Question

Quizplus · Accepted Answer

Police conduct field sobriety tests to determine motor coordination, which involves the functioning of the brain stem. The brain stem controls basic life-support functions such as breathing, heart rate, and blood pressure, as well as motor coordination. Alcohol affects the brain stem, which can result in impaired motor function and difficulty with coordination. Therefore, police use field sobriety tests to indirectly test the effects of alcohol on the brain stem.
