Which test helps law enforcement assess a driver's coordination and balance?

The Field Sobriety Test is specifically designed to assess a driver's coordination, balance, and overall physical ability to operate a vehicle safely. These tests often include tasks such as the Walk-and-Turn, One-Leg Stand, and Horizontal Gaze Nystagmus, which directly measure a person's motor skills and cognitive functions.

Law enforcement officers utilize these tests at roadside stops to determine whether a driver may be impaired by alcohol or drugs. The tests provide observable indicators of impairment, making it easier for officers to make informed decisions about a driver's fitness to drive.

In contrast, chemical tests, such as blood or urine tests, measure the concentration of alcohol or drugs in a person's system rather than their physical capabilities. Similarly, breath tests assess breath alcohol content but do not evaluate coordination or balance. Behavioral analysis focuses on a driver's actions and demeanor rather than their physical capabilities. Thus, while all options relate to assessing impairment in some way, the Field Sobriety Test is the direct measure of coordination and balance specifically.
