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
*Car chase, 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.Clearing the Path for Land Rights, One Road Block at a Time: How Peru's Indigenous Population can Assert Their Land Rights Against Peru's Government
