WALK AWAY FROM THE WALK AND TURN TEST
According to government studies, the walk and turn test is 68% accurate in determining whether a driver has a blood alcohol concentration above .10. (Even though current limit is .08)Therefore, 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. However, not only does the test carry its own inherent defects, but its administration by law enforcement officials often dip below NHTSA standards.
RELIABILITY ISSUES WITH THE WALK AND TURN TEST1. Unsuitable Surface settings:
? The walk-and-turn test should be given on level ground, on a hard, dry, non-slippery surface. If these surface conditions are not in place, then the validity of the walk and turn test may be greatly diminished.
2. Impairments related to the mind and/or body:
? If a suspect is elderly (i.e. over 60 years of age) or has certain problems with various parts of the body, namely, knee, back and hip problems or inner ear conditions or is extremely small and/or obese in nature-then these bodily impairments, along with a myriad of others-may incorrectly skew the results towards failure.
? Similarly, if a suspect has mental disabilities and/or brain damage that would inhibit an ability to understand and/or adhere to instructions, then the test results may be deemed invalid.
3. External Distractions:
? The suspect should be able to perform the test away from common roadside distractions such as oncoming traffic and/or sirens/honking.
? 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 more dubious.
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. #refuserefuserefuse
