Defending Blood & Breath Tests in DUI Cases

Anytime a person is suspected of DUI (driving under the influence) they may be asked to perform a breath and blood test. Both are tools used by law enforcement to determine whether or not their suspicions are in fact legitimate and a person is legally under the influence of alcohol/drugs. However, a person has the legal right to refuse both tests, but in doing so they can still face DUI charges.

A breath test is generally administered by use of a breathalyzer machine. A person blows into a device that then measures their breath blood ratio which is said to be almost approximate to an actual blood test. A blood test is measured by taking a sample of a suspected person’s blood by use of a needle. A blood test is said to be extremely accurate and is often used to incriminate a person for DUI.

Breath and blood tests are both known to have many faults. Both tests may be administered improperly, contaminated or read improperly. A breathalyzer machine may be calibrated improperly, have a high failure rate and/or may have been poorly maintained. A person who performs a blood test may have poor training that may result in error and/or a mishandling of a person’s blood sample.
