PIT Maneuver - TPAC

TPAC

Tactical Pursuit And Containment (TPAC) is a term used by police in the United Kingdom, and describes training for managing and terminating police pursuits. TPAC embodies several methods of stopping fleeing vehicles, including rolling roadblocks, use of Stinger spike strips, and the "box and stop" containment method. TPAC is most effective on separated carriageways (such as motorways) where the path of the suspect is limited. It is not suited to roads with frequent cross-roads, those with two-way traffic on a single carriageway, or highways where the suspect may escape by means of a U-turn across the median strip.

Once a fleeing driver is contained on a motorway, a rolling block is initiated ahead of the pursuit. When the pursuit reaches the slowed traffic, the suspect can either attempt to pass the traffic or stay behind it. If the suspect chooses to stay behind the traffic, communication between the pursuing vehicles and the blocking vehicle(s) will lead to the block coming to a standstill, and the vehicle is surrounded and occupants detained. If the fleeing driver chooses to pass the traffic, usually on the hard shoulder, the pursuing vehicles follow it. Once past the traffic, the police vehicles can box in the suspect's vehicle and bring it to a controlled stop through coordinated braking, utilizing the sterile area in front of the blocking vehicle(s) to do so without endangering other road users.

In the UK, TPAC is specialist training given to advanced police drivers. As with the PIT technique, consideration has to be given to the size, weight and center of gravity of the fleeing vehicle. The most commonly used UK police vehicle for TPAC (as of 2007) seems to be the Volvo T-5 V70 Estate, which has found widespread acceptance throughout UK Police forces as a traffic policing vehicle.
