a police dog on board, typically just the agency's standard markings with the added notice. Decoy car A decoy car is a police car used to establish a police presence, typically to deter traffic violations or speeding, without a police officer actually being present. They may be older models retired from use, civilian cars modified to resemble police cars, or demonstration vehicles. In some instances, a "decoy car" may not be a vehicle at all, but rather a life-sized cutout or sign depicting a police car. Use of decoy cars is intended to ensure crime deterrence without having to commit manpower, allowing the officer that would otherwise be there to be freed up for other assignments. A drawback of decoy cars is that they cannot actually enforce laws, and motorists that notice that the police car is a decoy can freely ignore it. To circumvent this, decoy cars may be moved to other locations, used alongside traffic enforcement cameras to directly enforce laws, or used in conjunction with hidden police units further down the road to catch motorists that believe they are safe to continue speeding or are flagged for further crimes such as arrest warrants. The use of decoy cars is entirely up to the agency, though in 2005, the Virginia General Assembly considered a bill that would make decoy cars a legal requirement for police. The bill stated in part: "Whenever any law-enforcement vehicle is permanently taken out of service... such vehicle shall be placed at a conspicuous location within a highway median in order to deter violations of motor vehicle laws at that location. Such vehicles shall... be rotated from one location to another as needed to maintain their deterrent effect." Surveillance car A surveillance car is a police car used for surveillance purposes. Usually SUVs, vans, or trucks, surveillance cars can be marked, unmarked, undercover, or disguised, and may be crewed or remotely monitored. They are used to gather evidence of criminal offenses or provide better vantage points at events or high-traffic areas. The surveillance method used varies, and may include CCTV, hidden cameras, wiretapping devices, or even aerial platforms. Some surveillance cars may also be used as bait cars, deployed to catch car thieves. Armored vehicle A police armored vehicle, also known as a SWAT vehicle, tactical vehicle, or rescue vehicle, is an armored vehicle used in a police capacity. They are typically four-wheeled armored
