The Legal Reality of Sobriety Testing
Standardized Field Sobriety Tests (SFSTs) are widely used by law enforcement to assess visible signs of impairment during DUI and DWI investigations. These tests often play a central role in arrest decisions and are therefore heavily scrutinized in both criminal and civil litigation.
When sobriety tests are improperly administered, incorrectly interpreted, or applied outside their validated scope, the results may be unreliable. Determining whether testing procedures were followed correctly—and what those results do or do not indicate—can have significant legal consequences.
