What is an SFST Pocket Card?



An SFST pocket card is a small, laminated reference card that summarizes the procedures, clues, and scoring criteria for the three standardized field sobriety tests: the Horizontal Gaze Nystagmus (HGN), Walk-and-Turn (WAT), and One-Leg Stand (OLS). These tests are validated by the National Highway Traffic Safety Administration (NHTSA) and are widely used by law enforcement to estimate a driver's level of impairment.

Key Features of the SFST Pocket Card:
- Compact size, typically 3x5 inches or similar
- Laminated for durability and ease of cleaning
- Clear, concise instructions and criteria
- Visual aids and checklists for each test
- Space for notes or recording observations

Components of the SFST Pocket Card



The pocket card is typically divided into sections corresponding to each of the three standardized tests, with additional sections for general instructions and notes.

1. Horizontal Gaze Nystagmus (HGN)



The HGN test assesses involuntary eye movements that are exaggerated by alcohol or drug impairment.

Procedure Overview:
- The officer holds a stimulus (e.g., pen or small light) approximately 12-15 inches from the suspect's face.
- The officer moves the stimulus horizontally across the suspect's line of sight.
- Observation is made for three clues:
- Lack of smooth pursuit
- Distinct and sustained nystagmus at maximum deviation
- Onset of nystagmus prior to 45 degrees

Scoring and Clues:
- The card lists the number of clues present in each eye.
- The presence of more clues indicates higher impairment.

2. Walk-and-Turn (WAT)



This divided attention test evaluates balance, coordination, and mental focus.

Procedure Overview:
- The suspect is instructed on the instructions and demonstration.
- The test involves taking nine steps along a line, heel-to-toe, turning, and returning.
- The officer observes for clues such as:
- Cannot keep balance during instructions
- Starts too soon
- Stops while walking
- Does not touch heel-to-toe
- Uses arms for balance
- Misses heel contacts or steps off the line

Scoring:
- The card provides specific criteria for each clue and how to record observations.

3. One-Leg Stand (OLS)



This test measures balance and ability to maintain a static position.

Procedure Overview:
- The suspect is instructed to stand on one leg, counting aloud to a specified number (e.g., 30 seconds).
- The officer observes for clues such as:
- Sways while balancing
- Uses arms for balance
- Hopping or putting foot down

Scoring:
- Clues are listed with descriptions to aid in accurate observation.

Using the SFST Pocket Card Effectively



To maximize its benefits, officers should familiarize themselves thoroughly with the pocket card before conducting tests. Here are best practices:


  • Pre-Shift Review: Regularly review the card to stay current with procedures.

  • Practice: Conduct mock tests to reinforce understanding of clues and scoring.

  • Clear Communication: Use the instructions outlined on the card to ensure suspects understand the tests.

  • Accurate Observation: Focus on the specific clues listed, avoiding assumptions or distractions.

  • Documentation: Record observations immediately on the card or in other official documentation.

It's essential that officers understand that deviations from the procedures on the pocket card can be challenged in court, potentially impacting case outcomes.
