Dear Mr. Schang: This responds to your telephone request of June 17, 1976, fo confirmation that S 575.101 of Part 575, *Consumer Information*, was recently revised to specify vehicle stopping distance information based on stops that may include wheel lockup under the conditions allowed by Standard No. 105-75, *Hydraulic Brake Systems*. You note that the text of S 575.101(c)(5), and the accompanying illustration in Figure 1 of the section, describe the information provided as performance achieved 'without locking the wheels.'; Your interpretation of the requirements of S 575.101 is correct. I amending Part 575 to permit the use of stopping distance data collected in tests for Standard No. 105-75, the agency made all changes it believed necessary to provide for the use of stopping distance information gathered in connection with Standard No. 105-75 (41 FR 1066, January 6, 1976). The reference to 'without locking the wheels' should have been deleted from the text of S 575.101(c)(5) and Figure 1. A correcting amendment will be issued shortly.; The correction of an omission from the text of the first paragraph of 575.101(c) will also be made at that time. In the last sentence of that paragraph, the concluding option (as published in the *Federal Register*) should read 'under the procedures specified in paragraph (d) of this section and the conditions specified in paragraph (e) of this section.'; Sincerely, James B. Gregory, Administrator
