What is the role of field sobriety tests during a DWI stop?

Field sobriety tests play a crucial role in assessing a driver’s level of impairment during a DWI stop. These tests are designed to evaluate an individual’s physical and cognitive abilities that are typically impacted by alcohol or drugs. The officer observes the driver’s coordination, balance, and ability to follow instructions during various tasks, such as walking in a straight line or standing on one leg.

Successful performance on these tests generally indicates that a driver may not be impaired, while poor performance can suggest that impairment is likely. This objective assessment helps officers make informed decisions about whether to proceed with further evaluation, such as a breathalyzer test or an arrest. By focusing on how a driver performs these specific tasks, law enforcement can gather evidence to support their observations regarding impairment, which is essential in court proceedings related to driving while impaired.

The other options reflect misunderstandings of the primary function of field sobriety tests. They are not primarily intended to confirm identity, facilitate arrests, or provide a basis for fines. Instead, their primary focus is on accurately assessing impairment levels to ensure road safety.
