How to Deal with Branch Scratches on Car Paint?

If it's just a very shallow scratch on the surface paint, you can use a compound to treat it. The wiping method involves straight-line wiping. Once the scratch disappears, use a finer compound to wipe and then apply wax. If the rust is not severe, first use very fine water sandpaper dipped in water to sand the rust spots in a straight line in the same direction—remember not to sand in random directions. After completely cleaning, apply a layer of primer. For new scratches, clean them and apply primer directly. Once the paint is dry, use water sandpaper to smooth it, then apply the original factory paint over the primer or use a touch-up pen for coloring. For new small scratches, you can gently apply toothpaste in a circular motion on the scratch. However, after rain or washing the car, you need to reapply it. Toothpaste can provide temporary rust prevention, but during the next full car maintenance, it's best to properly repair the scratch. If the scratch cannot be wiped off, it is recommended to seek professional help for an effective exterior paint refurbishment, which helps extend its quality and effect. If minor scratches on the car paint are left untreated, they can easily lead to rust on the car's paint surface, which is detrimental to future maintenance.

Does Crossing the Line on Yellow Light Count as Running a Red Light?

According to the "Regulations for the Implementation of the Road Traffic Safety Law": When the yellow light is flashing at an intersection, vehicles that have already crossed the stop line can continue to pass and will not be considered as running a red light; if the yellow light is already on and the vehicle continues to rush through, being caught on camera in this situation will count as running a red light. The criteria for determining running a red light: Electronic eyes capture three photos as evidence for running a red light: the front wheels crossing the stop line, the rear wheels crossing the stop line, and the front wheels crossing the opposite stop line. Only when all three photos are present will it be considered as running a red light. To avoid running a red light, pay attention to the following points: When there is an arrow signal light, watch the arrow light; otherwise, watch the round light; When the red light is on, the front of the vehicle must not cross the stop line; When the yellow light is on, the front of the vehicle must not cross the stop line; When the green light just flashes, if the distance is close and the speed is fast, you should pass, as braking might not stop the vehicle in time and it could cross the stop line; if the distance is far or the speed is slow or the intersection is congested, you should stop; When driving in the city, develop the habit of looking for traffic lights whenever you see a crosswalk or stop line at an intersection, ensuring traffic lights are within your field of vision. Violating traffic signal rules results in a 6-point deduction and a fine. Article 90 of the "Road Traffic Safety Law of the People's Republic of China" stipulates: Motor vehicle drivers who violate road traffic safety laws and regulations regarding road passage shall be given a warning or fined not less than 20 yuan but not more than 200 yuan. If this law provides otherwise, penalties shall be imposed accordingly.

How long should you practice Subject 3 before taking the test?

Generally, practicing Subject 3 for about 3-7 days is sufficient before taking the test. Although Subject 3 involves many test items, they are all basic operations such as turning, making U-turns, and shifting gears. These fundamental skills have already been introduced during Subject 2 training, so you have a foundation—you just lack some road experience when driving in real traffic. The exact duration of practice required depends on individual learning efficiency. In most regions, Subject 3 practice begins only after successfully scheduling the test. For test scheduling, the earliest you can secure a slot is about 10 days before the exam. This means that in most areas, after scheduling Subject 3, you only have around 10 days to prepare, including arranging a coach and waiting for practice time, leaving about a week for actual practice. Additionally, in some high-demand areas, coaches may only schedule practice sessions three days before the test. Key Points for Subject 3 Gear Shifting: When shifting gears, avoid looking down at the gear lever. If you shift into the wrong gear, you can return to the original gear and try again. Speed: On roads without specific gear-shifting requirements, it is best to drive at 25 km/h in 2nd gear. Lights: Pay attention to the timing when using turn signals—activating them too early, too late, or for too short a duration can affect your test score. When using turn signals, it's best to hold the lever to prevent it from automatically turning off as the steering wheel returns to the center position.

Do Cars Need to Wear Masks?

1. Is it necessary for cars to wear masks? Whether a car needs to wear a mask doesn't depend on whether others are doing it, but on whether your car actually needs it. If your beloved car is parked for long periods in areas with a lot of flying debris like willow catkins, wearing this 'mask' is highly necessary. Whether you drive or not, willow catkins will find their way into the car's air intake grille. Additionally, if the roads you frequently drive on are indeed often filled with flying debris like willow catkins, then your car must wear a mask. The reasons will be explained later. If your city has excellent environmental management with minimal flying debris like willow catkins, and you mainly drive within the city, you can skip this odd accessory. Radiator Blockage 2. Why should cars wear masks? As we all know, the car's engine radiator and air conditioning radiator are located behind the grille, made from very delicate cooling materials. Countless cooling holes are distributed across the radiator, allowing it to function efficiently when cooling or heat exchange is needed. However, if these holes get clogged with willow catkins or other debris, the radiator's efficiency will drop sharply, potentially leading to overheating and engine damage under extreme conditions. If the air conditioning radiator's holes are blocked, the cooling effect will be significantly reduced or even fail. Rather than facing expensive repairs, it's much better to maintain your car properly. Some might say, 'If the radiator is clogged, just use a water jet to clean it!' Never do this! The reason for using a car 'mask' is also because the radiator is very fragile and cannot withstand the force of a regular water jet. The pressure can bend the radiator fins, causing a more severe and harder-to-repair blockage. Do you really want to replace the radiator? 3. How to properly maintain the radiator? Actually, besides using a car 'mask,' there are many other ways to maintain the radiator. The most common method is installing an insect screen, which is easily available online. Vehicle-specific screens work best and are simple to install. The basic idea is to place a mesh grille in front of the radiator, which is both easy to install and clean—a long-term solution. The reason I don't recommend this 'mask' is that it's neither aesthetically pleasing nor durable, often falling apart after a few uses and failing to protect the radiator. Worse, if it accidentally covers the license plate, you might get fined by traffic authorities. If you don't have a car 'mask' or an insect screen, take a moment to bend down and inspect the radiator through the grille. The condition of the fins might shock you. Yesterday, due to hot weather, I turned on the AC and noticed poor cooling. Upon checking, I found the radiator covered in willow catkins and dead insects, prompting a thorough cleaning today. 4. How to clean the radiator? There are two methods: an amateur approach you can do yourself and a professional method requiring a repair shop. First, the amateur method. This works for cars where you can directly touch the radiator. Start by lightly wetting the radiator with water—avoid high pressure to prevent damaging the delicate fins. Then, use a soft brush to gently remove surface debris. The professional method involves removing the radiator and treating it with specialized cleaning agents until it's restored to its original condition.
