![]() If a police force does not have these testing devices, a more complicated routine is necessary. With a portable and quick breathalyzer test, the police can test all drivers (if the law permits) for their breath alcohol content (BrAC), and process the cars one by one as if in a conveyor belt. A roadblock stop is quick action spot for police as well as security personnel. ![]() Checkpoints are also often set near the exit points of public events where people have been drinking to prevent large numbers of drunk drivers from being released into traffic simultaneously from the event. They are often set up late at night or in the very early morning hours and on weekends, and on holidays associated with parties (e.g., New Year's Eve) at which time the proportion of impaired drivers tends to be the highest. Sobriety checkpoints or roadblocks involve law enforcement officials stopping every vehicle (or more typically, every nth vehicle) on a public roadway and investigating the possibility that the driver might be too impaired to drive due to alcohol or drug consumption. Sobriety checkpoints set up by the German Police In some war zones, soldiers working at these checkpoints can be severely injured or killed if one of the vehicles they are searching contains a suicide bomber who detonates his or her bomb or if one of the occupants fires upon soldiers. ![]() Random checkpoints are a common tactic used by many military forces, and have been recently used by UN forces in Kosovo, the Israeli army in the West Bank and US forces in Iraqi Kurdistan, and Iraq in search of insurgents, fugitives, and other law breakers. įlying roadblocks and checkpoints are usually established for no more than a few hours, in order to decrease the possibility of insurgent attacks on them, as well as to maintain their effectiveness as a surprising, unexpected obstacle. When large geographical areas need to be monitored, some types of checkpoint may be quickly airlifted by helicopter from one location to another. Advanced observation posts may also be positioned further out if desired. A random checkpoint must be functional within 15 minutes of the unit's arrival on-site, and establish security teams 50–100 meters on both sides of the area to be controlled. ![]() In some cases, people without proper identification or who arouse suspicion may be refused passage, detained, or arrested. In some countries, soldiers inspect the bottom of the car with a mirror to look for bombs. The trunks of cars are typically searched. Vehicular and pedestrian traffic that approach with the intent of passing flying checkpoints can be asked to produce identification and submit to a search of their persons or vehicle. A reaction force may be designated and concealed nearby. Sentries might be positioned at each end of the checkpoint and are covered by mounted or dismounted machine gun positions. The search area might be the space between multiple vehicles. The vehicles might be positioned to partially or entirely block the road or route. In addition to blocking the road with vehicles, the road may also be partially blocked with concertina wire or heavy objects, such as sandbags or concrete blocks. It might use a large vehicle, or multiple vehicles, such as armored personnel carriers to block the road. The unit establishing a military checkpoint must carry or obtain the materials necessary to construct it. 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.Ī security checkpoint in Nepal, established to check for Maoist insurgents, during the Nepalese Civil War Police also use hastily set up roadblocks to check cars and car trunks when they are pursuing an armed and dangerous fugitive. Patrol car-equipped police units regularly use random checkpoints to detect drivers who are suspected of impaired driving. 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. Random checkpoints are set up to achieve surprise, as opposed to known permanently located checkpoints, which suspects could circumvent. 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.
