Field sobriety tests are carried out to help the police determine whether you are intoxicated. Law enforcement officers rely on these tests to gather evidence to arrest you for a DUI. Field sobriety tests are often conducted when you smell like alcohol or exhibit other signs of drunkenness while driving. However, these field sobriety tests can be inaccurate, either due to improper administration or other external factors.

Below are some factors that can affect the outcome of field sobriety tests:


Getting pulled over by the police can be a frightening experience, especially if it’s your first time. The nervousness may cause you to miss instructions issued before administering the field sobriety test or even compromise the results, leading to wrong conclusions.

Poor instructions

You cannot complete a test without proper instructions. Unfortunately, this is a common reason why most people fail their field sobriety tests. Law enforcement officers tend to have a hard time explaining a complex set of instructions in a short period. It may lead you to perform poorly on the test where you don’t know what you are supposed to do.

Medical conditions

Some conditions may prevent you from completing your field sobriety test. For instance, you may perform poorly based on bad eyesight or a condition limiting physical mobility, such as arthritis. The police may then wrongly conclude that you are intoxicated while, in reality, your medical condition affected the results.

Random factors

Other factors that may affect the results of your field sobriety tests include your weight, age, footwear, and even the weather or the amount of traffic that happens to be moving by the road. All of these can affect your ability to pay attention, your anxiety, your physical balance and more.

A DUI conviction can negatively impact your life in several ways. Your career and reputation may be on the line. As such, it is important to mount a serious defense against the charges you are facing. Knowing more about the law surrounding DUIs can put you in a better place when it comes to protecting your rights and successfully defending your case.
