There are field tests used in determining the legality of a DWI charge. One of these tests is the Walk and Turn test. This tests sobriety through proper coordination. A similar test is the One Leg Stand. Another test is the gaze test that determines proper eye coordination. Another is the count backwards test to determine proper mental ability. These are some other test that can be done. However, these tests have built in tolerances or accuracy levels which can falsely result in test failure. For instance, the Walk and Turn test is said to only be accurate 68% percent of the time. Similarly, the One Leg Stand Test is said to be 65% accurate. Also people with medical and/or physical conditions like old age or are overweight cannot be accurately tested by these test.
