What does 49 CFR 397.103 (Requirements for State routing designations) require?

Short answer

49 CFR 397.103 requires states to designate routes for hazardous materials transportation.

The rule applies to states and their routing designations for hazardous materials.

The rule says

"A State shall develop, publish, and enforce route designations as required by this section." (49 CFR 397.103)

"The routing requirements of this section apply to the transportation of hazardous materials by motor vehicle in intrastate commerce." (49 CFR 397.103)

In plain English

This means states must create and enforce specific routes for trucks carrying hazardous materials, which can impact how carriers plan their routes and ensure compliance with federal regulations. States have some flexibility in designating these routes, but they must follow federal guidelines.

What to do

• Review the federal guidelines for route designations in 49 CFR 397.103
• Check with state authorities to determine specific route designations for hazardous materials transportation
• Ensure carrier routes comply with both federal and state regulations
