DOT posts 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—Federal Docket Management System), which can be reviewed at                     *www.transportation.gov/​privacy.*

## II. Legal Basis

                    FMCSA has authority under 49 U.S.C. 31315(b) to grant exemptions from certain parts of the Federal Motor Carrier Safety Regulations (FMCSRs). FMCSA must publish a notice of each exemption request in the                     **Federal Register**                     (49 CFR 381.315(a)). The Agency must provide the public an opportunity to inspect the information relevant to the application, including any safety analyses that have been conducted. The Agency must also provide an opportunity for public comment on the request. The Agency reviews the safety analyses and the public comments and determines whether granting the exemption would likely achieve a level of safety equivalent to or greater than the level that would be achieved by the current regulation (49 CFR 381.305). The decision of the Agency must be published in the                     **Federal Register**                     (49 CFR 381.315(b)). If the Agency denies the request, it must state the reason for doing so. If the decision is to grant the exemption, the notice must specify the person or class of persons receiving the exemption and the regulatory provision or provisions from which an exemption is granted. The notice must specify the effective period of the exemption (up to 5 years) and explain the terms and conditions of the exemption. The exemption may be renewed (49 CFR 381.315(c) and 49 CFR 381.300(b)).

The vehicle must have as many additional fusees or liquid-burning flares as are necessary to satisfy the requirements of § 392.22, (3) Other warning devices may be used in addition to, but not in lieu of, the required warning devices, provided those warning devices do not decrease the effectiveness of the required warning devices.
