The Different Types of Blood Alcohol Tests and How to Choose One

When you are stopped for suspicion of drunk driving, the police might ask you to take a blood alcohol test. The most common is a breath test commonly known as a Breathalyzer though a new test called a Datamaster is in wide use too. If you refuse, you’ll be asked to submit to a blood draw in order to measure blood alcohol content.

Some law enforcement agents use urine tests too. If you refuse to take any type of blood alcohol test, the arresting officer will assume the worst and so will the court. You are essentially admitting guilt and will likely get the stiffest punishment.

In this Drunk Drivers Rights article we will explain what each blood alcohol test is and if given the choice, which should you choose.

If You Think You’re Under the Limit, Ask for a Blood Test

There are risks in taking any of the tests. A blood test is generally considered the most accurate test. The process is handled by a medical professional and it is believed in the courts that fewer errors are made. In other words, if your blood test shows that you are below the legal limit, that result will likely stand up in court even if you also took a breath test that had you over the limit.

If you Think You’re Over the Limit, Take a Breath or Urine Test

Breath tests are easier to fight in court than a blood test. Good DUI lawyers will be able to determine if the officer administering the test made mistakes that could have led to a false reading. Mistakes involve not calibrating the machine correctly or administering the test incorrectly. Any mistake made by the law enforcement officer might get your case dismissed if your DUI lawyer can expose it.

Urine tests are the least accurate. If you believe you’ve had too much to drink and want to gamble on the test being wrong in your favor, a urine test offers the best chance.

No matter what type of test you’ve taken, if it is after the fact, consult a drunk driving attorney with a proven track record of successfully fighting for drivers and their rights.
