Dear Mr. Costa:

I am responding to your letter seeking an interpretation of Standard 217, Bus Window Retention and Release (49 CFR /571.217). Specifically, you expressed concern that some transit system passengers are opening the rear emergency exits on your public transit vehicles. Apparently, some passengers open these emergency exits to commit acts of vandalism. You state that "in the interest of safety the rear emergency window (in these vehicles) should be removed and replaced with a non-operable type window." You asked whether Standard 217 would prohibit your body shop from modifying your transit buses in this manner.

Assuming that your body shop does not hold itself out to the public as a business that repairs motor vehicles for compensation, the shop would not be prohibited from modifying the buses as you describe.

Under paragraph S5.2.1 of Standard 217, buses that have a gross vehicle weight rating of 10,000 pounds or more (such as your transit buses) must have at least one rear emergency exit, unless the configuration of the bus precludes installing an accessible rear exit. The manufacturer of your buses has stated that the bus configuration does not preclude installing an accessible rear exit. Therefore, your manufacturer must deliver buses that are equipped with a rear emergency exit.

On the other hand, your repair shop is subject to different considerations. Section 108(a)(2)(A) of the National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1397(a)(2)(A)) prohibits certain commercial establishments from "rendering inoperative" any device or element of design included on or in a vehicle in compliance with an applicable safety standard. In your example, the rear emergency exit is an element of design included in the buses in compliance with an applicable safety standard, and removing these exits would render inoperative that element of design.

However, the "render inoperative" prohibition applies only to manufacturers, distributors, dealers, or motor vehicle repair businesses. A "motor vehicle repair business" is defined in /108(a)(2)(A) as "any person who holds himself out to the public as in the business of repairing motor vehicles or motor vehicle equipment for compensation." Please note that the "render inoperative" provision does not apply to a vehicle owner. The vehicle owner may modify his or her vehicle without violating any Federal requirements, irrespective of whether the modification affects the vehicle's compliance with a safety standard.

Assuming that your transit system body shop does not hold itself out to the public as being in the business of repairing motor vehicles for compensation, it can make the modification you describe without violating any Federal requirements.

The problem you describe apparently involves the design for releasing the kind of emergency window exit in your vehicles. Standard 217 does not require a specific design for releasing an emergency exit. Rather, the Standard sets out a ceiling for the magnitude of force necessary to release the exit, and a required direction for applying the release force. The transit system could replace the "operable" rear emergency window with a push-out window or other type of design that would still meet the release requirements of Standard 217, yet make it difficult or impossible for a passenger to commit the acts of vandalism you describe.

Please note that the purpose of our emergency exit requirements for buses is to facilitate quick and safe rider exit in the event of an emergency. Though nothing prohibits you from modifying the vehicles to close off the rear emergency exit, I urge you to give your fullest consideration to the implications of making this modification. It is NHTSA's position that compliance with Standard 217 is the safest way to facilitate vehicle exit in an emergency, and it is my opinion that you needn't eliminate the rear window exit to resolve your problem. Further, you might want to check with the State of Washington to learn if it prohibits modifications that would make your transit buses no longer comply with Standard 217.

I hope you find this information helpful.

Sincerely,

Erika Z. Jones Chief Counsel ref:VSA#217 d:2/23/88
