TITLE: FMVSS INTERPRETATION
TEXT: We have received copies of your letter of March 28, 1973, to the ten Regional Administrators of this agency, concerning the compliance of your vehicles with Standard No. 108. You state that law enforcement officials in certain jurisdictions are citing your semitrailers for lack of clearance lamps when, as a matter of fact, the vehicles are equipped with combination turn signal and clearance lamps located near the lower rear corners of the vehicle. You ask the Regional Administrators to advise the local authorities that this lamp configuration conforms to Standard No. 108 and "that any conflicting state regulation is unenforceable under the provisions of Section 103(d) of the Traffic Safety Act."
Paragraph S4.3.1.4 of Standard No. 108 states, "Where the rear identification lamps are mounted at the extreme height of a vehicle, rear clearance lamps need not meet the requirement of Table II that they be located as close as practicable to the top of the vehicle." Since the identification lamps depicted in your drawing are at the extreme height of the vehicle, the location you have chosen for the clearance lamps in allowed by Standard No. 108. Section 103(d) of the National Traffic and Motor Vehicle Safety Act, 15 U.S.C. 1392(d), renders void any State law with differing requirements for this equipment.
I am sending a copy of this letter to the Regional Administrators.
Sincerely,
March 28, 1973
This letter was sent to Regional Administrator, Dept. of Transportation, National Highway Traffic Safety Administration, at each of the 10 Regional Offices on attached page.
Dear Sir:
In the past few months we have (upon customer specification) been building highway semi-trailers with only the three identification lamps on the top-rear of the vehicle. The two rear clearance lamps have been combined with the turn-signal lamps and are not at the customary top corner locations (SEE ATTACHED SKETCH).
In our opinion this is a perfectly legal situation under sections S4.3.1.5 and S4.4.1 of Federal Motor Vehicle Safety Standard #108, established pursuant to Public Law 89-563.
In some states, these vehicles are being cited for "not having rear clearance lamps", due in part I feel to a lack of knowledge or understanding on the part of the state enforcement people that these trailers in fact do have the legally required lamps.
Would you please inform the proper enforcement people in the states within your region of the legality of this particular lamp configuration under Federal law and that any conflicting state regulation is unenforceable under the provisions of Section 103(d) of the National Traffic and Motor Vehicle Safety Act of 1966 (Public Law 89-563).
Please advise the undersigned of the situation with respect to this matter in your particular region so that we may in turn inform our customers accordingly.
Sincerely,
R. J. Deller -- Vice President of Engineering, TRAILMOBILE
