A roadblock is a temporary installation set up to control or block traffic along a road. The reasons for one could be:
Road construction
Road closing of some kind
Detours
Police chase
Robbery
In peaceful circumstances, they are usually instantiated 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. They were also used in Nigeria in the 90's to take money from unsuspecting tourists.
