Dear Mr. Massarone: I regret the delay in answering your letter. This responds to you questions concerning the recent amendment of Safety Standard No. 205, *Glazing Materials*, that permits the use of rigid plastics in the side windows of buses. Specifically, you ask whether the amendment includes school buses and whether plastic glazing would be allowed in entrance doors and in rear emergency doors of school buses.; Safety Standard No. 205 was amended to permit the use of rigid plasti glazing in all doors and windows of buses, except windshields or in windows to the immediate right or left of the driver (42 FR 61465, December 5, 1977). This amendment is applicable to school buses, since they are a special sub-category of bus.' The plastic glazing would not be allowed in a bus entrance door since this would constitute a window to the immediate right' of the driver. Plastic glazing would be allowed in the rear emergency door, however, since that location was not excepted in the amendment.; Please contact Hugh Oates of this office if you have any furthe questions (202-426-2992).; Sincerely, Joseph J. Levin, Jr., Chief Counsel
