There are several field sobriety tests that can be used by police officers in the state of California to provide preliminary evidence for intoxication in a drunk driving stop. These tests, however, are extremely unreliable and can produce misleading results.

If you were charged with driving under the influence (DUI) of drugs and / or alcohol in California, and a field sobriety test was administered in the course of the traffic stop, talk to a Fullerton DUI lawyer from the Law Offices of Randall T. Longwith about your case as soon possible.


There are a number of v field tests that can be used to help determine whether or not a driver has been operating his or her vehicle under the influence. These tests include:

  • Horizontal Gaze Nystagmus Test — An officer may ask you to follow an object such as a pen with your eyes while keeping your head stationary. Eyes moving back and forth could indicate intoxication.

  • One Leg Stand Test — As the name indicates, this test requires the driver to balance on one foot for a specified period of time.

  • Finger to Nose Test — The officer may ask you to close your eyes, extend your arm, and touch your nose by bending your elbow. This task requires coordination, which is usually impaired by drinking or drug use.

  • Walk the Line Test — In this common test, the officer requests the driver to take nine heel-to-toe steps down a straight line, and then return.

Unfortunately, these tests are far from reliable. If you suffer from certain balance issues, are overweight, or have foot or ankle problems, the walking and standing tests could prove challenging even if you are completely sober.

In addition, the horizontal gaze nystagmus test can be challenging to perform if you are nervous or tired. Learn more about these tests and how an attorney from the Law Offices of Randall T. Longwith could protect your rights.
