CMVSS
The Federal Motor Vehicle Safety Standards (FMVSS) are U.S. federal vehicle regulations specifying design, construction, performance, and durability requirements for motor vehicles and regulated automobile safety-related components, systems, and design features. They are the U.S. counterpart to the UN Regulations developed by the World Forum for Harmonization of Vehicle Regulations and recognized to varying degree by most countries except the United States. Canada has a system of analogous rules called the Canada Motor Vehicle Safety Standards (CMVSS), which overlap substantially but not completely in content and structure with the FMVSS. The FMVSS/CMVSS requirements differ significantly from the international UN requirements, so private import of foreign vehicles not originally manufactured to North American specifications is difficult or impossible. Structure FMVSS are currently codified in Title 49 of the Code of Federal Regulations, Part 571, Subpart B (), with each FMVSS s ...

FMVSS 108
Federal Motor Vehicle Safety Standard 108 (FMVSS 108) regulates all automotive lighting, signalling and reflective devices in the United States. Like all other Federal Motor Vehicle Safety Standards, FMVSS 108 is administered by the United States Department of Transportation's National Highway Traffic Safety Administration. Usage outside of USA Canada Canada's analogous regulation is called ''Canada Motor Vehicle Safety Standard 108'' (CMVSS 108), and is very similar to FMVSS 108. The primary differences are: * CMVSS 108 requires daytime running lamps on all vehicles made since 1 January 1990, while FMVSS 108 permits but does not require DRLs * CMVSS 108, through an adjunct called CMVSS 108.1, permits European headlamps, while FMVSS 108 prohibits them. Both standards differ markedly from the UN (formerly "European") standards used in most other countries worldwide, not only in technical provisions, terminology, and requirements, but in format: each European standard deals w ...

Wing Mirror
A side-view mirror (or side mirror), also known as a wing mirror, is a mirror placed on the exterior of motor vehicles for the purposes of helping the driver see areas behind and to the sides of the vehicle, outside the driver's peripheral vision (in the " blind spot"). Almost all modern cars mount their side mirrors on the doors—normally at the A-pillar—rather than the wings (the portion of the body above the wheel well). The side mirror is equipped for manual or remote vertical and horizontal adjustment so as to provide adequate coverage to drivers of differing height and seated position. Remote adjustment may be mechanical by means of bowden cables, or may be electric by means of geared motors. The mirror glass may also be electrically heated and may include electrochromic dimming to reduce glare to the driver from the headlamps of following vehicles. Increasingly, the side mirror incorporates the vehicle's turn signal repeaters. There is evidence to suggest that mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grey-market Vehicle
Grey import vehicles are new or used motor vehicles and motorcycles legally imported from another country through channels other than the maker's official distribution system. The synonymous term parallel import is sometimes substituted. Car makers frequently arbitrage markets, setting the price according to local market conditions so the same vehicle will have different real prices in different territories. Grey import vehicles circumvent this profit-maximization strategy. Car makers and local distributors sometimes regard grey imports as a threat to their network of franchised dealerships, but independent distributors do not since more cars of an odd brand bring in money from service and spare parts. In order for the arbitrage to work, there must be some means to reduce, eliminate, or reverse whatever savings could be achieved by purchasing the car in the lower-priced territory. Examples of such barriers include regulations preventing import or requiring costly vehicle modific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seat Belts
A seat belt (also known as a safety belt, or spelled seatbelt) is a vehicle safety device designed to secure the driver or a passenger of a vehicle against harmful movement that may result during a collision or a sudden stop. A seat belt reduces the likelihood of death or serious injury in a traffic collision by reducing the force of secondary impacts with interior strike hazards, by keeping occupants positioned correctly for maximum effectiveness of the airbag (if equipped), and by preventing occupants being ejected from the vehicle in a crash or if the vehicle rolls over. When in motion, the driver and passengers are traveling at the same speed as the vehicle. If the vehicle suddenly stops or crashes, the occupants continue at the same speed the vehicle was going before it stopped. A seatbelt applies an opposing force to the driver and passengers to prevent them from falling out or making contact with the interior of the car (especially preventing contact with, or going t ...

