In an unusual development, two private companies have separately applied to the Federal Motor Carrier Safety Administration (FMCSA) for long-term exemptions from the Hours of Service (HOS) regulations. Both applications, published in the Federal Register on June 30, request operational flexibility for drivers responding to emergency situations rather than routine freight movements. While HOS waivers are not uncommon, simultaneous requests from two unrelated private companies have drawn attention across the trucking industry because exemptions, if approved, can remain in effect for up to five years.

The first applicant, Lone Star Haz Mat Response, is seeking permission for its field-response drivers to exceed HOS limits when returning to their home base after hazardous materials emergency operations. The second, Mainline Services LLC, has requested similar relief for drivers transporting specialized equipment used to respond to train derailments, disabled railcars, and debris blocking railroad rights-of-way. Both companies argue that emergency response work is inherently unpredictable and can extend well beyond normal duty hours, making strict compliance with existing HOS limits operationally challenging. Public comments on both applications remain open through July 30.

The requests have also sparked debate within the transportation community. Safety consultant Michael Millard submitted comments opposing both applications, arguing that granting company-specific exemptions could create an uneven competitive environment while raising safety concerns. Supporters, however, contend that faster deployment of emergency response resources is essential when hazardous materials incidents or rail disruptions threaten public safety and interstate commerce. The FMCSA will review stakeholder feedback before determining whether either exemption should be granted, making this a closely watched regulatory development for carriers, emergency response providers, and the broader logistics industry.
