TITLE: FMVSR INTERPRETATION

TEXT: This is in reply to your letter of March 14, 1973, asking how to comply with NHTSA Certification regulations in cases where you supply a trailer chassis or frame only, and another manufacturer installs the body. In another example, you supply the vehicle without an axle assembly, which is, we assume, also installed by another party.

Based on your letter, the procedures to be followed in certifying vehicles such as these are those contained in NHTSA regulations for "Vehicles Manufactured in Two or More Stages" (49 CFR Part 568, copy enclosed). Briefly, these regulations require the incomplete vehicle manufacturer, who would be you in these cases, to furnish with the incomplete vehicle a document indicating the extent that the incomplete vehicle conforms to Federal standards, and what the final stage manufacturer must do in order that the completed vehicle will conform to all applicable standards.

If upon your review of these regulations you have further questions, we will be pleased to respond to them.

ENC.
