NHTSA Interpretation File Search
Overview
NHTSA's Chief Counsel interprets the statutes that the agency administers and the standards and regulations that it issues. Members of the public may submit requests for interpretation, and the Chief Counsel will respond with a letter of interpretation. These interpretation letters look at the particular facts presented in the question and explain the agency’s opinion on how the law applies given those facts. These letters of interpretation are guidance documents. They do not have the force and effect of law and are not meant to bind the public in any way. They are intended only to provide information to the public regarding existing requirements under the law or agency policies.
Understanding NHTSA’s Online Interpretation Files
NHTSA makes its letters of interpretation available to the public on this webpage.
An interpretation letter represents the opinion of the Chief Counsel based on the facts of individual cases at the time the letter was written. While these letters may be helpful in determining how the agency might answer a question that another person has if that question is similar to a previously considered question, do not assume that a prior interpretation will necessarily apply to your situation.
- Your facts may be sufficiently different from those presented in prior interpretations, such that the agency's answer to you might be different from the answer in the prior interpretation letter;
- Your situation may be completely new to the agency and not addressed in an existing interpretation letter;
- The agency's safety standards or regulations may have changed since the prior interpretation letter was written so that the agency's prior interpretation no longer applies; or
- Some combination of the above, or other, factors.

ID: nht90-1.8OpenTYPE: Interpretation-NHTSA DATE: January 8, 1990 FROM: Ron Marion -- Sales Engineer, Thomas Built Buses, Inc. TO: Cal Karl -- Commercial Vehicle Section TITLE: None ATTACHMT: Attached to memo dated 11-28-8? from C. Karl to All School Bus LCR II's; Also attached to letter dated 11-27-90 from P.J. Rice to C. Karl (A36; Std. 217); Also attached to letter dated 12-7-82 from F. Berndt to M.B. Mathieson; Also attached to letter dated 1-29-90 from C. Karl to M. Shaw (OCC 4403); Also attached to letter dated 1-18-90 from R. E. Meadows TEXT: This letter is in response to the Department of Public Safety memo recently printed in the January MSBOA newsletter. As a bus body manufacturer we offer "Vandalocks" on both the emergency door(s) and service door of our products. The service door Vandalock is a key activated handle located on the front of the vehicle. When the service door is closed the safety catch holds the door closed. The door cannot be opened from outside the vehicle. The front Vandalock allows the door t o be opened from outside by the use of a cam which releases the safety catch. Please note - the standard entrance door without a Vandalock cannot be opened from outside if the safety catch is engaged. This front Vandalock is not connected to the ignition interlock for several reasons: 1. Federal standards only require the emergency doors (as listed in S5.2.3.1.) to be equipped with the interlock. 2. The door is only locked from the outside; not from the inside. Anyone can get out the door from the inside even if the Vandalock is in the locked position. For this reasoning we feel we comply with Rule 3520.5010 subparagraph 2 for the front door because we are in compliance with FMVSS 217. The Thomas Vandalock for emergency doors utilizes a "slide bolt" lock located on the inside of the door which is connected to an ignition interlock. The bus may not be started with the door "locked". The door may be locked once the bus is started; howe ver, a continuous buzzer will sound if the door is locked while the bus is running, thereby notifying the driver of a problem. This slide bolt type lock is equipped with a spring which requires a positive force to engage. This feature will not allow th e lock to become engaged by vibration or during rollover. Thomas Built Buses has been using this type of Vandalock for at least 15 years (if not longer) without any problems. We feel we are in compliance with the FMVSS 217 for the following reasons: S5.2.3.2. "The engine starting System of a school bus shall not operate if any emergency exit is locked from either inside or outside the bus." Our Vandalock has the ignition interlock and locks the door from inside the bus. For purposes of this requirement "locked" means that the release mechanism cannot be activated by a person at the door without a special device such as a key or special information such as a combination." It has been our interpretation that the words "such as" indicate an example, a key is not required but a "special device" or a combination is not required, but "special information." As I have interpreted this article in the newsletter, the State of Minnesota will require buses with Vandalocks to only be locked from the outside and/or inside with a key or combination. At this time I am not aware of a Vandalock on emergency doors whi ch meets these requirements. Vandalocks, as you are aware, are not necessary for the safe operation of school buses. They are provided at the customer's request to deter vandalism when the vehicles are parked. There probably are numerous school buses in Minnesota which are equipped with Vandalocks which do not meet the 7/1/89 regulations which are now going to be required to be removed at the customer's expense. We at Thomas Built Buses would like for you to reconsider the 7/1/89 regulation to allow our present Vandalock system to be acceptable. Should you have any questions, please do not hesitate to contact me. |

