Keeping DUI Evidence Out of Court Can Keep You Out of Jail

You blew it. You were pulled over, given a field sobriety test, and then blew above the legal limit for alcohol on a breath test administered by the officer.

You failed. You were arrested for DUI and taken to the police station where they took a blood test that confirmed the results of the breath test and showed that the amount of alcohol in your bloodstream exceeded .08.

You’re out of luck. With those test results in hand showing that you were driving while intoxicated, Colorado Springs prosecutors have all they need to convict you for DUI and there’s nothing you can do about it.

That is just not true.

If you’ve been arrested and charged with a Colorado Springs DUI, you have rights. You have defenses. You have the ability to challenge the legality of your traffic stop, the constitutionality of your arrest, the validity of the test results, and admissibility of other evidence that form the cornerstone of the prosecution’s case against you.

But it can be complicated. Challenging DUI evidence and getting DUI evidence dismissed requires a thorough knowledge of the law as well as a deep understanding of the science behind the breath, blood, and other testing used by law enforcement to prosecute DUI cases.

Police Can Make Mistakes That Can Make DUI Evidence Inadmissible

That is why it is so important to retain an experienced and skilled Colorado Springs DUI defense lawyer as soon as possible after a DUI arrest. If the police or prosecutors violated your constitutional rights, failed to follow proper procedures, or otherwise broke the rules, your DUI defense lawyer may be able to suppress DUI evidence they intend to use against you.

Quite simply, it is hard for prosecutors to obtain a conviction for DUI without evidence they can use in court.

From the second those flashing lights appear in your rearview mirror, the police have ample opportunity to make mistakes that can undermine their case against you. Any one of these mistakes can be the key to your defense – if your attorney has the tenacity and skill to expose them.

The challenges to the DUI evidence against you can be based on any of the following:

The legality of the stop

Police officers must have a lawful reason to pull you over. If that lawful reason is a simple traffic violation, that doesn’t mean that they can start asking you about or testing you for suspicion of driving under the influence. They must have a probable cause for the stop or a reasonable suspicion that you are impaired. An improper stop can be the domino that knocks the whole case down.

Bad testing

Breathalyzers and other devices used to test for blood alcohol content are notoriously unreliable. Evidence that is unreliable can be suppressed. Improper maintenance and calibration of the device, administering the test improperly, and external factors can all taint the reliability and accuracy of the test results. Your DUI defense attorney can attack the admissibility of test evidence by calling into question:

  • The timing of the test
  • The qualifications and training of the test administrator
  • The maintenance, calibration, and testing of the equipment used
  • The procedures followed
  • Skin preparation
  • Incorrect mixing of testing chemicals
  • Contamination of the device or test samples
  • Independent biological factors that may impact blood alcohol readings such as existing “mouth alcohol,” acid reflux, diet, and breathing patterns.

Failure to advise you of your Miranda rights

If you’ve been arrested for DUI and the police are conducting a "custodial interrogation" (asking you questions designed to solicit incriminating responses), they must advise you of your constitutional rights beforehand. If the officer doesn’t advise you of your Miranda rights, any incriminating statements you make in the absence of such notice may be deemed inadmissible as evidence.
