Blood Alcohol Content (BAC) Limits in Oregon

What is the legal BAC limit for drivers in Oregon?

In Oregon, the legal BAC limit for drivers 21 and over is 0.08%. For drivers under 21, the legal BAC limit is 0.00%, meaning that any detectable amount of alcohol in the blood is considered illegal.

How is BAC measured, and what methods are used for testing in Oregon?

BAC is measured through a breathalyzer test, or with a blood or urine sample. In Oregon, breathalyzer tests are the most commonly used method of testing for blood alcohol content. The breathalyzer measures the amount of alcohol in the air exhaled from the lungs, and police officers use this device to check for levels of impairment. Urine tests can also be used to measure BAC levels, but are not as reliable as breathalyzers. Blood tests for BAC are generally considered the most accurate method of testing, but they are also more expensive and intrusive than other methods.

A person who fails a field sobriety test or has a BAC over the legal limit may be arrested for DUI.

Can medical conditions or medications affect BAC test results and DUI charges in Oregon?

Yes. Certain medical conditions, including diabetes, can cause false positives on Breathalyzer tests, as can certain medications. Additionally, some people who have been drinking may have a natural higher blood alcohol content due to their physiology, which can also lead to an inaccurate test result. In Oregon, an individual accused of DUI can challenge the results of a breath test by providing evidence of a medical condition or medication that could affect the accuracy of the reading. However, it is important to note that this defense may not be successful in all cases. Ultimately, it is up to the court to determine whether a medical condition or medication had an effect on the test results.

How do ignition interlock devices (IIDs) factor into BAC-related penalties in Oregon?
