Standardized Field Sobriety Tests

Standardized field sobriety tests (FSTs) are tests approved by the National Highway Traffic Safety Administration (NHTSA). These tests are allegedly designed to help police determine whether a driver is intoxicated.

There are three standardized FSTs:

1. Horizontal Gaze Nystagmus Test (HGN test)

2. Walk-and-Turn Test (WAT test)

3. One-Leg Stand Test (OLS test)

The results of the one leg stand and the walk-and-turn tests may be used as evidence against you in an OUI case. The horizontal gaze nystagmus test (eye test), however, is generally not admissible at trial in Massachusetts unless a qualified medical expert is brought in to explain the test to the judge or jury.

Non-standardized tests, on the other hand, are not validated by NHTSA but may still admissible as evidence in Massachusetts. It is important to speak with a Massachusetts OUI lawyer about the specifics of your case to determine if there may be a viable motion to exclude these non-standardized tests from evidence at trial.

Non-standardized FSTs include:

  • finger to nose test
  • the finger count test
  • the hand pat test
  • the alphabet test
  • the reverse counting test
  • the coin pickup test
