Internal border control

Internal border control refers to measures implemented within a country's own borders to regulate movement across different regions or areas, enhancing security and safety. Unlike external borders, which involve customs and immigration checks at entry points, internal border controls may include checkpoints, ID verification, or monitoring to prevent crime, illegal activities, or unauthorized movement. They are often used in specific situations such as emergencies, national security concerns, or in regions with high risk of threats. While they can limit free movement within a country, their goal is to protect citizens and maintain national security.