Vehicle Regulation
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. History Some countries have had national regulations for a long time. The first steps toward harmonizing vehicle regulations internationally were made in 1952 when WP.29, a working party of experts on vehicles' technical requirements, was created. This resulted in the 1958 Agreement on uniform conditions of approval and mutual recognition of vehicle approvals, components, and parts. This was one of the first international agreements on vehicle regulation, which initially focused on European countries. The European Union played a role in harmonizing regulations between member states. Later ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorcycle Helmet
A motorcycle helmet is a type of helmet used by motorcycle riders. Motorcycle helmets contribute to motorcycle safety by protecting the rider's head in the event of an impact. They reduce the risk of head injury by 69% and the risk of death by 42%. Their use is required by law in many countries. Motorcycle helmets consist of a Polystyrene, polystyrene foam inner shell that absorbs the shock of an impact, and a protective plastic outer layer. Several variations exist, notably helmets that cover the chin area and helmets that do not. Some helmets provide additional conveniences, such as ventilation, face shields, sun visors, ear protection or intercom. Origins The origins of the crash helmet date back to the Brooklands race track in early 1914, when a medical officer, Dr. Eric Gardner, noticed he was seeing a motor cyclist with head injuries about every two weeks. He got a Mr. Moss of Bethnal Green to make canvas and shellac helmets stiff enough to stand a heavy blow and smooth e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Head Restraint
Head restraints (also called headrests) are an automotive safety feature, attached or integrated into the top of each car seat, seat to limit the rearward movement of the adult occupant's head, relative to the torso, in a Traffic collision, collision — to prevent or mitigate whiplash (medicine), whiplash or injury to the cervical vertebrae. Since their mandatory introduction in some countries beginning in the late 1960s, head restraints have prevented or mitigated thousands of serious injuries. A patent for an automobile "headrest" was granted to Benjamin Katz, a resident of Oakland, California, in 1921. Additional patents for such devices were issued in 1930 and in 1950, and subsequently. The major U. K. supplier of head restraints, Karobes, filed patents in the late 1950s and was still competitive in 1973 when British tests evaluated the quality of these devices. Optional head restraints began appearing on North American cars in the mid-1960s, and were mandated by the U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FMVSS 208
Federal Motor Vehicle Safety Standard 208 (FMVSS 208) regulates automotive occupant crash protection in the United States. Like all other Federal Motor Vehicle Safety Standards, FMVSS 208 is administered by the United States Department of Transportation's National Highway Traffic Safety Administration. This standard originally specified the type of occupant restraints (i.e., seat belts) required. It was amended to specify performance requirements for anthropomorphic test dummies seated in the front outboard seats of passenger cars and of certain multi-purpose passenger vehicles, trucks, and buses, including the active and passive restraint systems. The purpose of the standard is to reduce the number of fatalities and the number and severity of injuries to occupants involved in frontal crashes. See also *Seat belt *Airbag *FMVSS The Federal Motor Vehicle Safety Standards (FMVSS) are U.S. federal vehicle regulations specifying design, construction, performance, and durability re ...

Tire-pressure Monitoring System
A tire-pressure monitoring system (TPMS) monitors the air pressure inside the pneumatic tires on vehicles. A TPMS reports real-time tire-pressure information to the driver, using either a gauge, a pictogram display, or a simple low-pressure warning light. TPMS can be divided into two different types – direct (dTPMS) and indirect (iTPMS). TPMS are installed either when the vehicle is made or after the vehicle is put to use. The goal of a TPMS is avoiding traffic accidents, poor fuel economy, and increased tire wear due to under-inflated tires through early recognition of a hazardous state of the tires. This functionality first appeared in luxury vehicles in Europe in the 1980s, while mass-market adoption followed the USA passing the 2000 TREAD Act after the Firestone and Ford tire controversy. Mandates for TPMS technology in new cars have continued to proliferate in the 21st century in Russia, the EU, Japan, South Korea and many other Asian countries. From November 2014 ...

Roof Crush
Roof crush is the failure and displacement of an automobile roof into the passenger compartment during a rollover accident. Every year approximately 10,000 Americans are killed in rollover accidents, accounting for about 30% of all light vehicle occupant fatalities. The number of occupant injuries is significantly higher. The relationship between injury levels and intrusion or roof crush has been statistically established, but the mechanism has been thought sometimes to be somewhat obscure. Theories advocating the idea that rollover injuries are caused by the occupants "falling" or "diving" into the vehicles interior have been advanced, but the severity of these events, and thus their potential for causing injury, has been questioned. Observations from school bus and heavy truck rollovers also suggests that the fall and dive theories are incorrect and that another theory of the mechanism of injury in rollover accidents is required, one that relates injury to the intrusion of ...

Speedometer
A speedometer or speed meter is a gauge that measures and displays the instantaneous speed of a vehicle. Now universally fitted to motor vehicles, they started to be available as options in the early 20th century, and as standard equipment from about 1910 onwards. Other vehicles may use devices analogous to the speedometer with different means of sensing speed, eg. boats use a pit log, while aircraft use an airspeed indicator. Charles Babbage is credited with creating an early type of a speedometer, which was usually fitted to locomotives. The electric speedometer was invented by the Croatian Josip Belušić in 1888 and was originally called a velocimeter. Operation The speedometer was originally patented by Josip Belušić (Giuseppe Bellussich) in 1888. He presented his invention at the 1889 Exposition Universelle in Paris. His invention had a pointer and a magnet, using electricity to work. German inventor Otto Schultze patented his version (which, like Belušić's, ra ...

Motorcycle Braking Systems
Motorcycle braking systems have varied throughout time, as motorcycles evolved from bicycles with an engine attached, to the prototype motorcycles seen racing in MotoGP. Most systems work by converting kinetic energy into thermal energy (heat) by friction. On motorcycles, approximately 70% of the braking effort is performed by the front brake. This however can vary for individual motorcycles; longer-wheelbase types having more weight biased rearward, such as cruisers and tourers, can have a`greater effort applied by the rear brake. In contrast, sports bikes with a shorter wheelbase and more vertical fork geometry can tolerate higher front braking loads. For these reasons, motorcycles tend to have a vastly more powerful front brake compared to the rear. History Early motorcycles which were essentially a bicycle with a motor attached and did not have any braking system beyond slowing the motorcycle down and putting a foot out. One of the first motorcycles to have any sort of braki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
