Law Enforcement:
Standard Field Sobriety Testing (SFST) and Refresher            

Course Description: The Standardized Field Sobriety Test (SFST) is a series of standardized tests utilized in the field to obtain validated indicators of impairment and establish probable cause for arrest.

Contact: Vonnie Houser ( or 405-239-5173)

Advanced Roadside Impaired Driving Enforcement (ARIDE)

Course Description: This 16-hour course is intended to bridge the gap between the SFST and DRE courses. Participants will learn how to observe, identify, and articulate the signs of impairment related to drugs, alcohol or a combination of both.

Visit the ARIDE website to find out more and to locate a course near you.

Drug Recognition Expert (DRE)

A drug recognition expert or drug recognition evaluator (DRE) is a police officer trained to recognize impairment in drivers under the influence of drugs other than, or in addition to, alcohol.

Course Description: The DRE course is a 3-phase certification process which includes the 16-hour DRE Pre-school, an overview of the DRE evaluation procedures, the seven drug categories, eye examinations and proficiency in conducting the SFSTs. Phase two includes an overview of the drug evaluation procedures, expanded sessions on each drug category, drug combinations, examination of vital signs, case preparation, courtroom testimony, and Curriculum Vitae (C.V.) preparation. At the conclusion of the 7-days of training, the officer must successfully complete a written examination before moving to the third and final phase of training. And, finally, during phase three, the candidate DRE must complete a minimum of 12 drug evaluations under the supervision of a trained DRE instructor. Of those 12 evaluations, the officer must identify an individual under the influence of at least three of the seven drug categories and obtain a minimum 75% toxicological corroboration rate. The office must then pass a final knowledge examination and be approved by two DRE instructors before being certified as a certified DRE.

Special Emphasis Enforcement

Special Emphasis Enforcement

Saturation Patrols

By using a data driven approach, specific areas that have been identified as high crash locations are selected for saturation patrols. Officers aggressively patrol these areas to locate and arrest impaired drivers. Saturation patrols may be conducted at any time or place with or without prior warning.

Sobriety Checkpoints

Sobriety checkpoints are an effective law enforcement tool involving the stopping of a specific sequence of vehicles at a predetermined fixed location to detect impaired drivers. These operations not only serve as a specific deterrent by arresting impaired drivers who pass through the checkpoints, but more importantly, as a general deterrent to persons who have knowledge of the operation.  Local, county and state law enforcement agencies organize and participate in DUI Checkpoints.

With increased enforcement efforts, well trained law enforcement officers will have zero tolerance for persons driving while impaired. The goal is to have a highly visible ENDUI program that will discourage people who have been drinking or using impairing substances from getting behind the wheel, and to address those who make the poor decision to drive while impaired.

The ENDUI enforcement teams want all of the citizens of the State of Oklahoma to have a safe and enjoyable weekend. If you are planning to drink or if you use any substance that can impair your ability to drive, designate a sober driver, call a taxi, use mass transit, or call a friend or family member. Together, we can ENDUI.


ENDUI Enforcement Teams

ENDUI Enforcement Teams

ENDUI enforcement teams coordinate regional multi-jurisdiction events on a regular basis, including sobriety checkpoints and saturation patrols. Coordinated multi-agency enforcement efforts are needed to impact Oklahoma’s impaired driving problem statewide. The locations of events are driven by state impaired driving crash data and by local request. ENDUI enforcement teams implement activities in support of national highway safety goals to reduce motor vehicle collisions, focusing specifically on impaired driving, and provide assistance to local law enforcement with regard to impaired driving enforcement.

Enforcement teams have access to ENDUI vans, which are mobile command units equipped with instrumentation and equipment needed for effective team efforts in enforcement of Oklahoma Impaired driving laws.  Each van is equipped with an all of the tools and equipment necessary to conduct a checkpoint, including an Intoxilyzer 8000, portable breath testing devices, passive alcohol sensors, mobile kiosks for driver’s licenses checks and vehicle registration verification, safety vests for all officers participating in the checkpoint and all signage needed to announce the checkpoint.

Alcohol related fatalities in Oklahoma continue to represent one-third of all fatalities (OHSO crash facts). The ENDUI enforcement teams work together to combat impaired driving statewide.