ID: nht90-1.80OpenTYPE: INTERPRETATION-NHTSA DATE: 03/20/90 FROM: STEPHEN P. WOOD -- ACTING COUNSEL, NHTSA TO: R.M. COOPER -- V.P, ENGINEERING, GILL G CORPORATION TITLE: NONE TEXT: This response to your letter asking this agency to consider a problem your company faces with respect to Standard 217, Bus Window Retention and Release (49 CFR @ 571.217). More specifically, you asked how some of your buses could be certified as complyi ng with the emergency exit labeling requirements set forth in Standard 217 for buses other than school buses. I apologize for the delay in this response. Paragraph S5.5.1 of Standard 217 provides that, in buses other than school buses, each push-out window or other emergency exit shall have the designation "Emergency Exit" followed by concise operating instructions, describing each motion necessary to unl atch and open the exit, located within 6 inches of the release mechanism. The purpose of this requirement is to identify for bus occupants the location and explain the use of specially-installed emergency exits. As I understand your letter, you have no difficulties providing appropriate instructions in the specified location. Paragraph S5.5.1 continues with the following language: When a release mechanism is not located within an occupant space of an adjacent seat, a label . . . that indicates the location of the nearest release mechanism shall be placed within the occupant space. The terms "adjacent seat" and "occupant space" are defined in S4 of Standard 217 as follows: "Adjacent seat" means a designated seating position located so that some portion of its occupant space is not more than 10 inches from an emergency exit, for a distance of at least 15 inches measured horizontally and parallel to the exit. "Occupant space" means the space directly above the seat and footwell, bounded vertically by the ceiling and horizontally by the normally positioned seat back and the nearest obstruction of occupant motion in the direction the seat faces. You stated that many of your buses have seats that face the aisle and that back up against windows designated as emergency exits. These aisle-facing seats are "adjacent seats" with respect to the emergency exits. The release mechanism for the emergency exit is not within the "occupant space" for these aisle-facing seats, since the release mechanisms are behind, not above, these seats. You enclosed a group of photographs to further illustrate this situation. Since the release mechanism for the emergency exit is not within the occupant space of these adjacent aisle-facing seats, paragraph S5.5.1 of Standard 217 requires a label indicating the location of the release mechanism for the emergency exit to be plac ed within the occupant space for these seats. You have noted that the occupant space for these seats does not include any place to which this label could be attached. The nearest obstruction of occupant motion in the direction the aisle-facing seats fa ce is the aisle facing seat on the opposite side of the bus. There are no intervening objects other than narrow vertical stanchions in the center of the aisle. Additionally, you suggested that placing the label on the floor or ceiling of the bus would not serve the purposes of this requirement, since those locations would not be readily visible to the seated occupant in an emergency situation. In response to your letter, we have carefully considered the labeling requirements of S5.5.1 as they apply to aisle-facing seats in front of windows that serve as emergency exits. The final rule adopting this additional labeling requirement explained th at NHTSA was concerned that an occupant of an adjacent seat might hinder egress through an emergency exit if the occupant did not know how to use the emergency exit. See 37 FR 9394, at 9395; May 10, 1972. In instances in which the release mechanism its elf is not within the occupant space of an adjacent seat, a label within the occupant space directing the occupant of the seat to the emergency exit instructions will help reduce the likelihood that the occupants would inadvertently obstruct egress throu gh the emergency exits. NHTSA's goal of minimizing the likelihood of inadvertent obstruction of emergency exits is equally applicable to forward-facing and aisle-facing seats. However, the means of achieving that goal (i.e., placing a label within the occupant space of an adjac ent seat, if the release mechanism is not within that occupant space) may not be equally successful for forward-facing and aisle-facing seats. The agency did not focus upon aisle-facing seats when it adopted this labeling requirement. With respect to f orward-facing seats, it is relatively simple to locate a label within the occupant space that will be readily visible both to seated occupants and to persons standing in the aisle, as required by S5.5.2. However, with respect to aisle-facing seats, ther e may not be any location within the occupant space of such seats where a label could be placed so that the label would be visible to occupants of the seat and to persons standing in the aisle. If the labels were not visible in an emergency, such labels would not further NHTSA's goal of minimizing inadvertent obstruction of emergency exits.
