Winter weather is a defining characteristic of Colorado, with snowstorms, icy roads, and frigid temperatures often taking center stage. While these weather conditions bring unique challenges for drivers, they also play a significant role in law enforcement’s ability to administer accurate field sobriety tests (FSTs) when suspecting a driver of being under the influence of alcohol or drugs. At Hebets & McCallin P.C., we understand that the environmental factors impacting your sobriety test results can be critical in determining the outcome of your DUI case.
Field sobriety tests are used by police officers as a way to assess whether a driver is impaired. However, in winter, conditions like snow, ice, and cold temperatures can influence these tests, making it harder to perform the necessary tasks accurately. This can ultimately affect the results, leading to potential inaccuracies that could be beneficial to your defense if you face DUI charges. This discussion dives into the ways in which winter weather in Colorado can impair FST accuracy and the possible legal implications of these challenges.
The Role of Field Sobriety Tests in DUI Cases 
When someone is suspected of driving under the influence in Colorado, officers will often perform field sobriety tests as part of their investigation. These tests are designed to assess a person’s physical and cognitive coordination. There are three primary tests typically used by law enforcement officers:
- Horizontal Gaze Nystagmus (HGN): In this test, officers observe the movements of the driver’s eyes while asking them to follow a stimulus with their eyes. The test aims to identify any jerking or abnormal movements, which may indicate intoxication.
- Walk-and-Turn Test: The driver is instructed to take nine steps along a straight line, turn around, and return in the same manner. This test evaluates balance, coordination, and the ability to follow instructions.
- One-Leg Stand Test: The driver is asked to stand on one leg for 30 seconds without swaying or putting their foot down. This test gauges balance and mental focus.
For these tests to provide accurate results, the driver must be able to perform the physical tasks and maintain their coordination. However, as anyone who has spent a winter in Colorado knows, these conditions can sometimes make simple movements far more challenging.
Just like anything else, practice leads to proficiency. With over 35 years of combined experience, we've gathered extensive knowledge inside and outside the courtroom.
How Winter Weather Affects Field Sobriety Tests
Colorado’s winter months present several weather-related challenges that can impact an individual’s ability to successfully complete field sobriety tests. Icy roads, snowstorms, and freezing temperatures are just a few of the conditions that can interfere with test performance.
Slippery Surfaces and Poor Traction
Snow and ice are common in Colorado’s winter weather, which can make walking a serious challenge. The walk-and-turn test relies on the ability to walk heel-to-toe along a straight line, but this is nearly impossible on icy or snow-covered surfaces. Even drivers who are not under the influence may struggle to stay steady, risking failure due to environmental conditions, not impairment.
The one-leg stand test is another area where slippery conditions play a major role. The task requires balancing on one leg, which is significantly more difficult on uneven or icy ground. A driver might be completely sober but unable to stand still without wobbling or putting their foot down due to the unstable footing caused by the weather.
Bulky Clothing and Limited Mobility
Colorado residents are accustomed to bundling up during the colder months. However, layers of winter clothing, such as jackets, scarves, and boots, can make it harder for individuals to perform field sobriety tests that require free movement. Boots, in particular, can restrict the ability to walk heel-to-toe, further complicating the walk-and-turn test. The bulkiness of outerwear may also hinder the smooth execution of the one-leg stand test. The inability to move freely due to heavy winter clothing could lead to poor performance, even in those who are not impaired.
Discomfort and Impaired Focus
Even if the weather isn’t actively hindering the physical tasks required for field sobriety tests, the cold itself can cause discomfort that distracts a driver from performing the tests to the best of their ability. Cold temperatures can lead to stiff joints and numbing fingers, which impair coordination and focus. In extreme cases, numbness or shivering could result in shaking or unsteady movements during the test, causing a false positive result on the officer’s part.

Reduced Visibility and Poor Lighting Conditions
The winter months in Colorado are often characterized by reduced daylight hours and poor visibility due to snow or fog. Officers administering the horizontal gaze nystagmus test rely on being able to clearly observe the movements of a suspect’s eyes. Snow, fog, or dim lighting conditions may hinder their ability to accurately assess a driver’s eye movements. Even a slight difficulty in seeing the subject’s eye movement could lead to inaccurate conclusions about their level of impairment.
Legal Implications: How Weather Can Affect the Outcome of Your DUI Case
In DUI cases, it’s critical to assess all aspects of the field sobriety tests to determine whether they were administered properly and fairly. The winter weather in Colorado can significantly influence the results of these tests, and defense attorneys often argue that weather-related factors may lead to inaccurate conclusions about a driver’s impairment.
For instance, if an officer fails to consider how snow or ice may have affected a driver’s ability to walk a straight line during the walk-and-turn test, the results may be unfairly skewed. A driver who is simply struggling with poor weather conditions may be mistaken for someone who is impaired, leading to a potential wrongful DUI charge.
In some cases, defense attorneys may use weather conditions as part of their argument to challenge the accuracy of the field sobriety tests. If you were arrested for DUI in winter weather, it’s important to have a skilled attorney who understands how these environmental factors can influence the results of the tests.
