Police use a number of techniques to end chases, from pleading with the driver, waiting for the driver's vehicle to run out of gas, or hoping the driver's vehicle becomes somehow disabled to more forceful methods such as boxing in the vehicle with police cruisers, ramming the vehicle, the PIT maneuver, shooting out the tires, or the use of spike strips, though all efforts, many of which pose risk to all involved as well as bystanders, will be aimed at avoiding danger to civilians. When available, a helicopter may be employed, which in some cases, may follow the vehicle from above while ground units may or may not be involved.
