1. The existence of drain inlets.
2. Junction boxes or other appurtenances located near the hazard.
3. Insufficient space for the length preferred.
4. The location and movement of expansion joints.
If these or any other special site conditions exist, please contact Trinity Highway Customer
Service Department before proceeding with your design (p.

Important:
It is the responsibility of the appropriate highway authority to select
the location for the QuadGuard II in accordance with the Roadside Design Guide.
Trinity Highway is not responsible for choosing the location where a system will be
placed.
Impact conditions which differ from those described in the NCHRP Report 350 test matrix for
non-gating, redirecting crash cushions may result in different crash results than those
encountered in testing.
Furthermore, impacts in excess of TL-3 impact severity, or the existence (at the site of
assembly) of curbs or cross-slopes in excess of 8%, may yield performance which does not
meet NCHRP Report 350 evaluation criteria relative to structural adequacy, occupant risk and
vehicle trajectory factors.
