Specialized Patrol Units

Within the Patrol Division there are several specialized units:

Care Trak System Unit


This unit uses telemetry tracking for "high-risk" people with Alzheimer, dementia, and special needs kids with autism, Down syndrome, etc. Specially trained Deputies work in conjunction with a program provided by Care Trak International, Inc. to provide this service to our county.

Directed Patrol Unit


The Directed Patrol Unit is a multi-faceted unit whose primary goal is conducting criminal interdiction, investigations, and arrests focused on drug trafficking and illegal narcotics. Members of this unit are responsible for the identification, investigation, and arrest of individuals, groups, or organizations that pose a criminal threat, in addition to working with local task forces.

Driving While Intoxicated (DWI) Enforcement Unit


This unit is comprised of dedicated officers to enforce DWI enforcement throughout the county. Assignments include state and federal traffic grants, enforcement checkpoints, public speaking engagements and education for impaired driving.

The officers of the DWI Unit are highly motivated individuals with a passion for what they do. They believe strongly in reducing traffic collisions caused by impaired drivers and in making the roadways in St. Charles County a safe place for residences and motorists.

Drug Recognition Expert Unit


A Drug Recognition Expert (DRE) is an officer who has been specially trained to conduct an examination on a person to determine if the person is impaired and, if so, whether the impairment is caused by drug use or by a medical condition. DREs can be used in a variety of ways, from DWI enforcement to internal investigations.

The Drug Evaluation and Classification Program is sponsored by the International Association of Chiefs of Police (IACP) and the National Highway Traffic Safety Administration (NHTSA).

Field Training Officer Unit


The Field Training Officer Program is responsible for the training of new officers, so each is prepared to function as professional law enforcement officers at the conclusion of their training cycle.

The training cycle consists of a minimum of a three-month intensive on-the-job training and daily performance evaluations. Field training officers have the dual responsibility of providing law enforcement service in their assigned patrol zones, as well as conducting training and evaluations for new deputies.

Honor Guard Unit


The Honor Guard was established in 2004 to represent the department at formal public ceremonies, memorial services, and other special law enforcement and public events.

K-9 Unit


The K-9 Unit is comprised of five working "full service" commissioned dogs and their handlers with one supervisor.
