It is important to keep in mind that an arrest for a DUI in Castle Rock or Douglas County can happen to anyone who drinks or uses drugs and drives. It is likely that you know someone else who’s had a DUI arrest. The Castle Rock Police Department averages more than 150 DUI arrests per year, and the Douglas County Sheriff averages 355 DUI arrests per year. The 18th Judicial District (Douglas, Arapahoe, Elbert, and Lincoln Counties) has the third highest number of DUI filings in the state. So, while you may feel embarrassed about your DUI arrest, you are not alone. Kevin Churchill has 25 years of experience handling DUI cases for regular people just like you who have been charged with DUI or DWAI.

DUI Laws in Colorado

The DUI laws in Colorado have changed in recent years, to increase the penalties for people who are convicted of DUI. Therefore, it is critical that you hire an attorney who focuses on DUI cases to get the best representation possible. All DUI convictions have mandatory jail sentences, and the loss of your driver’s license, so the penalties can be very real and quite significant. DUI cases have specialized, technical evidence that is unique from other criminal cases, so having an attorney who specializes in this type of case is paramount. We have been the attorneys for thousands of people in Colorado charged with DUI or DWAI for impairment by alcohol, marijuana, or other drugs. If you are charged with a DUI in Castle Rock, please call us as early as possible to discuss your case. The earlier you have an expert attorney working on your case, the better we can help to guide the process.

Castle Rock DUI Attorney

Driving under the influence charges involve unique evidence and unique laws that are entirely different from other types of criminal cases. Experienced DUI defense involves knowing the science behind the blood and breath tests, as well as knowing the correct way to perform the standardized procedures in the Field Sobriety Tests. Not only does a DUI attorney need to be an expert in criminal law, but they must have expertise with other laws specific to DUI cases, including whether the traffic stop was legal, whether you were given the correct choices for chemical tests, whether the officer gave you the correct advisements, and what evidence can be used against you.

Our goal is to help to minimize the effects that your’ Driving Under the Influence (DUI) or Driving while Ability Impaired (DWAI) arrest has on your life by working to get you the best outcome possible in your case.

The negative effects of getting a DUI should not be understated. You can go to jail, incur significant financial expenses, lose your job, and lose your driver’s license. When possible, we will try to help you to avoid any conviction. If that is not possible, we will then work to help to minimize the legal penalties that you will face. Every DUI conviction leads to a revocation of your driver’s license, but there are ways to get your license reinstated early. There are also options for being able to work at your job while serving your jail time, which is hugely important as it may help to keep you from losing your job. A criminal lawyer who specializes in DUI cases can help you to navigate these complicated factors in your case. If you are facing charges for Driving Under the Influence or Driving While Ability Impaired, it is important that you talk with an attorney who specializes in DUI cases as soon as possible.

DUI Penalties

When convicted of a DUI, this is a criminal conviction, so you could face substantial jail time, significant fees, and be required to get drug or alcohol treatment. You may also face additional criminal charges, such as child abuse if you have a minor in the car at the time of the offense, or vehicular assault if you had an accident and someone was injured. The severity of the penalties can vary based on the details of your case. A skilled and motivated DUI attorney will work to get your penalties reduced, or even have your charges themselves reduced or dismissed. Research shows that people who hire private attorneys for their DUI cases have better chances of having their charges reduced or dismissed, compared to those who have a public defender or who choose to represent themselves.

Colorado DMV and Your Driver’s License

The Colorado Department of Motor Vehicles (DMV) manages the revocation of your driver’s license, and their process is separate from the criminal court process. For many people, losing their license is the most overwhelming consequence of getting arrested for DUI. It can make every aspect of life difficult, including getting to work, picking up kids from school, or just getting to the grocery store. If you took a breathalyzer test to measure your Blood Alcohol Content (BAC) at the time of your arrest, or if you refused a blood and breath test, you have 7 days after arrest to request a DMV hearing about the revocation of your license. If you did a blood test, you have seven days after your results come back to request the hearing. If your license is revoked, there are ways to shorten the length of that revocation if you follow certain guidelines. A knowledgeable DUI attorney can help to guide you through this DMV process.

