Slow moving vehicle

Last updated

A slow moving vehicle (or SMV) is a vehicle or caravan of vehicles operated on a street or highway at speeds slower than that of other motorized traffic.

Contents

The term "slow moving vehicle" is generally applied to equipment and vehicles such as farm equipment (including tractors), construction equipment, trucks towing trailers, or any such vehicles which cannot operate above a specified speed. [1]

It does not include vehicles normally known to unlikely be operated at that speed or incapable of reaching that speed, such as bicycles, mopeds and disabled vehicles being towed. [2]

North America

In the United States and Canada an individual vehicle, a vehicle which is being towed, or caravans of vehicles, which are unable to reach a maximum speed of 40 kilometres an hour (25 miles per hour) are required by law to display a special reflective emblem sign at the rear of the vehicle or vehicles, or on the rear vehicle in the caravan. The sign is only allowed to be placed where it is visible from the sides, front or the rear of the vehicle.

The sign appears essentially as the image on the right, as a "cut" triangle consisting of a triangle with the corners cut off in red, as a border surrounding an orange uncut triangle in the center, with the edge separating the orange and red being black or white. The United States Department of Transportation as well as various Canadian provinces have established regulations that dictate the minimum required size of the sign, and grant exemptions for displaying the sign for certain religious groups having an objection to displaying a sign, which are operating horse-drawn carriages or wagons on public highways, provided they use an alternative reflective marking on the rear of the wagon or carriage. Vehicles which are merely crossing a road, such as a tractor going from one field directly to another at a 90 degree angle from the road, are not required to display the sign.

The sign must not be displayed so it is visible to a road from an object which is not a vehicle (like a mailbox, billboard, or structure) and vehicles not on a public road must remove or hide the sign if it can be seen from the road.

In the United States, the sign is typically available from hardware, vehicle supply, and construction supply stores for about US$20.

In the United States, slow-moving Vehicle Emblem Requirements are defined in the 29 CFR 1910 Occupational Safety and Health Administration .145(d)(10) regulation. They are based on American Society of Agricultural Engineers (ASAE) Emblem for Identifying Slow-Moving Vehicles, ASAE R276, 1967, or ASAE S276.2 (ANSI B114.1-1971).

In the British Columbia province of Canada, the device is named a "Slow Moving Vehicle Warning Device". It is standardized as C.S.A. Standard D 198-1967 by the Canadian Standards Association according to the Motor Vehicle Act Regulations. [3]

Europe

In Europe, there is no one single "Slow moving vehicle" concept, but concepts depending on various national or international laws.

Most European countries apply the Vienna Convention on Road Traffic, but this convention on road traffic does not require vehicles not reaching a specific speed to carry a specific mark. Indeed, Vienna convention just defines such as the two red reflex-reflectors for trailers, and prohibits some class of roads or some kind to some moving vehicles not able by design to reach a specific speed defined by domestic legislation, for instance on motorways. [4]

However, numerous European countries also apply Unece regulations. Regulation Unece number 69 address rear marking plates for slow-moving vehicles (by construciton) and their trailers. [5] Those marks have a shape like the north-American one.

Unece regulation

Regulation 69 applies to rear marking plates for vehicles of category M (transport of people), N (transport of good), O (transport of trailer) and T (tractors) and for mobile machinery, which, by construction, cannot move faster than 40 km/h. [6]

The mark in the rear vehicle is a "SMV rear marking plate", a triangular plate with truncated corners with a characteristic pattern faced with retro-reflective and fluorescent material or devices (class 1); or with retro-reflective materials or devices only (class 2). [7]

Regulation 69 enter into force on 15 May 1987 in Netherlands and Belgium. On 19 September 1987 in Denmark.

It applies in the United-Kingdom since 27 April 1990.

It applies in the Germany since 8 October 1993.

It applies in Russia since 8 April 1996.

It applies in the European Union since 24 March 1998, including in France and Italy.

In 2020, the regulation applies in the European Union, its 27 member countries an 19 other Unece countries, that is 46 countries.

National European laws

In Belgium, are classified as slow vehicles (véhicules lents) vehicle which cannot by design reach 40 km/h. [8]

Road train Type of trucking vehicle

A road train, land train or long combination vehicle is a trucking vehicle used to move road freight more efficiently than semi-trailer trucks. It consists of two or more trailers or semi-trailers hauled by a prime mover. Long combination vehicles are combinations of multiple trailers on tractor trucks as compared to standard 5 axle semi trailer-trucks with one trailer.

