Solutions for fog inside the car are as follows: 1. Turn on the air conditioning: After the engine warms up, turn on the cold air blower, temporarily close other air ducts, and concentrate the airflow directly on the glass surface to quickly disperse the fog. 2. Open windows for ventilation: You can use the warm or cold air from the air conditioning to solve the problem. The car's air conditioning system has a defogging function for the windshield. 3. Use some defogging products: Before driving, you can spray a little on the windshield, rear window, four side windows, and the exterior rearview mirrors. This defogging spray forms a film on the glass surface, making it harder for fog to form.

I've been driving for many years, and the fog inside the car in winter is always troublesome, mainly caused by large temperature differences and high humidity. To deal with it, first locate the air conditioning control panel, press the defrost button to let the fan blow air onto the windshield; turn up the temperature, around 26 degrees, and switch to the external circulation mode, so the warm air can quickly evaporate the water droplets. Avoid wiping the glass directly with a cloth, as it may leave oil stains and make it blurrier. If the fog is severe, pull over immediately, open both side windows to let in some air before driving off. During regular maintenance, remember to clean the inside of the glass to reduce dust buildup. There are also some anti-fog sprays that work well—applying a layer can prevent fogging for several days. In short, stay calm, prioritize safety, and ensure clear visibility before hitting the road.

Is it necessary to display the annual vehicle inspection sticker?

It is mandatory to display the annual vehicle inspection sticker on your vehicle. Failure to do so may result in random checks, fines, or even vehicle impoundment. The environmental protection label has now been abolished, as it has been merged with the annual inspection label. Not displaying the inspection sticker is considered a traffic violation, so it must be affixed. Additional Information: Vehicle Annual Inspection: This refers to a mandatory inspection for all vehicles that have obtained official license plates and registration certificates. It is equivalent to an annual physical examination for the vehicle according to the "Technical Conditions for Motor Vehicle Operation Safety." The vehicle annual inspection helps promptly eliminate potential safety hazards, encourages better vehicle maintenance, and reduces the occurrence of traffic accidents. Below are the specific requirements: 1. The upper right corner of the vehicle's front windshield must display not only the annual inspection pass label but also the environmental protection label and insurance label; 2. According to the "Road Traffic Safety Law," all vehicles on the road must display the current year's inspection label in a visible position on the upper right corner of the front window. Vehicles that fail to properly display the annual inspection pass label will be penalized with 1 demerit point and a fine of 50 yuan.

What Are the Precautions for Safe Driving in Snow and Ice Weather?

Precautions for safe driving in snow and ice weather are as follows: 1: Pay attention to tire pressure: Release some air from the tires to increase the contact area between the car and the icy road surface, which can enhance tire grip. 2. Slowly release the clutch: Always lift the clutch slowly and accelerate gently on icy roads. If you press the accelerator pedal too hard, it may cause side skidding or wheel spin, and even lead to loss of vehicle control. 3. Maintain a safe distance: Remember to keep a safe following distance, at least three times the normal distance, and drive at the lowest possible speed. 4. Avoid driving near the roadside: Try to drive in the tracks left by the vehicle ahead and avoid driving near the roadside. If you feel the drive wheels slipping, immediately ease off the accelerator. 5. Use lights properly: In snowy and icy weather with low visibility, be sure to turn on the width lights, fog lights, low beams, hazard warning lights, etc., and honk the horn as needed to indicate the distance between vehicles.

What to Do When All 12 Points on Your Driving License Are Deducted

If a motor vehicle driver accumulates 12 penalty points within one scoring cycle, the traffic management department of the public security authority shall detain their motor vehicle driving license. Below is some relevant information from traffic laws regarding driving license point deductions: 1. Handling of two 6-point violations: You can first address one 6-point violation record, as general violations are registered on the motor vehicle rather than the driver's license. Therefore, you can initially handle one 6-point violation. However, if both violations are on-the-spot tickets issued by traffic police, the driving license is usually already detained, and you will need to attend full-point education at the traffic police department. 2. Handling when 12 points are insufficient: According to relevant regulations, if a driving license accumulates 12 points within one scoring cycle, the driver must report to the traffic police department or the license issuing authority within 15 days to undergo a 7-day study on road traffic safety laws, regulations, and related knowledge. After completing the study, the driver must retake the theoretical test (Subject One). Only upon passing the test will the points be cleared, and the driving license returned.

What to Do When the Car Gets Foggy on Rainy Days?

Here are some methods to deal with foggy windows on rainy days: 1. Prepare an anti-fog spray in advance: Anti-fog spray is a common tool for preventing window fogging and can be purchased through various channels. When using it, simply spray it on the glass surface and wipe it evenly. 2. Use the air conditioner to remove fog: If the windows have already fogged up, you can turn on the air conditioning to quickly balance the temperature inside and outside the car, achieving a defogging effect. 3. Use the one-touch defogging button in the car: Nowadays, many cars come with a defogging button to handle window fogging on rainy days. You can look for this button on the car's control panel. The icons are usually divided into front and rear window defogging. 4. Use tissues or a cloth to wipe the glass surface: On rainy days, fog usually forms on the inner surface of the windows. You can prepare tissues or a cloth in the car to wipe the glass when fog appears. This method provides immediate defogging but does not offer a long-lasting solution.
