The International Association of Chiefs of Police (IACP) Vehicular Pursuit Model Policy states an officer should terminate the pursuit whenever he or she reasonably believes the risks associated with continued pursuit are greater than the public safety benefit of making an immediate apprehension.

Vehicular Pursuit Model Policy
December 2015
The model policy advises to continually evaluate the situation and use the initiating factors as a guide for judging risk and continuing a pursuit.

4. The IACP 2015 Vehicular Pursuit Model Policy states:
The IACP revised their model policy in December 2015.

5. The seriousness of the offense Known information on the suspect

To Pursue or Not Pursue
c. Road configuration (e.g. interstate, divided highway, work zone)
d. Physical location & population density (e.g. residential area, school zone, business district)
Policymakers should consider their own jurisdiction’s environment and enhance the model policy to meet their conditions.

7. e. Existence of vehicular and pedestrian traffic
To Pursue or Not Pursue
e. Existence of vehicular and pedestrian traffic
f. Lighting and visibility

10. When is it Too Risky?
Policy should increase the objectivity and reduce the subjectivity of the decision.

11. The Seriousness of the Offense
What offenses should be pursued? Misdemeanor, traffic, DUI, felony, or violent felony only? Property crimes or crimes against persons?

12. Known Information on the Suspect
Is the driver or vehicle registration identified? Can the person be arrested later?

13. Population Density and Vehicular and Pedestrian Traffic
Are there schools, churches, hospitals, or businesses that create heavy pedestrian or vehicular traffic at certain times? Does rush hour or special events create congestion areas?

14. Road, Weather & Environmental Conditions
Are certain roads unsafe to travel at high speeds such as gravel, t-intersections, dangerous intersections or curves? What impact does weather have on driving conditions on certain roads? Should certain roadways (residential, county, state, or interstate) have speed restrictions?

15. Relative Performance Capabilities of Pursuit Vehicle and Vehicle Being Pursued
Should motorcycles or high performance sports cars be pursued? When should unmarked and non-pursuit rated vehicles be involved in a pursuit?

16. Consider Occupants of Fleeing Vehicle & Civilians in Police Vehicle
Who are the passengers of the fleeing vehicle? Are they teenagers, small children, or elderly? Is the fleeing driver an inexperienced driver? Are prisoners or other civilians in the police vehicle?

17. Thank you for viewing. Please consider our other materials on policy and training.
As a policymaker you should develop predetermined conditions when to engage, driving behavior, and termination of a vehicular pursuit. The policy should have the safety of the officer, fleeing person, and public as top priority.
