This description of the One Leg Stand test posted by Massachusetts DWI Lawyer.

Your Massachusetts DWI Lawyer wants you to be well informed. Here is a basic description of the One Leg Stand Test :

• The next scoring factor is using the arms for balance. It must be six or more inches from the side of the body. This distance from the body should be graded conservatively, taking into account the normal position such as in the case of bodybuilders. The arms do not have to be exactly at the side and can be raised slightly without being scored as long as they are less than six inches from the side. 
  
• If the suspect puts their foot down less than three times, they are only given one point for this scoring factor. This can only be scored during the thirty second time frame. The suspect should be allowed to continue from the point of difficulty once the foot is dropped. This test may lose sensitivity if repeated several times. 
  
• The suspect has been instructed to keep watching their raised foot and to count out loud, but these are not scoring factors. They are not scored and no points assessed if the suspect does not follow these instructions. Counting too slow must be corrected by the officer stopping the test after thirty seconds have elapsed. Proceeding beyond thirty seconds may invalidate the test due to the fatigue factor and this being contrary to the design of the test. If the suspect counts too fast, have then continue until thirty seconds have elapsed.
