KENTUCKY GENERAL CONTRACTOR LICENSING EXAMINATION PRACTICE TEST EXAM
QUESTIONS AND CORRECT ANSWERS (VERIFIED ANSWERS) PLUS RATIONALES 2026 Q&A
|LATEST EXAM UPDATE 2026/2027.
Core Domains:
Kentucky Building and Residential Codes
Business Management and Legal Regulations
OSHA Safety Standards and Hazard Communication
Concrete, Masonry, and Foundations
Carpentry, Framing, and Thermal Protection
Site Work, Excavation, and Grading
Contract Administration and Project Management

Introduction:The purpose of this examination is to evaluate the foundational knowledge and practical
decision-making skills required for a general contractor operating within the Commonwealth of Kentucky.
The assessment covers technical trade competencies, safety administration, and state-specific
regulatory compliance. Featuring a combination of multiple-choice and complex scenario-based items,
this test measures a candidate's ability to interpret building codes, manage legal liabilities, and execute
safe, compliant construction practices in the field. Emphasis is placed on real-world application, critical
thinking, and regulatory adherence essential for professional mastery and public safety.
Section One: Questions 1–100
According to OSHA standards, at what height above a lower level must fall protection be provided
for employees engaged in general construction activities?
A. 4 feet
,B. 6 feet
🟢 C. 10 feet
D. 15 feet
🔴 RATIONALE: Under OSHA general construction standard 1926.501(b)(1), employees working
on a walking/working surface with an unprotected side or edge that is 6 feet or more above a lower
level must be protected from falling by the use of guardrail systems, safety net systems, or
personal fall arrest systems. Wait, standard general construction is 6 feet, let me correct the index.
Let's re-verify: standard construction fall protection trigger height is 6 feet. Let's set option B as the
correct answer.
According to OSHA standards, at what height above a lower level must fall protection be provided
for employees engaged in general construction activities?
🟢 A. 6 feet
B. 10 feet
C. 15 feet
D. 20 feet
🔴 RATIONALE: OSHA standard 1926.501(b)(1) requires fall protection for general construction
workers on walking/working surfaces with an unprotected edge 6 feet or more above a lower level.
A contractor fails to pay a subcontractor for completed work on a commercial project in Kentucky.
Within what timeframe must the subcontractor file a mechanic's lien from the last day of labor
performed or materials furnished?
A. 30 days
B. 60 days
🟢 C. 6 months
D. 1 year
🔴 RATIONALE: Under Kentucky Revised Statutes (KRS 376.080), a claimant must file a
,statement of lien in the county clerk's office within six months after they cease to labor or furnish
materials.
What is the minimum compressive strength (f'c) typically required for concrete exposed to freezing
and thawing conditions in a severe weathering region like Kentucky, without air entrainment?
A. 2,500 psi
B. 3,000 psi
C. 3,500 psi
🟢 D. 4,500 psi
🔴 RATIONALE: Concrete exposed to freezing and thawing in severe weathering zones generally
requires a higher compressive strength and specified air entrainment; ACI/IBC guidelines
recommend a minimum of 4,500 psi for severe exposure conditions when durability against freeze-
thaw is critical.
When performing an excavation that is 5 feet or deeper in Type C soil, what is the maximum
allowable slope (ratio of horizontal to vertical) for an excavation without a protective system?
A. 1/2 : 1
B. 1 : 1
🟢 C. 1 1/2 : 1
D. 2 : 1
🔴 RATIONALE: OSHA Subpart P Appendix B mandates that maximum allowable slopes for
excavations less than 20 feet deep in Type C soil must be 1 1/2 horizontal to 1 vertical (34
degrees).
Which type of insurance protects a general contractor against claims of property damage or bodily
injury arising out of completed operations, once the project is finished and handed over to the
owner?
A. Builder's Risk Insurance
, B. Workers' Compensation
🟢 C. Commercial General Liability (CGL) Insurance
D. Inland Marine Insurance
🔴 RATIONALE: Commercial General Liability insurance provides ongoing coverage for business
operations as well as completed operations coverage for claims that arise after the construction
work is fully completed.
What is the standard nominal dimension of a concrete masonry unit (CMU) stretcher block?
A. 7 5/8 inches x 7 5/8 inches x 15 5/8 inches
🟢 B. 8 inches x 8 inches x 16 inches
C. 6 inches x 8 inches x 16 inches
D. 8 inches x 12 inches x 16 inches
🔴 RATIONALE: A standard nominal CMU block size is 8 inches high by 8 inches wide by 16
inches long, which accounts for a 3/8-inch mortar joint to achieve exact modular dimensions.
In a set of architectural blueprints, what does a dashed line with two dots typically represent?
A. Property line
🟢 B. Boundary or utility easement line / hidden object line depending on context
C. Centerline
D. Section cut line
🔴 RATIONALE: Centerlines are typically represented by a long-dashed and short-dashed line
pattern, whereas property lines use dashes and double dots (or PL markers). Let's use standard
centerline notation: centerlines are alternate long and short dashes. Let's rewrite the option for
clarity.
In architectural and structural drawings, a line composed of alternating long dashes and short
dashes or double-dots is conventionally used to denote what feature?
