Even when administered under less than ideal conditions, they will generally serve as valid and useful indicators of impairment. Slight variations from the ideal, i.e., the inability to find a perfectly smooth surface at roadside, may have some affect on the evidentiary weight given to the results.

In Missouri, officers are trained to follow the Standardized Field Sobriety Testing (SFST) procedure of the National Highway Safety Administration (NHTSA). The three (3) tests set out in the NHTSA SFST procedure are made part of Missouri's uniform Alcohol Influence Report (AIR), which is completed by officers when they arrest a person for driving while intoxicated (DWI) in Missouri. These tests were developed as a result of research sponsored by the National Highway Traffic Safety Administration (NHTSA) and conducted by the Southern California Research Institute. A formal program of training was developed and is available through NHTSA to help law enforcement officers become more skillful at detecting DWI suspects, describing the behavior of these suspects, and presenting effective testimony in court. Formal administration and accreditation of the program is provided through the International Association of Chiefs of Police (IACP). The three tests of the SFST are: Under normal circumstances, nystagmus occurs when the eyes are rotated at high peripheral angles. However, when a person is impaired by alcohol, nystagmus is exaggerated and may occur at lesser angles.http://gdctogo.com/mae/mm/complete-manual-testing-process.xml

An alcohol-impaired person will also often have difficulty smoothly tracking a moving object. In the HGN test, the officer observes the eyes of a suspect as the suspect follows a slowly moving object such as a pen or small flashlight, horizontally with his or her eyes. The examiner looks for three indicators of impairment in each eye: if the eye cannot follow a moving object smoothly, if jerking is distinct when the eye is at maximum deviation, and if the angle of onset of jerking is within 45 degrees of center. If, between the two eyes, four or more clues appear, the suspect likely has a BAC of 0.08 or greater. NHTSA research found that this test allows proper classification of approximately 88 percent of suspects (Stuster and Burns, 1998). HGN may also indicate consumption of seizure medications, phencyclidine, a variety of inhalants, barbiturates, and other depressants. They require a suspect to listen to and follow instructions while performing simple physical movements. Impaired persons have difficulty with tasks requiring their attention to be divided between simple mental and physical exercises. After taking the steps, the suspect must turn on one foot and return in the same manner in the opposite direction. The examiner looks for eight indicators of impairment: if the suspect cannot keep balance while listening to the instructions, begins before the instructions are finished, stops while walking to regain balance, does not touch heel-to-toe, steps off the line, uses arms to balance, makes an improper turn, or takes an incorrect number of steps. NHTSA research indicates that 79 percent of individuals who exhibit two or more indicators in the performance of the test will have a BAC of 0.08 or greater (Stuster and Burns, 1998). The officer times the subject for 30 seconds. The officer looks for four indicators of impairment, including swaying while balancing, using arms to balance, hopping to maintain balance, and putting the foot down.

NHTSA research indicates that 83 percent of individuals who exhibit two or more such indicators in the performance of the test will have a BAC of 0.08 of greater (Stuster and Burns, 1998). Tharp, Burns, and Moskowitz (1981) reported accuracies of 77 percent for the HGN, 68 percent for the Walk and Turn, and 65 percent for the One Leg Stand components; 81 percent of officers' arrest decisions at 0.10 BAC were correct when all three measures were combined. In contrast, Stuster and Burns (1998) found greater accuracies in making arrest decisions on the basis of SFST results in their study at 0.08 percent BAC, as described previously and summarized in the following table.

During the walk and turn test, the suspect is ordered to take nine heel-to-toe steps along a straight line. 2 After taking nine heel-to-toe steps, the suspect is then directed to turn on one foot and return in the same exact manner in the opposite direction. 3 Law enforcement officials look for eight indicators of impairment when administering the test: if the suspect cannot keep his or her balance during instructions, starts too soon, stops while walking, doesn’t touch heel-to-toe, steps off the line, uses arms to balance, performs improper turn or turns incorrectly, or takes an incorrect amount of steps. 4 According to the National Highway Transportation Safety Administration (NHTSA), studies have revealed the walk and turn test to be 68% accurate in determining whether a driver has a blood alcohol concentration of 10. or greater. 5 NHTSA has formulated particular procedures for officers to follow when overseeing the walk and turn test, as well as specific clues to look for in scoring the test. The other two standardized field sobriety tests are: the horizontal gaze nystagmus test ( HGN ) and the walk and turn test. These three tests are considered “standardized” as a result of several scientific studies establishing with statistical significance the correlation between the three tests and DUI impairment. 9 Nonetheless, both standardized and non-standardized FSTs are used by law enforcement officials to back their DUI investigations. These non-standardized FSTs include the finger-to-nose test, the finger count test, the Rhomberg balance test, and the hand pat test.

