The five field sobriety tests:
- A horizontal gaze nystagmus test. The driver is asked to follow the lighted red tip of a pen with his eyes, without moving his head. If a driver has been drinking his eyes will jerk, instead of following the light smoothly.
- The nine steps test. The driver must walk a straight line heel-to-toe for nine steps, make a tight turn, and walk back nine steps.
- Balancing on one leg. The driver stands on one foot for about 30 seconds.
- Touching the nose. With hands at his side, the driver is asked to close his eyes, lean his head back, and touch his nose with the tip of each finger.
