Driving in dust storms
Dust storms are caused by high winds sweeping across fields or dry desert terrain, sometimes blowing dust onto nearby highways. Although usually brief, dust storms should be taken seriously because they can quickly decrease visibility. If you see a dust storm while driving:
- Turn on your headlights and slow to an appropriate speed.
- If you can safely avoid it, do not enter the dust storm.
- If you need to pull off the road, get as far to the right as possible. Turn off the car and headlights, and set the parking brake. Keep your foot off the brake pedal – other drivers may think you’re a car in motion

Driving in rain
While most people associate Arizona with the desert, the state does experience occasional heavy rainstorms, particularly during the summer monsoon season. If you find yourself driving during one of these storms, keep these safety tips in mind:
- Slow down!
- If your visibility is impeded by heavy rain, slowly pull off to the side of the road as far to the right as possible. Turn off the car and headlights, set the parking brake and keep your foot off the brake pedal.
- Pay attention to hazard signs and roadblocks. If you see a sign that says "Do Not Cross When Flooded", take it seriously and find another way.
- Don’t cross rain-swollen washes. You could get caught in a flash flood.
