If you encounter standing water across a road in Arizona during monsoon season, the correct action is to:
Drive through slowly if the water looks shallow.
Even shallow-looking water can hide washouts or deep channels.
Turn around and find another route.
Follow a larger vehicle through.
Another vehicle's wake creates additional current and hazard.
Drive through at high speed to create momentum.
Speed increases loss of control and hydroplaning.
"Turn Around, Don't Drown" is the Arizona DOT and National Weather Service mantra. Just 6 inches of moving water can knock an adult off their feet; 12–18 inches can float most cars. Roads in arroyos and washes often have hidden washouts. Always turn around and find another route — no destination is worth the risk.
