Small overlap front

The small overlap front test represents a crash in which the front corner of a vehicle collides with another vehicle or an object like a tree or utility pole.

Each vehicle is tested twice — once with the overlap on the driver side and once on the passenger side. The severity of a frontal crash depends on the vehicle’s weight, so ratings in this test can only be compared among vehicles of similar weight.

How the test is run

  • A vehicle travels at 40 mph into a rigid barrier with 25% of the vehicle’s front overlapping.
  • A Hybrid III dummy representing an average-size male is belted in the driver seat; a second one is belted in the front passenger seat for the passenger-side test.

How vehicles are evaluated

  • We measure intrusion into the occupant compartment at key locations.
  • Sensors in the head, neck, chest, legs and feet of the dummy record injury risk.
  • High-speed film and greasepaint help us see the movement of the dummies during the crash so we can evaluate how well the seat belts and airbags work.
