Additional state-level review applies for:

3. Oregon Hazmat Route Restrictions

Oregon designates specific routes for hazardous materials—some areas prohibit or restrict hazmat loads.

Common restrictions include:

  • Hazmat tunnels closed or restricted to certain classes

  • City/municipal restrictions, especially in Portland and Eugene

  • Bridge restrictions for explosives or flammable materials

  • Mountain pass closures during severe weather

Drivers must follow:

4. Travel Time Restrictions

Many hazmat loads cannot operate during:
