Breath and Blood Tests

A crucial part of a Portland DUI case will be the chemical test which was used to determine your blood alcohol or breath alcohol concentration. Most often, a driver will be given the choice between a breath test and a blood test. Under Oregon’s Implied Consent law, a driver will face driver’s license suspension for refusing to submit to a breath or blood test. A driver will also face suspension or revocation for failing a blood or breath test (showing a blood alcohol concentration of .08% or greater.)

You need a Portland DUI attorney on your side if you were arrested for drunk driving and refused or failed a breath test or blood test. Not only will you need representation in criminal proceedings for any DUII (driving under the influence of intoxicants) charges that you may face, but you will also need representation at your DMV hearing as well. You have only 10 calendar days from the date of your DUI arrest to schedule a hearing regarding the administrative suspension of your driver’s license. Fail to schedule this hearing and you will face license suspension regardless of the outcome of your criminal case.

Contesting the results of a breath test or blood test is an important part of building an effective DUI defense strategy. It is virtually impossible for these chemical tests to be 100% accurate all of the time, and it is your lawyer’s job to discover what went wrong with your test and how to prove, in court and at your DMV hearing, that the test results were inaccurate.

A skilled Portland DUI lawyer may be able to prove that a breath test or blood test was inconclusive due to:

  • Operator error
  • Equipment malfunction
  • A mishandled blood test
  • An incorrectly administered breath test
  • A breath test machine which is not calibrated properly
  • A physical condition the driver has which may have led to a false high reading
