The DOT acronym is mostly used in the United States and the United Kingdom to abbreviate Department of Transportation. Other meanings of DOT include damage over time, directly observed therapy and the Department of the Treasury.
Each U.S. state has a Department of Transportation responsible for overseeing highways, waterways, railroads and other related facilities. The United Kingdom's Department for Transport's former name was the Department of Transport; as a result, the DoT abbreviation is still used informally as of 2015. In the context of video and computer games, damage over time is the measure of damage on a character that is distributed over a period of time, such as an attack by poison. In the medical field, directly observed therapy describes the strategy of a health care worker watching a patient take prescribed medicine as opposed to trusting the patient to take his medication.
