This NHTSA collision test shows what happens when a Volkswagen New Beetle slides sideways into a utility pole or a tree. Two cars are involved in a side collision at an intersection in Tokyo, Japan. A side collision is a vehicle crash where the side of one or more vehicles is impacted.
Another type of tripped rollover occurs due to a collision with another vehicle or object. These occur when the collision causes the vehicle to become unstable, such as when a narrow object causes one side of the vehicle to accelerate upwards, but not the other. Turned down guard rail end sections have been shown to do this. A side impact can ...
The more serious risk is a collision with oncoming traffic. Since this is nearly a head-on collision, injuries are common. It is the most common cause of fatalities in a built-up area. Another major risk is involvement in a rear-end collision while waiting for a gap in oncoming traffic. Countermeasures for this type of collision include:
Much cheaper collision reduction methods are to improve road markings, to reduce speeds and to separate traffic with wide central hatching. [3] Sealing of safety zones along the side of the road (also known as a hard shoulder) can also reduce the risk of head-on collisions caused by steering over-correction. [9]
Crash simulations are used to investigate the safety of the car occupants during impacts on the front end structure of the car in a "head-on collision" or "frontal impact", the lateral structure of the car in a “side collision” or “side impact”, the rear end structure of a car in a "rear-end collision" or “rear impact”, and the roof structure of the car when it overturns during a ...
A traffic collision in Japan, 2007 The aftermath of an accident involving a jackknifing truck, Mozambique, Africa. 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.
Pole-impact tests: A difficult test which places a large amount of force on a small proportion on the side of the vehicle. Roll-over tests: which tests a car's ability (specifically the pillars holding the roof) to support itself in a dynamic impact. More recently, dynamic rollover tests have been proposed in lieu of static crush testing (video).
The idea is to more widely distribute the energy in a side collision across the whole side of the car rather than having the b-pillar absorb it all. [6] Driver and passenger seat are mounted on transverse steel rails, [10] not bolted to the floor as per the standard configuration. [11]
