FMVSS
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 FMV ...

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] |
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. Evolution FMVSS 108 is codified in Title 49 of the Code of Federal Regulations Part 571, Section 108. The most recent version was published by NHTSA for comment in December 2007, and since then, it has been amended in April 2011, August 2011, January 2012, December 2012, December 2015, February 2016, and February 2022. When it was initially published in 1968, Motor Vehicle Safety Standard No. 108 was part of 49 CFR 371.21, incorporating several SAE recommended practices by reference. The 1969 version of FMVSS 108 allowed the use of two headlamps, each in diameter, or four smaller headlamps. 2022 Amendment In February 2022, FMVSS 108 was amended to allow a ...

National Highway Traffic Safety Administration
The National Highway Traffic Safety Administration (NHTSA ) is an agency of the U.S. federal government, part of the Department of Transportation, focused on automobile safety regulations. NHTSA is charged with writing and enforcing Federal Motor Vehicle Safety Standards (FMVSS), regulations for motor vehicle theft resistance, and fuel economy, as part of the Corporate Average Fuel Economy (CAFE) system. FMVSS 209 was the first standard to become effective on March 1, 1967. NHTSA licenses vehicle manufacturers and importers, allows or blocks the import of vehicles and safety-regulated vehicle parts, administers the vehicle identification number (VIN) system, develops the crash test dummies used in U.S. safety testing as well as the test protocols themselves, and provides vehicle insurance cost information. The agency has asserted preemptive regulatory authority over greenhouse gas emissions, but this has been disputed by state regulatory agencies such as the Cali ...

Electronic Stability Control
Electronic stability control (ESC), also referred to as electronic stability program (ESP) or dynamic stability control (DSC), is a computerized technology that improves a car handling, vehicle's stability by detecting and reducing loss of Traction (engineering), traction (skid (automobile), skidding). When ESC detects loss of steering control, it automatically applies the brakes to help steer the vehicle where the driver intends to go. Braking is automatically applied to wheels individually, such as the outer front wheel to counter oversteer, or the inner rear wheel to counter understeer. Some ESC systems also reduce engine power until control is regained. ESC does not improve a vehicle's cornering performance; instead, it helps reduce the chance of the driver losing control of the vehicle on a slippery road. According to the U.S. National Highway Traffic Safety Administration and the Insurance Institute for Highway Safety in 2004 and 2006, one-third of fatal accidents could be ...

Brake Fluid
Brake fluid is a type of hydraulic fluid used in hydraulic brake and hydraulic clutch applications in automobiles, motorcycles, light trucks, and some bicycles. It is used to transfer force into pressure, and to amplify braking force. It works because liquids are not appreciably compressible. Most brake fluids used today are glycol-ether based, but mineral oil (''Citroën/Rolls-Royce liquide hydraulique minéral'' ( LHM)) and silicone-based (DOT 5) fluids are also available. The origins of modern braking systems date back to an event more than a century ago - in 1917, Scotsman Malcolm Lockheed patented a hydraulic actuated braking system. Initially, vegetable oil was used as a working fluid. But it did not meet the most basic requirements, and in the process of evolution, special brake fluids were created, which consist of a base and a package of additives (thickeners, anti-corrosion additives, colorants). Standards Most brake fluids are manufactured to meet standards se ... [...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 halts or crashes, the occupants continue at the same speed the vehicle was going before it stopped. A seat belt 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 ...

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 An airbag is a vehicle occupant-restraint system using a bag designed to inflate in milliseconds during a collision and then deflate afterwards. It consis ...

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 British 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.S. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 TPMS, 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 Transportation Recall Enhancement, Accountability and Documentation Act, TREAD Act after the Firestone and Ford tire controversy. Mandates for TPMS technology in new cars have continued to proliferate in the 21st century i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FMVSS 116
Federal Motor Vehicle Safety Standard 116 (FMVSS 116) regulates motor vehicle brake fluids in the United States. Like all other Federal Motor Vehicle Safety Standards, FMVSS 116 is administered by the United States Department of Transportation's National Highway Traffic Safety Administration. This standard specifies requirements for fluids for use in hydraulic brake systems of motor vehicles, containers for these fluids, and labeling of the containers. The purpose is to reduce failures in hydraulic braking systems of motor vehicles which may occur because of the manufacture or use of improper or contaminated fluid. The standard applies to all fluid use of passenger cars, multipurpose passenger vehicles, trucks, buses, trailers and motorcycles equipped with a hydraulic brake system.
