I think if you look over all the posts to this discussion you'll see far more similarities than differences in the responses. The issue here is the oversimplification of the phrase "right of way" that implies only one participant has the requirement to take an action (yield to the other participant). In practice, this oversimplification can contribute to an unsafe operation.
Pedestrians need to be trained to do their best to stay out of the path of a lift truck, and lift truck operators need to be trained to slow down whenever pedestrians are near and yield if a pedestrian is in their path. So ultimately, you could say that lift truck operators must yield to pedestrians if the pedestrian does not yield to them first.
In addition, management needs to make a concerted effort to eliminate as much vehicle/pedestrian interaction as is practical. Proper facility design should try to keep pedestrians out of heavy lift truck traffic lanes and keep lift trucks out of pedestrian work areas. Proper supervision should prevent pedestrians from mindlessly roaming or standing around in lift truck traffic areas and monitor lift truck operators to make sure they are slowing down when operating in areas where pedestrians are present. I firmly believe that a lack of adequate supervision is the most significant factor in the majority of lift truck accidents. It doesn't matter how clearly you've defined "right of way" or how many "safety first" banners you have hanging in your facility; if your supervisors don't stop a lift truck operator when they observe him driving too fast, you don't have a safety program.
