Disclosed is a self deployed, self retracting flotation device for a land hicle, the device including covers hinged to the sides of the vehicle. Inflatable air bags are attached to the covers so that inflating the bags swings up the covers and subsequently deflating the bags allows the covers to swing down. The device is constructed so that the bags protrude from between the cover and the vehicle when inflated and retract to a position between the cover and the vehicle when deflated. A reversible pump operable from within the vehicle is used to inflate or deflate the bags.
