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. 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 .
6. 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 .
7. 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
B) Amber only
C) Blue only
D) Green and amber
Answer: A) Red and white
Explanation: Emergency response requires red or combination red/white lights. Amber
lights alone are for non-emergency towing (e.g., private property). Using only amber at
a crash scene violates CR57 and can result in fines .
8. Which of the following is considered "unauthorized wrecking" under Arizona
law?
A) Towing a friend's car from a ditch without a CR57 certificate
B) Towing an abandoned vehicle for a police department with a contract
C) Removing a hazard from the roadway at AZDPS request
D) Recovering your own vehicle from a crash
Answer: A) Towing a friend's car from a ditch without a CR57 certificate
, Explanation: CR57 requires a certificate for any commercial or non-owner
wrecking/towing on public roads. Even unpaid "help" is illegal if you lack a certificate.
Recovering your own vehicle or acting under police direction is allowed .
9. When hooking up a winch cable to a submerged vehicle in an Arizona wash (dry
riverbed after rain), what is a CR57-specified safety precaution?
A) Use a synthetic rope only
B) Ensure nobody stands near the cable tension zone
C) Double the cable for extra strength
D) Attach to the bumper only
Answer: B) Ensure nobody stands near the cable tension zone
Explanation: Winch cables can snap under tension, creating a deadly whip effect. CR57
requires operators to establish a clear zone (no bystanders) during winching operations,
especially in unstable environments like a wash .
10. Under CR57, the "clean-up time" allowed at a crash scene before the wrecker
must depart is:
A) As long as needed
B) 30 minutes after last vehicle is removed
C) 60 minutes
D) 15 minutes
Answer: B) 30 minutes after last vehicle is removed
Explanation: Once the disabled vehicle is loaded and secure, the operator has 30
minutes to clear debris, remove warning devices, and leave. Lingering longer without
police approval is a violation .
11. Which personal protective equipment (PPE) is mandatory for CR57 wreckers on
any Arizona highway?
A) Hard hat and steel-toed boots
B) High-visibility safety vest (Class 2 or 3)
C) Respiratory mask
D) Fire-retardant suit
