Before you are arrested for drunk driving, officers need evidence of potential chemical intoxication. When your driving behaviour is erratic, the officers will suspect that you are driving under the influence of alcohol or drugs. The officers will try to confirm whether there is probable cause for a field sobriety test and a potential arrest.
By understanding the various tests that the police will likely perform, you will know how they determine impairment and how you can push back against the police officer’s claims. Some of the tests involve memory, balance and speech. The police may ask you to walk in a straight line and then take 180-degree turn around or balance on one foot.
It is also very likely for the police to interact with you verbally to look for signs of impaired cognitive function like difficulty in remembering information or reaching logical conclusions. Unfortunately, if you have a medical condition, you may fail the field sobriety tests and end up arrested. The only way to pass the field sobriety test while drunk is to practice standing on one foot, walking then turning around and reciting the alphabet backwards.
However, one of the standard tests that you cannot practice for is the horizontal gaze nystagmus test. Police officers usually check the eyes for involuntary movements because motion in your eyes while under the influence of alcohol is an involuntary response. Officers will observe the movement of your eyes when someone turns their gaze to the side. Jerky motions often occur when you are under the influence of alcohol.
One of the reasons that you can use to defend yourself why you struggled with the field sobriety test is a medical condition. Lawyers know about this and they can use it to defend you against pending charges related to the recent traffic stop where you failed the field sobriety test.
