FMCSA grants a limited 90-day waiver from the 30-minute rest break provision of the Federal hours-of-service (HOS) regulations for the transportation of livestock, as defined in 7 U.S.C. 1471(2). Several associations representing various segments of the livestock industry raised concerns about the risks to the health of animals from rising temperatures inside livestock trucks during drivers’ mandatory 30-minute break, especially on light of long-range weather forecasts for above-normal temperatures for July, August and September 2013. The industry requested relief, and the Agency has determined that it is appropriate to grant a limited 90-day waiver for this period to ensure the well-being of the Nation’s livestock during interstate transportation. The Agency has determined that the waiver, based on the terms and conditions imposed, would likely achieve a level of safety that is equivalent to, or greater than, the level that would be achieved absent such waiver. This waiver preempts inconsistent State and local requirements.
