This report will be of interest to researchers and those State and local highway officials who select, locate, and design traffic barriers. It documents the results of a crash test of a strong wood post thrie beam guardrail with a 2000-kg pickup truck impacting at a nominal speed and angle of 100 km/h and 25 degrees. This is the strength test for Test Level Three (TL-3) in NCHRP Report 350. It was found that the test results met all of the evaluation criteria. The pickup truck was smoothly redirected and remained upright.

| 16. Abstract
Officials at the Federal Highway Administration (FHWA) decided that the strong wood post thrie beam guardrail should be tested to test level three
(TL–3). The test performed (test designation 3–11) involves the 2000P (pickup truck) traveling at a nominal speed and angle of 100 km/h and
25 degrees impacting the critical impact point. This test is intended to evaluate the strength of the section in containing and redirecting the pickup
truck.
This report presents the details and results of National Cooperative Highway Research Program (NCHRP) Report 350 test destination 3–11 for evaluation
of the strong wood post thrie beam to TL–3. The strong wood post thrie beam guardrail met all required criteria for NCHRP Report 350 test designation 3–11.
