A diplomatic flag is a special flag that is used on the cars of diplomats from one country when they visit another country. Diplomats are sent by their government to represent the country in foreign countries. The diplomatic flag helps other countries recognize them as representatives from the government of a particular country. The flag looks like the country's national flag, but it is slightly different. For example, if the United States diplomatic flag is flying from the car of a US diplomat, the US flag will have a golden eagle on a white background instead of the stars and stripes. This way, other countries know that this car is driven by an official from the US government.
