Challenges Faced by Law Enforcement in Winter DUI Stops 
Colorado’s winter months bring a variety of weather-related difficulties for both law enforcement officers and drivers. The snow, ice, and low visibility make it harder to accurately assess whether a driver is under the influence or simply struggling to maintain control due to weather conditions. Several factors contribute to the challenges faced by law enforcement during winter DUI stops:
- Slippery Roads and Winter Conditions: Ice and snow-covered roads are common in Colorado during the colder months, making it more difficult for officers to judge a driver’s behavior. A driver swerving or sliding on the road might appear to be intoxicated, but it could simply be the result of bad road conditions. The slippery surface can lead to false conclusions based on driving behavior alone. Drivers who are just struggling to control their vehicles on icy roads could be unfairly pulled over for suspicion of DUI.
- Reduced Visibility: Colorado winters often bring heavy snowfall, fog, and shorter daylight hours, which can significantly reduce visibility on the roads. When officers are unable to clearly see a driver’s actions or surroundings, they might misinterpret behavior or make an unjustified stop. Poor visibility conditions complicate an officer’s ability to accurately assess driving patterns that may be caused by the weather rather than alcohol or drug use.
- Field Sobriety Test Complications: Field sobriety tests (FSTs) are crucial in DUI investigations. However, when these tests are conducted on icy or snow-covered ground, they are inherently flawed. Standard tests like the one-leg stand or the walk-and-turn are extremely difficult to perform on slippery surfaces, which may cause a sober driver to fail. Cold temperatures can also impact physical coordination, making it harder for individuals to perform well even when sober. These factors can lead to inaccurate or unfair assessments of a driver’s sobriety.

Impact of Weather on Breathalyzer Tests
Breathalyzer tests are a key piece of evidence in DUI investigations. However, the cold temperatures of winter can affect the accuracy of these tests. Low temperatures can impact the calibration of breathalyzers, leading to unreliable readings. Furthermore, individuals may struggle to blow hard enough into the device due to shivering or other cold-induced discomforts. The combination of these factors may make breathalyzer tests less accurate during the winter months, which presents an opportunity for defense lawyers to challenge the results in DUI cases.How Winter Weather Can Affect DUI Cases
The role of winter weather in DUI cases cannot be overstated. Weather conditions not only complicate law enforcement’s ability to accurately assess sobriety, but they can also affect the validity of evidence. Drivers who are pulled over in the winter months may have legal defenses related to the conditions at the time of their stop, including:- Challenging Officer Observations: Officers may misinterpret a driver’s behavior when weather conditions, such as slippery roads or reduced visibility, make it difficult to clearly see what is happening. In DUI defense, attorneys can argue that weather-related factors may have influenced the officer’s decision to pull over a driver.
- Questioning the Accuracy of Field Sobriety Tests: If a field sobriety test is conducted on a surface that is slick, a defense attorney can challenge the results of the test. For example, if a driver fails the walk-and-turn test due to icy conditions, this could be used to argue that the test was invalid or unfairly conducted.
- Challenging Breathalyzer Results: If a breathalyzer reading is affected by the weather or calibration issues, the defense could argue that the results are not reliable. Weather-related factors, such as cold temperatures or shivering, may impair a person’s ability to provide an accurate sample. Legal challenges to breathalyzer results are often a critical part of DUI defense in Colorado during the winter months.

I've had the pleasure of working with Mr. Hanchey on two occasions, and each interaction has been nothing short of exceptional. His professional demeanor, coupled with the outstanding support from his staff significantly alleviated any anxieties I had. I am thoroughly satisfied with the outcomes achieved. Should the need for legal representation arise in the future, Mr. Hanchey will undoubtedly be my first choice.

Mark Hanchey has been excellent. I spoke with him last minute before my court date. He still showed up to court with me and was very caring and helped me before I had even officially hired him. I felt like he cared about me and my case. He knows his craft very well and you can tell that the judge and other attorneys respect him when he is in court. He is also very kind. I recommend him to anyone. An excellent attorney.

I had an amazing experience with the Hanchey Law Firm! Mr. Hanchey got me the absolute best result I could have imagined for my case. I can’t even tell you how many times I’ve heard, “wow, you must have had a really good lawyer!” when discussing the result. I live far from Colorado Springs, but I will forever make the trip for this firm when I need them! Highly recommend!

How Drivers Can Protect Themselves During a DUI Stop in Winter Weather
While winter conditions complicate the DUI process for both law enforcement and drivers, there are steps that individuals can take to protect their rights during a DUI stop:- Know Your Rights: Drivers have the right to refuse certain tests, including field sobriety tests. Although refusing these tests may lead to penalties such as a driver’s license suspension, it can also protect against unfair or inaccurate assessments, especially when weather conditions are involved. Drivers should be informed of their right to refuse these tests and consider the potential consequences before agreeing to them.
- Request Video Evidence: If possible, drivers should request that the interaction be recorded. This can help provide crucial evidence for a defense case, particularly when weather conditions played a role in the officer’s decision to conduct a DUI stop. Video footage can help challenge any claims that the driver was acting suspiciously or failing field sobriety tests due to weather.
- Challenge the Stop: If a driver was pulled over due to weather conditions (e.g., sliding or swerving on icy roads), a skilled attorney can challenge the validity of the stop itself. Officers must have a valid reason to pull a driver over, and if the stop was made based on misinterpreted behavior caused by winter weather, the evidence gathered during the stop could be deemed inadmissible.
Winter Weather DUI Defense Strategies
Experienced DUI defense attorneys in Colorado, such as those at Mark S. Hanchey and Ben Peterson Law Firm, often employ several strategies when defending against DUI charges in winter months. These strategies include:- Challenging Field Sobriety Tests: Winter weather makes it difficult to perform standard field sobriety tests, and defense attorneys can argue that the tests were unfairly administered due to icy conditions. These tests are meant to assess a driver’s physical coordination, but when the ground is slippery or cold, they do not accurately reflect the driver’s abilities.
- Contesting Breathalyzer Results: Breathalyzer tests are often key evidence in DUI cases. In winter, cold temperatures and other factors can affect the accuracy of breathalyzer results. A skilled attorney can challenge the reliability of breathalyzer readings by presenting evidence that winter weather interfered with the test.
- Questioning the Officer’s Observations: Officers may make assumptions about a driver’s behavior that are influenced by winter conditions. Defense attorneys can argue that the officer’s observations were clouded by weather conditions and that they did not have sufficient grounds to pull the driver over or conduct a DUI investigation.
