Chemical Tests vs. Preliminary Breath Tests (PBT)

As a licensed driver in Colorado, you automatically provide consent to a chemical test if you are lawfully arrested for driving under the influence. This is known as Colorado's “express consent” law. This means that, if you refuse to take a breath or blood test, you could lose your driver’s license for one year.

If you refuse a second time, you could lose your license for two years. For your third or any subsequent chemical test refusal after a DUI arrest, you will face a three-year driver's license suspension.

On the other hand, a police officer may ask you to take a roadside preliminary breath test (PBT). If you are at least 21 years old, you may decline this type of test without facing legal consequences. Similar to all field sobriety tests, it’s a tool that helps law enforcement establish probable cause for arrest.

What is a DUI Blood Test?

To press DUI charges, a prosecutor needs ample evidence; a police officer’s statements might not be enough. The collection of more concrete evidence of intoxication can be made possible with a blood test, which is generally taken at a police station after a DUI arrest, but before charges are actually filed.

The results of the blood test will show the suspect’s blood alcohol concentration (BAC). An adult with a standard driver’s license is legally intoxicated with a BAC of 0.08% or higher, which constitutes DUI. A BAC of just 0.05% can also constitute a driving while ability impaired (DWAI) charge in Colorado.

How to Fight a DUI Blood or Breath Test

There are numerous ways to challenge blood or breath test evidence in a Colorado DUI case. In some cases, a law enforcement officer may have failed to properly administer the test, leading to discrepancies in the results. In other cases, it could be possible that the testing device wasn’t properly calibrated.

Another way to challenge a chemical test as evidence against you is to question the justification and legality of the test itself. To get a blood sample from a criminal suspect, law enforcement agencies must first obtain a warrant from a court, which can take many hours or longer in some situations.

In their haste to grab usable evidence, and to not let a suspect sober up, a law enforcement agent might conduct a blood draw and test with no warrant. If this can be proven by your DUI lawyer, you might be able to get all chemical evidence collected against you deemed inadmissible by the court.

Other arguments against DUI blood tests could include:

  • Blood sample was not stored properly, leading to contamination.
  • Test administrator was untrained, causing an abnormally high BAC reading.
  • Testing machine was not maintained or otherwise defective.
