Contact with a police officer is always a nerve racking experience. The heart rate accelerates and everyone immediately envisions a higher auto insurance rate. A traffic stop at night can especially heighten the experience because of the bright flashing red and blue emergency lights. If the individual has been consuming alcohol or drugs a traffic stop will quickly become a DUI investigation. Chances are the officer already noted evidence of impairment by observing the vehicle in motion which led to being pulled over for a DUI Stop.
DUI detection training requires the investigating police officer to record all of their observations. During the initial contact with a DUI suspect the officer will note any of the following visual evidence:
1. Bloodshot eyes;
2. Watery eyes;
3. Glassy eyes;
4. Soiled clothing such as spilled drink markings or vomit;
5. Disheveled clothing such as un-tucked shirts or loosened ties;
6. Flushed face;
7. Bruises, bumps or scratches;
8. Failure to locate driver license, insurance or vehicle registration form;
9. Fumbling of driver license, insurance or vehicle registration form;
10. Alcohol containers;
11. Drug paraphernalia or drugs; and
12. Any unusual actions.
The police officer will also use their sense of hearing to detect:
1. Slurred speech or thick tongue speech;
2. Overly loud speech;
3. Repetitive speech;
4. Fast speech;
5. Abusive language;
6. Admissions to consuming intoxicants, alcohol or drugs;
7. Any unusual statements; and
8. Inconsistent statements.
The police officer will also attempt to detect the odor of an alcoholic beverage and marijuana. They must also note and “cover up” odors like breath mints, gum or vehicle air fresheners or any other unusual odors.
Police DUI Interrogation Tactics
During this initial conversation the police officer will employ various questioning techniques. These techniques are designed to evaluate your divided attention ability. An officer will ask for two things simultaneously, such as your driver license and proof of automobile insurance. While performing tasks requested by the officer, they are instructed to ask interrupting or distracting questions. Finally, the officer may ask an unusual question.
These questioning tactics may prompt a DUI suspect to ignore the follow up questions while retrieving the requested driver license. The DUI suspect may supply a “grossly” incorrect answer.
If the police officer’s suspicion is increased during this initial contact, the officer will request the DUI suspect to perform field sobriety tests.
