What is a "roadblock"?

A roadblock is a barrier or obstruction placed on a road to prevent vehicles from passing. Roadblocks can be set up for various reasons, such as during construction, accidents, or security situations. They are often made of barriers, cones, or heavy vehicles that block lanes and force drivers to stop or take alternate routes. Roadblocks are used to ensure safety, control traffic flow, or secure an area, and they can be temporary or permanent depending on the situation.
