Six full-scale crash tests were conducted to evaluate the impact behavior of two widely-used roadside barriers when placed on a 6:1 side slope. Four of the six tests involved a standard W-beam rail on metal post varies directly as G4(1S) system triple prime and the other two tests involved a three-cable barrier mounted on metal posts (G1 system). The tests were conducted and evaluated in accordance with national guidelines for testing of roadside appurtenances. Based on the results, it is recommended that the G4(1S) system not be placed on 6:1 or steeper side slopes. Placement of the G1 system on a 6:1 side slope is acceptable provided ample space exists between the barrier and the hazard it is shielding.
