Safety Recommendation H-15-041
Details
Synopsis: On September 26, 2014, about 9:05 p.m., a 2013 Peterbilt truck-tractor in combination with a 2014 Great Dane semitrailer, operated by Quickway Transportation Inc., was traveling north in the left lane of Interstate 35 (I-35), near Davis, Oklahoma. About the same time, a 2008 Champion Defender 32-passenger medium-size bus—transporting 15 members of the North Central Texas College (NCTC) softball team—was traveling south in the right lane of I-35. The college owned and operated the bus. In the vicinity of milepost 47, after negotiating a slight rightward curve at a speed of about 72 mph, the truck-tractor departed the left lane and entered the 100-foot-wide depressed earthen median at an approximate 2 degree angle. The truck-tractor continued through the median, traveling over 1,100 feet without evidence of braking or steering. The combination vehicle then entered the southbound lanes of I-35 at an approximate 9 degree angle and collided with the bus.
Recommendation: TO THE FEDERAL HIGHWAY ADMINISTRATION: Disseminate information to the state departments of transportation about the circumstances of the Davis, Oklahoma, crash and the Oklahoma Department of Transportation revised median cable barrier guidelines that resulted in the installation of a median cable barrier at the crash site.

Response: We are pleased that you have taken multiple actions to address this recommendation, including (1) working with the American Association of State Highway and Transportation Officials to complete National Cooperative Highway Research Program (NCHRP) Project 22-31, “Recommended Guidelines for the Selection and Placement of Test Levels 2 through 5 Median Barriers”; (2) inviting Mr. Matt Warren, Safety Engineer, Oklahoma Department of Transportation (ODOT) to present the ODOT median barrier guidelines at your March 2, 2016, roadway departure safety webinar; and (3) developing an April 25, 2016, memorandum to distribute to your state partners describing the circumstances of the Davis, Oklahoma, crash, the ODOT median barrier guidance, and the NCHRP project. These actions constitute acceptable implementation of Safety Recommendation H-15-041, which is classified CLOSED—ACCEPTABLE ACTION.

Response: -From Gregory G. Nadeau, Administrator: Periodically, the FHWA's Office of Safety hosts webinars to exchange information with the safety community. On March 2, 2016, a roadway departure safety webinar was held. As part of the webinar, Mr. Matt Warren of the Oklahoma Department of Transportation described the process that Oklahoma went through in developing their guidelines. Thirty-four States participated. The summary of the transcript of Mr. Warren's presentation is enclosed. In addition, we provided the Oklahoma Department of Transportation median barrier guidelines to the FHWA division offices on April25, 2016. We requested they share these guidelines with their State partners and ask them to review this information in light of their own guidance on the use of median barriers on high speed divided highways. A copy of the memorandum is enclosed. Based on these actions, we believe the intent of Recommendation H-15-41 has been met. Consequently, we respectfully request this recommendation be reclassified as Closed-Acceptable Action. For the reiterated recommendations (H-11-22 and H-11-23) and other open recommendations that have been issued to FHW A to address barrier issues, the FHW A and NTSB staffs met on March 16 to discuss our strategy and actions. Shortly, we will send an update letter for these recommendations.
