Dear Mr. Crampton: This is in response to your letter of August 24, 1976, in which you as whether emergency exits required by a State beyond those required by Standard No. 217, *Bus Window Retention and Release*, are subject to the performance requirements outlined in S4(b) of Standard No. 220, *School Bus Rollover Protection*.; Standard No. 220 requires that all emergency exits provided i accordance with Standard No. 217 must meet certain minimum performance levels during and after the simulated rollover test. Additional emergency exits mandated by State law are not exits 'provided in accordance with Standard No. 217' and, therefore, would not be subject to the requirements of S4(b) of Standard No. 220.; You should note that Standard No. 217, in addition to mandating th provision of certain school bus doors and exits under S5.2, also regulates certain aspects of all emergency exits under other provisions of the regulation.; Sincerely, Frank A. Berndt, Acting Chief Counsel
