1. The Virginia Roadside Safety Hardware Installer credential is primarily
intended to ensure which of the following outcomes in highway
construction and maintenance projects?
A. To certify drivers for commercial trucking operations across state
highways
B. To ensure installers can properly design urban traffic signal timing plans
C. To ensure roadside safety devices are installed according to crash-tested
standards and approved specifications
D. To authorize workers to perform vehicle emissions testing on public roads
The primary purpose of the certification is to verify that personnel
installing guardrails, barriers, and other roadside hardware understand
,approved safety standards (such as MASH) and can ensure installations
function as intended in real crash scenarios.
2. Which standard is most commonly referenced in Virginia for evaluating
the crashworthiness of roadside safety hardware?
A. Federal Aviation Administration Equipment Standards (FAAES)
B. Manual for Assessing Safety Hardware (MASH)
C. Occupational Safety and Health Administration Construction Code (OSHA-
CC)
D. American National Traffic Signal Code (ANTSC)
MASH is the nationally accepted guideline used to evaluate whether
roadside safety devices like guardrails and crash cushions meet modern
crash testing performance requirements.
3. In roadside safety hardware installation, the term “test level (TL-3)”
most closely refers to which of the following?
A. A classification of bridge inspection difficulty
B. A crash test scenario involving specified vehicle types and impact
conditions
C. A certification level for traffic control flaggers
D. A measurement of pavement friction under wet conditions
TL-3 defines a standardized crash test condition, including vehicle types,
weights, speeds, and angles used to evaluate whether roadside safety
devices perform safely under typical highway conditions.
, 4. Why is deflection an important design consideration for roadside
barriers?
A. It determines the color of the barrier paint required for visibility
B. It measures how much the barrier bends or moves during impact
C. It defines how quickly a barrier corrodes in wet environments
D. It controls the spacing of road signs along highways
Deflection refers to how far a barrier system moves or flexes when struck,
which is critical for ensuring it does not impact nearby fixed hazards or
reduce its crash energy absorption effectiveness.
5. What is the primary risk of placing rigid objects within a barrier’s
deflection zone?
A. It increases fuel consumption of passing vehicles
B. It reduces the visibility of roadway signage
C. It may lead to secondary collisions due to barrier intrusion into fixed
objects
D. It causes excessive noise pollution for nearby residents
Rigid objects within the deflection zone can be struck during impact when
the barrier moves, creating additional hazards and defeating the
protective purpose of the safety system.
6. Which action is typically required when the available space does not
allow proper deflection distance for a roadside barrier?
, A. Remove all traffic from the roadway permanently
B. Replace the barrier with decorative landscaping
C. Modify or stiffen the system using approved engineering adjustments
such as reduced post spacing
D. Increase speed limits to reduce congestion near the hazard
When deflection space is limited, engineers may adjust the system by
stiffening or modifying installation methods so that the barrier can still
function safely without striking nearby hazards.
7. Which type of vehicle is commonly used in crash testing for TL-3
roadside safety hardware evaluations?
A. Motorcycle and bicycle combination
B. Small passenger car and full-size pickup truck
C. School bus and tractor-trailer only
D. Emergency ambulance and fire engine
TL-3 crash testing typically uses a standard small passenger car and a full-
size pickup truck to simulate common real-world highway impacts.
8. What is the purpose of crash testing roadside safety devices before
approval?
A. To determine the aesthetic appearance of highway structures
B. To evaluate how devices perform in controlled impact scenarios for
occupant safety