Out of the three standardized field sobriety tests, the walk and turn test has proven to be the second most reliable SFST, being 9% less accurate than the HGN test. 10 The walk and turn test is one of three NHTSA standardized field sobriety tests. Nevertheless, the walk and turn test has been and continues to be validated through NHTSA’s research program. Therefore, it still carries a great deal of weight, especially when juxtaposed to the above-mentioned non-standardized field sobriety tests. However, as noted by our California DUI defense lawyers in subsection five, the walk and turn test may very well be a critical source of deception and error in DUI investigations. 2. Walk and Turn Test Instructions Below are the walk and turn test instructions given by the National Highway Traffic Safety Administration (NHTSA). These instructions are given to DUI law enforcement officers during their training so that they may correctly administer the walk and turn sobriety test once out in the field: STEP 1: For standardization in the performance of this test, have the suspect assume the heel-to-toe stance by giving the following verbal instructions, accompanied by demonstrations from a position of interrogation (that is, with your weapon away from the suspect) STEP 2: PLACE YOUR LEFT FOOT ON THE LINE (real or imaginary) Demonstrate this to the suspect STEP 3: PLACE YOUR RIGHT FOOT ON THE LINE AHEAD OF THE LEFT FOOT, WITH HEEL OF RIGHT FOOT AGAINST TOE OF LEFT FOOT Demonstrate this to the suspect (officer should not look at his feet when conducting the demonstration-Officer Safety) STEP 4: PLACE YOUR ARMS DOWN AT YOUR SIDES Demonstrate this to the suspect STEP 5: MAINTAIN THIS POSITION UNTIL I HAVE COMPLETED THE INSTRUCTIONS. DO NOT START TO WALK UNTIL TOLD TO DO SO At the end of the count or after about 30 seconds, if the count is slow, tell the person to put his foot down-if necessary STEP 6: DO YOU UNDERSTAND THE INSTRUCTIONS SO FAR.

Make sure the suspect indicates understanding. STEP 7: WHEN I TELL YOU TO START, TAKE NINE HEEL-TO-TOE STEPS, TURN, AND TAKE NINE HEEL-TO-TOE STEPS BACK Demonstrate three heel-to-toe steps STEP 8: WHEN YOU TURN, KEEP THE FRONT FOOT ON THE LINE, AND TURN BY TAKING A SERIES OF SMALL STEPS WITH THE OTHER FOOT Demonstrate this to the suspect STEP 9: WHILE YOU ARE WALKING, KEEP YOUR ARMS AT YOUR SIDES, WATCH YOUR FEET AT ALL TIMES, AND COUNT YOUR STEPS OUT LOUD STEP 10: ONCE YOU START WALKING, DON’T STOP UNTIL YOU HAVE COMPLETED THE TEST STEP 11: DO YOU UNDERSTAND THE INSTRUCTION. Law enforcement officials specifically focus on the clues listed below as indicators for whether or not a suspect has a BAC of 0.10 percent or more. In scoring this test, law enforcement officials are trained to give only one point for each item observed (even if it is observed more than once) with a maximum score of 9 points. If the DUI suspect scores two or more points on this test, officers are to classify his or her BAC as above 0.10 percent. Using this field sobriety test, an officer will be able to correctly classify about 68 percent of suspects with respect to whether they are drunk driving. The decision point on the Walk-and-Turn Test is simply two of the below-mentioned nine clues. The officer is not to score this item if the suspect sways or uses his arms to balance but maintains the heel-to-toe position. Other aspects of not listening to the instructions are to be included in other clues. CLUE 6: Use arms to balance- The suspect raises one or both arms more than six inches from his sides in order to maintain his balance. In particular, there are three main test conditions that law enforcement officials must keep in mind: Surface Settings: The walk-and-turn test should be given on a reasonably dry, hard, level, non-slippery surface, and under conditions in which the DUI suspect would not be in danger of falling.

