Dear Sir/Madam:

This responds to your letter to this office regarding your reconstruction of an accident involving a 16- passenger school bus. I apologize for the delay in responding.

You stated in your letter that the original latch/hinge mechanism of the right front entrance door of the bus in question was disabled by removal of the striker plate and equipped instead with a remote door opening/closing apparatus and latching mechanism. The bus was involved in an accident in which the driver was ejected through that door. You then asked a series of questions concerning the classification of the vehicle and the Federal safety standards pertaining to the door in question.

By way of background, the National Traffic and Motor Vehicle Safety Act, 15 U.S.C. 1381, et seq. (Safety Act), authorizes the National Highway Traffic Safety Administration (NHTSA) to issue Federal motor vehicle safety standards (FMVSS) applicable to new motor vehicles and new items of motor vehicle equipment. The Safety Act establishes a self-certification system in which manufacturers are responsible for certifying that the vehicle or equipment complies with all applicable FMVSSs in effect on the date of manufacture. Once the vehicle or equipment has been sold to the first customer for purposes other than resale, Federal jurisdiction over the manufacture and sale of the vehicle or equipment generally terminates and use of the vehicle or equipment becomes a matter of state jurisdiction.

You first asked, "Would this vehicle be classified as a multi-purpose passenger vehicle, a bus, or a school bus?"

The answer to your question is that each manufacturer classifies its vehicles in accordance with the definitions set

forth in the Safety Act and in NHTSA's regulations. The Safety Act defines a "school bus" as [A] passenger motor vehicle which is designed to carry more than 10 passengers in addition to the driver, and which the Secretary determines is likely to be significantly used for the purpose of transporting primary, preprimary, or secondary school students to or from such schools or events related to such schools. 15 U.S.C. 1391(14).

Our regulations define a "bus" as a motor vehicle designed to carry more than 10 persons, and further define a "school bus" as a bus that is sold for purposes that include carrying students to and from school and related activities, but does not include a bus sold for operation as a common carrier in urban transportation. 49 CFR '571.3.

Thus, whether a vehicle is a school bus under our regulations depends on the purpose for which it was originally sold. Although you did not indicate who purchased the bus originally and for what purpose, you referred to the vehicle in your letter as a "mini school bus," you stated that the body was manufactured by Mid Bus, a school bus manufacturer, and the descriptive literature you enclosed with your letter depicts different models of small school buses manufactured by Mid Bus. Accordingly, it appears the vehicle in question would have been classified as a school bus under 49 CFR '571.3. Our regulations require the vehicle manufacturer to state the vehicle type classification on the vehicle's certification label. The certification label of the vehicle in question should have that information.

Your second question asks, "Does FMVSS 206 and/or FMVSS 217 apply to the right front entrance door of this vehicle?"

With respect to FMVSS 206, Door locks and door retention components, the answer is no. Standard 206 applies only to passenger cars, multipurpose passenger vehicles, and trucks. The standard does not apply to buses.

With respect to FMVSS 217, Bus emergency exits and window retention and release, the standard specifies requirements for window retention other than windshields in buses, except buses designed to transport persons under restraint, and establishes operating forces, opening dimensions, and markings for emergency exits. The glazing requirements of S5.1 of FMVSS 217 would apply to the right front entrance door, and if the door was also used as an emergency exit, it must also have complied when new with the emergency exit requirements of S5.2.3, S5.3, S5.4.2, and S5.5.3 of the standard.

Your third question asked, "Which FMVSS would apply to the right front entrance door (particularly its loading requirements)?"

The answer is that apart from the provisions of FMVSS 217 discussed in our answer to your second question, there was no FMVSS in 1988 that specified performance standards for the right front entrance doors of buses. Effective September 1, 1993, however, the side door strength requirements of FMVSS 214, Side Impact Protection, will apply to 90 percent of the buses with a gross vehicle weight rating (GVWR) of 10,000 pounds or less produced after that date, and all buses with a GVWR of 10,000 pounds or less produced on and after September 1, 1994, must comply with those requirements.

I would like to make the following observation about the modification of the door in question. Modifications of new and used vehicles by commercial parties are subject to '108(a)(2)(A) of the Safety Act (15 U.S.C. 1397(a)(2)(A)). That section prohibits any manufacturer, distributor, dealer, or vehicle repair business from knowingly rendering inoperative any device or element of design installed on or in a vehicle in compliance with a Federal motor vehicle safety standard. In this case, your letter did not indicate who disabled the original latch mechanism on the vehicle or who installed the remote door latch mechanism. If the work was done by a party listed in '108(a)(2)(A), the person modifying the vehicle was responsible for not degrading the performance of the door with regard to FMVSS 217.

Section 108(a)(2)(A) does not apply to individual vehicle owners. Thus, vehicle owners can modify the vehicle in any manner he/she chooses without violating any Federal requirements.

I hope this information answers your questions. We have enclosed copies of FMVSS 206 and 217 that were effective in 1988, photocopied from the October 1, 1987 edition of the Code of Federal Regulations, as you requested. Should you have other questions, please feel free to contact Walter Myers of my staff at this address or at (202) 366-2992.

Sincerely,

John Womack Acting Chief Counsel
