You can make a U-turn on a single dashed line if there is no 'No U-turn' sign and it does not affect the normal flow of traffic. However, making a U-turn on a single solid line is not allowed and constitutes a traffic violation. According to the 'Road Traffic Safety Law,' violators will be fined 200 yuan and receive 3 penalty points. On long roads, there are usually white or yellow solid or dashed lines in the middle section or before intersections. U-turns are prohibited on any solid line. Cases where U-turns are allowed: Intersections with U-turn signs allow U-turns: If there is a clear U-turn sign at an intersection, you can make a U-turn. If there is a U-turn traffic light, follow its instructions. If there is no traffic light, make a U-turn only if it does not interfere with other vehicles or pedestrians. Intersections without explicit 'No U-turn' or 'No Left Turn' signs allow U-turns: If there is no explicit prohibition, you can make a U-turn. 'No explicit prohibition' means the intersection has no 'No U-turn' or 'No Left Turn' signs and no solid lines in the center. In such cases, you can safely make a U-turn. Yellow grid lines also allow U-turns: Yellow grid lines are no-parking zones marked at intersections prone to congestion due to temporary stops, important entrances, or other designated areas. Parking (including waiting at traffic lights) on these lines is a violation. Although stopping is prohibited, U-turns are allowed on yellow grid lines unless there is a central barrier. Yellow grid lines without barriers are equivalent to 'U-turn permitted.' Intersections with U-turn traffic lights: This is straightforward—if there is a U-turn light, you can only make a U-turn when it is green. When 'No Left Turn' and 'U-turn Permitted' signs coexist: U-turns are allowed, but left turns are prohibited. Note that 'No U-turn' is not the same as 'No Left Turn.' Things to note when making a U-turn at an intersection: Check road markings—if they are solid lines, U-turns are prohibited under any circumstances. Continue driving to find a suitable spot. If there is a 'No Left Turn' sign, even without a 'No U-turn' sign, U-turns are not allowed at that intersection because U-turns inherently involve a left turn. U-turns must be made from the innermost left-turn lane. If you are in the second left-turn lane, you cannot make a U-turn at that intersection. Always yield to oncoming traffic when making a U-turn. If you interfere with straight-moving vehicles, you will bear full responsibility for any accidents. Near intersection stop lines, lanes often have guiding arrows. The leftmost lane may not always have a left-turn arrow—some have straight arrows. Even without explicit 'No U-turn' signs, U-turns are not allowed in such lanes. Making a U-turn on a crosswalk is also a traffic violation.

How to Deal with Foggy Car Windows While Driving?

Press the defogger button, turn on the air conditioning (A/C) switch, set the temperature to the lowest, and turn on the external circulation to defog. Foggy car windows can be cleared by using either cold or warm air, but warm air is slower than cold air. The most effective method is to use cold air, which blows dry cold air directly onto the glass, preventing water vapor from condensing on the glass and achieving the purpose of defogging. The method of using warm air to defog is the same as using cold air, but it should be noted that warm air should not be used for defogging on rainy days, as it will initially worsen the fog. When the car windows are foggy, external circulation should be turned on. The reason for foggy car windows: There is a certain temperature difference between the inside and outside of the car. If the temperatures inside and outside the car are different, the surface of the side with the lower temperature will have a lower saturated vapor pressure than the surrounding environment, causing water vapor to gather on the glass surface and form tiny droplets, resulting in fog. Methods to defog car windows: Air Conditioning Cooling: Use the air conditioning's cooling and dehumidifying function to reduce air humidity and remove fog. In summer, especially when many people enter the car and the air conditioning is not turned on in time, the humidity of the exhaled air is high, and the windshield will quickly fog up. At this time, you can turn on the air conditioning to blow cold air onto the windshield, using the air conditioning's dehumidifying function to quickly remove the fog on the windshield. However, if the humidity is too high and the air conditioning is not effective enough, you can slightly open the window to quickly reduce the humidity inside the car. Of course, it can also be used in combination with the air conditioning for faster results. Air Conditioning Warm Air: Use the method of reducing the temperature difference to remove fog. In winter, use warm air to blow hot air onto the glass, quickly raising the temperature of the front glass and reducing the temperature difference between the inner and outer surfaces of the window glass, which can promptly prevent excessive fogging on the windshield. However, it should be noted that the rear and side windows heat up slowly, so it takes longer to remove all the fog. Whether the air conditioning is automatic or manual, turning it on helps with dehumidification; the temperature control should not be set to the coldest position, otherwise, the outer surface of the windshield may fog up after prolonged use. Spraying Anti-Fog Agents for Prevention: Spray a small amount of defogging agent on the car windows and wipe it clean to remove dirt and stains from the glass. While cleaning the glass, a thin transparent protective film is formed on the glass, which effectively prevents water vapor from condensing on the glass and forming a fog layer, making it especially suitable for cold winters. Alternatives to anti-fog agents include dishwashing liquid, soapy water, glycerin, alcohol, or saline solution. After drying, use chamois or a soft dry cloth to wipe off any excess fibers, which can keep the car windows fog-free for several days. Opening Windows for Airflow: If the fog inside the car is not heavy, you can open the windows on both sides to create airflow between the inside and outside of the car, reducing the temperature difference and allowing the fog to slowly disappear. The principle of this method is the same as using cold air from the air conditioning. The downside of opening windows for airflow is very obvious: it cannot be used in rainy or snowy weather, on highways, or when the fog is heavy. Rear Window Heating: Most cars have a rear window electric heating function, although the button positions may vary, the function is the same. Turn on the rear window heating switch, and the fog on the rear window will disappear in about a minute.

