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, and by preventing occupants being ejected from the vehicle in a crash or if the vehicle rolls over.
An airbag is a vehicle occupant-restraint system using a bag designed to inflate in milliseconds during a collision and then deflate afterwards. It consists of an airbag cushion, a flexible fabric bag, an inflation module, and an impact sensor. The purpose of the airbag is to provide a vehicle occupant with soft cushioning and restraint during a collision. It can reduce injuries between the flailing occupant and the vehicle's interior.
The Ford Pinto is a subcompact car that was manufactured and marketed by Ford Motor Company in North America from 1970 until 1980. The Pinto was the first subcompact vehicle produced by Ford in North America.
A crash test dummy, or simply dummy, is a full-scale anthropomorphic test device (ATD) that simulates the dimensions, weight proportions and articulation of the human body during a traffic collision. Dummies are used by researchers, automobile and aircraft manufacturers to predict the injuries a person might sustain in a crash. Modern dummies are usually instrumented to record data such as velocity of impact, crushing force, bending, folding, or torque of the body, and deceleration rates during a collision.
A crash test is a form of destructive testing usually performed in order to ensure safe design standards in crashworthiness and crash compatibility for various modes of transportation or related systems and components.
Automotive safety is the study and practice of automotive design, construction, equipment and regulation to minimize the occurrence and consequences of traffic collisions involving motor vehicles. Road traffic safety more broadly includes roadway design.
Corporate average fuel economy (CAFE) standards are regulations in the United States, first enacted by the United States Congress in 1975, after the 1973–74 Arab Oil Embargo, to improve the average fuel economy of cars and light trucks produced for sale in the United States. More recently, efficiency standards were developed and implemented for heavy-duty pickup trucks and commercial medium-duty and heavy-duty vehicles.
A bumper is a structure attached to or integrated with the front and rear ends of a motor vehicle, to absorb impact in a minor collision, ideally minimizing repair costs. Stiff metal bumpers appeared on automobiles as early as 1904 that had a mainly ornamental function. Numerous developments, improvements in materials and technologies, as well as greater focus on functionality for protecting vehicle components and improving safety have changed bumpers over the years. Bumpers ideally minimize height mismatches between vehicles and protect pedestrians from injury. Regulatory measures have been enacted to reduce vehicle repair costs and, more recently, impact on pedestrians.
The National Highway Traffic Safety Administration is an agency of the U.S. federal government, part of the Department of Transportation, focused on transportation safety in the United States.
The Insurance Institute for Highway Safety and Highway Loss Data Institute (IIHS-HLDI) is an American nonprofit organization. It was established in 1959, and it is noted for its safety reviews of vehicles in various simulated traffic situations, including the effectiveness of a vehicle's structural integrity and safety systems during a collision, in addition to examining improvement on such elements.
A side collision is a vehicle crash where the side of one or more vehicles is impacted. These crashes typically occur at intersections, in parking lots, and when two vehicles pass on a multi-lane roadway.
This is a list of numbers of motorcycle deaths in U.S. by year from 1994 to 2014. United States motorcycle fatalities increased every year for 11 years after reaching a historic low of 2,116 fatalities in 1997, then increased to over 5,000 around 2008 and then plateaued in the 4 to 5 thousands range in the 2010s. In nine years motorcycle deaths more than doubled from the late 1990s to 2008. Despite providing less than 1% of miles driven, they made up 15% of traffic deaths in 2012.
Head restraints are an automotive safety feature, attached or integrated into the top of each seat to limit the rearward movement of the adult occupant's head, relative to the torso, in a collision — to prevent or mitigate 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.
Whiplash Protection System (WHIPS) is a system to protect against automotive whiplash injuries introduced by Volvo in 1998. It was launched when the Volvo S80 was released for the 1999 model year and has since been part of the standard equipment of all new Volvo cars.
Sport utility vehicles (SUVs) have been criticized for a variety of environmental and automotive safety reasons. The rise in production and marketing of SUVs in the 2010s and 2020s by auto manufacturers has resulted in over 80% of all new car sales in the United States being SUVs or light trucks by October 2021. This rise in SUV sales has also spilled over into the United Kingdom and the European Union. It has generated calls from car safety advocates to downsize in favor of models such as sedans, wagons, and compacts.
When a person makes a claim for personal injury damages that have resulted from the presence of a defective automobile or component of an automobile, that person asserts a product liability claim. That claim may be against the automobile's manufacturer, the manufacturer of a component part or system, or both, as well as potentially being raised against companies that distributed, sold or installed the part or system that is alleged to be defective.
The head injury criterion (HIC) is a measure of the likelihood of head injury arising from an impact. The HIC can be used to assess safety related to vehicles, personal protective gear, and sport equipment.
Worldwide, it was estimated that 1.25 million people were killed and many millions more were injured in motor vehicle collisions in 2013. This makes motor vehicle collisions the leading cause of death among young adults of 15–29 years of age and the ninth most frequent cause of death for all ages worldwide. In the United States, 40,100 people died and 2.8 million were injured in crashes in 2017, and around 2,000 children under 16 years old die every year.
The World Forum for Harmonization of Vehicle Regulations define AEBS. UN ECE regulation 131 requires a system which can automatically detect a potential forward collision and activate the vehicle braking system to decelerate a vehicle with the purpose of avoiding or mitigating a collision. UN ECE regulation 152 says deceleration has to be at least 5 metres per second squared.
Tesla Autopilot is an advanced driver-assistance system (ADAS) developed by Tesla that amounts to partial vehicle automation. Tesla provides "Base Autopilot" on all vehicles, which includes lane centering and traffic-aware cruise control. Owners may purchase or subscribe to Full Self-Driving (FSD) which adds semi-autonomous navigation that responds to traffic lights and stop signs, lane change assistance, self-parking, and the ability to summon the car from a garage or parking spot.
