A standardized field sobriety test (SFST) is a test to assist the police officer try to identify an intoxicated driver. There are three SFSTs and they are:
1) the horizontal gaze nystagmous (HGN) test;
2) the one-leg stand test; and,
3) the walk and turn test.
These three tests were developed by researchers through the National Highway and Traffic Safety Administration (NHTSA) and a failure of any of the tests, according to the researchers, is an indicator of the person being under the influence of alcohol. There is a significant on-going debate about the validity, accuracy, and reliability of both the researchers' conclusions and their tests. There is no implied consent requirement that a person submit to a law enforcement officer's request to take these SFSTs or any other police motor skill coordination exercise. No person can be forced to take the FST. For further information, contact your Angelina County DWI Attorney or your Walker County DWI Attorney.
