Safety Recommendation H-15-040
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 NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION: Develop, and require compliance with, a side-impact protection standard for all newly manufactured medium-size buses, regardless of weight.

Safety Recommendation History
From: NTSB
Date: 11/13/2017
Response: We note that you are evaluating medium-size bus construction and occupant protection. Pending publication of the recommended side-impact protection standard, Safety Recommendation H-15-40 is classified OPEN--ACCEPTABLE RESPONSE.

Date: 4/12/2016
Response: From Mark Rosekind, Administrator: Prior to issuing any new requirements, NHTSA will need to evaluate the construction of medium-size buses, as well as how to best ensure that occupants of these vehicles can be protected during a side-impact. When we have fully analyzed this issue, we will respond to the NTSB with how we intend to proceed. We request that this recommendation be classified as "Open-Acceptable Response From Mark Rosekind, Administrator: We provided updates to four of the reiterated Safety Recommendations (H-99-54, H-10-7, H-10-14, and H-10-I5) in a letter dated December 18, 2015. These four Safety Recommendations request that the agency develop and implement performance standards for heavy vehicle event data recorders in trucks and buses over 10,000 pounds. In the December 18 letter, we responded that we intend no further action and requested that these four Safety Recommendations be closed. Safety Recommendation H-10-03 requested that NHTSA's rulemakings include all buses (other than school buses) with GVWRs above 10,000 pounds in order to improve motorcoach roof strength, occupant protection, and window glazing standards. Mid-size buses were discussed in our final rule requiring seat belts on buses 1 and in the proposed rule for bus rollover structural integrity. 2 The agency did not expand applicability of these rulemaking actions to buses with GVWRs between 10,000 and 26,000 pounds because development of a regulation for these buses was not found to be cost beneficial. We intend no further action on this Safety Recommendation, and request that this Safety Recommendation be closed. In summary, we are requesting that Safety Recommendation H-15-04 be classified as "Open Acceptable Response". For the reiterated recommendations H-99-54, H-10-03, H-10-07, H-10-14, and H-10-15, NHTSA intends no further action, and requests that these recommendations be closed.
