Generally, if two vehicles have similar physical structures, crashing into another car is equivalent to crashing into a rigid immovable surface (like a wall) at half of the closing speed. This means that rear-ending a stationary car while travelling at 50 km/h (30 mph) is equivalent, in terms of deceleration, to crashing into a wall at 25 km/h ...
A traffic collision in Tokyo, Japan, 2007 The aftermath of an accident involving a jackknifing truck, near Inhassoro, Mozambique. A traffic collision, also known as a motor vehicle collision, or car crash, occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other moving or stationary obstruction, such as a tree, pole or building.
Systematic motor-vehicle safety efforts began during the 1960s. In 1960, unintentional injuries caused 93,803 deaths; [5] 41% were associated with motor-vehicle crashes. In 1966, after Congress and the general public had become thoroughly horrified by five years of skyrocketing motor-vehicle-related fatality rates, the enactment of the Highway Safety Act created the National Highway Safety ...
Worldwide, it was estimated that 1.25 million people were killed and many millions more were injured in motor vehicle collisions in 2013. [2] This makes motor vehicle collisions the leading cause of death among young adults of 15–29 years of age (360,000 die a year) and the ninth most frequent cause of death for all ages worldwide. [3]
The latest version tilts the rear seat upward, placing the passenger in a more ideal crash position if it detects a front or rear impact. [60] 2012: Higher speed APCS on the Lexus LS enables deceleration from up to 37 mph (60 km/h), compared to the previous of 25 mph (40 km/h). The higher-speed APCS uses the same technologies as the current APCs.
Speed limits, traffic density, topography, climate and many other factors affect the divergent accident rates by state. Speed limits in Texas, Utah, and Rhode Island are prima facie rather than absolute. This allows motorists in those states to defend against a speeding charge if it can be proven that the speed was reasonable and prudent.
The 2010 Cochrane Review of speed cameras for the prevention of road traffic injuries and deaths [2] reported that all 28 studies accepted by the authors found the effect of speed cameras to be a reduction in all crashes, injury crashes, and death or severe injury crashes. "Twenty eight studies measured the effect on crashes.
In May 2023, the world's first female crash test dummy was used in a crash test at the Swedish National Road and Transport Research Institute in Linköping, Sweden. Dr. Astrid Linder led the team of researchers to develop the female crash test dummy which represented the height and weight of women at the 50th and 25th percentiles. [41]
