The driver's seat is placed on a sled to mimic rear-end collisions at 20 mph. Rear-end collisions at low to moderate speeds typically do not result in serious injuries but they are common. [35] In 2005 the IIHS estimated 25% of medical costs were related to whiplash injuries. The head restraint evaluation test was discontinued in 2022. [36]
In the 2016 Berlin truck attack, the vehicle used was brought to a stop by its automatic braking system. [39] Collision avoidance features are rapidly making their way into the new vehicle fleet. In a study of police-reported crashes, automatic emergency braking was found to reduce the incidence of rear-end crashes by 39 percent. [40]
A rear-end collision, often called rear-ending or, in the UK, a shunt, occurs when a forward-moving vehicle crashes into the back of another vehicle (often stationary) in front of it. Similarly, rear-end rail collisions occur when a train runs into the end of a preceding train on the same track. [1] Common factors contributing to rear-end ...
SAE J2807. SAE J2807 is an SAE standard for determining the towing capacity of passenger cars, multipurpose passenger vehicles, and trucks. [1] It was written to allow consumers to more accurately compare vehicles from different manufacturers. First released in 2008, it has been periodically updated, with the 2020 version being the most current.
The type of brake system in use only affects trucks and large mass vehicles, which cannot supply enough force to match the static frictional force. [1] [Note 2] The braking distance is one of two principal components of the total stopping distance. The other component is the reaction distance, which is the product of the speed and the ...
The first standardized 35 mph (56 km/h) front crash test was on May 21, 1979, and the first results were released on October 15 that year. The agency established a frontal impact test protocol based on Federal Motor Vehicle Safety Standard 208 ("Occupant Crash Protection"), except that the frontal 4 NCAP test is conducted at 35 mph (56 km/h ...

[8] The first production R1T was manufactured in Illinois on September 28th 2021, and was delivered to a ...
Automatic train operation. Unmanned surface vehicle. Vehicular automation. v. t. e. In legal terminology, the assured clear distance ahead ( ACDA) is the distance ahead of any terrestrial locomotive device such as a land vehicle, typically an automobile, or watercraft, within which they should be able to bring the device to a halt.
