This test along with the HGN and one legged stand...when done correctly can spot the impaired driver with a BAC of .10 or higher. Its reasonable to assume that any person who is sober and under the age of 65 can complete or pass these tests.
"Looking at your feet" is a required instruction in the DWI Detection and Standardized Field Sobriety Testing Manual 2006 Edition Session VIII, page VIII-9. The concept in my belief is that if you are looking down at your feet, it is harder to keep your balance because you are not looking at the horizon. Therefore, it is designed to make them fail. However, the manual gives no reason behind this.
@gneeley your so right, many a fellow law school and business school students cannot pass these tests sober. I'm not kidding, this is from multiple grad schools and law schools.
Why would you have your DUI look at his feet? Its not because he might trip or whats the concept behind this? I never tell them to look at this feet. Was there any changes to this test, it so, show me the resource or site.
@ceethat If a person who is trying to balance looks up at the horizon, they can balance better. If the driver is looking at their feet, the inner ear fluid, which alcohol affects will throw the balance off. If your SFST trained..youd know this.
It's very easy to do this or any of these tests in a brightly lit studio room, on a flat surface, with no distractions and no consequences for failure.
It's another thing entirely to do these tests when you have just been pulled over, in the dark, on the road somewhere, the police lights are flashing, the ground is uneven and there is an officer with a flashlight standing just a few feet away with a notepad or clipboard.
Just saying there is the chance of false positives...
Also when i do this demonstration, I tell the subject "do not start the test until I tell you to, and once you start the test do not stop. Do you understand?"
Also, when you do the first 9 steps, and turn around to face the opposite direction, you are supposed to STOP and end up facing the opposite direction with your right foot heel-to-toe in front of your left foot....AND THEN you are supposed to start walking, counting from 1 - 9 out loud.
What you did during the demonstration was turn, and immediately start walking 9 steps.
You ended up with the wrong foot in front of you.
The person doing the actual test, did it correctly though.
I have moderate hypertension(low blood pressure). I often can look like I'm drunk because I can stagger when I walk and look tipsy, and can't stand on one leg(a doctor signed off I can drive fine though). I also have asthma so it's hard, if not impossible, to breath long/hard enough to take a breath test. False breath positives are also found in diabetics, and people with autism/Asperger's may have trouble starring at certain objects. Cops should have portable blood test.
@imanerd36 I was almost killed. I chased the driver down to the point he hit me. Now I am down for DWI and Agrivated assault with a deadly weapon. My life is being turned inside out right now. Nobody was hurt. If inches matter I would have been hurt or dead. I did not pass the field but I passed the office sobriety test. I was shaking for the first and thats that. It was not a fair test at all.
knatwig...I don't know where you served as a juror...but in New Mexico...The New Mexico Implied Consent Act must be read to the suspect. Included in the implied consent is the admonition that the person has a right to an independent test. CA also has this in the chemical admonition.
just finished serving as a juror on a dwi case today... spent 2 days listening to nothing but nhtsa field tests... horizontal gaze nystagmus (i'd be happy never to hear this term again), walk and turn, and one leg stand... remember if you fail a breath test you have the right to an independent blood test by a qualified individual of your choice within 2 hours... police will not inform you of this right

@thatguysaid Exactly. And asking you to follow a pen with your eyes when you cannot even see it because there is the flood lights behind his hand.

@thatguysaid have you noticed the officers can always perform well when they know the tests and what they are looking for beforehand?

@psychoclownboy That would fuck up most sober people.

During the instruction phase, you are supposed to have the subject keep his eyes on you the entire time while you are giving out the instructions.
You also need to demonstrate and tell him to count out loud.
At least that's how we do it. I could be wrong on that.
