NASEO completed an update to its “Guidance for States on Relief from Federal Motor Carrier Safety Regulations in an Energy Emergency” which provides clarification on changes in CFR §390.23 and includes market factors and conditions that can assist states in making decisions on whether waivers are needed. It also explains how the waivers apply to intra- and inter-state trucks and those with hazardous material designation (which fuel haulers fall under) and clarifies that tanker trucks returning home empty cannot transport petroleum products that are not related to relief of the emergency event on the return trip home under the safety waivers. Finally, it encourages communication among the states and the Federal Motor Carrier Safety Administration on the use of state and federal regional waivers for emergency relief.
