23 Jun Defenses Against DUI: Part 4
It is important to understand that there are many ways to defend extreme DUI charges. There are a number of constitutional and statutory challenges that attorney Todd Coolidge looks for when he prepares a DUI defense.
The main piece of evidence used by the State during a DUI case is the chemical test. The blood test is usually conducted on a Gas Chromatograph while a breath test is usually administered using an Intoxilyzer.
Both of these types of tests are conducted using a machine and there are a number of rules and regulations that govern the use of these machines. There are also a number of factors that can affect the results these machines produce.
Some of the errors associated with an Intoxilyzer (breath) test are:
- Range of Error
- Variables for the instrument, such as breath patterns, body temperature of the accused, and blood to breath partition ratio
- Operator Error
- Mouth alcohol
- Radio frequency interference
The Intoxilyzer is a machine that has to be calibrated every 30 days, and tested every 90 days to make sure it can catch some of the issues listed above. A thorough investigation of the calibration records and standard quality assurance records is necessary in order to show that the machine is functioning properly and accurately.
