Non-Standardized DUI Tests

Non-Standardized DUI Tests

For those not familiar with the process, a DUI arrest can be very confusing. Your Orange County DUI lawyer can explain the entire process in detail, and evaluate the prosecution’s evidence against you. In some cases, your lawyer may even be able to argue against the inclusion of certain evidence if it is based on a scientifically unproven test.

Standardized vs. Non-Standardized Tests

The National Highway Traffic Safety Administration has standardized three field sobriety tests (FSTs), which are administered during most DUI investigations. Those tests are:

  1. The one leg stand;
  2. The walk and turn; and
  3. The horizontal gaze nystagmus.

However, there are many non-standardized FSTs which are sometimes administered by police officers during investigations.The following are “non-standardized” DUI tests that you may encounter if you are arrested on suspicion of DUI.

  1. Hand writing tests;
  2. Hand pat tests; and
  3. Picking up coins.

Handwriting Test

In a handwriting test, the officer will ask you to write out your name or a line of text. Studies have shown that although changes in handwriting happen at every level of alcohol consumption, those changes cannot be attributed to alcohol alone. Further, other studies suggest that handwriting tests are incapable of determining objectively a particular individual’s blood alcohol level. If you were arrested after a handwriting test was administered, you should consider consulting with an Orange County DUI lawyer about your case.

Hand Pat and Coin Pickup

With the hand pat test, the subject puts both hands in front of them, palms together. You then pat your bottom hand with the palm of your top hand, rotate your top hand, and pat your bottom hand again with the back of your top hand. The officer will tell you when to stop, and instruct you to speed up as you go. Most people inevitably slip up before the officer tells them to stop.

Finally, the coin pickup test involves picking up coins from a flat surface. On the one hand, the test allows subjects with a bad leg or knee to complete a field sobriety test. However, the test itself has never been proven to be scientifically accurate, and so its ability to determine someone’s blood alcohol level is suspect.

If you have been arrested and charged with a DUI, and any of the above tests were administered, you may have a defense. To speak with an experienced Orange County DUI lawyer, call Coffey and Coffey at (800) 706-7888to schedule a consultation.
