SUPPLEMENTARY INFORMATION: On December 29, 2021, NHTSA issued a final 
rule titled ``Federal Motor Vehicle Safety Standards; Bus Rollover 
Structural Integrity.'' 86 FR 74270. The final rule established FMVSS 
No. 227, a new Federal Motor Vehicle Safety Standard that subjects 
over-the-road buses (motorcoaches) and other large buses to a rollover 
test, and requires applicable buses provide a ``survival space'' to 
protect occupants from possible collapse of the bus structure around 
them. The final rule also prohibits emergency exits from opening during 
the rollover test. This rule became effective December 30, 2024.
    On November 13, 2023, NHTSA issued a final rule titled ``Federal 
Motor Vehicle Safety Standards; Bus Rollover Structural Integrity,'' 
which partially granted petitions for reconsideration to the December 
2021 final rule. 88 FR 77523. This final rule amended the definition of 
``transit bus'' and revised the maximum allowable weight of objects 
intruding into the survival space during the rollover test described in 
the paragraph above. This rule became effective on December 30, 2024.
    On January 20, 2025, the President issued a memorandum titled, 
``Regulatory Freeze Pending Review,'' 90 FR 8249 (Jan. 28, 2025), to 
direct executive departments and agencies to consider postponing for 60 
days the effective date for any rules that had been published in the 
Federal Register but had not taken effect for the purpose of reviewing 
any questions of fact, law, and policy that the rules may raise. While 
not explicitly subject to the President's memorandum, NHTSA is 
providing notice that it will exercise its enforcement discretion and 
not enforce the provisions of the Bus Rollover Structural Integrity 
final rule and Bus Rollover Structural Integrity final rule; petitions 
for reconsideration until March 20, 2025, to allow the officials 
appointed or designated by the President to review the final rule to 
ensure that it is consistent with the law and Administration policies.

    Issued in Washington, DC, under authority delegated in 49 CFR 
1.95 and 501.5.
Peter Simshauser,
Chief Counsel.
