A field sobriety test typically involves physical tasks like a one-leg stand or walking in a straight line and is designed to assess a person's coordination, balance, and cognitive function. While the specific outcomes may vary, refusing a field sobriety test can lead the arresting officer to suspect intoxication, resulting in a potential DUI arrest and further investigation. Refusal to take a roadside sobriety test can also lead to suspension of the individual's driver's license.
