Roll-over tests: which tests a car's ability (specifically the pillars holding the roof) to support itself in a dynamic impact.Pole-impact tests: A difficult test which places a large amount of force on a small proportion on the side of the vehicle.
Side-impact tests: these forms of accidents have a very significant likelihood of fatality, as cars do not have a significant crumple zone to absorb the impact forces before an occupant is injured.These are usually conducted at 15-20% of the front vehicle structure. This is the most demanding test because it loads the most force onto the structure of the car at any given speed. Small Overlap tests: this is where only a small portion of the car's structure strikes an object such as a pole or a tree, or if a car were to clip another car.Insurance Institute for Highway Safety (IIHS), EuroNCAP, Australasian New Car Assessment Program (ANCAP) and ASEAN NCAP. This type of testing is done by the U.S.A. These tests are often realized by cars turning into oncoming traffic. These are important, as impact forces (approximately) remain the same as with a frontal impact test, but a smaller fraction of the car is required to absorb all of the force. Moderate Overlap tests: in which only part of the front of the car impacts with a barrier (vehicle).SUVs have been singled out in these tests for a while, due to the high ride-height that they often have. Vehicles usually impact a solid concrete wall at a specified speed, but these can also be vehicle impacting vehicle tests. Frontal-impact tests: which is what most people initially think of when asked about a crash test.
