A Guide to Field Sobriety Tests

DUI/DWI police officers who are trained to investigate DUIs learn how to conduct five field sobriety tests. They are the Walk-and-Turn, HGN, One-leg Stand, Rhomberg Balance and Finger-to-Nose tests.

These exercises call for one to split attention, perform several tasks simultaneously, and use the ability to remember and perform unusual physical tasks. Police officers spend several hours training on how to administer the tests, and are given sufficient time to practice them. This guide helps educate drivers about field sobriety tests.
