Roadblock
A roadblock is a temporary installation set up to control or block traffic along a road.
The reasons for one could be:
- Roadworks
- Temporary road closure during special events
- Police chase
- Robbery
- Sobriety checkpoint
In peaceful circumstances, they are usually installed by the police or road transport authorities; they are also commonly employed during wars and are usually staffed by heavily armed soldiers in that case. During protests and riots, both police and demonstrators sometimes use roadblocks.
