Insurance Institute For Highway Safety

The organization’s activities are aimed at reducing the number of traffic accidents, damage, and the severity of injuries sustained in accidents. The Institute carries out research, makes safety ratings of popular passenger cars, as well as consumer goods related to road safety, such as children’s car restraints.

Frontal test with overlapping

The frontal crash test conducted by the Institute differs from the similar test conducted by the American government Agency NHTSA “new Car Assessment Program“, in that part, which concerns the displacement of the deformable obstacle relative to the front of the car. To be more precise, in this test, the deformable barrier covers only 40% of the front of the test vehicle, moving at a speed of about 40 miles per hour (about 64 kilometers per hour). It is because the obstacle is met by only 40% of the front of the car that this test more accurately shows the structural strength of the car, as opposed to the NHTSA test, in which the entire front of the car meets the obstacle. The Insurance Institute for road safety started this type of test in January 1995.

Front tests with a small overlap area

On August 14, 2012, the Institute presented to the public the results of a new, more stringent crash test with partial overlap of the front zone of the car. The new test, in addition to the 40 percent overlap test introduced in 1995, is conducted at 25 percent overlap with an obstacle in the front of a vehicle traveling at a speed of approximately 40 miles per hour (about 64 kilometers per hour). The new crash test is much more demanding on the structure of the vehicle than the 40% overlap test. According to the results of the first cycle of crash tests, most of the tested cars showed poor results, and only three cars were rated “Good” and “Acceptable”.

The system of evaluation of the results of this crash test is largely similar to the system used in the tests with 40 percent overlap, but it has some fundamental differences; damage assessment of thigh/hip joint and lower part of the legs and feet replaced the damage assessment of the legs and feet. Thus, high scores on the results of this test cannot be achieved in cases of incomplete disclosure of the front airbags and safety shutters (due to the strong lateral acceleration resulting from the test).
