Unvalidated but common Connecticut DUI field tests:
This divided attention test requires a person to count out loud a set of numbers in reverse order. For example, the person is instructed to count starting with 56 and ending with 28. This divides the person’s attention because they have to remember what number to start with, count backwards correctly, and remember what number to stop on. Anything other than 100% perfection will be viewed as a sign of intoxication.
This test requires a person to recite a portion of the alphabet. For example, the person is instructed to start with a specific letter, D, and stop at a specific letter, T. This divides the person’s attention because they have to remember the specific letter to start with, say the letters in sequence, and remember the letter to stop with. Anything less than 100% perfection will be viewed as a sign of intoxication. It is also used to determine if a person is slurring their words.
This test required a person to touch the tip of each finger in succession to the tip of their thumb, up and back, while counting 1, 2, 3, 4, .. 4, 3, 2, 1. They must touch fingertips while not counting out of order. Anything less then 100% perfection will be viewed as a sign of intoxication.
Stationary Balance (i.e. Rhomberg)
This test requires a person to stand with heels and toes touching, leaning their head back to look up at the sky or ceiling, holding their arms out to the side (like an airplane) and estimate 30 seconds. The officer is looking for any unnatural sway. I have had officers testify from a range of anything more than ½ inch to one inch from center is too much sway and must be caused by intoxication. Also, if your estimation is not close to 30 seconds, this will be viewed as a sign of intoxication.