Brake Mechanical device that inhibits motion

A brake is a mechanical device that inhibits motion by absorbing energy from a moving system. It is used for slowing or stopping a moving vehicle, wheel, axle, or to prevent its motion, most often accomplished by means of friction.

International vehicle registration code Codes used to identify where a vehicle is registered

The country in which a motor vehicle's vehicle registration plate was issued may be indicated by an international licence plate country code, formerly known as an International Registration Letter or International Circulation Mark. It is referred to as the Distinguishing sign of the State of registration in the Geneva Convention on Road Traffic of 1949 and the Vienna Convention on Road Traffic of 1968.

Radar speed gun

A radar speed gun is a device used to measure the speed of moving objects. It is used in law-enforcement to measure the speed of moving vehicles and is often used in professional spectator sport, for things such as the measurement of bowling speeds in cricket, speed of pitched baseballs, and speed of tennis serves.

Lane

In road transport, a lane is part of a carriageway that is designated to be used by a single line of vehicles to control and guide drivers and reduce traffic conflicts. Most public roads (highways) have at least two lanes, one for traffic in each direction, separated by lane markings. On multilane roadways and busier two-lane roads, lanes are designated with road surface markings. Major highways often have two multi-lane roadways separated by a median.

Police car Ground vehicle used by police for transportation during patrols

A police car is a ground vehicle used by police for transportation during patrols and to enable them to respond to incidents and chases. Typical uses of a police car include transporting officers so they can reach the scene of an incident quickly, transporting and temporarily detaining suspects in the back seats, as a location to use their police radio or laptop, or to patrol an area, all while providing a visible deterrent to crime. Some police cars are specially adapted for certain locations or for certain operations. Police cars typically have rooftop flashing lights, a siren, and emblems or markings indicating that the vehicle is a police car. Some police cars may have reinforced bumpers and alley lights, for illuminating darkened alleys.

A vehicle registration plate, also known as a number plate, license plate or licence plate, is a metal or plastic plate or plates attached to a motor vehicle or trailer for official identification purposes. The registration identifier is a numeric or alphanumeric code that uniquely identifies the vehicle within the issuing authority's database. In Europe most countries have adopted a format for number plates that satisfies the requirements in the Vienna Convention on Road Traffic, which states that cross-border vehicles must display a distinguishing code for the country of registration on the rear of the vehicle. This sign may be an oval sticker placed separately from the registration plate, or may be incorporated into the vehicle registration plate. When the distinguishing sign is incorporated into the registration plate, it must also appear on the front registration plate of the vehicle, and may be supplemented with the flag or emblem of the national state, or the emblem of the regional economic integration organisation to which the country belongs. An example of such format is the common EU format, with the EU flag above the country code issued in EU member states.

Vienna Convention on Road Traffic International treaty

The Convention on Road Traffic, commonly known as the Vienna Convention on Road Traffic, is an international treaty designed to facilitate international road traffic and to increase road safety by establishing standard traffic rules among the contracting parties. The convention was agreed upon at the United Nations Economic and Social Council's Conference on Road Traffic and concluded in Vienna on 8 November 1968. It came into force on 21 May 1977. This conference also produced the Convention on Road Signs and Signals. The Convention had amendments on 3 September 1993 and 28 March 2006. There is a European Agreement supplementing the Convention on Road Traffic (1968), which was concluded in Geneva, on 1 May 1971.

Automotive lighting Lighting system of a motor vehicle

The lighting system of a motor vehicle consists of lighting and signalling devices mounted or integrated to the front, rear, sides, and in some cases the top of a motor vehicle. This lights the roadway for the driver and increases the visibility of the vehicle, allowing other drivers and pedestrians to see a vehicle's presence, position, size, direction of travel, and the driver's intentions regarding direction and speed of travel. Emergency vehicles usually carry distinctive lighting equipment to warn drivers and indicate priority of movement in traffic.

Road signs in the United Kingdom Overview of road signs in the United Kingdom

Road signs in the United Kingdom and in its associated Crown dependencies and overseas territories conform broadly to European design norms, though a number of signs are unique: direction signs omit European route numbers and road signs generally use the Imperial System of units, unlike the rest of Europe.

