The label says to me that the way in which the procession will pass and set to go through at any time in advance. Who use the road to travel planner correctly. The procession will be even more chaotic. And reduce accidents to occur.
By installing signs that what's the procession to pass, and that through at any time in advance. The user can use the planned road trip properly. A procession will have more regulation and reduce accidents will happen.
Tell him to stop by the way, what will be the procession through, and set it to any time in advance through the roads will be a procession of planning the trip. It will be a more organized and reduce accident that will occur.
