Mr. F. E. Stephens Vice President, Marketing 1925 Indiana Avenue Salt Lake City, UT 84125

Dear Mr. Stephens

This is in response to your letter forwarding your firm's vehicle identification numbering system and requesting confirmation that it complies with Federal Motor Vehicle Safety Standard No. 115 -Vehicle identification number.

The National Highway Traffic Safety Administration (NHTSA) does not give advance approval of a manufacturer's compliance with motor vehicle safety standards or regulations, as it is the manufacturer's responsibility under the National Traffic and Motor Vehicle Safety Act to ensure that its vehicles comply with the applicable safety standards. However, my office has reviewed your proposed system. Based on our understanding of the information which you have provided, your system apparently complies with Standard No. 115.

Sincerely,

Frank Berndt Chief Counsel