Emergency vehicle lighting

Emergency vehicle lighting is one or more visual warning lights fitted to a vehicle for use when the driver wishes to convey to other road users the urgency of their journey, to provide additional warning of a hazard when stationary, or in the case of law enforcement as a means of signalling another driver to stop for interaction with an officer. These lights may be dedicated emergency lights, such as a beacon or a light bar, or may be modified stock lighting, such as a wig-wag or hide-away light, and are additional to any standard lighting on the car such as hazard lights. Often, they are used along with a siren in order to increase their effectiveness.

Safety reflector

A safety reflector is a retroreflector intended for pedestrians, runners, motorized and non-motorized vehicles. A safety reflector is similar to reflective stripes that can be found on safety vests and clothing worn by road workers and rescue workers. They are sometimes erroneously called luminous badges or luminous tags, but this is incorrect as they do not themselves produce light, but only reflect it.

World Forum for Harmonization of Vehicle Regulations Working party

The World Forum for Harmonization of Vehicle Regulations is a working party (WP.29) of the Sustainable Transport Division of the United Nations Economic Commission for Europe (UNECE). Its responsibility is to manage the multilateral Agreements signed in 1958, 1997 and 1998 concerning the technical prescriptions for the construction, approval of wheeled vehicles as well as their Periodic Technical Inspection and, to operate within the framework of these three Agreements to develop and amend UN Regulations, UN Global Technical Regulations and UN Rules, kind of vehicle regulation.

Road signs in Sweden are regulated in Vägmärkesförordningen, VMF (2007:90), and are to be placed 2 metres from the road with the sign 1.6 m from the base for motorized roads. Except for route numbers, there are a maximum of three signs on a pole, with the most important sign at the top. All signs have a reflective layer added on selected parts of the sign as is custom in European countries; most larger signs also have their own illumination.

Vehicle regulations are requirements that automobiles must satisfy in order to be approved for sale or use in a particular country or region. They are usually mandated by legislation, and administered by a government body. The regulations concern aspects such as lighting, controls, crashworthiness, environment protection and theft protection, and might include safety belts or automated features.

Government regulation in the automotive industry directly affects the way cars look, how their components are designed, the safety features that are included, and the overall performance of any given vehicle. As a result, these regulations also have a significant effect on the automotive business by generally increasing production costs while also placing limitations on how cars are sold and marketed. Automotive regulations are designed to benefit the consumer and protect the environment, and automakers can face stiff fines and other penalties if they are not followed.

Driving licence in the United Kingdom

In the United Kingdom, a driving licence is the official document which authorises its holder to operate motor vehicles on highways and other public roads. It is administered in England, Scotland and Wales by the Driver and Vehicle Licensing Agency (DVLA) and in Northern Ireland by the Driver & Vehicle Agency (DVA). A driving licence is required in England, Scotland, and Wales for any person driving a vehicle on any highway or other "road", as defined in s.192 Road Traffic Act 1988, irrespective of the ownership of the land over which the road passes. Similar requirements apply in Northern Ireland under the Road Traffic Order 1981.

Geneva Convention on Road Traffic

The Convention on Road Traffic, commonly known as the Geneva Convention on Road Traffic, is an international treaty promoting the development and safety of international road traffic by establishing certain uniform rules among the contracting parties. The convention addresses minimum mechanical and safety equipment needed to be on board and defines an identification mark to identify the origin of the vehicle. The Convention was prepared and opened for signature by the United Nations Conference on Road and Motor Transport held at Geneva from 23 August to 19 September 1949. It came into force on 26 March 1952. This conference also produced the Protocol on Road Signs and Signals.

The road signs in Poland follow the Vienna Convention on Road Signs and Signals and, therefore, are more or less identical to those in other European countries. Warning signs have yellow background rather than the more common black-on-white design, and therefore similar to the road signs in Greece.

Road traffic control devices are markers, signs and signal devices used to inform, guide and control traffic, including pedestrians, motor vehicle drivers and bicyclists. These devices are usually placed adjacent, over or along the highways, roads, traffic facilities and other public areas that require traffic control.

Glossary of road transport terms Wikipedia glossary

Terminology related to road transport—the transport of passengers or goods on paved routes between places—is diverse, with variation between dialects of English. There may also be regional differences within a single country, and some terms differ based on the side of the road traffic drives on. This glossary is an alphabetical listing of road transport terms.
