Abstract
In one embodiment, a safety trailer has semi-tractor hitches at both ends and a safety wall that is fixed to one side of the trailer. That side, however, can be changed to the right or left side of the road, depending on the end to which the truck attaches. A caboose can be attached at the end of the trailer opposite the tractor to provide additional lighting and impact protection. Optionally, the trailer can be equipped with overhead protection, lighting, ventilation, onboard hydraulics, compressors, generators and other equipment, as well as related fuel, water, storage and restroom facilities and other amenities.

A mobile barrier for use in military, riot control, and terrorism prevention operations comprising:
- (a) first and second platforms;
- (b) a plurality of interconnected wall sections positioned between and connected to the first and second platforms, the plurality of wall sections defining a protected work area on a side of the trailer;
- (c) wherein the barrier further comprises a caboose having a first set of wheels and a second set of wheels, wherein the second set of wheels are attached to an axle and wherein the caboose further comprises a mechanism for selectively locking and unlocking a tie rod from engagement with the axle, said caboose being configured to be steerable in a steering mode and not steerable in a travel mode and
- (d) wherein when the caboose is in steering mode the second set of wheels of the caboose are steerable and the mechanism for selectively locking and unlocking the tie rod is in an unlocked position and wherein the second set of wheels rotate relative to the axle and wherein the first set of wheels of the caboose are elevated above and not in contact with a travel surface;
- and
- (e) wherein when the caboose is in travel mode the second set of wheels of the caboose are not steerable and the mechanism for selectively locking and unlocking the tie rod is in a locked position and wherein the second set of wheels do not rotate and wherein the first set of wheels of the caboose are in contact with a travel surface.
