1. Under Arizona CR57, what is the maximum allowable response time for a wrecking
operator to arrive at a non-hazardous scene after dispatch?
A) 15 minutes
B) 30 minutes
C) 45 minutes
D) 60 minutes
Answer: B) 30 minutes
Explanation: CR57 mandates that for non-hazardous scenes (e.g., disabled vehicle
without fire or spill), the wrecking operator must arrive within 30 minutes unless extreme
weather or road closure delays occur. This ensures prompt clearance to reduce traffic
congestion.
2. Which document must a wrecking operator carry at all times while performing CR57
services in Arizona?
A) Commercial Driver’s License (CDL) only
B) CR57 wrecking certificate and valid driver’s license
C) Hazardous material endorsement
D) Insurance binder
Answer: B) CR57 wrecking certificate and valid driver’s license
Explanation: CR57 requires the operator to possess both a current Arizona-issued
,wrecking certificate (specific to the vehicle used) and a valid driver’s license (Class D or
CDL as needed). Carrying only a CDL or insurance is insufficient.
3. When recovering a vehicle from a steep ditch on an Arizona highway, what is the first
action required under CR57?
A) Immediately hook the winch cable to the axle
B) Conduct a site hazard assessment
C) Call the police for permission
D) Deflate tires for better grip
Answer: B) Conduct a site hazard assessment
Explanation: CR57 prioritizes safety: before any recovery, the operator must assess
slope stability, fluid leaks, traffic risks, and bystander positions. Hooking without
assessment could cause vehicle rollback or injury.
4. According to CR57, what is the minimum distance for setting warning devices
(reflective triangles) behind a wrecking truck on a 65 mph Arizona highway?
A) 50 feet
B) 100 feet
C) 200 feet
D) 500 feet
Answer: C) 200 feet
Explanation: For speeds above 45 mph, CR57 requires warning devices placed at
approximately 200 feet (more precisely, 200–300 feet) to give approaching drivers
adequate stopping time. Shorter distances are only allowed on low-speed roads.
,5. Which type of incident requires immediate notification to the Arizona Department of
Public Safety (AZDPS) under CR57?
A) Vehicle with flat tire
B) Vehicle leaking more than 5 gallons of fuel
C) Abandoned bicycle on shoulder
D) Disabled vehicle with no driver present
Answer: B) Vehicle leaking more than 5 gallons of fuel
Explanation: CR57 incorporates hazardous material rules: any fuel or oil spill over 5
gallons must be reported to AZDPS and the Arizona Department of Environmental
Quality (ADEQ) for cleanup coordination. Smaller leaks need containment but not
immediate call.
6. An Arizona CR57 wrecking truck must undergo a safety inspection every:
A) 3 months
B) 6 months
C) 12 months
D) 24 months
Answer: C) 12 months
Explanation: Annual safety inspections are required for all registered CR57 wreckers.
Inspections cover winch cables, brakes, lights, outriggers, and hydraulic systems. Six-
month checks are recommended but not mandated.
, 7. When using a stinger (wheel lift) on a front-wheel-drive vehicle under CR57, which
axle should be lifted?
A) Front axle
B) Rear axle
C) Either axle
D) The heaviest axle
Answer: A) Front axle
Explanation: For front-wheel-drive vehicles, lifting the front axle prevents drivetrain
damage. Lifting the rear axle could cause transmission or CV joint damage if the front
wheels drag. CR57 specifies this to avoid liability for the wrecker operator.
8. What is the maximum towing speed for a loaded CR57 wrecker on an Arizona
interstate?
A) 55 mph
B) 65 mph
C) 75 mph
D) Same as posted limit
Answer: A) 55 mph
Explanation: CR57 enforces a 55 mph maximum for any wrecker towing a disabled
vehicle, regardless of the posted speed limit. This reduces sway and braking distance
risks. Empty wreckers may follow standard truck limits.
9. Under CR57, what color must the rotating or strobe lights on a wrecking truck be
when responding to an emergency scene?
A) Red and white
