What Evidence Can a DUI Attorney in Colorado Springs Get Thrown Out?
Driving under the influence (DUI) is a serious offense, and being charged with it can have long-lasting consequences. However, not all evidence presented in a DUI case is automatically admissible in court. With the help of a skilled DUI attorney in Colorado Springs, certain pieces of evidence can potentially be suppressed or dismissed altogether. This can greatly improve the defendant’s chances of avoiding a conviction or reducing penalties.
In this blog, we’ll explore what types of evidence a DUI lawyer might be able to challenge and get thrown out, helping you understand how legal defenses work in DUI cases.
Understanding DUI Evidence and Its Vulnerabilities
Evidence in a DUI case typically includes officer observations, field sobriety tests, breath or blood tests, and dashboard or body camera footage. However, if any of these were collected unlawfully or handled improperly, they may be considered inadmissible in court.
A dui attorney in Colorado Springs will thoroughly examine the evidence against you to identify any weaknesses or legal violations that can be used to have it thrown out. Here are some common types of evidence that may be successfully challenged:
Types of Evidence That Can Be Thrown Out
1. Improper Traffic Stop
For any DUI arrest to be valid, the initial stop must be lawful. If the officer lacked reasonable suspicion to pull you over, any evidence collected afterward might be suppressed.
-
No clear traffic violation
-
Officer relied on a vague tip
-
Stop based on profiling or bias
2. Faulty Field Sobriety Tests (FSTs)
Field sobriety tests can be highly subjective and prone to human error. If they were not administered according to standardized procedures, the results may not be admissible.
-
Poor lighting or uneven surfaces
-
Medical or physical conditions affecting performance
-
Officer’s failure to follow protocol
3. Breathalyzer Test Errors
Breath tests must be conducted with properly calibrated equipment and by trained personnel. Any deviation from these standards can lead to the dismissal of the results.
-
Expired calibration on device
-
Operator not certified
-
Contaminated mouth alcohol (e.g., mouthwash, recent vomiting)
4. Unlawful Blood Tests
In Colorado, blood tests require either your consent or a warrant. If your blood was drawn without consent or legal authorization, that evidence could be suppressed.
-
No search warrant obtained
-
Coerced or uninformed consent
-
Mishandling of blood sample
5. Mishandled Evidence
Proper chain of custody must be maintained from the time evidence is collected to when it is presented in court. Any gap in this process can raise doubts about the reliability of the evidence.
-
Sample not labeled correctly
-
Missing or altered logs
-
Delayed or improper storage
6. Miranda Rights Violation
If you were interrogated after being taken into custody without being read your Miranda rights, anything you said may be inadmissible in court.
-
No clear Miranda warning
-
Questioning after requesting an attorney
-
Statements made under pressure
