When heavy rains fall in Montana, drivers run the risk of hydroplaning. This occurs when the tires of a car encounter more water beneath them than they can handle, creating a thin layer of water between the tires and the street. The tires will therefore be floating above the road. The loss of traction can cause the car to slide or skid uncontrollably, crashing if the driver reacts in the wrong way.
It's not unusual for some rural intersections in Montana to be governed solely by a stop sign. While this can be an effective way to manage traffic flow in some areas, it may not be the best option in locations where there's a higher risk of vehicle collisions. In one such area following a fatal accident in North Carolina, vegetation was cleared to make the stop sign more visible, and signs were posted announcing that a stop sign was ahead. However, there were two more serious accidents at the same interaction. The next step taken was to install a rural roundabout, which proved to be a more effective solution.
