Field sobriety tests (FSTs)
Standardized tests include the Horizontal Gaze Nystagmus, Walk‑and‑Turn, and One‑Leg Stand. Health issues, footwear, weather, and instructions can affect results. Officers must administer tests per training.
Defense angles
- Non‑standard tests or poor instructions
- Medical or balance conditions
- Uneven or unsuitable surface
- Improper scoring or missing video
Even if you performed poorly, chemical evidence must still be reliable and lawfully obtained.