Professional Licenses Affected by DUI Conviction

Some professional licenses have especially significant consequences for having a DUI conviction, examples include:

  • Truck Driver (CDL)
  • Medical Professionals (Nurse, Doctor, Dentist)
  • School Teacher
  • Airline Pilot


There can be a large amount of complicated, technical evidence in DUI cases. A typical criminal defense attorney may not know all the details of laws and evidence in this type of case, so hiring a lawyer who focuses on DUI cases can be crucially important. You need an expert in this specialized field to best guide you in making decisions about the outcome of your case.

Defending Castle Rock DUI Charges

The Cost of a DUI in Denver, Colorado

A DUI can have many costs, both financial and personal. Financially, it is estimated that a DUI in Colorado costs on average at least $12,000. This includes court costs, loss of income, legal fees, treatment costs, ignition interlock device installation, and higher vehicle insurance fees. Furthermore, a DUI may cause you to lose your job, can damage your reputation, and can negatively affect relationships. It is important not to simply plead guilty because you think your case can’t be won. A skilled DUI lawyer may be able to find reasons to have the case against you dismissed, for example, by finding that there was not a legal reason to pull you over in the first place, or by having evidence otherwise suppressed. A lawyer who specializes in DUI cases could also identify if field sobriety tests were done incorrectly, check if there were issues with your BAC test, recognize when evidence was not collected properly, and look for any other abnormalities in the arrest process. Even if your charges aren’t dropped, identifying these issues can allow your attorney to build reasonable doubt in the case against you, which can help them to negotiate for lesser charges, or less severe penalties.
There are other important factors to consider when hiring a DUI attorney. It can be beneficial to have a local attorney who is familiar with the judges and the District Attorneys, to know how to best negotiate with them on your behalf. Our attorneys have been handling DUI cases in Douglas County for over 20 years. You also want your attorney to dedicate the time and attention to your case that’s necessary to find any potential issues in your case, and Mr. Churchill will do just that. He will personally answer all questions that you have, and will use his years of experience to honestly advise you on your case. Please call our office for a free initial consultation.

What Should You Do (or Not Do) in a DUI Arrest?

  1. Do not make statements to the police. You have probably heard police on TV shows say “you have the right to remain silent” hundreds of times. However, if you are pulled over by the Castle Rock police, it really is important to follow this advice. You should be polite and compliant with the officer, but try to respond to their questions with nods and behaviors, not words. Provide the officer with your license and registration as requested, but do not answer their questions out loud. If you do say something, the officer could state in their report that your speech was slurred or otherwise affected by alcohol, even if you were not impaired by alcohol. You may feel that you want to be compliant and tell the officer that you had just one drink, but this actually can be used as evidence that you were impaired while driving. Whenever possible, it is best to just remain silent.
  2. Consult an experienced DUI lawyer as soon as possible. They can give you advice right away about things you can be doing to help your case. If you hire an attorney, it can take weeks for them to obtain the evidence from the prosecution. It also takes time for your attorney to review video from your arrest. For all these reasons, it’s best to get that process started as early as possible so your case won’t be unnecessarily delayed or negatively affected.
  3. Be sure to request a DMV hearing right away. If you took a breath test or refused to do any BAC test, you have 7 days from your arrest to request this hearing. If you had a blood test done, you must request the DMV hearing within 7 days of getting those results (which can take months). Why is the DMV hearing important for your criminal case, if they are not directly related to each other? Your attorney can question the officer about the details of your case at the DMV hearing, to gather a preview of what they would say in the criminal proceedings, and find potential issues in their testimony to help your case. When you request the hearing, you should choose the option to have the arresting officer to be present at the hearing. Furthermore, if the police officer fails to show up at the hearing, you will win the DMV hearing automatically. And, of course this hearing gives you the chance to possibly keep your driver’s license, which is critical for most people in Castle Rock.
  4. Do not plead guilty, admit guilt, or assume that you will be found guilty. In most cases, there is evidence that can, at the minimum, help to reduce the penalties against you, and in some cases can even lead to charges being dismissed. You need a seasoned DUI attorney to review your evidence and convince the prosecution and judge about the merits of your case. For a free initial consultation, please call Summit DUI Attorneys right away. We handle DUI and DWAI cases in Castle Rock, Highlands Ranch, Parker, Lone Tree, anywhere in Douglas County, and in neighboring counties including Jefferson County and Arapahoe County.
