DUI Tests & Evidence

Evidence in DUI Cases

Learn from an Experienced Fresno DUI Attorney

If you have been arrested for DUI, it is essential that you speak with a lawyer from The Law Office of Brian C. Andritch right away. It is vital that you understand you are not guilty until you are convicted or unless you plead guilty. You should never admit to anything, enter a plea, or answer questions until your Fresno DUI defense lawyer is present.

Types of Field Sobriety Tests

There are a variety of different field sobriety tests which a police officer may ask you to do during an arrest. It is important to realize that you are not required to participate in these tests, but you will likely be asked to take a breath or blood test if you refuse. Many of these tests are not standardized and are not proven to be 100% effective, which can lead to less than accurate results.

A few examples of the most common field sobriety tests include:

  • One-leg stand
  • Horizontal Gaze Nystagmus
  • Walk and turn

Blood & Breath Testing for DUI

The breathalyzer is the most common type of testing method used in DUI cases. In order to be accurate, the breathalyzer equipment must be properly administered and calibrated. Even if they are used the right way, there is still a high percent of room for error. There are many factors which need to be taken into consideration, including alcohol absorption and peak alcohol levels. Chemical tests are complex and you may test at a higher level than is accurate.