There should be sufficient room for the suspect to complete nine heel-to-toe steps. If these guidelines cannot be adhered to at the place where the supsect is stopped, then the law enforcement official should try to move the suspect to a better location. 13 Demarcation Settings: The Walk-and-Turn Test requires a line that the suspect can see. If a natural line is not present, the officer is to draw one in the dirt with a stick or on the sidewalk with chalk. Walking parallel to a curb is also adequate. 14 Light Settings: The officer should further make sure that adequate lighting exists. If the suspect can see the officer fairly well, then the lighting should be determined to be adequate. If the lighting is not adequate, then the officer should use a flashlight to illuminate the ground. In total darkness, the walk and turn test result may be deemed invalid. 15 5. Walk and Turn Test Reliability According to government studies, the walk and turn test is 68% accurate in determining whether a driver has a blood alcohol concentration above.10. 16 Hence, nearly one out of three people who fail the test are not drunk driving. This percentage rate is based on the supposition that the walk and turn test is given correctly in accordance with NHTSA guidelines. In reality, however, not only does the test carry its own inherent defects, but its administration by law enforcement officials, including the California Highway Patrol (CHP) and the Los Angeles Police Department (LAPD), often dip below NHTSA standards. According to Ventura County DUI lawyer 17 John Murray, “the reliability of the walk and turn test is certainly debatable. Furthermore, the officer is supposed to remain as motionless as possible during the test so as not to interfere with it. If an officer, however, decides to walk around or exhibit any other forms of distractive behavior during the testing, then the test results will be all the more dubious. 20 4.

Unfitting attire: A suspect should be allowed to take off her heels if they are more than two inches high at the time of the test. If the officer does not give the suspect the opportunity to remove the shoes, then any test result may be deemed invalid. We can provide a free consultation in office or by phone.

There are certain non -standard field sobriety tests (FSTs) that a law enforcement officer may use while a motorist is still seated in his car to determine if the motorist was driving while intoxicated (DWI). These tests include: (1) the ABC test; (2) the Finger to Nose Test; (3) the Backwards Count test; and (4) the Finger Count Test.

Further, there are three tests that have been approved by the National Highway Traffic Safety Administration (NHTSA) that can be used by a law enforcement officer to determine if a motorist is intoxicated after the motorist exits the vehicle. These tests are known as standardized field sobriety tests (SFSTs) and are approved by many courts in determining intoxication. Those tests are: (1) the horizontal gaze nystagmus test (HGN); (2) the walk-and-turn test (WAT); and the one leg stand test (OLS).This test divides the motorist’s attention between concentrating on actually saying the letters correctly and recalling on which letter to begin and which letter to end. Divided attention tests are simple and indicative of possible impairment because it is difficult for an impaired driver to handle multiple tasks at once. The officer then instructs the motorist to touch the tip of his nose with his index finger, only bending his arm at the elbow and keeping the upper arm out to the side. The motorist should touch his nose with the hand that the officer calls out loud. The officer should never request that the starting and stopping points are numbers which end in 0 or 5, as these are very easy to recall. Instead the numbers should be more random, such as instructing the motorist to count backwards from 58 to 43. This test also divides the motorist’s attention between concentrating on correctly counting backwards while trying to remember where to begin and end. To clarify, the fingers and numbers should coordinate as pointer finger-one, middle finger-two, ring finger-three and pinky finger-four. Also, the officer must not have the subject face the flashing lights of the police cruiser or the headlights of passing cars as this has the potential to induce other types of nystagmus. The subject can be either sitting or standing for the administration of the HGN test.

Although the removal of contact lenses is NOT required, officers are taught to note if the subject is wearing contact lenses and which type, hard or soft. Hard contact lenses could possibly pop out when the eye is moved as far to the side as possible. Removal of eyeglasses makes it easier for an officer to observe eye movement. It should be noted that the wearing of either eyeglasses or contact lenses does not affect the HGN test or results in any way. The eyes are checked for equal pupil size, resting nystagmus (jerking of the eyes as they look straight ahead), and equal tracking (can the eyes follow an object together?). The procedure to check for a medical impairment is for the officer to position a stimulus, such as a pen or finger approximately 12-15 inches from the motorist’s nose and slightly above eye level. The stimulus is positioned in this location to enable the motorist’s eyes to open further and makes it easier to observe the eye’s movement. If the pupils are not equal in size, this could indicate a head injury. If resting nystagmus is observed, this could indicate a pathological disorder, such as brain damage, or a high dose of a Dissociative Anesthetic Drug, such as PCP, and the officer should proceed with extreme caution. To observe equal tracking, the officer first instructs the motorist to follow the stimulus with his eyes only and to keep his head completely still. If the motorist is having difficulty keeping his head still during the test, the officer should instruct the motorist to hold his own head still by pressing the palms of his hands to his cheeks or to hold his own chin. Now the officer checks for equal tracking by moving the object smoothly but quickly across the subject’s entire field of vision to see whether the eyes are following the object simultaneously. If the eyes do not track together, this could indicate a possible medical impairment or injury.

