Dear Mr. McIntyre:
This responds to your letter to the Federal Highway Administration asking for an interpretation of Federal Motor Vehicle Safety Standard No. 104, Windshield washing and wiping systems. Since the National Highway Traffic Safety Administration (NHTSA) is responsible for administering the Federal motor vehicle safety standards (FMVSS) , including Standard No. 104, your letter was referred to my office for reply. I regret the delay in this response.
Your letter concerns a standard issued by the Society of Automotive Engineers (SAE) and referenced in S4.2.2 of Standard No. 104. S4.2.2 specifies that each multipurpose passenger vehicle, truck and bus shall have a windshield washing system that meets the requirements of SAE Recommended Practice J942, November 1965 (as modified). You explain that you chair an SAE subcommittee that developed a new Recommended Practice J1944, "Truck & Bus Multipurpose Vehicle Windshield Washer System," that you believe is more suitable for testing "commercial vehicles." You ask whether NHTSA would "allow for documentation of compliance to FMVSS 104 through use of the new J1944 recommended practice or is it necessary to evaluate per J942 as specifically written."
Your question raises two issues, both of which concern how a test procedure specified in the Federal motor vehicle safety standards may vary in practice from that described in the standard. The first issue is whether a vehicle manufacturer is obligated to test its vehicle only in the manner specified in Standard No. 104, i.e., only by using J942 and not the newly developed J1944. The answer is no. Each of NHTSA's safety standards specifies the test conditions and procedures that this agency will use to evaluate the performance of the vehicle or equipment being tested for compliance with the particular safety standard. However, NHTSA does not require a manufacturer to test its products only in the manner specified in the safety standards. A manufacturer may choose any means of evaluating its products to determine whether the vehicle or item of equipment complies with the requirements of Standard No. 104, provided, however, that the manufacturer assures that the vehicle will comply with the standard when tested by NHTSA.
If NHTSA's compliance test of Standard No. 104 were to show an apparent noncompliance of a vehicle with the standard, the vehicle manufacturer would be asked to show the basis for its certification that its vehicle complies with the standard. If in fact there is a noncompliance, the manufacturer would be subject to civil penalties unless it can establish that it exercised "reasonable care" in the manufacture of the product and in the checks (through actual testing, computer simulation, engineering analyses, or other means) to ensure compliance.
We cannot tell you at this time whether a manufacturer's use of J1944 to certify a vehicle's compliance with Standard No. 104 would constitute "reasonable care." NHTSA is unable to judge what efforts constitute "reasonable care" outside of the course of a specific enforcement proceeding. What constitutes "reasonable care" in a particular case depends on many factors, including such things as the limitations of current technology, the availability of test equipment, the size of the manufacturer, and above all, the diligence exercised by the manufacturer.
The second issue raised by your question is whether NHTSA is required to use J942 in the agency's compliance tests. The answer is yes, as long as J942 is incorporated into the test procedure of Standard No. 104. When conducting its compliance testing, NHTSA must precisely follow each of the specified test procedures and conditions set forth in the safety standard. If a different procedure or condition is desirable, the agency must undertake rulemaking to amend the standard to incorporate the desired change.
You ask in your letter about the procedure for amending Standard No. 104. NHTSA has a process whereby you can petition for a change to the FMVSS, including Standard No. 104. The petitioning procedure is outlined at 49 CFR part 552 Petitions for rulemaking, defect, and noncompliance orders (copy enclosed). Very briefly, section 552.4 states that a petition should be addressed and submitted to: Administrator, NHTSA, 400 Seventh Street, SW, Washington, DC 20590. Each petition must be written in English, have a heading that includes the word "Petition," set forth facts which it is claimed establish that a change to the regulation is necessary, set forth a brief description of the substance of the revised regulation which it is claimed should be issued, and contain the name and address of the petitioner. After receiving the petition, NHTSA conducts a technical review to determine whether there is a reasonable possibility that the requested regulatory change will be issued at the end of the appropriate rulemaking proceeding.
You state that J1944, the newer SAE standard, is overall a "tougher" document than J942. You should be aware that NHTSA cannot automatically incorporate a "tougher" version of an incorporated document into the FMVSS. Before NHTSA incorporates an upgraded standard, NHTSA examines whether there is a safety need for the newer requirements. In its examination, NHTSA considers data from all sources, including the petitioner. If you decide to submit a petition, you ought to explain the safety need for the new requirements and provide an analysis of the increased costs likely to be associated with the new requirements.
I hope this information is helpful. If you have any further questions. please contact Dorothy Nakama of my staff at this address or by telephone at (202) 366-2992.
Sincerely,
Philip R. Recht Chief Counsel
Enclosure ref:104 d:2/3/95 While the exercise of "reasonable care" may relieve a manufacturer of liability for civil penalties for the manufacture and sale of noncomplying vehicles or equipment, it does not relieve a manufacturer of the responsibility to notify purchasers of the noncompliance and remedy the noncompliance free of charge.
