What is a barricade?

A barricade is defined as a temporary obstruction that is set up to control or restrict traffic flow, protect construction sites, or limit access to hazardous areas. It is often used in situations where safety is a concern, such as during road work or to cordon off dangerous areas. The key characteristic of a barricade is its temporary nature; it can typically be moved or dismantled quickly as the situation changes or as work is completed.

In contrast, a permanent fence or construction element would imply a fixed, long-lasting installation rather than a temporary solution. A warning signal for oncoming traffic, while related to safety, serves a different purpose by conveying information rather than physically obstructing access. Thus, the identification of a barricade as a temporary obstruction is crucial in understanding its role in safety and traffic management.
