AZDOT Special Road Conditions 2 — Questions and Answers
Question 1: When driving on a highway in Arizona during a dust storm, which action is recommended if visibility drops to near zero?
- Pull completely off the road, turn off lights, and wait (Correct answer)
- Turn on hazard lights and slow to 15 mph
- Exit the highway at the nearest ramp immediately
- Follow the taillights of the vehicle ahead closely
Correct answer: Pull completely off the road, turn off lights, and wait
Arizona's 'Pull Aside, Stay Alive' campaign advises drivers to pull completely off the pavement, turn off all lights, and keep feet off the brake to avoid attracting other drivers into the dust cloud.
Question 2: In Arizona, what does a 'Dust Storm Area' warning sign indicate?
- You are entering a zone where sudden dust storms are common (Correct answer)
- A dust storm is currently active ahead
- Road construction is creating dust conditions
- Loose gravel may cause reduced visibility
Correct answer: You are entering a zone where sudden dust storms are common
A 'Dust Storm Area' sign warns that the region ahead is historically prone to sudden haboobs or dust storms, urging drivers to be prepared.
Question 3: When approaching a flooded wash in Arizona, what should you do if water depth is unknown?
- Turn around and find an alternate route (Correct answer)
- Drive through slowly at 5 mph to test depth
- Wait 10 minutes for water to recede before crossing
- Follow another vehicle through to gauge safety
Correct answer: Turn around and find an alternate route
Arizona's 'Turn Around, Don't Drown' rule means you should never attempt to cross a flooded roadway when the depth is unknown — just 6 inches of moving water can knock a person down and 2 feet can sweep a car away.
Question 4: Which condition makes black ice most likely to form on Arizona roads?
- Clear skies after overnight temperatures near freezing with prior moisture (Correct answer)
- Afternoon sunshine following a light rain shower
- Daytime temperatures above 50°F on dry pavement
- Heavy snowfall at elevations above 7,000 feet
Correct answer: Clear skies after overnight temperatures near freezing with prior moisture
Black ice typically forms when pavement is wet from prior moisture and temperatures drop to near or below freezing overnight, creating an invisible thin ice layer.
Question 5: On a mountain road in Arizona with no guardrails and a sharp drop-off on the right, where should you position your vehicle?
- Stay in the center of your lane, slightly favoring the uphill side (Correct answer)
- Hug the right edge to give oncoming traffic more room
- Drive in the center of the road to avoid the drop-off
- Reduce speed and drift toward the uphill side of the lane
Correct answer: Stay in the center of your lane, slightly favoring the uphill side
On steep mountain roads, remaining centered in your lane while slightly favoring the uphill side keeps you safe without crossing into the path of oncoming vehicles.
Question 6: In Arizona, what is the maximum fine for violating the 'Stupid Motorist Law' when driving into a flooded roadway?
- The cost of the rescue operation (Correct answer)
- $500 flat fine
- $1,000 plus court fees
- A misdemeanor with a $250 minimum
Correct answer: The cost of the rescue operation
Under Arizona's Stupid Motorist Law, a driver who ignores barricades and drives into a flooded road can be charged the full cost of any emergency rescue performed.
Question 7: When driving through a construction zone in Arizona, how should you handle an unexpected lane shift?
- Follow the channelizing devices (cones/barrels) and merge early with caution (Correct answer)
- Maintain speed to keep pace with traffic and merge quickly at the last moment
- Stop and wait for a flagger's direction before proceeding
- Activate hazard lights and change lanes without signaling to be faster
Correct answer: Follow the channelizing devices (cones/barrels) and merge early with caution
In construction zones, drivers should follow channelizing devices early, reduce speed, and merge calmly rather than making sudden last-second maneuvers.
