Abstract
An automatically extending and retracting step system according to the solution may reside in a retracted state when the deck of a car-carrying vehicle is substantially horizontal to the ground, i.e. when the deck is in a payload state. Advantageously, when the deck is tilted and extended to a ramp state for receiving cargo, the step system according to the solution extends laterally outward from beneath the deck, thereby providing a convenient and visible step for a user to use in getting down from the deck. When the deck is returned from the ramp state to its payload state, the step automatically retracts to a travel state beneath the deck.
