Reasons for interior glass frosting: Interior glass frosting is a phenomenon of water vapor condensation caused by the temperature difference between the inside and outside of the vehicle. When the interior temperature gradually drops to match the outside temperature, the water vapor on the glass freezes. Below is relevant information: 1. De-icing spray: De-icing spray can be used to remove frost. Special de-icing sprays can melt the ice on the windshield without causing scratches. 2. Precautions: Do not use the windshield wipers or hard cards to scrape off the ice on the windshield, as this may damage the wiper motor or scratch the glass. Instead, use a hot towel rather than pouring hot water directly to melt the ice, then wipe it clean with a dry towel.

Can China III Motorcycles Still Be Registered?

China III motorcycles can no longer be registered now, as they have been ineligible for registration since July 2019. After July 2019, only China IV motorcycles that meet the standards can be registered, because the exhaust emission standards of China III motorcycles did not meet the requirements, leading to their discontinuation in production and sales. Documents required for motorcycle registration: The original invoice of the motorcycle to be registered, the owner's ID card, and the original certificate of conformity of the motorcycle. Additionally, the original compulsory traffic insurance policy for the motorcycle and the proof of payment for the purchase tax are required. Procedures for motorcycle registration: First, the certificate of conformity of the motorcycle needs to be inspected and stamped by the traffic police department. Then, with the invoice, ID card, and other documents, the purchase tax should be paid at the tax bureau. After completion, the motorcycle will be photographed and the registration procedures will be handled at the traffic police department.

Below what tire pressure should you no longer drive?

Tire pressure below 1.7bar is unsafe for driving. Vehicles are typically equipped with a tire pressure monitoring system, which usually triggers an alarm when the tire pressure falls below 1.8bar. Therefore, this value is also applicable to tires without tire pressure monitoring sensors, and it is recommended not to go below this threshold. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes heavy steering and tendencies to veer, compromising driving safety; Increases movement in various parts of the tire, causing abnormal heating due to excessive rolling; Degrades the function of the cord and rubber, leading to delamination or cord breakage, and excessive friction with the rim causing damage to the bead area and abnormal wear; Multiplies the friction between the tire and the ground, sharply raising the tire temperature, softening the tire, and drastically reducing its strength. High-speed driving under these conditions may lead to a blowout; Increases tire body deformation, making the tire side prone to cracks, and generates flexing movements, leading to excessive heat, accelerating rubber aging, fatigue in the cord layer, cord breakage, and increases the tire's contact area with the ground, hastening shoulder wear.

How to Activate the Windshield Washer?

The windshield washer is activated by pulling the wiper control lever (located on the right side of the steering wheel) towards the driver. Below are the steps for replacing wiper blades: 1. Remove the wiper arm by lifting it to locate the release tab, press the tab and slide the wiper blade off parallel to the inner direction. 2. Replace the wiper blade by pulling the old blade out from one end, remove the metal strips inside the blade, identify the arrow direction marked inside the wiper arm, and insert the new blade accordingly. 3. After replacing the metal strips, insert the new wiper blade following the arrow direction. 4. Reinstall the wiper arm by sliding it back in parallel.

How many points does a newly obtained driver's license have?

A newly obtained driver's license has 12 points. Depending on the severity of the violation, points can be deducted by 12, 6, 3, 2, or 1 points at a time. Points deduction during the probationary period: In the first year, up to 11 points can be deducted, but exceeding 6 points will extend the probationary period by one year. If more than 6 points are deducted in the second year, the driver must undergo retraining. If 12 points are deducted during the probationary period, the license will be revoked. After the probationary period, deducting 12 points only requires attending training and passing an exam. Points deduction considerations during the probationary period: The points deduction depends on the driver's violations. The accumulated points in a single scoring cycle (one year) must not reach 12 points. If a driver's violation points reach 12 in a scoring cycle, they must attend training and pass the subject one exam (if the points reach 12 more than once, subject three will also be required) to clear the points. If the violation points do not reach 12 in a scoring cycle, the points will automatically reset to zero at the start of the next scoring cycle by the vehicle management system.
