Abstract: A lightweight vehicle ladder for the recovery and traction of vehicles includes a central recessed portion (48) bordered by longitudinal strengthening ribs (56) and ramps (55) at either end. A plurality of traction members (52), each of which terminates in an upper tire engagement member (54) are disposed within the recessed portion and thereby somewhat protected from the ingress of mud during use in order that traction may be maintained. The underside and topside of the vehicle are formed with complementary shapes in order that a number of the ladders may be stacked one on top of the other to form a laminate of increased strength for application with particularly heavy vehicles.
