with 5 U.S.C. 553(c), DOT previously solicited comments from the public to better inform its rulemaking process. DOT posted these comments, without edit, including any personal information the commenter provides, to www.regulations.gov, as described in 
the system of records notice (DOT/ALL– 14 FDMS), which can be reviewed at www.dot.gov/privacy. 
Corrections 
FMCSA is making minor corrections 
to fix errors found in the final rule 
published on July 22, 2016. In § 393.11, the Agency corrects Footnote 11 of Table 1 to read ‘‘No rear license plate lamp is required on vehicles that do not display a rear license plate.’’ FMCSA inadvertently omitted the word ‘‘not’’ in this footnote. The Agency corrects section 1.l.(4)(b) 
of Appendix G to Subchapter B of Chapter III, to read ‘‘only to the vehicle’s stop lamp circuit.’’ FMCSA inadvertently omitted the phrase ‘‘vehicle’s stop lamp circuit’’ in this section. 
As noted in the final rule, the 
National Highway Traffic Safety Administration had extended the compliance date for antilock brake systems (ABS) on hydraulic braked vehicles from March 1, 1999, to September 1, 1999, but that action was limited to an extension of the malfunction indicator lamp requirement in S5.3.3(b) of FMVSS No. 105—and not for the general requirement to equip hydraulic-braked vehicles with ABS. As such, all hydraulic-braked vehicles were still expected to be equipped with ABS effective March 1, 1999. While FMCSA included footnotes to help explain the different effective dates for the various ABS requirements in the Appendix G periodic inspection requirements, those footnotes are amended and repositioned to accurately reflect the effective dates for the various ABS requirements in Appendix G. 
Lastly, section 1.l.(5) is amended to 
note that it only applies to towed vehicles equipped with air brakes.
