Penalty points and fines may be imposed. Here is the relevant information: Impact of opening windows on the highway: Opening windows at high speeds generates significant noise due to the accelerated airflow, resulting in loud disturbances. There are considerations when opening windows on highways—doing it properly can freshen the air inside the car, creating a comfortable driving environment. However, improper window usage not only increases fuel consumption but may also lead to severe accidents, such as rollovers. Precautions for opening windows: When driving on the highway, either keep the windows closed or open only one window. Avoid opening two windows on the same side simultaneously, as this allows strong airflow to rush directly into the car. Do not open all windows completely, as this disrupts the airflow inside the vehicle, potentially causing small items to tilt or even get damaged. Additionally, loosely installed buttons or controls inside the car may be blown off.

As an enthusiast studying traffic regulations, driving on the highway with windows open does not incur demerit points or fines. According to China's Traffic Safety Law, this behavior is not considered a violation. Penalties and demerit points are typically imposed for speeding, drunk driving, or littering. However, if opening windows leads to hazards, such as objects flying out and hitting vehicles behind, it may be deemed improper conduct and subject to fines. In terms of safety risks, high-speed airflow from open windows generates significant noise that can interfere with navigation and increases the risk of accidents, such as debris flying in and causing injuries. It is advisable to keep windows closed or use air conditioning during normal driving, only opening them slightly for ventilation at low speeds. During vehicle inspections, ensure that window functions are normal and not stuck, as this could hinder emergency responses. In summary, while legally permissible, safety should always come first.

As a veteran driver with 20 years of experience, I often roll down the windows for fresh air on the highway and have never been fined. Penalties and demerit points are for obvious violations like speeding, while opening windows is just a personal habit. When the wind is too strong, it does get noisy, so I usually crack the window slightly or use the AC for ventilation to balance it out. I recall one long trip where I drove with the windows down and ended up with dust all over the car, but no ticket. However, be careful not to do anything foolish like tossing cigarette butts out the window, as you might get caught on camera and fined. From a safety perspective, opening windows increases fuel consumption and wind resistance, which isn’t economical. I recommend that new drivers keep the windows closed to maintain a quiet and smooth ride.

As a frequent highway commuter, I've never heard of getting points deducted or fined for rolling down windows to save fuel instead of using AC. Regulations target serious violations like crossing lines. Window noise can sometimes interfere with music enjoyment, but I solve this with headphones. The risk lies in strong winds potentially scattering loose items that could harm others. My advice is to crack windows slightly for ventilation while prioritizing safe driving.
