Roadblock Explained

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.^{[1] [2]}
