum speed limit. The 130 km/h is sign-posted as a general advisory speed limit for motorways in the entry of the country. Due to those Autobahns, Germany is considered a country without a general speed limit on its highways. The Isle of Man is the only jurisdiction without a general speed limit on rural two-lane roads.
Numerous countries have a different general speed limit for urban roads than on remaining roads. Such differences exist since the beginning of the 20th century, in countries such as United Kingdom and France. This concept is formally defined as road within built-up area in various regulations, including Vienna convention, even if UK has re-branded them as street lighted or restricted area. More informally they are known as urban road. In 2017, most of all IRTAD countries have a default speed limit in urban roads of 50 km/h, with various lower speeds, for instance, in the Netherlands, 70% of the urban roads are limited to 30 km/h.
Different speed limits exist for Heavy Good Vehicles (HGV) but the limit for HGV is country dependent: While most Eurasian and Latino-American States might use the Vienna convention 3.5 tonnes limit, other countries in North America, China, India, Australia or Ireland might use different weight limits.
Note: Speeds quoted ( ) are in miles.

|50 for un-signed residential roads and some built up areas. 60 for major roads. 70 and 80 km/h limits are occasionally used for major arterial roads which have more than one lane in each direction.||Generally 80–110 km/h depending on the conditions for that road. In remote parts of Australia, such as outback Northern Territory, Queensland, South Australia and Western Australia, 110–130 km/h speed limits are used. |
For learner drivers and probationary drivers in certain states, speed limits between 80 km/h and 100 km/h apply as a maximum along all roads where the posted limit is equal or higher.

Speed limits are used in most countries to set the legal maximum speed at which vehicles may travel on a given stretch of road. Speed limits are generally indicated on a traffic sign reflecting the maximum permitted expressed as kilometres per hour (km/h) and/or miles per hour (mph). Speed limits are commonly set by the legislative bodies of national or provincial governments and enforced by national or regional police and judicial authorities. Speed limits may also be variable, or in some places nonexistent, such as on most of the Autobahn in Germany.
A dual carriageway or divided highway is a class of highway with carriageways for traffic travelling in opposite directions separated by a central reservation. Roads with two or more carriageways which are designed to higher standards with controlled access are generally classed as motorways, freeways, etc., rather than dual carriageways.
A limited-access road, known by various terms worldwide, including limited-access highway, dual-carriageway, expressway, and partial controlled access highway, is a highway or arterial road for high-speed traffic which has many or most characteristics of a controlled-access highway, including limited or no access to adjacent property, some degree of separation of opposing traffic flow, use of grade separated interchanges to some extent, prohibition of some modes of transport such as bicycles or horses, and very few or no intersecting cross-streets or level crossings. The degree of isolation from local traffic allowed varies between countries and regions. The precise definition of these terms varies by jurisdiction.
A controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway, motorway and expressway. Other similar terms include throughway and parkway. Some of these may be limited-access highways, although this term can also refer to a class of highway with somewhat less isolation from other traffic.
Road speed limits in Ireland apply on all public roads in the state. These are signposted and legislated for in kilometres per hour. Speed limits are demarcated by regulatory road signs. These consist of white circular signs with a red outline. Speed limits are marked in black with "km/h" below the speed limit. Smaller "repeater" speed limit signs are used along stretches of road where there is no change in speed limit, in order to remind motorists currently on the road and to inform traffic merging from junctions that a certain speed limit applies.
A single carriageway or undivided highway is a road with one, two or more lanes arranged within a single carriageway with no central reservation to separate opposing flows of traffic.
Driving in the United Kingdom is governed by various legal powers and in some cases is subject to the passing of a driving test. The government produces a Highway Code that details the requirements for all road users, including drivers. Unlike most other countries in the world, UK traffic drives on the left.
Road signs in Thailand are standardized road signs similar to those used in other nations but with certain differences. Until the early 1980s, Thailand closely followed US, Australian, and Japanese practices in road sign design, with diamond-shaped warning signs and circular restrictive signs to regulate traffic. Signs usually use the FHWA Series fonts typeface also used in the United States.
Road signs in South Korea are regulated by the Korean Road Traffic Authority.
