In Georgia, an officer can ask you to take a field sobriety test if they believe you are not sober. There are two different types: standardized and non-standardized. Today we will take a look at both, along with how officers use these tests on the field. examines both standardized and non-standardized field sobriety tests. While officers use both types, you are more likely to take a standardized field sobriety test. This is because they have a set standard that makes them more viable in court. There are three types of standardized tests and they include: 

  • The one-legged stand 
  • The walk-and-turn 
  • The horizontal gaze nystagmus 

The first test involves standing on one foot with the other elevated about 6 inches from the ground. The second test requires you to walk heel-to-toe in a straight line, turn around and come back. The horizontal gaze nystagmus involves following an officer’s finger or light. It detects tremors in the eye that occur when a person is not sober. Each test checks your motor skills, balance and concentration. Officers will check your ability to follow instructions and how well you carry them out. 

Non-standardized tests have greater variety and a larger margin of error. They can include tests like reciting the alphabet backwards. As these tests to not have agreed-upon standards, they are not conclusive evidence. 

Field sobriety tests are also often used in tandem with other evidence. The results are not always related to a driver’s sobriety. For this reason, test results are not convincing enough to stand on their own as evidence.
