The 'elk test' is an extreme test of a car's handling.

In the elk test, sometimes known as the moose test, the driver swerves to avoid an obstacle, then steers back onto the original course. The test is intended to mimic the action of a driver faced with an elk (or moose) wandering onto the road unexpectedly.

The elk test was made famous in 1997 when Swedish journalist Robert Collin tested the Mercedes-Benz A-class and found it was prone to roll over in such a manoeuvre – prompting an expensive and embarrassing recall of early A-class cars by Mercedes.
