In a military context, checkpoints involve the setup of a hasty roadblock by mobile truck- or armored vehicle -mounted infantry to disrupt unauthorized or unwanted movement or military activity and to check for valid identification and search for contraband , fugitives , or weapons that are not permitted in civilian hands. Random checkpoints are set up to achieve surprise, as opposed to known permanently located checkpoints, which suspects could circumvent. They are often established in locations where they cannot be observed by approaching traffic until it is too late to withdraw and escape without being observed. Patrol car -equipped police units regularly use random checkpoints to detect drivers who are suspected of impaired driving . Police also use hastily set up roadblocks to check cars and car trunks when they are pursuing an armed and dangerous fugitive. As with military checkpoints, sobriety checkpoints and fugitive roadblock searches are located in an area where drivers cannot see the checkpoint until it is too late to withdraw, and checkpoints are only set up on a temporary basis.
