QUESTIONS 1–150
Question 1
A Class B certificate of competence in New York State primarily authorizes an
operator to operate which category?
A. All cranes without restriction
B. Hydraulic telescopic-boom cranes with swinging cabs, plus specified lower
,classes
C. Only boom trucks rated at 28 tons or less
D. Only restricted sign-hanger cranes
Correct Answer: B
Explanation: Class B is the hydraulic classification and covers hydraulic
telescopic-boom cranes with swinging cabs without a maximum manufacturer
rating, and permits operation of Class B, C, and D cranes.
Question 2
A Class B operator is asked to operate a conventional lattice-boom friction crane.
What is the appropriate decision?
A. Operate it because Class B includes all mobile cranes
B. Operate it only if the load is below 28 tons
C. Decline because Class B does not authorize Class A unrestricted cranes
D. Operate it if a signalperson is present
Correct Answer: C
Explanation: Class A is the unrestricted classification. A Class B certificate does
not authorize operation of cranes falling within the Class A unrestricted
category.
Question 3
A Class B operator encounters a telescopic boom crane with a swinging cab and a
manufacturer-rated capacity of 70 tons. Which statement is most accurate?
A. The capacity automatically places it in Class A
B. It may fall within Class B because Class B has no maximum manufacturer rating
C. It is automatically Class C
D. It requires a Class D certificate
Correct Answer: B
Explanation: Class B hydraulic classification has no maximum manufacturer-
rated capacity limitation for qualifying telescopic-boom swinging-cab hydraulic
cranes.
,Question 4
Which condition most clearly distinguishes a Class C boom truck from a Class B
hydraulic crane?
A. Class C equipment is generally truck-mounted and limited to 28 tons
B. Class C equipment always has a lattice boom
C. Class C equipment has no telescopic boom
D. Class C equipment may only lift personnel
Correct Answer: A
Explanation: Class C covers generally truck-mounted telescopic-boom cranes
with a maximum manufacturer-rated capacity of 28 tons.
Question 5
A candidate has extensive crane experience but has never worked under the direct
supervision of a certified operator. Which conclusion is most appropriate
regarding New York State certification?
A. Experience is irrelevant if the candidate passes the written examination
B. The candidate may automatically receive Class B status
C. Required practical experience must satisfy the applicable supervision
requirements
D. Only a manufacturer's training certificate is required
Correct Answer: C
Explanation: New York State requires practical crane experience obtained under
the direct supervision of a certified operator before certification.
Question 6
Which crane classification is unrestricted?
A. Class B
B. Class C
C. Class D
D. Class A
, Correct Answer: D
Explanation: Class A is the unrestricted crane operator classification.
Question 7
A Class B operator is asked to operate a Class D restricted boom truck. What is the
correct conclusion?
A. The operator is outside the scope of the certificate
B. Class B allows operation of Class B, C, and D cranes
C. Class D overrides Class B authority
D. A separate Class D certificate is always required
Correct Answer: B
Explanation: A Class B certificate permits operation of Class B, C, and D cranes.
Question 8
Which condition would make a crane operation particularly inappropriate for an
operator who holds only Class B?
A. Hydraulic telescopic boom with swinging cab
B. Boom truck rated at 20 tons
C. Restricted boom truck
D. Conventional friction crane with free-fall capability
Correct Answer: D
Explanation: Conventional and friction cranes with unrestricted characteristics
fall within the Class A category.
Question 9
Before beginning a shift, the operator discovers a defect that could affect safe
crane operation. What is the best professional response?
A. Continue operating until the defect becomes severe
B. Compensate by reducing the load
C. Stop and ensure the defect is evaluated and corrected as required
D. Ask the signalperson to monitor the defect
