Checkpoints are designated locations where vehicles or individuals are stopped for inspection. They are commonly used by law enforcement or security personnel to check for compliance with laws, regulations, or safety standards. Checkpoints can be set up for various purposes, such as traffic safety, border control, or public health measures. At a checkpoint, officers may ask for identification, inspect vehicles, or conduct searches. The goal is to ensure safety and security within a specific area. Checkpoints can be temporary or permanent, depending on the situation and the objectives of the authorities involved.
