What type of regulations does the Bureau of Alcohol, Tobacco, Firearms, and Explosives enforce?

The Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) primarily enforces regulations related to the manufacture, distribution, and possession of firearms and explosives, as well as regulations concerning alcohol and tobacco. This agency is responsible for ensuring compliance with laws that promote public safety, prevent crime, and regulate the lawful use of these items. The ATF creates and enforces rules that govern the sale and ownership of firearms, as well as the regulation of explosives to minimize risks associated with their use.

In contrast, the other options do not pertain to the ATF's core mission. International treaties fall under the jurisdiction of the State Department, and transportation safety is generally governed by the Department of Transportation and the Federal Aviation Administration. Trade regulations are typically the responsibility of the Department of Commerce and the U.S. Customs and Border Protection. Therefore, focusing on the ATF's specific mandate highlights why regulations on firearms and explosive safety are the central concern of this agency.
