The Hidden Danger - Low-Water Crossing

road closed
  • Nearly half of all flash flood fatalities are vehicle related! When driving your automobile during flood conditions, look out for flooding at highway dips, bridges and low areas.
  • Even the largest and heaviest of vehicles will float. Two feet of water will carry most cars away.
  • As little as six inches of water may cause you to lose control of your vehicle. Do not drive through flowing water!
  • A hidden danger awaits motorists where a road without a bridge dips across a creek bed.
  • Motorists develop false confidence when they normally or frequently pass through a dry low-water crossing.
  • Road beds may have been scoured or even washed away during flooding creating unsafe driving conditions.
  • Those who repeatedly drive through flooded low-water crossings may not recognize the dangers of a small increase in the water level.
  • Driving too fast through low water will cause the vehicle to hydroplane and lose contact with the road surface.
  • Visibility is limited at night increasing the vulnerability of the driver to any hidden dangers.
  • Heed all flood and flash flood watches and warnings.
  • Remain aware of road conditions!
