A vehicle or mechanical equipment is excepted from the requirements of this subchapter if any of the following are met: 1 <<>> (3) The vehicle or mechanical equipment is stowed in a hold or compartment designated by the administration ol the country in which the vessel is registered as specially designed and approved for vehicles and mechanical equipment and there are no signs of leakage from the battery, engine, fuel cell, compressed gas cylinder or gasoline transported by U.S. vessels, see 46 CFR 70.10-1 and 90.10-38; accumulator, or fuel tank, as appropriate. For vehicles with batteries connected and fuel tanks containing My understanding is that subchapter "C" in the HMR comprise the complete "HAZARDOUS MATERIALS REGULATIONS" which would include parts 171-180. In the stowage of vehicles on vessels, If a vessel comply with 476.905(i)(3) including the references in 46 CFR that are noted, the offerer/shipper does do not have to comply with 49CFR176.905(a)(2).
