Are elevators able to drop floors?

For example, could an elevator go up to the 10th floor, then suddenly drop down to the ninth floor (think tower of terror)?

Every passenger elevator built in the past 50+ years has numerous independent safety mechanisms that prevent the elevator from moving downward faster than the elevator is designed for. Any significant downward speed detected by any of these systems automatically applies breaks and stops the elevator. Only an elevator technician is able to reset the safety systems. The elevator requires a re-inspection after any safety system activated before it is certified for passenger use again. All elevators are regularly inspected to ensure that the components including the safety systems are in good working order.
