How close to the travel part of the roadway can you park with division 1.2 or 1.3 materials?

When parking vehicles transporting Division 1.2 or 1.3 materials (explosives) near a roadway, regulations typically mandate a distance of at least 300 feet from the travel part of the roadway. This distance may vary based on local regulations and specific circumstances, so it's essential to check with local authorities or regulations for precise guidelines. Additionally, proper signage and safety measures should be observed when parking such vehicles.