Accordingly, we plan to issue a notice proposing to amend and clarify the requirements of S5.5.1 of Standard 217 as they apply to aisle-facing seats. Please note that, unless and until a final rule amending S5.5.1 of Standard 217 becomes effective, the c urrent requirements of S5.5.1 remain in effect for aisle-facing seats. However, the agency believes that it would be inappropriate at this time to enforce the requirement in S5.5.1 that additional information be labeled within the occupant space of aisl e-facing seats given the uncertainty that such labels will serve the purpose for which the labeling requirements were established, as noted above. Accordingly, until the agency makes a final decision on the proposed rulemaking mentioned above, NHTSA wil l not take any enforcement actions against bus manufacturers that do not place a label indicating the location of the nearest emergency exit release mechanism within the occupant space of adjacent aisle-facing seats. |

ID: nht90-1.81OpenTYPE: INTERPRETATION-NHTSA DATE: 03/22/90 FROM: STEPHEN P. WOOD -- ACTING CHIEF COUNSEL, NHTSA TO: KENT D. SMITH TITLE: NONE ATTACHMT: LETTER DATED 1-26-90 TO OFFICE OF CHIEF COUNCIL, NHTSA, FROM KENT D. SMITH, ATTACHED; [OCC-4387] TEXT: This is in reply to your letter of January 26, 1990, to the agency with respect to a safety lighting device. You have asked for our recommendations regarding this invention. The problem addressed by your invention is "that vehicles need some way of signaling following drivers if the headlamps of their vehicles are blinding you." Your solution is to install a button that activates the backup lamps and extinguishes them in a m atter of a second or less. One alternative would be to operate only a single backup lamp, and another, to activate only the license plate lamp. This would provide a warning to the following driver. The agency is concerned with glare, but its investigation of the phenomenon indicates that there are two types: discomfort glare, and disabling glare. Although it is certainly an annoyance, the glare produced by a headlamp shining into a rear view mirror is discomfort glare. In our judgment, a vehicle driver looking into the mirror will not suffer disabling glare so that he is unable to discern vehicles approaching, or pedestrians in the roadway; most vehicles are equipped with manual "day/night" mirro rs which may be easily operated in the event of discomfort. Equipment manufacturers have already addressed the problem by providing rear-view mirrors that have a photoelectric cell that dips them when a certain level of light intensity is reached. In s ummary, the agency does not believe that there is a nationwide safety problem requiring it to mandate the use of your device on motor vehicles as new vehicle equipment. As an aftermarket item which a dealer could offer a new-car purchaser, its installation would be subject to the general prohibition in Federal Motor Vehicle Safety Standard No. 108 that supplemental lighting devices shall not impair the effectiveness of the lighting equipment that Standard No. 108 requires. The question to be answered, therefore, is whether the device would impair the effectiveness of the backup lamps, or other rear lighting devices. The problem here is the necessity of rear lighting d evices to provide clear and unambiguous signals and
messages to following drivers. Anytime a lighting device does not provide a cue to which a following driver is accustomed, the potential for confusion arises. The driving public is unfamiliar with the sudden, though temporary, activation of the backup l amp, at normal driving speeds, or a modification in intensity of the license plate lamp. Without a substantial nationwide public education campaign, the signal imparted by your device is not likely to be understood by a following driver, and might distr act him from the signals of the other rear lighting devices. In this sense, we believe that your device might impair the effectiveness of the lighting equipment that Standard No. 108 does allow. You have also noted the State prohibitions against use of backup lamps when the car is going in a forward direction. Even if the agency concluded that the device was permissible and would not cause impairment, the States are not precluded from enacting and enforcing their own standards on the use of lighting systems. You may be interested to know that two letters to the Editor of The New York Times have appeared on this issue in the last month which suggest the use of existing lighting equipment to signal following drivers that their upper beams are on. I enclose th ese letters for your consideration. I am sorry that we cannot be more encouraging in our remarks, but we do appreciate your interest in motor vehicle safety. Enclosure When the Driver Behind Is Blinding You To the Editor: Until we see the idea of a liquid crystal rear-view mirror, now in one Japanese luxury car, extended to side-view mirrors, as you propose in "Don't Stop There" (editorial, Jan. 18), there is a less than widely known way to dim the discomfort and dange r of bright headlights behind you. While learning to drive in the Catskill Mountains around Monticello, N.Y., I discovered how to let the driver behind know that his or her brights are ripping out your retinas from the rear. As opposed to the signal for an oncoming driver (turning on your own brights, which is hard for an approaching motorist to miss, but useless for someone who can only see your tail lights), you deal with brights from behind by turning your lights completely off, then back on again. Presumably, this demonstrates to the driver behind you, for a moment, that he or she is supplying enough light for both of you. But there's a Catch-22. Drivers who know this signal are typically more experienced and rarely leave their brights on near other vehicles. The most frequent offenders are invariably ignorant of the signal. As more drivers learn the meaning of the off-and-on signal, fewer of us, we may hope, will be blinded by the light from behind. TOM COBIN Bayside, Queens, Jan. 18, 1990 Explaining Lights to the Driver Behind To the Editor: In "When the Driver Behind Is Blinding You" (letter, Feb. 3), Tom Cobin suggests turning your car headlights off and on several times to signal the driver behind that his or her bright lights are on. But this can be dangerous. One's hands should be on the wheel when driving in traffic and not playing with the light switch. Also, driving for even a fraction of a second into an unlighted road is scary. A safer method is to touch the brake pedal barely a time or two, to flash an alert, it is to be hoped, to the car behind that the lights are creating a problem. The safest action is to slow down slightly and to let the offender pass, if the traffic permits. Then, a flash or two of your high beams in his or her rear view mirror might penetrate the skull of this particular thoughtless or careless driver, who i s but one representative of that large percentage at the wheel who should not be driving at all. C. LINCOLN CHRISTENSEN Hurley, N.Y., Feb. 3, 1990 The writer is a longtime member of the Society of Automotive Engineers. |

ID: nht90-1.82OpenTYPE: INTERPRETATION-NHTSA DATE: 03/22/90 FROM: STEPHEN P. WOOD -- ACTING CHIEF COUNSEL, NHTSA TO: LOWELL W. SUNDSTROM TITLE: NONE ATTACHMT: LETTER DATED 12-9-89 TO OFC. OF CHIEF COUNSEL, NHTSA, FROM LOWELL W. SUNDSTROM ATTACHED; [OCC 4251] TEXT: This is in response to your letter of December 9, 1989 to this office, asking us to confirm your opinion that Standard No. 302, Flammability of Interior Materials (49 CFR @ 571.302) does not apply to the "HOOD LOCKER" product you describe in your letter. You state that this product will be a plastic box to hold tissues which consumers may use to wipe off the engine crankcase dipstick when checking the crankcase oil. According to your letter, the product can be mounted near or on the vehicle fender wel l, on the under side of the hood, on the side or top of the air cleaner, or in another location near the dipstick. You believe that Standard No. 302 does not refer to the product because it will not be placed within the occupant compartment of motor vehi cles and will not be placed within one-half inch of any occupant's air space. I am pleased to have this opportunity to explain our law and regulations for you. By way of background information, the National Highway Traffic Safety Administration (NHTSA) has no authority to certify or approve motor vehicles or motor vehicle equipment for compliance with the Federal Motor Vehicle Safety Standards. Instead, the Na tional Traffic and Motor Vehicle Safety Act (the Safety Act; 15 U.S.C. 1381 et seq.) establishes a "self-certification" process under which each manufacturer is responsible for certifying that every one of its products complies with all applicable safety standards. This agency periodically tests vehicles and items of motor vehicle equipment for compliance with the safety standards, and also investigates other alleged defects related to motor vehicle safety. The Safety Act also gives this agency authority to issue safety standards applicable to new motor vehicles and new items of motor vehicle equipment. We have exercised this authority to establish Standard No. 302. That standard sets forth flammability r esistance requirements applicable to all new motor vehicles. Therefore, any motor vehicle manufacturer that installs your "HOOD LOCKER" as original equipment in its vehicles must certify that the vehicle meets all applicable safety
