Example Use:
At a busy intersection where drivers are not allowed to proceed straight and must make either a left or right turn, a Hazard Board Sign can be strategically placed to enhance safety and clarify the permissible directions of travel. For example, the sign could be positioned prominently at the approach to the intersection emphasizing the prohibition of straight travel. To further assist drivers, the other signs could also include supplementary text, such as 'LEFT TURN ONLY' and 'RIGHT TURN ONLY' beside the respective arrows. This setup would clearly communicate to approaching drivers that they cannot proceed straight through the intersection and must instead choose to turn either left and/or right, helping to prevent confusion and enhance the overall safety of the intersection.
