There is disclosed a vehicle (1) for travelling over snow or the like and comprising a straight runner means (19) and one or more curved runners (21, 23, 25) convex towards the straight runner means. When the vehicle is level it travels on the straight runner means in a straight line. By rolling the vehicle to one side, one of the curved runners engages the snow and the vehicle performs a carving turn whose radius is determined by the radius of the runner. Different turn radii are selectable by altering the roll angle of the vehicle. Embodiments are described for use on snow and ice and a wheeled version for use on hard surfaces is also disclosed.
