Preparing your vehicle for winter can be a daunting task, especially since the season can be unpredictable. A dangerous hazard to be aware of during winter is black ice. This insidious layer of transparent ice can form quickly, making roads treacherous and accidents more likely.
We’re taking a look into the dangers of black ice, providing practical tips for safe winter driving, and exploring preventative measures taken by road maintenance crews to keep the roads safe.
What is Black Ice?
Black ice refers to a thin coating of glazed ice on a surface, usually roads and pavements. Contrary to its name, it is not black but rather transparent; however, due to the pavement below it, it often takes on a dark appearance. This deceptive appearance can make it difficult to detect, especially at night or in low-light conditions. One of the main reasons black ice forms is from melting snow on or beside the road, especially after a winter storm when temperatures rise above freezing during the day and then the temperature drops sharply in the afternoon or at night, and any remaining water freezes and creates black ice. Rain can also contribute to black ice formation, especially when it freezes upon contact with cold road surfaces.
Preparing Your Vehicle for Winter
Before the harsh winter weather arrives, take the time to prepare your vehicle. Ensure your tires have adequate tread depth and consider switching to winter tires for optimal traction and handling. You should also have your battery tested to ensure it can withstand cold temperatures, any worn-out windshield wiper blades should be replaced, and washerfluid should be topped up with a winter-grade option!
Before each drive, maintain proper tire pressure to improve fuel efficiency and handling. Drivers should also take the time to clear all windows, mirrors, and lights of snow and ice before getting behind the wheel to improve your visibility while on the road. These proactive steps can significantly improve your vehicle’s performance and safety in winter weather.
Stay Calm and in Control
If you find yourself driving on black ice, it's important to remain calm and avoid panic. Your instinct may be to slam on the brakes, but this can exacerbate the situation and lead to a loss of control. Instead, gently ease off the accelerator and steer in the direction you want the vehicle to go. Gradually apply the brakes, if necessary, to slow down. If your vehicle is equipped with anti-lock brakes (ABS), apply firm, steady pressure to the brake pedal. The ABS system will automatically modulate the brake pressure to prevent wheel lockup.
If your vehicle starts to slide, avoid panic and sudden movements. Resist the urge to slam on the brakes, as this can exacerbate the skid. Instead, gently steer in the direction you want to go. If your vehicle is equipped with anti-lock brakes (ABS), apply firm, steady pressure to the brake pedal. The ABS system will automatically modulate the brake pressure to prevent wheel lockup and maintain steering control. For vehicles without ABS, gently pump the brake pedal to slow down and regain control. Don’t use cruise control in winter conditions, as it can reduce your ability to react quickly to changing road conditions.
Prevention Efforts
Municipalities and highway maintenance officials play a vital role in monitoring for black ice and taking preventive measures. They may pre-treat roads with de-icing agents to prevent ice formation, especially on bridges and overpasses, which are prone to freezing. However, heavy rain or prolonged freezing temperatures can diminish the effectiveness of these treatments. Road temperature, precipitation levels, dew point, and air temperature are significant factors that officials consider when monitoring for black ice and implementing prevention measures.
Common Areas for Black Ice Formation
Black ice is most likely to form on bridge decks and is typically found during the coldest parts of the day, such as early mornings and late evenings. These elevated structures are often exposed to colder air temperatures, increasing the likelihood of ice formation. Even after road treatments, it's important to be cautious since the road takes longer to warm up after a cold weather event. This means that small icy patches can still be present, especially in shaded areas or on bridges, even when temperatures have risen. When planning your morning commute, give yourself extra time, don’t rush, and stick to main roads, as they are typically treated more frequently and have better visibility.
