The standardized field sobriety test is a series of physical exercises an officer will ask you to perform when you’ve been stopped on suspicion of drunk or impaired driving. These tests are designed to determine a person’s “balance, coordination, and the ability of the driver to divide his or her attention among several tasks at once.” (More information can be found at the NHTSA website). The exercises can include:
- Following a pen or other small object with your eyes: The officer is looking for jerky eye movement
- Standing on one leg for a certain length of time: The officer is looking for inability to balance without lifting arms, swaying, or putting the lifted foot down
- Walking a straight line heel-to-toe and then turning: The officer is looking for an inability to follow instructions, maintain balance, walk a straight line, keep feet together, and stop and start when instructed.
