What should be checked when picking up a new car?

When picking up a new car, the following items should be checked: 1. Check the production date: Verify whether there is a significant gap between the production date and the pickup date. A smaller gap means the car might have been moved less. While it's impossible to avoid the movement from production to sales, a small gap between the production and pickup dates reduces the likelihood of the dealer tampering with the mileage. 2. Check the tires for completeness: Tires are a relatively straightforward way to inspect the car. If a new car has been used excessively, the tires will show severe wear. The tire hairs won't be as intact as on a new car, and in severe cases, they might be completely worn away. There may also be signs of damage on the tire surface. 3. Check if the interior packaging is intact: To prevent dust or damage after leaving the factory, the interior is usually wrapped in plastic film. If the new car has been used excessively by the dealership, the plastic film might be damaged.

What causes a loud noise when driving over a pothole without slowing down?

Reasons for abnormal noise when driving over potholes: First, check the shock absorber for faults by inspecting whether it is leaking oil. Below is an introduction to abnormal noises in cars: Car half-shaft issues: Due to long-term torsional fatigue and impact forces, the car's half-shaft is prone to bending, twisting, breaking, or wear and skew of the spline teeth. This can cause the car to shake rhythmically when accelerating within a certain speed range, accompanied by noise. The shaking disappears or lessens when the accelerator is released. Engine belt looseness: A slipping belt will produce abnormal noise. Once the belt slips, it leads to friction and high temperatures, causing the belt to stretch further and slip more severely, creating a vicious cycle. In this case, it is necessary to adjust the belt at a repair shop.

How to Solve the Problem of Fogging on the Outside of Car Windshield in Summer?

Introduction to measures for solving the problem of fogging on the outside of car windshield in summer: 1. Open windows for convection: If the fog is not heavy, you can open a gap in the windows on both sides to allow air convection inside the car. When the temperature inside the car approaches the outside temperature, the fog will dissipate. However, this method is only suitable for low-speed driving conditions. 2. Reduce wind speed and turn on external circulation: Lower the air conditioning wind speed and turn on external circulation, then adjust the wind speed to the setting that blows entirely on the glass. After a while, the fog will disperse. This method has a slower defogging effect and is only suitable for situations with light fog. 3. Mix anti-fog agent: The ratio of detergent to water is about 1:10. Dip a cloth in the mixture and apply it to the glass. This not only provides long-lasting defogging but also costs less. If there is no detergent, you can also use windshield washer fluid to remove fog.

How many points deducted from the driver's license require attending a course?

After a driver's license accumulates 12 penalty points, the traffic police will notify the driver to attend a course. Below are the relevant details: 1. Driver's license penalty points: Penalty points on a driver's license are a form of punishment for traffic violations. Depending on the severity of the violation, points can range from a minimum of 1 to a maximum of 12 per violation. The penalty point cycle lasts for one inspection period. If a driver accumulates 12 points within one cycle, they lose their driving privileges and are typically required to undergo at least 7 days of traffic safety education. Only after passing the exam can their driving privileges be restored. 2. Passing the exam: The penalty points will be cleared, and the driver's license will be returned. If the exam is not passed, the driver must continue attending the course and retake the exam. If the driver refuses to attend the course or take the exam, the traffic management department of the public security authority will announce the suspension of their driver's license.

Is modifying the front grille illegal?

The latest "Motor Vehicle Inspection Work Regulations" implemented on September 1, 2019, stipulate that as long as the modified front grille meets certain requirements, it is legal and does not need to be registered. If the modified front grille does not meet the requirements, it is also considered illegal. Therefore, when modifying the front grille, it must be done according to the requirements. The following are the requirements for modifying the front grille: 1. The modified front grille must be a style already filed by the manufacturer. It is known that many cars can be equipped with optional appearance sport kits or some appearance parts when purchasing, and these appearance parts have already been filed by the manufacturer with the vehicle management office. Modifying the original appearance parts after purchasing the car is legal. 2. The modified front grille must not change the length and width of the vehicle. According to the latest "Motor Vehicle Inspection Work Regulations", the modification of the front grille has been included in the legal scope, but it should be noted that the modified front grille must not change the length and width of the vehicle.

What Causes an Electric Tricycle to Switch from Forward to Reverse?

It may be due to a damaged reverse switch on the handlebar, causing the vehicle to remain in reverse mode. Alternatively, the reverse signal wire might be damaged and short-circuited with the vehicle's ground wire, which can also cause the vehicle to automatically enter reverse mode. Here is some related information: Reverse Mirror Linkage Function: The reverse mirror linkage function (automatic downward tilt of the mirror when reversing) only applies to the passenger-side exterior mirror. When the gear shift lever is switched to R (Reverse) gear, this function automatically adjusts the passenger-side exterior mirror to a pre-stored position suitable for reversing. After exiting R gear, the exterior mirror automatically returns to its position before reversing. Important Notes: Additionally, it should be noted that only one reverse linkage position can be stored. If another reverse linkage position is stored using other buttons on the driver's seat, the previously stored reverse linkage position information will be overwritten.
