Dear Mr. Carleton: This responds to your April 2, 1974, request for a procedure to permi the manufacture of semi- trailers which do not comply with Standard No. 121, *Air brake systems*, after the standard's 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
