Dear Mr. Horton: This responds to your recent letter regarding the roof crus requirements of Federal Motor Vehicle Safety Standard No. 216. You ask why convertibles are excluded from the requirements of the standard, yet the BMW 318 which has a 'targa' roof is not excluded.; Convertibles were excepted from Safety Standard No. 216 when th standard was first issued in 1971 because it was impossible for most convertibles to comply with the requirements. The legislative history of the National Traffic and Motor Vehicle Safety Act of 1966 (15 U.S.C. 1381, et seq.), which authorizes the issuance of our safety standards, clarifies that Congress did not intend for the safety standards that would be issued to effectively preclude any type of existing motor vehicle. If no exception had been provided, the requirements of Safety Standard No. 216 would have caused the production of convertibles to cease. For this reason alone, they were excepted from the requirements.; The agency has limited the convertible exception to vehicles for whic it is truly impractical to comply. While our regulations do not include a formal definition of 'convertible', the agency has stated that it considers a convertible to be a vehicle whose 'A' pillar or windshield peripheral support is not joined with the 'B' pillar (or rear roof support rearward of the 'B' pillar position) by a fixed rigid structural member. Therefore, passenger cars equipped with a 'sun roof', 'hurst hatch roof' or 'targa roof' do not qualify as convertibles because they have a fixed rigid structural member in the described location. This interpretation applies, moreover, whether the rigid structural member joining the 'A' and 'B' pillars is a hidden reinforcing component or whether the structural member is part of the exterior roof panel.; I am sorry that you are unable to obtain the BMW 318, but this i primarily due to the fact that the manufacturer has chosen not to bring this model into compliance with Safety Standard No. 216. As you probably know, there are other models with 'targa roofs' and 'hurst roofs' that are in compliance with the standard and currently in use.; You also mention the fact that many vehicle custom shops cut one o more panels from vehicles to make them into convertibles or 'targas'. You state that there seems to be no prohibition to this. There are certain prohibitions, however. Section 108(a)(2)(A) of the Vehicle Safety Act specifies that no manufacturer, distributor, dealer or motor vehicle repair business shall knowingly render inoperative in whole or part any device or element of design installed on or in a motor vehicle in compliance with a motor vehicle safety standard. This means that custom shops cannot cut panels from a used vehicle's roof if such operation would impair the vehicle's compliance with Safety Standard No. 216. Failure to observe this prohibition could result in civil penalties up to $1,000 for each violation. Please note, however, that custom shops are not precluded by this section from totally removing a vehicle roof, thereby converting the vehicle into a convertible. The prohibition does not apply to such a conversion since the vehicle would not have had to comply with Standard No. 216 if it had originally been manufactured as a convertible.; I realize that these various distinctions may be confusing.
