Yes. As a matter of public safety, governments at all levels have passed legislation restricting the transportation of dangerous goods. Some commodities may be included in your shipment under controlled conditions while law prohibits transport of others. In either case, you must disclose to the van operator every item you intend to include with your shipment that poses a hazard. A few prohibited items include: gasoline, propane tanks, oxygen, fire extinguishers, ammunition and fireworks.
