Legal Definitions - border search

A border search is a type of search conducted at the border of a country, usually at a checkpoint, for the purpose of excluding illegal aliens and contraband. It can also refer to a search conducted near the border of a country. Generally, searches near the border are treated no differently from those conducted elsewhere in the country.

For example, if a person is crossing the border from Mexico into the United States, a border search may be conducted to ensure that the person is not carrying any illegal drugs or weapons. The search may involve a thorough examination of the person's belongings and body.

Border searches are permitted under the general authority of the United States to ensure the integrity of its borders. However, the right to remain silent and protect one's personal belongings from government intrusion, normally afforded constitutional protection, are surrendered at the border.
