[1] However, the primary vector of traffic-related deaths and injuries is the disproportionate mass and velocity of an automobile compared to that of the predominant victim, the pedestrian.
[4] Risk compensation theory has been used in arguments against safety devices, regulations and modifications of vehicles despite the efficacy of saving lives.
The Center for Internet and Society at Stanford Law School claims that "Some ninety percent of motor vehicle crashes are caused at least in part by human error".
Deaths and injuries from these roadway crashes result in increased costs to employers and lost productivity in addition to their toll in human suffering.
Workers outside the motor carrier industry routinely operate company-owned vehicles for deliveries, sales and repair calls, client visits, etc.
In these instances, the employer providing the vehicle generally plays a major role in setting safety, maintenance, and training policy.
School buses and semi-trailer trucks in North America are required to bear retroreflective strips outlining their side and rear perimeters for greater conspicuity at night.
[citation needed] Many different inventions and ideas which may or may not have been practical about auto safety have been put forward but never made it to a production car.
Such items include the driver seat in the middle (to give the person a better view)[21] (the exception being the McLaren F1 super car) and control stick steering.
)[43] In 1958, the United Nations established the World Forum for Harmonization of Vehicle Regulations, an international standards body advancing auto safety.
Many of the most life saving safety innovations, like seat belts and roll cage construction were brought to market under its auspices.
[47] Effective in 1966, US-market passenger cars were required to be equipped with padded instrument panels, front and rear outboard lap belts, and white reverse (backup) lamps.
The National Transportation Safety Board (NTSB) was created as an independent organization on April 1, 1967, but was reliant on the DOT for administration and funding.
These required shoulder belts for left and right front-seat vehicle occupants, side marker lights, collapsible steering columns, and other safety features.
[51] In 1979, NHTSA began crash-testing popular cars and publishing the results, to inform consumers and encourage manufacturers to improve the safety of their vehicles.
[citation needed] Also in 2003, the National Highway Traffic Safety Administration (NHTSA) introduced a female counterpart crash test dummy of Hybrid III.
[63] In 2009, Citroën became the first manufacturer to feature "Snowmotion", an Intelligent Anti Skid system developed in conjunction with Bosch, which gives drivers a level of control in extreme ice or snow conditions similar to a 4x4.
[68] In 2014, ESP (Electronic Stability Program) and TPMS became mandatory in the European Union, with also the driver seat belt reminder and the ISOFIX system, under General Safety Regulation (EC) No 661/2009.
Research on the trends in use of heavy vehicles indicate that a significant difference between the US and other countries is the relatively high prevalence of pickup trucks and SUVs in the US.
[85] However, other factors exert significant influence; Canada has lower roadway death and injury rates despite a vehicle mix comparable to that of the US.
[91] In rear-end collisions, female drivers face a higher risk of whiplash injuries when compared to their male counterparts due to their lighter weight which causes them to be propelled forward more rapidly.
This means that vehicle restraint systems such as airbags and seat belts, far from being effective, are hazardous if used to restrain young children.
[citation needed] Within Europe ECE Regulation R44 dictates that children below 150 cm must travel in a child restraint that is appropriate for their weight.
For instance, in the United Kingdom, children must travel in a child restraint until they are 135 cm tall or reach 12 years of age, which ever comes soonest.
[94] Sweden specify that a child or an adult shorter than 140 cm is legally forbidden to ride in a place with an active airbag in front of it.
[citation needed] The majority of medical professionals and biomechanical engineers agree that children below the age of two years old are much safer if they travel in a rearward facing child restraint.
[citation needed] Very young children can perish from heat or cold if left unattended in a parked car, whether deliberately or through absent-mindedness.
[101] Some countries, such as Australia, the United States, Canada and New Zealand, have graduated levels of driver's licence, with special rules.
In Romania, the maximum speed of vehicles driven by new drivers (less than one year in experience) is 20 km/h lower than the national standard (except villages, towns and cities).
In Victoria, Australia, safety features checked include the structure of the vehicle, the tires (depth of tread), the wheels, the engine, steering, suspension, brakes, and lights and seatbelts.
