WAC 296-307-52041. Traveling speeds of powered industrial trucks

(1) The operator must observe all traffic regulations, including authorized plant speed limits. (2) The operator must slow down and sound the horn at cross aisles and other locations where vision is obstructed. If the load obstructs a forward view, the driver must travel with the load trailing. Exception: If traveling with the load trailing creates new hazards, it is not required. (3) The operator must ascend and descend grades slowly. (a) At grades over 10 percent, loaded trucks must be driven with the load upgrade. (b) Unloaded trucks should be operated on all grades with the load carrier downgrade. (c) On all grades the load and load carrier must be tilted back if applicable, and raised only as far as necessary to clear the road surface. (4) Under all travel conditions, the truck must be operated at a speed that will permit it to be stopped safely. (5) The driver must slow down for wet and slippery floors. (6) While negotiating turns, the operator must slow to a safe speed and turn the wheel in a smooth, sweeping motion.