How many spark plugs should be replaced at a time?

When replacing spark plugs in a car, it is generally recommended to replace all of them at once. Theoretically, even if you replace only one spark plug with the same brand and model, the discharge gap and resistance between the new and old spark plugs will differ. Not replacing all of them can lead to issues such as engine shaking, difficulty in acceleration, and increased fuel consumption. This is because differences in spark plugs can cause variations in ignition timing and energy, resulting in an imbalance in power among the four cylinders. Below are some tips to extend the lifespan of spark plugs: 1. Regularly drive the vehicle on highways. High-speed driving increases fuel injection, which helps clean carbon deposits in the engine cylinders and on the spark plug electrodes, restoring the spark plug's ignition efficiency and prolonging its lifespan. 2. Use high-octane gasoline periodically. High-octane gasoline has a higher octane rating and burns more completely, which also helps clean carbon deposits. It is not recommended for car owners to replace spark plugs themselves; it is best to have them replaced at a service station or repair shop.

How many kilometers should a new car drive before maintenance?

For new car maintenance, different manufacturers specify different maintenance intervals, generally every 3,000 or 5,000 kilometers. Below are the relevant details: 1. The first maintenance usually involves changing the engine oil and oil filter. It includes checking the engine's working condition, such as whether all pipe connections are normal, if there are any leakage points, whether the engine sounds normal, and if there are any abnormal noises. 2. Inspect the wear level of brake pads and tires, and after lifting the vehicle, check if there are any deformations or damages to the chassis caused by collisions. 3. The purpose of changing the engine oil is to ensure better lubrication for the engine. Since the lubricating effect of the oil deteriorates after some use, it needs to be replaced.

What Causes Loud Wiper Blade Friction Noise?

Loud wiper blade friction noise is generally caused by sand particles trapped in the grooves on both sides of the wiper rubber or due to aging and hardening of the wiper blade. Dirt and debris on the windshield can also create noise when the wiper moves. Regular cleaning of the windshield and replacing aged wiper blades can resolve the issue. More details are as follows: 1. Wiper blades, also known as windscreen wipers or windshield wipers, are devices used to remove rain and dust from a vehicle's windshield, improving driver visibility and enhancing road safety. 2. The wiper blade rubber should remain adequately moist. Only with sufficient moisture can it maintain excellent flexibility, ensuring tight contact with the windshield. Precautions for Wiper Blade Usage: 1. When using wipers to remove dust from the windshield on sunny days, always spray windshield washer fluid to avoid dry wiping. 2. For stubborn or hard debris on the windshield, clean it manually. These substances can easily damage the wiper blade, leading to ineffective wiping. In severe cases, the wiper motor may also be affected. 3. When lifting the wiper blade during car washing or routine cleaning, hold the "backbone" of the wiper blade and gently return it to its position. Avoid snapping it back abruptly. 4. In winter, use an ice scraper to remove ice from the windshield before using the wipers to prevent overburdening them.
