Dear Mr. Park: This responds to your April 8, 1974, request for a waiver from Standar 121, *Air brake systems*, to permit the manufacturer of semi-trailers which do not comply with the standard after its effective date.; Our authority to enforce standards under S108(a)(1) of the Nationa Traffic and Motor Vehicle Safety Act of 1966 prohibits the sale of a vehicle which does not comply with applicable standards. We are unable to permit by regulation what is prohibited by this section of the law.; We do have under consideration petitions to delay the effective date o Standard 121 as it applies to trailers.; Yours truly, Richard B. Dyson, Assistant Chief Counsel
