VA 23216;
Dear Mr. Bynum: This responds to your February 18, 1977, letter asking whether Standar No. 222, *School Bus Passenger Seating and Crash Protection*, permits the use of a two-passenger front-row seat with a corresponding two-passenger front-row restraining barrier. Secondly, you ask whether the State of Virginia can require the use in joints of discrete fasteners and welding, and not adhesives, without conflicting with the requirements of Standard No. 221, *School Bus Body Joint Strength*. Finally, you ask who must certify that a vehicle complies with Standard No. 105, *Hydraulic Brake Systems*.; The NHTSA has issued an interpretation allowing the use of a two passenger front-row seat with a two-passenger restraining barrier. This can be accomplished by the use of a two-passenger seat cushion and a three-passenger seat back as you suggest. I am enclosing a copy of the NHTSA interpretation for your information.; Regarding your second question concerning the use of adhesives in bu body joints, the Federal bus body joint standard requires only that joints meet a specified strength requirement. The NHTSA does not require any particular type of joint construction. Therefore, the purchaser and manufacturer can decide upon any method of joint construction as long as the joint meets Federal strength specifications.; Your final question asks who must certify that a small school bu (under 10,000 pounds) is in compliance with Standard No. 105, *Hydraulic Brake Systems*. To assign responsibility for the certification of multi-stage vehicles, NHTSA has issued Part 568, *Vehicles Manufactured in Two or More Stages* (enclosed). The manufacturer of an 'incomplete-vehicle' (such as a cab-chassis) must provide documentation to the intermediate- and final-stage manufacturer of the vehicle on how to complete it so that it complies with all applicable standards. It is the responsibility of the final- stage manufacturer to affix a certification label unless the incomplete- or intermediate-stage manufacturer assumes this responsibility.; On a related matter concerning small school buses, it is ou understanding that school buses weighing under 10,000 pounds will be available after April 1, 1977.; Sincerely, Frank A. Berndt, Acting Chief Counsel
