tire deflation devices.
06.03.1 POLICY
It is the policy of the Concord Police Department to utilize tire deflation de vices (TDD)
to prevent or end a pursuit in a safe and controlled manner. TDD may be deployed in

other surface, for the purpose of having the device struck by a suspect vehicle in
order to deflate the vehicle ’s tires.

Device specifically desi gned to puncture the tires of a fleeing vehicle, causing the
tires to deflate in a controlled manner and render the vehicle less capable of further
operation.
06.03.3 DEPLOYMENT
A. The use of a TDD shall be authorized by a supervisor.
B. Examples of situations where the deployment of TDDs may be considered:
1. There is reason to believe the suspect has committed an offense justifying
his/her arrest or is in a fresh pursuit under General Order 09.03 Fresh Pursuit of
a Vehicle and;
2. A suspect fails to stop their vehicle after being given notice of command to stop
by blue lights and siren given by an officer or an officer from another agency;
General Order 06.03 TIRE DEFLATION DEVICES (TDD) Page 2 of 3
3. The suspect ignores the obvious and vis ible efforts and warnings to a
reasonable person in the suspect’s position;
4. A TDD may be used to prevent stationary vehicles from being moved in an
attempt to flee;
5. As a pursuit prevention measure for stationary vehicles in situations such as a
high-risk warrant service.
C. During a pursuit, officers shall coordinate with other officer(s) and/or agencies
deploying a TDD or assisting in a pursuit in order to ensure the safe and effective use
of the device.
1. When the decision is made to deploy a TDD, pursuit units shall notify the
officer deploying the device as far in advance as possible of the necessity of its
use.
2. The officer deploying a TDD shall be in position at a predetermined location in
sufficient time for proper deploym ent. All pursuit units shall be notified when
the device is in place.
3. All TDDs shall be deployed in accordance with the manufacturer’s
recommendations and Concord Police training guidelines.
4. The officer deploying a TDD shall secure the device immediately after use, in
their patrol vehicle. This includes safely searching the immediate area where
the TDD was used and collecting any spikes or points which may have become
detached.
5. If a Concord Police vehicle is the primary vehicle in a pursuit while being assisted
by another agency and a decision is made to deploy a TDD, the other agency
shall be informed of the deployment, whenever practicable.
D. Officer safety is the primary consideration when deploying a TDD.
1. Officers shall not place themselves in a location that unnecessarily threatens
their personal safety (e.g., taking a position on the roadway directly in the path
of a fleeing vehicle).
2. Officers shall safely position themselves to elude the suspect vehicle should the
operator take evasive action to avoid striking the deployed TDD.
3. Officers shall choose a deployment location that provides concealment to avoid
being targeted by the suspect vehicle operator.
4. Do not physi cally contact the cord at any time during deployment or other
parts of the device while they are being run over.

A. Prior to utilizing a TDD, officers shall consider:
1. A reasonably safe location for the placement of the TDD;
General Order 06.03 TIRE DEFLATION DEVICES (TDD) Page 3 of 3

2. On vehicles with less than four wheels;
3. On streets with heavy traffic, congestion, or construction;

avoidance.