Road speed limits in the United Kingdom are used to define the maximum legal speed 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. The speed limit in each location is indicated on a nearby traffic sign or by the presence of street lighting. Signs show speed limits in miles per hour (mph) or the national speed limit (NSL) sign may be used.
Speed limits in Germany are set by the federal government. All limits are multiples of 10 km/h. There are two default speed limits: 50 km/h (31 mph) inside built-up areas and 100 km/h (62 mph) outside built-up areas. While parts of the autobahns and many other freeway-style highways have posted limits up to 130 km/h (81 mph) based on accident experience, congestion and other factors, many rural sections have no general speed limit. The German Highway Code (Straßenverkehrsordnung) section on speed begins with the requirement which may be rendered in English:
Any person driving a vehicle may only drive so fast that the car is under control. Speeds must be adapted to the road, traffic, visibility and weather conditions as well as the personal skills and characteristics of the vehicle and load.
Speed limits in the Czech Republic vary depending on the type of road, and whether the road is within a settlement or not. The top speed limit is 130 km/h (81 mph) for motorways outside of settlements, whereas on regular roads within a settlement the speed limit is 50 km/h (31 mph). outside of the settlement and other than motorway the speed limit is 90 km/h. Various other special restrictions are applied for certain types and weight categories of vehicle.
Spain has different speed limits for every kind of road and vehicle. Until 1973, there were no speed limits on Spanish motorways, a generic limit of 130 km/h was instated then in order to save fuel during the 1973 energy crisis. It was lowered to 100 km/h to prevent accidents, but it was raised again in 1992, this time to 120 km/h. There have been proposals to raise the speed limit to 130 km/h, but have been rejected so far.
The default speed limits in the Netherlands are 50 km/h (31 mph) inside built-up areas, 80 km/h (50 mph) outside built-up areas, 100 km/h (62 mph) on expressways (autowegen), and, as of March 16, 2020, 100 km/h from 6:00 to 19:00 and 130 km/h from 19:00 to 6:00 on motorways (autosnelwegen). On September 1, 2012, the motorway default speed limit was raised from 120 km/h (75 mph) to 130 km/h (81 mph), but it applies to only 48% of all motorways with the intent of 60% of motorways.
Speed limits in Pakistan are similar to most European countries on newer roads with most highways at 120km/hr, and somewhat higher in the western areas of the country. There are some areas of the country with no enforced speed limit.
General speed limits in New Zealand are set by the New Zealand government. The speed limit in each location is indicated on a nearby traffic sign or by the presence of street lighting. The limits have been posted in kilometres per hour (km/h) since 1974. Before then, when New Zealand used imperial units, maximum speeds were displayed in miles per hour (mph). Today, limits range from 10 km/h (6.2 mph) to 110 km/h (68 mph); in urban areas the default speed limit is 50 km/h (31 mph).
Speed limits in the United States vary depending on jurisdiction. Rural freeway speed limits of 70 to 80 mph are common in the Western United States, while such highways are typically posted at 65 or 70 mph in the Eastern United States. States may also set separate speed limits for trucks and night travel along with minimum speed limits. The highest speed limit in the country is 85 mph (137 km/h), which is posted on a single stretch of tollway in exurban areas outside Austin, Texas. The lowest maximum speed limit in the country is 30 miles per hour (48 km/h) in American Samoa.
Road signs in Georgia are similar to the Russian road sign system that ensure that transport vehicles move safely and orderly, as well as to inform the participants of traffic built-in graphic icons. These icons are governed by the Vienna Convention on Road Traffic and Vienna Convention on Road Signs and Signals.
Road signs in Kyrgyzstan are similar to the Russian road sign system that ensure that transport vehicles move safely and orderly, as well as to inform the participants of traffic built-in graphic icons. These icons are governed by the Vienna Convention on Road Traffic and Vienna Convention on Road Signs and Signals.
Speed limits in Thailand are a set of maximum speeds applicable on any road in Thailand. For small cars that weigh less than 1,200 kg (2,646 lb), the maximum limits within the built-up area and outside are 80 km/h (50 mph) and 90 km/h (56 mph) respectively. The exception applies to motorways, in which small cars can use up to 120 km/h (75 mph). Heavier cars, buses and trailer have more restrictive limits. Despite having the general maximum speed limits, the limits may be altered by a roadside sign.
