Tennessee treats driving a motor vehicle under the influence of an intoxicant (DUI) as a major offense, says a Nashville DUI attorney, and its law enforcement agents investigate all suspected incidents thoroughly for all available evidence. In their investigations, state and local police first interrogate all suspects before they administer field tests for conclusive evidence.
The interrogation itself is in effect a preliminary test that gives the officer an opportunity to look for objective signs of intoxication in the odor of alcohol or in slurred speech.
Justifications for Interrogation
One reason for interrogating the suspect before testing for sobriety is to determine whether any pre-existing physical impairments preclude use of particular field tests. For example, field sobriety tests of the ability to balance on one leg would not be appropriate for a suspect with infirm or injured knees.
Our Nashville DUI attorney adds that by asking them for the date and time, an interrogation also can reveal whether suspects suffer from any mental impairment from alcohol or whether they can respond rationally with coherence and orientation to time and place. Asking whether they can say why the police stopped them has the same purpose.
Divided Attention Tests
Interrogation before field sobriety testing assesses the suspect’s divided attention ability. Divided attention requires the brain to perform two or more tasks at the same time. Under the influence of alcohol, the tasks become more difficult. Divided attention tasks measure the ability to perform mental and physical multitasking necessary to operate an automobile safely.
Several field sobriety tests divide attention because they require completion of two or more tasks at the same time:
- The walk-and-turn test requires the suspect to perform a difficult physical task while listening to and demonstrating comprehension of compound instructions.
- The one-leg stand test requires the subject to balance on one leg while counting aloud in thousands.
Two different field sobriety tests may combine as in these examples:
- A count-aloud test may combine with touching of the thumb to the fingertips in a finger-count test.
- Walking a straight line may combine with touching the heel to the toes in a walk-and-turn test.
There are also three types of interrogation that intend to divide attention:
- Asking for two things at the same time, both a driver’s license and the vehicle registration, for example.
- Asking questions to interrupt or distract.
- Asking unusual questions.