standards, including Standard No. 302, with the "HOOD LOCKER" installed. However, Standard No. 302 does not apply to aftermarket items of motor vehicle equipmen, as your "HOOD LOCKER" appears to be. Hence, you are not required to certify that this produ ct complies with Standard No. 302 before offering it for sale. Parenthetically, I note that your observation is correct that Standard No. 302 applies only to materials used in the occupant compartment of motor vehicles, and not to materials used in an e ngine compartment that is separated from the occupant compartment. However, there are other statutory requirements that may affect this product. First, manufacturers of motor vehicle equipment such as this "HOOD LOCKER" are subject to the requirements in sections 151-159 of the Safety Act (15 U.S.C. 1411-1419) concernin g the recall and remedy of products with defects related to motor vehicle safety. If either the equipment manufacturer or this agency were to determine that the "HOOD LOCKER" contained such a defect, the manufacturer would have to notify purchasers of t he defect and remedy the problem free of charge to the purchasers. Second, use of this product could be affected by section 108(a)(2)(A) of the Safety Act (15 U.S.C. 1397(a)(2)(A)). That section prohibits manufacturers, distributors, dealers, or repair shops from knowingly "rendering inoperative" devices or elements of design that were installed in a motor vehicle to comply with the Federal motor vehicle safety standards. To avoid a "rendering inoperative" violation, the above-named parties should examine the proposed installation instructions for the "HOOD LOCKER" a nd compare those instructions with the requirements of our safety standards, to determine if installing the "HOOD LOCKER" in accordance with those instructions would result in the vehicle no longer complying with the requirements of the safety standards. The most relevant safety standards would seem to be Standards No. 113, Hood Latch System, and 302. If the installation of the "HOOD LOCKER" would not result in a rendering inoperative of the vehicle's compliance with the safety standards, the "HOOD LO CKER" can be installed by dealers, distributors, and repair shops without violating any Federal requirements. I trust that we have been responsive to your questions. For your information, I am enclosing an information sheet for new manufacturers of motor vehicles and motor vehicle equipment and information on how to obtain copies of motor vehicle safety standar ds. Please feel free to contact us if you have any further questions. ENC. |

ID: nht90-1.83OpenTYPE: INTERPRETATION-NHTSA DATE: 03/23/90 FROM: STEPHEN P. WOOD -- ACTING CHIEF COUNSEL, NHTSA TO: TILMAN SPINGLER -- ROBERT BOSCH GMBH TITLE: NONE ATTACHMT: LETTER DATED 2-13-90 TO TAYLOR FROM RICH VAN IDERSTINE, NHTSA, ATTACHED [43880]; ALSO ATTACHED TELEFAX TO RICHARD VAN IDERSTINE, NHTSA, FROM T. SPINGLER, ROBERT BOSCH GMBH, DATED 1-30-90. TEXT: This is in reply to your FAX to Richard Van Iderstine of this agency, asking for an interpretation of Federal Motor Vehicle Safety Standard No. 108. Your first question is: 1) To turn the adjusting screws of a HB-2 headlamp it will be necessary to remove two snap on covers without the use of any tool. Will this be legal? Section S7.7.2 requires a headlamp to be installed with a mounting and aiming mechanism that allows aim inspection and adjustment, "and is accessible for those uses without removal of any vehicle parts, except for protective covers removable without the use of tools." The section is not directed to the number of covers, only the ease of removal for the specified purposes. Therefore, the use of two snap on covers is not prohibited by Standard No. 108. Your second question is: 2) A combination of HB2-headlight (low + high beam) and auxiliary driving beam in one unit shall be equipped with only vertical adjusting screws for the driving beam. The beam pattern will be so wide that even bulbs with extreme tolerances will allow to meet all photometric requirements without horizontal adjustment. Will this be legal? Under section S7.7.2, the aiming mechanism of a headlamp must allow for adjustment of both horizontal and vertical aim. Thus, the portion of the lamp that provides the lower and upper beam must have both horizontal and vertical aiming screws, and the he adlamp would not comply with S7.7.2 if either aiming screw is lacking. For that part of the same headlamp that is a driving beam and which is therefore not regulated by Standard No. 108, the manufacturer may provide any means of adjustment it wishes, as long as it does not impair the effectiveness of the aim of the upper and lower headlamp beam. Your final question is: 3) When will the 9007 bulb be legal? Date of final rule? According to the plans of this agency, further action on the 9007 (proposed to be known as HB5) is expected in May 1990. I hope that this responds to your questions. |

