A lift truck 10, 110 includes a frame 12, 112 a pair of laterally spaced apart outriggers 24, 124 extending from the frame, and a load handling assembly 26, 126 secured to the frame adjacent to the outriggers. The load handling assembly includes a mast assembly 28, 128 positioned between the outriggers and a carriage assembly 30, 130 including fork structure for supporting a load on the load handling assembly. The carriage assembly is movable vertically and/or longitudinally relative to the frame and/or the fork structure is movable laterally with respect to the mast assembly. Optical sensor structure 60 of the truck monitors respective areas around the outriggers for a portion of the load 200 carried on the fork structure. A vehicle controller 52, 152 receives a signal from the optical sensor structure and restricts movement of the carriage assembly to prevent contact between the load and at least one or the outriggers if the signal from the optical sensor structure indicates that a portion of the load carried on the fork structure is positioned in at least one of the respective areas of the outriggers.
