Field sobriety tests are used by police across the country to establish probable cause for a DUI test. While these tests may not seem scientific, they can be used in a criminal investigation as long as they are performed by an officer with the proper training. Below are the five most common types of field sobriety tests administered by police.

A Guide to Different Types of Field Sobriety Tests

1. Horizontal Gaze Nystagmus Test

Alcohol impairment causes the eyes to jerk or twitch as they move from the left to the right. During this test, an officer will ask you to follow a pencil or light with your eyes as it moves horizontally. If they notice unusual movement, they may ask you to submit to a roadside breathalyzer test.

2. The Walk-&-Turn Test

These tests measure a person’s ability to follow directions and maintain their balance. The officer will ask you to walk heel-to-toe in a straight line, then turn around on command, keeping your arms at your side the entire time. During the test, the officer will likely be looking for swaying, faltering balance, or confusion while following simple instructions.

3. Standing on One Leg

Another common test involves standing on one foot with the other approximately six inches off the ground. The officer will then ask the suspect to count aloud while watching for hopping, swaying, or using your arms for balance. Putting your foot down before being told not to do so can also be considered a probable cause for a breathalyzer test.

4. Finger-to-Nose

The finger-to-nose test is also used to evaluate balance and fine motor control. First, you’ll be asked to stand with your feet together, back straight, and eyes closed. Then the officer will ask you to touch your fingertip to your nose. Being unable to maintain your balance, missing your nose, or stumbling may lead to an arrest for a DUI.

5. The Romberg Balance Test

While it isn’t considered one of the approved field sobriety tests, the Romberg balance test is sometimes used by police to detect signs of intoxication. This test involves standing with your feet together and your eyes closed with your arms at your side. The officer will then ask you to tilt your head back and estimate when 30 seconds have elapsed. The officer will usually be looking for swaying, unusual movement, or an inability to keep your head tilted back.
