2021 annual vehicle inspection requirements for tires are: tires must not be excessively worn; tire tread patterns must be consistent; all four tires should have matching tread patterns, or at least the front two or rear two should match, but left and right tread patterns must not differ. The functions of tires are: to transmit driving force, braking force, and steering force for vehicle operation; to support vehicle loads; to reduce and absorb vibrations and impacts during driving. Tire maintenance methods include: regularly removing stones stuck in tire grooves; minimizing exposure to direct sunlight; promptly checking tire pressure; paying attention to suspension maintenance; regularly inspecting front wheel alignment; adopting careful driving habits by choosing smooth road surfaces and avoiding objects that could puncture or scratch tires, as well as chemical spills that may corrode tires.

What is the penalty for over-the-line parking?

Over-the-line parking is generally penalized with a 2-point deduction. When the entire vehicle crosses the parking line, meaning both the front and rear wheels have crossed the parking line but not the opposite stop line, it is considered over-the-line parking. If the vehicle crosses the stop line when the red light is on but stops immediately, the traffic police will penalize it as driving or parking against regulations, not as running a red light. To confirm that a driver has run a red light, at least three photos are required: one showing the vehicle pressing against the stop line while the light is red, another showing the vehicle past the stop line while the light is still red, and a third showing the vehicle passing through the intersection while the light remains red. According to the new traffic regulations, driving through an intersection without following the prescribed driving or parking rules will result in a 2-point penalty.

What is the Difference Between Full-Speed Adaptive Cruise Control and Adaptive Cruise Control?

Full-speed adaptive cruise control and adaptive cruise control differ as follows: Speed limitations vary: Full-speed adaptive cruise control can be used at any speed; adaptive cruise control can only be used above 40 km/h or 60 km/h. Nature differs: Full-speed adaptive cruise control does not require the driver to touch the accelerator or brake pedal during vehicle operation; adaptive cruise control assists the driver in driving and reduces fatigue. Adaptive cruise control technology is based on active safety configurations and requires radar, ultrasonic, and infrared sensors to detect obstacles, pedestrians, and vehicles ahead. It must have automatic braking functionality to ensure precise distance control.

How Many Days Are Free on the Highway?

Highway toll-free periods are applicable during four national statutory holidays: the Spring Festival, Qingming Festival, Labor Day, and National Day. The toll-free period starts at 00:00 on the first day of the holiday and ends at 24:00 on the last day of the holiday. For ordinary roads, the toll-free status is determined by the time when the vehicle passes through the toll lane of the toll station, while for highways, it is determined by the time when the vehicle exits the toll lane at the highway exit. Waiving tolls for small passenger vehicles with seven seats or fewer during major holidays is an important measure to adjust and improve the toll road policy. It plays a significant role in enhancing road capacity and service levels during major holidays and reducing the public's holiday travel costs.

What are the signs that brake fluid needs to be replaced?

The signs that brake fluid needs to be replaced are: 1. During emergency braking or continuous braking, the brake warning light intermittently flashes, which is due to the reduction of brake fluid. It should be inspected and replaced in time, otherwise it will affect the braking effect; 2. When the car is driving normally at a speed of more than 40KM/h and the brakes are applied sharply, the braking distance becomes longer. Excluding the factors of the brake pads, it is the problem of the brake fluid; 3. Deteriorated brake fluid will make the brake pedal feel soft even when it is pressed to the bottom, especially after continuous and frequent braking. The feeling of pressing the brake pedal will be much softer than before and elastic. After a certain period of use, the boiling point of the brake fluid will decrease, and it will be contaminated and oxidized to varying degrees. The heat resistance point of the brake fluid decreases with the change of the quality of the oil, gradually decreasing from 464°F (240°C) to 320°F (160°C). If it falls below the safety lower limit, it will endanger the brake system and cannot be ignored. Under normal driving conditions, the brake fluid will absorb about 3% of water in 2 years, reaching the critical point of failure.

How to Remove Odors and Formaldehyde from a New Car?

Methods to remove odors and formaldehyde from a new car: 1. Use bamboo charcoal bags, which have strong odor-absorbing capabilities. They can effectively and directly eliminate odors inside the car, with long-lasting effects and quick results. 2. Car owners, especially those with new cars, should develop the habit of opening doors and windows before driving to allow circulating air to dilute and disperse toxic gases inside the vehicle. It's also advisable to keep windows open as much as possible while driving. 3. Fruit peels can also help with odor removal, such as those from pomelos and lemons. Pomelos function similarly to bamboo charcoal bags, both having odor-absorbing properties. Lemons, on the other hand, are effective due to their fresh and long-lasting fragrance, delivering excellent results.

What does the yellow exclamation mark on the car mean?

The appearance of an exclamation mark on the car dashboard indicates an abnormality or malfunction in the corresponding system. There are many indicator lights on the car dashboard with exclamation marks, such as the tire pressure indicator, lighting fault indicator, steering system fault indicator, brake system fault light, transmission fault indicator, and wiper fault indicator. Below is a detailed introduction to the exclamation mark warning lights: General faults: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a fault in the car's general performance, components, or functions. Main issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. It is necessary to go to a 4S shop for inspection to identify the source of the fault. Automatic transmission fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating a malfunction in the transmission or transmission lubricant level below the normal range. The transmission oil should be replaced promptly. Brake system fault: A circle with parentheses and an exclamation mark in the middle. This represents a brake system warning, mainly indicating a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Abnormal tire pressure: A horizontal line with parentheses and an exclamation mark below. This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator, indicating a fault in the car lights. Solution: Go to a 4S shop for inspection as soon as possible, or check by yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights, to identify the problem. In addition, during daily use of the vehicle, the warning lights displayed on the dashboard are divided into two different colors: yellow and red: Yellow indicates a fault in the corresponding system, but the problem is not very serious. Reduce speed and proceed to the corresponding repair point for maintenance to eliminate potential hazards in time. Red indicates a very serious problem in the corresponding system. In this case, do not continue driving. Pull over immediately and call for professional help to prevent unpredictable dangers to the vehicle and personal safety caused by forced driving. It should be noted that when the car is started, all lights will turn on, and the system will perform an automatic check. After the check is completed, the lights will turn off automatically. If a light does not turn on when the ignition is turned on, stays on without turning off, or lights up while driving, it indicates a fault in the related system. In such cases, seek professional help promptly for car inspection to eliminate potential hazards.
