The correct answer indicates that states and counties may require permits to transport certain explosives or hazardous wastes because these entities have the authority to establish regulations that specifically address the transportation of dangerous goods within their jurisdictions.

State and county regulations can be influenced by local conditions and concerns, such as population density, environmental factors, and infrastructure capabilities. As a result, they can impose specific requirements that complement federal regulations, including the issuance of permits to ensure safe transportation practices. This ensures that operations align with regional safety protocols and governmental policies regarding hazardous materials.

While federal agencies set broad national standards and may regulate hazardous materials at a national level, the requirement for permits can also significantly vary depending on state and county legislation, making them primarily responsible for permitting at more localized levels.
