Should You Keep a Window Open in Winter While Driving?

When winter rolls around, the question of whether to keep a window open while driving becomes a common topic. Given modern advancements in car technology, the answer is generally no, but there are still some instances where it might be beneficial.

The Old Days: The Utility of Open Windows in the Winter

Back in the 1970s, keeping a window open during winter was a practical solution. As the car’s interior heated up, the moisture in the air could condense on the cold windows, causing a foggy view. Having an open window could alleviate this issue by allowing air to circulate and reducing moisture build-up.

The Modern Car Environment: A Must-Have Versus an Anachronism

Nowadays, with the advancements in car technology, things have changed. Modern cars come equipped with advanced heating and air conditioning systems that can effectively manage the air quality inside the vehicle. Heating works to dry out the air, and the air conditioning system can operate alongside the heater to ensure a comfortable and clear driving environment. Keeping a window open can actually counteract the efficiency of these systems, leading to unnecessary moisture buildup and fogged windows.

Current Driving Tips for Winter Months

Winter driving requires extra attention and preparation. Here are some essential tips to keep in mind:

Properly prepare your vehicle: Ensure you have enough winter clothing and boots that can help you survive uncomfortable weather conditions outside the car. Check that your windshield washer fluid is winter-grade to prevent freezing and potential blockages. Allow for adequate stopping distance: Snowy conditions can make it difficult to brake and maneuver, so make sure you have enough distance to make a stop or a turn safely. Stay alert and be cautious of drivers who might not be as prepared. Brake on tarmac: If possible, brake on paved surfaces to minimize the risk of slippage on icy or snowy roads. Close windows when driving at high speed: At highway speeds, the wind noise can be distracting and unpleasant. Closing the windows can enhance your driving experience and reduce the risk of an earache or clogged ear.

Conclusion

In conclusion, barring the occasional need to let some fresh air in during a stuffy or moist trip, there is generally no need to keep a window open in a modern car during winter driving. Advanced ventilation systems and heating/cooling capabilities handle the air quality much more effectively than an open window. However, it can be beneficial to leave a window open for a tiny bit when the engine is off for extended periods to prevent misting on the windshield. The best practice is to adapt to the conditions and your car's capabilities, ensuring a safe and comfortable journey.
