Denver DUI / DWAI Defense Attorneys


Can my case get dismissed?

Possibly. There are many potential ways to fight DUI/DWAI charges. Just five common defense strategies include:

  1. The police administered the field sobriety tests incorrectly.
  2. The breath or blood testing equipment was mishandled or defective.
  3. The defendant's medical condition mimicked intoxication.
  4. Law enforcement had no probable cause for the traffic stop.
  5. The sobriety checkpoint was unconstitutional.

If prosecutors see their evidence is insufficient, they may drop the charge. Or they may reduce it to a lesser offense such as reckless driving (42-4-1401 C.R.S.).

There is also the option of going to trial. As long as the defense attorney can raise a reasonable doubt, the court should acquit the defendant. But in practice, most DUI/DWAI cases resolve through negotiations alone.

Will I lose my license?

First-time DUIs carry a 9-month license suspension. But defendants may contest the suspension at a DMV hearing.

DMV hearings are administrative trials separate from the criminal matter. They are valuable opportunities to cross-examine the arresting officer. And depending on the case, the judge may find in the driver's favor.

Even if the license does get suspended, DUI-1st defendants can usually resume driving after 1 month. They would just need to have an ignition interlock device (IID) installed. This is a breathalyzer that keeps the car from starting if it detects alcohol. Then if the driver uses the IID correctly for 4 months, the license will be fully reinstated.

Note that DWAIs carry no license suspension. Refusing to take a breath or blood test carries a 1-year suspension for a first violation. And drivers under 21 arrested for underage drinking and driving (UDD) face a 3-month suspension for a first violation.

Will I go to jail?

Courts rarely impose jail for first-time misdemeanor DUIs unless the driver's blood alcohol content (BAC) was 0.20% or higher. And it may be possible to get drunk/drugged driving charges lessened or dropped completely.

Otherwise, the sentence depends on whether the charge is for:

  1. DUI,
  2. DWAI,
  3. UDD, or
  4. Felony DUI

How long do DUI cases take?

It varies but on average three-to-six months.

The first step in the DUI court process is the arraignment. This is a short hearing where the defendant is formally charged. But if the defendant has an attorney, he/she can have the arraignment vacated and proceed to a pretrial conference.

The pretrial conference is where the defense attorney negotiates with the prosecutor. The defense attorney will point out all the deficiencies and problems in the case. And hopefully the D.A. will respond by offering a dismissal or favorable plea deal.

If negotiations stall, the court can then set the matter for trial. Sometimes, the very act of trial preparation makes prosecutors realize their case is too weak to sustain a conviction. And they may ultimately give in and drop or reduce the charges.

Can I get the record sealed?

DUI/DWAI convictions may never be sealed under Colorado law. But under certain conditions, convictions for UDD or juvenile DWAI may be expunged.

Note that DUI/DWAI charges that get dismissed can usually be sealed right away. The only exception is if the case was dismissed because of a deferred judgment.

When is DUI a felony?

There are three ways that driving under the influence of alcohol or drugs becomes a felony:

  1. The defendant has three (3) prior convictions for DUI, DWAI, or UDD; or
  2. The defendant's driving caused serious bodily injury (vehicular assault); or
  3. The defendant caused a fatal accident (vehicular homicide)

In addition to the fines and prison time discussed above, felony DUI convictions result in a loss of gun rights.

Is DUI the same as DWAI?

No. DUI stands for "driving under the influence." It typically applies to drivers with a BAC of .08% or higher. Even if they are driving safely, having an illegal BAC level is automatically ("per se") illegal.

Meanwhile, DWAI stands for "driving while ability impaired." This typically applies to drivers with a BAC of at least .05% but less than .08%.

Predictably, DWAI carries lesser penalties than DUI. And unlike DUI, DWAI does not require a mandatory license suspension.

What if I was driving under the influence of marijuana?

Colorado punishes drugged driving identically to drunk driving. The only difference is that drivers suspected of being high are required to take a blood test. They cannot elect to take a breath test instead.

What are the immigration consequences?

DUI generally is not deportable. Therefore, non-citizens convicted of it usually will not be removed from the U.S. once they finish their sentence.

However, immigration law is always changing. Therefore, aliens facing criminal charges are encouraged to consult with an attorney right away. The attorney can help determine whether the case threatens the person's resident status.
