  • ROAD MAY FLOOD (W8-18) - used on a roadway section with frequent flooding.
  • WATER CROSSING (W8-18aT) - used on a roadway section (dip or ford) normally underwater; not where water occasionally crosses roadway due to heavy rain or flash floods.

Flood Gauge Assembly

The flood gauge assembly (FGA) consists of the FLOOD GAUGE (W8-19aTP) plaque and Depth Gauge (W8-19) sign. The FGA assembly should be used in conjunction with signs ROAD MAY FLOOD (W8-18), WATER CROSSING (W8-18aT) or WHEN FLOODED TURN AROUND DON'T DROWN (W8-18bT).
