Small Overlap Crash Test
The small overlap test crashes a car into a barrier with only a narrow part of the front, outside the main crash structure.
What is Small Overlap Crash Test?
It was introduced by the US IIHS in 2012. It hits the area beyond the main longitudinal rails, so the wheel and pillar take much of the load. Early results led many carmakers to strengthen their front structures. IIHS later added a passenger-side version of the test so both sides of the car are checked.
How it works
Because the main crash rails are bypassed, the test checks whether the passenger cell resists intrusion and the car glances away.
Why it matters for your car
A car that scores well in a full-width test can still do worse in a small overlap crash. Check which test version and year a rating refers to.
