With the arrival of the monsoon, the Arizona Department of Public Safety is warning drivers of the hazards they face during blowing dust and torrential rains. DPS says the most important thing drivers can do is slow down. Vehicles have less traction on wet roads, and slower driving speeds allow for safer braking and stopping distances. Leaving plenty of room between vehicles also helps with braking distances.
Do not cross roads that have been closed with barricades, as it may not be possible to tell how fast the water is flowing or its depth. It is illegal to cross blocked roads in Arizona.
During storms, drive with your lights on to improve visibility to other vehicles. And if you find yourself in a dirt storm and want to stop, do not stop on the road or in the emergency shoulder area. Instead, pull completely off the road, turn off your lights and take your foot off the brake.
