Disclosed is a vehicular device comprising a tether. The tether is anchored at a first point to the frame of the vehicle, and at a second point to the knuckle of a front wheel of the vehicle, wherein the knuckle couples the front wheel to the frame. The locations of the first anchor point and second anchor point, along with the length of the tether and the routing of the tether within the vehicle, are selected such that in a collision event between the front wheel and a barrier, when the knuckle becomes separated from the frame, the motion of the front wheel is constrained to exert force on both the barrier and the frame of the vehicle.
