A slide channel is slidably received within each fixed channel for relative sliding movement therebetween in the lateral direction. Guard material is suspended from the slide channel to be arranged for catching debris thrown rearward from wheels of the vehicle. The guard material and the slide channel are arranged to be slidably removable together from the fixed channel while the fixed channel can remain secured to the vehicle at spaced positions along the vehicle to take advantage of both supporting the guard material along the full width of the vehicle in a stable manner while also permitting the guard material to be readily slidably removed from the vehicle when not in use. ## Claims ### Claim 1 A mud guard assembly for a vehicle having a chassis supported for longitudinal travel in a forward direction, the assembly comprising: at least one fixed channel arranged to be supported in fixed relation to the chassis of the vehicle at a rear of the vehicle to extend laterally in relation to the longitudinal travel of the vehicle;
