Tips for Driving in the Rain
Monitor the news for weather related information. If there is a flash flood watch or warning in effect, stay off the roads.
Avoid areas that are already flooded and do not attempt to cross a flooded roadway.
Recognize flood-prone areas such as low water crossings, dips, and ditches, and do not attempt to cross if flooding is possible.
Be cautious when driving at night or in unfamiliar areas when it is harder to recognize flood dangers.
