How do DPS Troopers determine if someone is fit to drive?

Determining if someone is fit to drive involves a comprehensive assessment of their behavior, appearance, and performance on field sobriety tests. This method enables officers to gather a holistic view of the individual's condition at the time they are stopped.

Behavioral observations might include examining how the driver interacts with the officer, any signs of agitation or confusion, or the presence of slurred speech. The appearance of the driver can also provide important clues; for example, bloodshot eyes or an unsteady stance might indicate impairment.

Field tests, which are typically standardized and may include tasks like walking in a straight line or balancing on one leg, are designed to evaluate motor skills, coordination, and the ability to follow instructions—key indicators of whether the driver is in a suitable condition to operate a vehicle safely.

Together, these elements create a more nuanced and effective approach in determining driver fitness, which goes beyond simply relying on past records or the results from a singular test.
