Contents of the NHTSA SFST Pocket Card
The nhtsa sfst pocket card encompasses detailed sections on each of the three standardized tests, as well as instructions for their administration, scoring, and interpretation.
1. Horizontal Gaze Nystagmus (HGN)
HGN assesses involuntary eye movements as the suspect follows a stimulus.
- Preparation: Ensure the suspect has no medical conditions affecting eye movements.
- Procedure:
- Use a stimulus (pen, finger, or light) approximately 12-15 inches from the suspect's face.
- Move the stimulus horizontally, observing both eyes, noting any jerking or nystagmus.
- Test at three visual angles: 45°, 30°, and 15°.
- Indicators of impairment:
- Lack of smooth pursuit.
- Distinct and sustained nystagmus at maximum deviation.
- Onset of nystagmus prior to 45°.
2. Walk-and-Turn (WAT)
This test evaluates divided attention and balance.
- Preparation:
- Confirm the surface is flat and safe.
- Instruct the suspect on the test procedures.
- Procedure:
- Demonstrate the test.
- Instruct the suspect to take nine heel-to-toe steps along a straight line.
- Count steps aloud.
- On the ninth step, the suspect must turn around and return in the same manner.
- Indicators of impairment:
- Failure to touch heel-to-toe.
- Improper starting position.
- Loss of balance during instructions or walking.
- Incorrect turn or stepping off the line.
3. One-Leg Stand (OLS)
This test assesses balance and attention.
- Preparation:
- Ensure a flat, safe surface.
- Explain the procedure clearly.
- Procedure:
- Instruct the suspect to stand with feet together and arms at sides.
- Lift one foot approximately 6 inches off the ground.
- Count aloud by thousands (e.g., "one thousand one, one thousand two").
- Maintain the position for 30 seconds.
- Indicators of impairment:
- Swaying.
- Using arms for balance.
- Hopping.
- Putting foot down.

Scoring and Interpretation of SFSTs
The pocket card provides detailed criteria for scoring each test:
- HGN:
- Count the number of clues (e.g., lack of smooth pursuit, distinct nystagmus at maximum deviation).
- More clues indicate higher likelihood of impairment.
- Walk-and-Turn:
- Number of cues (e.g., failure to touch heel-to-toe, improper turn).
- Two or more clues suggest impairment.
- One-Leg Stand:
- Count clues (e.g., sway, hopping).
- Two or more clues typically indicate impairment.
The cumulative scoring from all three tests helps officers determine whether a suspect is likely intoxicated, supporting probable cause for arrest.
