Concrete barrier

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