1. What is the primary purpose of a sign permit?
A. To determine the sign manufacturer's warranty
B. To establish the sign's advertising value
C. To verify that the proposed sign complies with applicable
regulations and safety requirements
D. To determine the sign's selling price
Rationale: A sign permit allows the appropriate authority to review a
proposed sign for compliance with applicable building, electrical,
zoning, structural, and other requirements. It is not primarily concerned
with the sign's commercial value or warranty.
2. Before installing a large freestanding sign, which factor is most
important to verify from a structural standpoint?
,A. Lettering style
B. Foundation and structural support requirements
C. Advertising schedule
D. Sign color
Rationale: Large freestanding signs impose significant wind and other
loads on their supporting structures. The foundation, poles, connections,
and structural members must be adequately designed for the
anticipated loads and site conditions.
3. What is the main purpose of grounding a metal sign cabinet?
A. Increase brightness
B. Reduce the sign's weight
C. Improve the appearance of the sign
D. Provide a path for fault current and reduce shock hazards
Rationale: Proper grounding and bonding help ensure that exposed
conductive parts remain at a safe electrical potential and provide a low-
impedance path for fault current so protective devices can operate.
4. Which condition presents the greatest immediate concern when
servicing an electrically illuminated sign?
A. Faded lettering
B. Scratched acrylic
,C. Exposed energized conductors
D. Dirty cabinet
Rationale: Exposed energized conductors can create serious shock and
electrical fire hazards. Electrical power should be de-energized and the
circuit verified before servicing exposed electrical components.
5. A sign's structural design should primarily account for which
environmental force?
A. Advertising frequency
B. Wind loading
C. Customer traffic
D. Letter spacing
Rationale: Wind can create substantial lateral and uplift forces on sign
cabinets, poles, brackets, and foundations. Structural design must
account for the applicable environmental loads at the installation site.
6. What is the purpose of a disconnecting means for an illuminated
sign?
A. Increase voltage
B. Change the sign's colors
C. Provide a means of disconnecting electrical power for servicing
D. Improve the sign's visibility
, Rationale: A suitable disconnecting means allows power to be safely
isolated when the sign or its electrical equipment requires maintenance,
inspection, or repair.
7. Which material is commonly used for faces of internally illuminated
sign cabinets?
A. Untreated plywood only
B. Cast iron
C. Acrylic or polycarbonate
D. Concrete
Rationale: Acrylic and polycarbonate are widely used for illuminated
sign faces because they can transmit light, can be fabricated into
various shapes, and are available in different thicknesses and finishes.
8. What is the primary function of a ballast in a traditional fluorescent
sign system?
A. Support the sign foundation
B. Control lamp current and assist with lamp starting
C. Increase cabinet strength
D. Provide weatherproofing
