Diagonal drop-off testing is done by driving diagonally toward a curb and turning toward it at varying distances.
The 3-step test is done by driving directly toward three (or more) steps.
The swish test is performed by attempting to intentionally turn and drive the wheelchair off a curb from a standstill after the drop-off protection had already stopped the chair.
Drop-off detection is considered a failure if the wheelchair falls off the curb or if any part of the wheelchair (typically a caster) goes off the curb when the wheelchair comes to a stop. In most cases when there was a failure reported, a caster went off the curb, resulting in the wheelchair being tilted and unable to get back up onto the step. The wheelchair did not tip over completely in any of the tests.
Results are reported as a ratio of the number of tests passed to the total number of tests performed.
