Dear Mr. Blair:

This is in response to your letter dated February 2, 1998, requesting clarification on the transportation of explosives on vehicles in combination. Specifically you ask whether Division 1.1 or 1.2 explosives may be carried on any vehicle or combination of vehicles with any Division 2.3 (poison gas 'or 6.1 (poisonous) materials under the Hazardous Materials Regulations (HMR.; 49 CFR parts 171-180).

The answer is no. Section 177.835(c) states that Division 1.1 or 1.2 materials may not be loaded into or carried on any vehicle or a combination of vehicles if the other vehicle in 'the combination contains "Division 2.3 (poisonous gas) or Division 6.1 (poisonous) materials." The phrase "Division 2.3 (poisonous gas) or Division 6.1 (poisonous) materials" includes all Division 2.3 materials, regardless of hazard zone, and all Division 6.1 material, regardless of the physical state or packing group of the material.

I hope this satisfies your request.
