To pursue or not pursue? That is the question: modeling police vehicular pursuits

Studies incident‐level pursuit data collected by a large metropolitan police department in the USA over the past decade. Demonstrates that accidents are the outcome of about one‐third of pursuits. Urges that pursuit police should continue to evaluate a pursuit that proceeds into another jurisdiction. Finds that pursuits over borders are more likely to result in an accident; that training may be the most important preventative measure; that accidents are more probable when there is more than one police unit and the pursuit is on a non‐express roadway. Supports past evidence that speed is not a probable indicator of accidents.
