DUI Blood Tests: What You Need to Know

In a previous entry, we shared tips for why you should never take a field sobriety test. Spoiler alert: they’re grossly unreliable.

In this issue, we’ll talk about what rights you have in terms of DUI blood tests and what exactly such tests measure.

You Don’t Get To Refuse Blood Tests

Unlike field sobriety tests, if you refuse to submit to a blood test, you can lose your driver’s license immediately.

Sound unfair? It may be but you gave implied consent to be blood tested when you applied for your Arizona driver’s license.

While many police officers have the necessary training to draw your blood, you have the right to go to a hospital of your choice and request that officials there perform your blood test.

Here’s What The Blood Test Is Measuring

A blood test for DUI is all about measuring the concentration of alcohol in your blood or blood-alcohol concentration (BAC).

If your BAC is 0.08% or higher, you’ll be arrested and charged with DUI.

Because we’re all different, there are a few factors that need to be taken into consideration before even guessing how many drinks it will take for someone to reach a BAC of 0.08%. Those factors include your weight and whether or not you had an empty or full stomach when you drank.

How to Get Your License Back if it’s Suspended

If you do lose your driver’s license for not agreeing to take part in a blood test, you could be without it for a year.

You can, however, issue a challenge to the court to retrieve your license. When your license is suspended, you’ll receive documentation with forms on how to challenge the suspension. You’ll have 15 days from receiving the paperwork to make your challenge.
