If passengers fail to unload, their legs will contact a lightweight bar, line, or pass through a light beam which stops the lift. The lift operator will then help them disembark, reset the safety gate, and initiate the lift restart procedure. While possibly annoying to other passengers on the chairlift, it is preferable to strike the safety gate—that is, it should not be avoided—and stop the lift than be an unexpected downhill passenger. Many lifts are limited in their download capacity; others can transport passengers at 100 percent capacity in either direction.