As I told you in our telephone conversation yesterday, you have correctly noted the error in the Federal Highway Administration's position concerning emerge ncy exits on school buses. The letter to Ms. Finkel does not take into account the amendments which occurred in Standard 217 (49 C.F.R. S 571.217) to specifically address the emergency exit requirements of school buses. As you correctly noted in your letter, the predecessor of th e current Standard 217 did not distinguish between school and non-school buses. The application of the old standard to both categories of buses was problematic. The revision of the standard established two separate categories of buses governed by different emergency exit requirements. Your responsibility as a manufacturer of school buses is to comply with the specific standard for school buses provided in S 5.2 .3.1. Mr. Trentacoste's letter fails to take into account the revisions in Standard 217, which were adopted to address this very problem. If you have any questions, feel free to contact me at your convenience. |

Seminole Solar Systems, In c. of Largo; Allied Glass Tint, Inc. of Tampa, 3801, Inc., d/b/a Window Kote, and Solar Graphics, Inc., of St. Petersburg, were named as defendants in the Tampa Division or the Middle District of Florida. Under National Highway Traffic and Safety Administration Acts standards, automobile glass must transmit at least 70 percent light through their surfaces. The civil complaints allege that the named defendants applied coated materials to the windows of motor vehicles in an amount resulting in transmission of light less than that permitted by the standard. Mr. Genzman stated that the applicable federal standards were imposed to establish minimum visibility standards and to prevent accidents. The civil complaints seek to enjoin violation of the Act, and to impose $ 800,000.00 in civil penalties. |

ID: nht90-1.88OpenTYPE: INTERPRETATION-NHTSA DATE: MARCH 29, 1990 FROM: STEPHEN P. WOOD -- ACTING CHIEF COUNSEL, NHTSA TO: J. BRETTSCHNEIDER -- ROBERT BOSCH GMBH TITLE: NONE ATTACHMT: LETTER DATED 8-31-89 TO RICHARD VAN IDERSTINE, NHTSA, FROM J. BRETTSCHNEIDER, ROBERT BOSCH GMBH, ATTACHED. TEXT: This is in reply to your letter to Mr. Van Iderstine of this agency, with reference to the performance of the impact test according to SAE J1383. I regret the delay in responding. You state that according to paragraph 4.10.3 of J1383, the impact test is conducted along the mechanical axis, and that paragraph 2.14 of SAE J579 defines the mechanical axis as perpendicular to the aiming plane through the geometric center of the lens. With respect to this, you have asked two questions: "where is the geometric center of a lens without aiming pads?", and "where is the geometric center of a lens which moreover covers two compartments, one for the lower beam and one for the upper beam?" First, we must advise you that the impact test of J1383 is not required for any headlamp covered by Federal Motor Vehicle Safety Standard No. 108. The impact test that is required for integral beam and replaceable bulb headlamps is specified in section S8.8, and we shall answer your questions with respect to its provisions. S8.8 states in part that "one impact shall be delivered to the center of the lens on the mechanical axis." This language originated in 1983 with the adoption of specifications for replaceable bulb headlamps, when a headlamp was not permitted to incorporate more than one light source. Thus, the lens center and mechanical axis were coincident. Now that Standard No. 108 permits two standardized replaceable light sources in a headlamp, there are two mechanical axes. We also note that lamps may now use Vehicle Headlamp Aiming Devices, and thus have lenses without aiming pads. As we understand your concern, you appear to be uncertain as to the location of the impact for the test of section S8.8. After reviewing your letter, we have concluded that the language "on the mechanical axis" is a redundancy. Thus, the impact should be applied on the center of the lens, without reference to the mechanical axis. We consider the center of the lens to be the intersection of the lens and a line which is parallel to the longitudinal axis of the vehicle and passes through the centroid of the projected lens area as viewed on a plane perpendicular to the longitudinal axis of the vehicle. We shall be pleased to answer any further questions you may have. |
