Which DUI Test to Choose: Blood, Urine or Breath
As part of California's implied consent law, if you are accused of drinking and driving, you must consent to an evidentiary blood or breath test. This does not mean that you necessarily have to submit to a field sobriety test, however. Now the question is, what DUI test should you choose? Blood, urine or breath?
Urine Tests
Urine tests are not effective means to measure blood alcohol content, and are no longer used in California for that purpose. If an officer suspects that you are driving under the influence of drugs? San Mateo Lawyer you may be asked to take a urine test. Do not volunteer for a urine test; however, do not refuse a urine test if asked to submit to one.
Blood Tests
Blood tests are the most direct, and hence most accurate, measure of blood alcohol levels. Because a blood test allows for multiple tests of the same sample, it is more accurate. If you know that you are intoxicated, do not volunteer to take a blood test, especially if you have already had a field breathalyzer test, as it will only reinforce the District Attorney's case. However, if you are sure that you are not intoxicated but have been brought in under suspicion of DUI, its accuracy will work in your favor and prove the breath test wrong.
Breath Tests
A breath test is the most common field sobriety blood alcohol test. Unless it is an evidentiary breathalyzer machine (E-pass) which is mandatory, we do not recommend you volunteer to take it--or any--field sobriety test if you are intoxicated. At the police station, however, if you are certain that you are legally intoxicated, a breath test may be your best option. It is easier to challenge the validity of the breathalyzer because there is a greater likelihood for a faulty test.
