March in New York brings unpredictable weather, with slushy roads and melting snow causing a hazardous mix for drivers. These conditions create additional challenges during DWI (driving while intoxicated) investigations. For drivers pulled over during this time, conditions such as slippery roads and wet surfaces can have a significant impact on the accuracy of roadside tests and the potential for false arrests. Arthur Pressman, Attorney at Law, understands how weather factors can affect DWI cases and offers valuable insights into how these weather conditions can complicate a defense.
Understanding how March’s unique weather conditions play a role in these investigations can mean the difference between a successful defense and a wrongful conviction. Law enforcement must take extra care when conducting sobriety tests under these circumstances, and drivers need to be aware of their rights during such encounters. In this article, we will dive deep into how slushy roads and melting snow impact DWI investigations, how it affects the evidence collected, and how these challenges may be used to defend against a DWI charge.
The Impact of Weather on DWI Investigations 
Driving while intoxicated (DWI) charges in New York can carry serious consequences, including heavy fines, suspension of driving privileges, and even jail time. However, weather conditions in March often lead to inaccurate determinations of impairment, which can result in unfair charges. For instance, slushy and wet roads may cause a driver to exhibit behavior that could be misinterpreted as intoxication.
- Erratic Driving Behaviors: Slushy roads create instability, and drivers may swerve or struggle to maintain a steady course. Police officers may mistakenly interpret these actions as signs of drunken driving, when in reality, they are simply the result of weather-related difficulties.
- Field Sobriety Tests on Slippery Roads: During a DWI stop, field sobriety tests are often used to assess a driver’s level of impairment. Tests such as the walk-and-turn or one-leg stand are designed to be performed on dry, even surfaces. When conducted on slushy, slippery, or uneven roads, these tests are inherently difficult, even for sober individuals. This makes it much easier for law enforcement officers to incorrectly accuse a driver of being impaired.
- Breathalyzer Testing and Melting Snow: Breathalyzer tests are another tool used by law enforcement to determine blood alcohol content (BAC). However, the accuracy of these tests can be influenced by a number of factors, including residual alcohol in a driver’s mouth, which can be exacerbated by the cold, wet conditions that often accompany slushy roads. Additionally, melting snow may cause discomfort or distraction, leading a person to give less-than-ideal responses during the test.
I was advised by a mutual acquaintance to contact Mr. Pressman following my DWI that I received on December 28, 2015. This was the best advice that I could have been given. He was available immediately to speak with. I was put at ease after speaking with him. It was my first DWI and I had no idea what to expect. It was an isolated case of making a very foolish decision to drive. I had so much anxiety and fear of the unknown. Throughout my whole case Mr. Pressman was very reassuring and kept a positive attitude about what my outcome was going to be. He was available several times when I had random questions and never made me feel like an inconvenience. He was right! My case ended up being reduced to a violation from a misdemeanor and now I can finally begin to have my life back to normal. It was a hard lesson to learn but with the right attorney by your side the transition will be easier. Anita D.![]()
How Slushy Roads and Melting Snow Affect DWI Stops
In addition to the direct impact on field sobriety tests, the weather also complicates the process of making a DWI stop and gathering evidence. Police officers need to make decisions quickly during a stop, and bad weather can lead to misjudgments or even wrongful arrests.
- The Effect of Snow and Slush on Officer Discretion: Officers are trained to recognize certain signs of intoxication, such as erratic driving, slurred speech, or unsteady movements. However, bad weather conditions—particularly slush and melting snow—can cause drivers to display behaviors that might look similar to the signs of impairment. For example, a driver struggling to maintain control over their vehicle due to slippery roads might be mistaken for someone who is intoxicated.
- The Risk of Overreaction by Law Enforcement: In weather-related DWI stops, officers may jump to conclusions too quickly, especially if they believe the driver is not maintaining proper control of their vehicle. For instance, an officer might pull over a driver for swerving or driving too slowly and assume that they are intoxicated, overlooking the weather conditions that contributed to the erratic driving.
- Increased Risk of False Positives: Slippery conditions can result in false positives during sobriety tests. For example, when asked to perform a one-leg stand, the driver might struggle to maintain their balance due to the icy or slushy surface. While this could be interpreted as a sign of impairment, it’s just as likely that the unstable surface is the true cause.

The Science Behind Slippery Roads and Impairment
Research shows that slippery surfaces, including wet and slushy roads, significantly affect a driver’s ability to maintain control of a vehicle. When roads are covered in slush or ice, it becomes harder for a driver to steer and stop smoothly, leading to abrupt movements. This can easily be misinterpreted by law enforcement officers as signs of intoxication. Understanding this scientific reality can play a key role in defending against DWI charges.
- Loss of Vehicle Control on Slippery Roads: Slippery or slushy surfaces make it difficult for vehicles to stop or navigate turns smoothly. A vehicle that fishtails or skids may appear as if the driver is under the influence, though they are simply responding to road conditions.
- Erroneous Conclusion Based on Driving Behavior: Since driving under the influence is typically associated with erratic or unsafe driving behavior, police officers are trained to look for signs such as weaving, speeding, or failing to maintain lane position. However, these behaviors can often be attributed to weather-related challenges, especially during the winter-to-spring transition.
- The Impact of Temperature and Snow Melting: Melting snow also creates dangerous conditions that affect a driver’s ability to respond quickly to changing traffic situations. Slushy puddles and changing road conditions can cause abrupt stops or movements that resemble intoxication, but they are due to factors beyond the driver’s control.

How Weather Conditions Affect the Breathalyzer Test
Breathalyzer tests are a primary tool used to determine a driver’s BAC. However, the accuracy of these tests can be compromised in certain weather conditions. During March in New York, when snow is melting and the roads are wet, the conditions inside the driver’s mouth can significantly alter the test results.
- Residual Alcohol and Breathalyzer Accuracy: When drivers are stopped for a suspected DWI, they are typically asked to submit to a breathalyzer test. However, slushy roads and melting snow can cause drivers to consume drinks that may leave alcohol residue in their mouth, which can interfere with the breathalyzer’s results. This is especially problematic when the residue is a non-intoxicating amount of alcohol that the breathalyzer detects as though it’s affecting the driver’s BAC.
- Discomfort from Wet Conditions: As drivers deal with wet conditions during a DWI stop, they may be shivering or uncomfortable. This discomfort can lead to them performing less effectively on the breathalyzer, further complicating the results and making the test harder to trust.
DWI Defense and Weather-Related Challenges
In defending against a DWI charge during March, experienced attorneys like Arthur Pressman, Attorney at Law, can use weather-related challenges to build a strong case. Attorneys can argue that the poor road conditions and cold temperatures played a role in the alleged erratic driving or failures to perform field sobriety tests accurately.
- Expert Witness Testimony: Expert witnesses in traffic safety and weather conditions can help provide insight into how slushy roads or melting snow affect driving behavior. This expert testimony can challenge the officer’s assumptions about impairment and cast doubt on the evidence gathered during the stop.
- Challenging the Breathalyzer Results: Defense attorneys may also challenge the results of breathalyzer tests, arguing that weather conditions like residual alcohol in the mouth caused inaccurate readings. These challenges can undermine the prosecution’s case and result in reduced charges or dismissal.
Slushy roads and melting snow in New York during March can have a profound effect on DWI investigations. These weather conditions complicate both the accuracy of field sobriety tests and breathalyzer results, leading to the potential for false arrests. If you have been charged with DWI during the winter-to-spring transition, it’s essential to work with an experienced attorney like Arthur Pressman, Attorney at Law, who can assess the circumstances of your case and help you mount a defense based on the weather-related challenges of the time.
