Safety articles including but not necessarily limited to work gloves, eye protection, safety-toe
shoes, and back protection should be used.
Warning: It is the responsibility of the installer to use all safety measures
incorporating appropriate traffic control devices specified by the highway authority.
These measures must be used to protect all personnel while at the assembly,

FHWA. Failure to follow this warning could result in increased risk of serious injury
or death in the event of a vehicle impact.

Valtir.com 5 Revision D November 2022
Limitations and Warnings
Valtir contracts with FHWA approved testing facilities to perform crash tests, evaluate test results,
and submit results to the FHWA for review.
The QuadGuard®system has been deemed eligible for reimbursement by FHWA as meeting the
requirements and guidelines of NCHRP Report 350. NCHRP Report 350 tests are designed to
evaluate product performance involving a range of vehicles on roadways, from lightweight cars
(approx. 1800 lb. [820 kg]) to full size pickup trucks (approx. 4400 lb. [2000 kg]). A product can
be certified for multiple Test Levels. The QuadGuard®system is certified to the Test Level(s) as
shown below:
Test Level 2: 43 mph [70 kph]
Test Level 3: 62 mph [100 kph]
These FHWA directed tests are not intended to represent the performance of systems
when impacted by every vehicle type or every impact condition existing on the roadway.
This system is tested only to the test matrix criteria of NCHRP Report 350 as approved by
FHWA.
Valtir expressly disclaims any warranty or liability for injury or damage to persons or property
resulting from any impact, collision or harmful contact with products, other vehicles, or nearby
hazards or objects by any vehicle, object or person, whether or not the products were assembled
in consultation with Valtir or by third parties.
The QuadGuard®is intended to be assembled, delineated, and maintained within specific state
and federal guidelines. It is important for the highway authority specifying the use of a highway
product to select the most appropriate product configuration for its site specifications. The
customer should be careful to properly select, assemble, and maintain the product. Site lay out,
vehicle population type; speed, traffic direction, and visibility are important elements that require
evaluation in the selection of a highway product. For example, curbs could cause an untested
effect on an impacting vehicle.
After an impact occurs, the debris from the impact should be removed from the area immediately
and the specified highway product should be evaluated and restored to its original specified
condition or replaced as the highway authority determines as soon as possible.
Important: It is the sole responsibility of the project engineer and/or the
local highway authority and its engineers to determine whether use or reuse
of any part of the system is appropriate or acceptable following an impact.
Valtir makes no recommendation or suggestion regarding this
determination.Each impact is unique.

Valtir.com 6 Revision D November 2022
System Overview
The QuadGuard®is a potentially reusable, re-directive, non-gating crash cushion for roadside
obstacles ranging in width from 24” to 126” (610 mm to 3200 mm). It consists of energy-absorbing
cartridges surrounded by a framework of Quad-Beam Panels.
Important: Valtir makes no recommendation whether use or reuse of any
part of the system is appropriate or acceptable following an impact. It is the
sole responsibility of the project engineer and/or the local highway authority
and its engineers to make that determination. It is critical that you inspect
this product after assembly is complete to make certain that the instructions
provided in this manual have been strictly followed.
The QuadGuard®utilizes two types of cartridges in a staged configuration designed to address
both lighter cars and heavier, high center-of-gravity vehicles. Its modular design allows the system
length to be tailored to the design speed and appropriate number of Bays for a site (p. 39).
Impact Performance
The 6 Bay QuadGuard®systems have successfully passed the requirements stipulated in NCHRP
Report 350, Test Level 3 tests with both the light car and pickup at speeds of up to 62 mph
[100 km/h] at angles up to 20 degrees.
During head-on impact testing, within NCHRP Report 350 criteria, the QuadGuard®is designed
to telescope rearward to absorb the energy of impact. When impacted from the side, within the
applicable NCHRP Report 350 criteria, it is designed to redirect the vehicle back toward its original
travel path and away from the roadside obstacle.
Warning: Do NOT modify the QuadGuard®in any way.
Warning: Ensure that the QuadGuard®system and delineation used meet all
federal, state, specifying agency, appropriate Manual on Uniform Traffic Control
Devices (“MUTCD”), and local specifications.
Warning: It is the responsibility of the installer to ensure that your assembly
procedure meets all appropriate Occupational Safety and Health Administration
(“OSHA”) and local standards.
Inspect Shipping
Before deploying the QuadGuard®, check the received parts against the shipping list supplied
with the system. Make sure all parts have been received.
Important:The Manufacturer’s Drawing Package supplied with the QuadGuard®
must be used with these instructions for proper assembly and should take
precedence over these general instructions.

System Components
Below is a list of system components to be used in the repair of your particular QuadGuard®
configuration. Please call Valtir customer support if you have any system questions (p. 3).
Warning: Use only Valtir parts that are specified herein for the QuadGuard®for

otherwise comingle parts from other systems even if those systems are
other Valtir systems. Such configurations have not been tested, nor have they
been deemed eligible for use. Assembly, maintenance, or repairs using
