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 Protests
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.Who Approves of Those Who Block Roads to Protest in the Americas? http://www.vanderbilt.edu/lapop/insights/IO921en.pdfClearing 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, 1 Global Bus.
