This research focuses on issues faced by state agencies when trying to successfully implement regulatory relief of overweight commercial motor vehicle requirements during emergencies. The objectives of this research are to (a) develop consistent definitions of emergencies, emergency commodities (classification/type), and other concepts; (b) identify successful practices, procedures, and processes for increasing weight limits during emergencies, including coordination and harmonization with neighboring jurisdictions; (c) develop a decision framework that considers different emergency scenarios that are linked with successful practices, procedures, and processes; and (d) highlight successful communication practices and training opportunities to conduct before emergencies occur. This report describes the research performed so far in this project, along with relevant findings for the following tasks:
The review of the literature (Task 2) revealed the following:
of OS/OW vehicles since the Federal Highway Administration (FHWA) has no authority to do so.
The stakeholder interviews and review of current best practices in Task 3 revealed the following (detailed conclusions are in Chapter 3):
however, distinct definitions of divisible and non-divisible loads may not be as clear to nontraditional carriers applying for special permits.
These tasks relied on the findings of the previous tasks and feedback from representatives of the end users of the final deliverables. The discussions provided valuable insights into the challenges and considerations associated with managing emergency declarations and ensuring smooth coordination across states and jurisdictions. A need for streamlined communication and guidelines to ensure effective responses to emergencies emerged along with following needs:
The final deliverables were developed based on the findings of all these above-mentioned tasks, and best practices were woven into the guide along with the tools and resources that the intended audience can use.
