Surface water on the highway
Water on the highway can be from various sources such as, overflowing watercourses like ditches or rivers, blocked drainage systems, utility company issues or from private land.
In the majority of cases after heavy rainfall it may take a while for the water to drain from the carriageway. This is due to the sheer volume of water that the drainage system is trying to take. This is perfectly normal, as is water at the edge of a carriageway following rain.
Please allow at least two hours after the rain stops before reporting any standing water on a highway.
