Being arrested for driving under the influence (DUI) in Colorado can lead to serious consequences, including criminal charges, fines, and the possible loss of your driver's license. However, many drivers do not realize that Colorado law also imposes specific requirements concerning chemical testing when law enforcement suspects impaired driving.
Under Colorado's Express Consent Law, drivers are generally required to submit to an approved chemical test when certain legal conditions are met. Refusing a test can trigger separate administrative penalties, even if the driver is never convicted of DUI. For drivers in Fort Collins, understanding how this law works is essential when facing an impaired driving investigation.
Colorado's Express Consent Law is established under Colorado Revised Statutes § 42-4-1301.1.
The law provides that individuals who operate motor vehicles on Colorado roads are deemed to have consented to chemical testing under specified circumstances.
When a law enforcement officer has probable cause to believe someone has committed an alcohol-related or drug-related driving offense, the officer may request an appropriate chemical test.
Depending on the circumstances, testing may involve:
The law does not mean that police can automatically demand chemical testing during every traffic stop.
Officers must satisfy the applicable legal requirements before invoking express consent procedures.
Our Fort Collins DUI defense attorneys can help drivers understand whether officers followed the proper procedures and what consequences may arise from chemical testing or refusal.
A driver can physically decline a requested chemical test, but refusing a lawful express consent test can result in significant penalties.
Colorado treats refusal as a separate administrative issue from the underlying DUI or driving while ability impaired (DWAI) charge.
For example, suppose a Fort Collins police officer arrests a driver after observing signs of alcohol impairment and developing probable cause for DUI.
If the officer properly requests a chemical test under Colorado's Express Consent Law and the driver refuses, the refusal may trigger driver's license revocation proceedings.
The driver may face these consequences even if the criminal DUI charge is later dismissed.
It is important to distinguish refusing an evidentiary chemical test after an arrest from declining certain roadside testing procedures.
Different legal rules apply depending on the type of test requested and the circumstances of the investigation.
Colorado drivers may encounter more than one type of alcohol-related test during a DUI investigation.
A preliminary breath test, sometimes called a portable breath test, may be requested during a roadside investigation.
For most adult drivers, participation in a preliminary breath test is generally voluntary, and declining it does not automatically trigger the same administrative refusal penalties associated with an express consent test.
However, different rules may apply to drivers under 21.
An evidentiary breath or blood test requested under Colorado's Express Consent Law is different.
These tests are generally administered after an officer has developed probable cause to believe an alcohol-related or drug-related driving offense occurred.
Refusing a properly requested evidentiary test can result in license revocation and other consequences.
For Fort Collins drivers, understanding which test an officer is requesting can be important when evaluating whether a refusal occurred and whether the resulting penalties are legally justified.
Refusing a lawful express consent test can lead to administrative driver's license revocation through the Colorado Division of Motor Vehicles (DMV).
Under Colorado law, the revocation periods for refusing chemical testing generally increase with subsequent refusal violations.
The applicable periods are:
Additional requirements may apply before a driver can regain driving privileges.
A refusal may also result in a persistent drunk driver designation under Colorado law.
This designation can trigger additional requirements involving alcohol education, treatment, insurance documentation, and ignition interlock devices.
For example, a Fort Collins driver who refuses testing during a first DUI arrest may face a one-year revocation period even if the driver has no previous criminal convictions.
Certain drivers may qualify for early reinstatement with an ignition interlock restricted license after satisfying applicable eligibility requirements.
However, early reinstatement is not automatic, and restrictions may continue beyond the initial period of license ineligibility.
Yes. One of the most important features of Colorado's Express Consent Law is that administrative license proceedings are separate from criminal DUI proceedings.
A criminal DUI case determines whether the prosecution can prove the charged offense beyond a reasonable doubt.
An administrative DMV proceeding addresses whether the statutory requirements for driver's license revocation have been satisfied.
For example, a Fort Collins driver might successfully challenge a criminal DUI charge but still face license consequences based on a qualifying chemical test refusal.
Similarly, a driver who submits to testing and produces a result meeting Colorado's administrative alcohol concentration thresholds may face license revocation independently of the criminal case.
The evidence, procedures, and legal standards involved in the two proceedings are not identical.
As a result, drivers should not assume that resolving the criminal case automatically restores their driving privileges.
Yes. Colorado drivers generally have the right to request an administrative hearing to contest a proposed driver's license revocation.
However, strict deadlines apply.
In many express consent cases, a driver must request a DMV hearing within seven days after receiving the notice of revocation.
The exact process depends on the circumstances and the type of notice issued.
At the hearing, relevant issues may include:
For example, if an officer incorrectly characterized a driver's conduct as a refusal, the circumstances surrounding the test request may become important evidence.
A driver who fails to request a hearing within the applicable deadline may lose the opportunity to contest the administrative action through that process.
Because the deadline is short, Fort Collins drivers should seek legal guidance promptly after receiving a revocation notice.
In certain circumstances, yes.
Although Colorado's Express Consent Law establishes consequences for refusing chemical testing, a refusal does not necessarily prevent law enforcement from obtaining evidence through other lawful means.
Depending on the circumstances, officers may seek a search warrant authorizing a blood draw.
Colorado law also contains specific provisions addressing testing in certain serious injury or fatal accident investigations.
However, the legality of a compelled blood draw depends on the applicable statutory requirements and constitutional protections.
The Fourth Amendment generally protects individuals against unreasonable searches and seizures, including certain compelled bodily intrusions.
For Fort Collins drivers, whether officers obtained valid consent, secured an appropriate warrant, or relied on a legally recognized exception may become an important issue in a DUI defense.
For alcohol-related investigations, Colorado law generally provides qualifying drivers with a choice between an approved breath test and a blood test, subject to statutory exceptions.
However, this choice is not unlimited.
For example, if a driver is suspected of impairment by drugs other than alcohol, the applicable testing requirements may differ.
Certain circumstances may also affect whether a particular test is reasonably available or legally appropriate.
An officer's failure to follow applicable procedures concerning test selection may become relevant when evaluating the admissibility of evidence or the validity of an administrative revocation.
However, not every procedural irregularity automatically results in dismissal of criminal charges or reversal of a license revocation.
The legal significance depends on the specific facts and governing law.
Express consent issues can play an important role in both criminal DUI proceedings and administrative driver's license cases.
An attorney may examine the circumstances of the traffic stop, the officer's observations, the arrest, and the chemical testing process.
Potential areas of review include:
Chemical test evidence is often significant in DUI prosecutions, but it is not the only evidence prosecutors may use.
Officers may also rely on driving behavior, physical observations, statements, and other evidence of impairment.
For Fort Collins residents facing DUI or DWAI allegations, an effective defense requires examining the entire investigation rather than focusing exclusively on a chemical test result.
Colorado's Express Consent Law can create serious consequences for drivers who refuse chemical testing or fail an evidentiary alcohol test. Understanding the differences between criminal DUI charges and administrative license proceedings is essential when protecting your driving privileges.
