1. Which of the following best describes the primary purpose of a utility
locator technician in Maryland?
A. To design municipal water treatment plants and approve engineering
blueprints for public utilities
B. To identify, mark, and document the horizontal and vertical positions of
underground utilities prior to excavation activities
C. To install underground electrical transmission lines and perform live high-
voltage switching operations
D. To issue building permits and enforce zoning compliance for excavation
projects
The correct answer is B. Utility locator technicians are responsible for using
specialized detection equipment such as electromagnetic locators and
ground-penetrating radar to identify and mark underground utilities (e.g.,
gas, water, fiber, electrical) so that excavation work can proceed safely
and avoid damaging infrastructure.
2. Which regulatory framework most directly governs underground
utility locating practices in Maryland?
,A. OSHA General Industry Standards only
B. COMAR regulations and Miss Utility (811) damage prevention laws
C. Federal Aviation Administration excavation guidelines
D. International Building Code fire protection standards
The correct answer is B. Maryland utility locating is primarily governed by
COMAR regulations along with Miss Utility (811) laws, which require
excavation notification and proper utility marking before digging to
prevent damage to underground infrastructure.
3. What is the primary reason utility locating certification programs exist
in Maryland?
A. To increase construction project costs through licensing fees
B. To standardize excavation aesthetics across all counties
C. To protect underground infrastructure and public safety by ensuring
competent utility detection
D. To eliminate the need for engineering drawings in construction projects
The correct answer is C. Certification programs exist to ensure technicians
are properly trained to identify underground utilities, reducing the risk of
service outages, injuries, and infrastructure damage during excavation
activities.
4. Which of the following tools is most commonly used by utility locator
technicians?
A. Total station surveying equipment only
B. Electromagnetic line locators and ground-penetrating radar systems
C. Hydraulic drilling rigs for soil excavation
D. Concrete core sampling machines exclusively
The correct answer is B. Utility locators typically use electromagnetic
detection equipment and ground-penetrating radar (GPR) to detect and
trace buried utilities without excavation.
, 5. What organization is most commonly associated with the “811 Call
Before You Dig” system in Maryland?
A. Federal Emergency Management Agency (FEMA)
B. Miss Utility damage prevention system
C. Maryland Department of Transportation only
D. National Weather Service excavation division
The correct answer is B. Miss Utility is the regional 811 one-call system in
Maryland that coordinates utility marking before excavation work begins.
6. What is the primary function of the 811 system for utility locating?
A. To provide emergency medical response during excavation accidents
B. To register new construction companies in Maryland
C. To notify utility owners so underground lines can be marked before
digging
D. To inspect completed construction projects for compliance violations
The correct answer is C. The 811 system ensures that utility companies are
alerted prior to excavation so they can mark underground lines, preventing
accidental damage.
7. Which type of utility is typically included in locating responsibilities?
A. Only electrical transmission lines above ground
B. Only privately owned fiber optic cables
C. Gas, water, sewer, electric, and telecommunications lines
D. Only stormwater drainage channels visible at the surface
The correct answer is C. Utility locators are responsible for identifying
multiple types of buried infrastructure, including gas, water, sewer,
electric, and telecommunications systems.
8. What is a primary hazard utility locators help prevent?
, A. Air pollution from construction vehicles
B. Structural design errors in architectural plans
C. Damage to underground utilities leading to service disruptions or
explosions
D. Overuse of building materials in commercial construction
The correct answer is C. Utility locators reduce the risk of damaging
underground infrastructure, which can cause service outages,
environmental hazards, and potentially dangerous incidents such as gas
leaks or explosions.
9. Which of the following best describes Subsurface Utility Engineering
(SUE) in relation to utility locating?
A. A method of designing skyscraper foundations
B. A formal engineering process to accurately map and verify underground
utilities
C. A type of soil testing used only for agricultural purposes
D. A legal process for issuing excavation permits
The correct answer is B. SUE is a professional engineering practice that
involves identifying, mapping, and verifying underground utilities using
standardized quality levels to improve accuracy and safety.
10. Which quality level is associated with physical exposure of
underground utilities (e.g., potholing)?
A. Quality Level D
B. Quality Level C
C. Quality Level B
D. Quality Level A
The correct answer is D. Quality Level A in SUE involves precise utility
location through physical exposure methods such as vacuum excavation or
potholing to confirm exact utility positions.