If the motorist exhibits any of these indicators, the officer needs to be cognizant of a possible medical disorder or injury which could require foregoing the HGN test and seeking medical assistance. The 3 clues which indicate impairment are “lack of smooth pursuit”, “distinct nystagmus at maximum deviation”, and “onset of nystagmus prior to 45 degrees”. The officer checks the left eye for the first clue then checks the right eye for the same clue before moving onto the next clue. While moving the stimulus, the officer is looking at the motorist’s left eye to ensure that it is able to pursue the stimulus smoothly. To check the right eye, the officer now moves the stimulus to the left, back across the motorist’s face at the same rate of speed continuing to the right ear. The officer is now checking the right eye for smooth pursuit. If there is a “lack of smooth pursuit”, the officer notes for which eye the clue was observed. This concludes two of the six clues. To check the left eye, the officer moves the stimulus towards the motorist’s left ear until the eye has gone as far to the side as possible. This is very similar to the procedure used for “lack of smooth pursuit”, except in this clue, the eye is held at maximum deviation for a minimum of four seconds and the officer is looking for a “distinct AND sustained” nystagmus. The officer then moves the stimulus all the way across the motorist’s face to check the right eye, again holding the stimulus at maximum deviation for four seconds. If observable, the officer notes a distinct and sustained nystagmus at maximum deviation in each eye. This concludes four of the six clues for HGN. The officer then moves the stimulus towards the motorist’s left shoulder at a speed that would take approximately four seconds for the stimulus to reach the motorist’s shoulder. The movement of the stimulus is substantially slower in this clue.

The officer will be intently watching the left eye for any sign of jerking prior to the stimulus reaching 45 degrees from the center of the motorist’s face. If jerking is noticed, the officer will stop moving the stimulus and verify that the jerking continues at that point. This angle is usually determined by the officer checking to see that some white of the eye is still visible on the side of the eye that is closest to the ear. Another way officers determine 45 degrees from the center of the motorist’s face is at the point where the stimulus is in front of the inside tip of the subject’s shoulder. This is the last two of the six clues for HGN. This is similar to “distinct nystagmus at maximum deviation” except the stimulus is moved vertically instead of horizontally. A divided attention test requires the subject to concentrate on two or more things at once. A divided attention test is a good SFST because driving is a divided attention task. Drivers must simultaneously control steering, accelerate and brake, react to obstacles in the road, and perform a multitude of other tasks. It is very difficult for someone to divide his attention when impaired. The key to an effective divided attention field sobriety test is simplicity. The Walk-and-Turn is a test that is reasonably simple for an average person to perform while sober and requires the subject to do two things at once, making it simple while dividing the subject’s attention. The Instructions stage begins with the officer instructing the motorist to assume a heel-to-toe stance on a real or designated imaginary line. In an effort to standardize all testing procedures and make the instructions absolutely clear, the officer must demonstrate the stance while instructing the motorist to place his left foot on the line. Next, the officer instructs the motorist to place his right foot on the line ahead of the left foot, with the heel of his right foot against the toe of his left foot.

Again the officer needs to demonstrate. The motorist is then instructed to place his arms down at his sides and this task is again demonstrated by the officer. The officer now instructs the motorist to remain in this position until the instructions are completed and the officer emphasizes that the motorist may not start to walk until told to do so. The officer then confirms that the motorist clearly understands the instructions up until this point and also verifies that the motorist indicates his understanding of the instructions. This position is the initial position which is to be maintained throughout the testing instructions. After assuming the correct position, the officer will continue with the actual testing instructions. This divides the motorist’s attention between balancing and listening to and remembering the remaining instructions. The Walking stage divides the motorist’s attention between walking heel-to-toe, counting out loud and recalling the number of steps and the manner in which to make the turn. When instructed to start walking, the motorist is to take nine heel-to-toe steps, turn and take nine heel-to-toe steps back. The officer should demonstrate by taking three heel-to-toe steps. When it is time for the motorist to turn around, he is instructed to “keep his front foot on the line and make a series of small steps with the other foot” in order to make the turn. The officer demonstrates how the turn is to be completed. The motorist is then instructed to keep his arms at his sides, watch his feet at all times and to count his steps out loud, while he is walking. The motorist is instructed that once he starts walking, he is not to stop until he has completed the test. The officer then asks the motorist if he understands the instructions and verifies that the motorist clearly understands. Lastly, the officer instructs the motorist to begin taking his heel-to-toe steps and to count his first step as “one.
