Is Installing a Rear Spoiler Illegal?

If a car is fitted with a rear spoiler without undergoing the modification registration at the vehicle management office, it is considered illegal. The following vehicle modifications are not considered illegal: 1. Rear Spoiler Modification: When modifying a rear spoiler, the owner must file a record with the vehicle management office in advance. After the modification is completed, the vehicle must be photographed again to update the photo on the vehicle registration certificate. 2. Vehicle Body Color: The body color can be changed, but within 10 days, the vehicle must be photographed again at the vehicle management office to apply for a modification registration. Certain color schemes used by law enforcement vehicles are not allowed to be changed. 3. Partial Painting: If the change in body color covers less than 30% of the vehicle, there is no need to update the vehicle registration certificate through the vehicle management office. Additionally, wheels can be modified, but the size must remain the same as the original vehicle. The color or appearance can be changed freely, and no special registration for modification is required.

As an experienced veteran driver, I've seen many friends try to install rear spoilers over the years. Honestly, this isn't absolutely illegal, but it depends on the specific situation and local regulations. In China, vehicle modifications must comply with national safety standards and be registered with the vehicle management office to be considered legal. Adding a small spoiler might not be a big issue, but if it's too large or affects the car's balance, you'll definitely get pulled over by traffic police and risk fines or even penalty points. I suggest checking local traffic authority guidelines on your phone or consulting a professional mechanic before making any changes. Also, consider high-speed safety—if the spoiler isn't sturdy, it could detach and cause an accident, which really isn't worth it. Modifications are for personalization, but don't forget the principle of safety first.

As a young car owner, I enjoy pursuing cool car modifications, like adding a spoiler to enhance the overall sporty feel of the vehicle, which also gives me a sense of pride when driving around. However, based on my experience, making random modifications can easily attract the attention of traffic police, especially in first-tier cities. I've heard from fellow car enthusiasts that if a spoiler modification isn't properly registered, it will definitely fail the annual inspection, requiring removal and reinstallation, which is a waste of money. While modifications can enhance driving pleasure, it's essential to choose standard parts from reputable manufacturers and avoid cheap knockoffs. Safety is also a consideration—poorly installed parts might cause the car to lose control during sharp turns or on windy days. I believe it's crucial to do thorough research before modifying, consulting modification guides and legal manuals to avoid fines and regrets later.

The reasons for car lights continuously flashing are: 1. The hazard light switch is turned on; 2. Partial circuit failure connected to the vehicle's computer, bulb or ignition coil failure, stabilizer malfunction; 3. Poor wiring contact causing a short circuit, resulting in continuous light flashing; 4. The vehicle computer activates the recognition system for the anti-theft chip; 5. Insufficient battery power alerts the owner through flashing lights when the battery is low; 6. Brake system failure causing the tail lights to flash continuously; 7. The steering wheel is locked when parked, and the car activates the anti-theft function.

What Causes Excessive Tire Pressure?

The reasons for excessive tire pressure are: 1. Over-inflation of tires leading to high pressure; 2. Hot weather causing gas expansion and increased pressure; 3. Prolonged driving generating friction heat, resulting in higher pressure; 4. Aging and wear of suspension components related to wheels causing misalignment, uneven wear, increased temperature, and higher tire pressure. Effects of excessive tire pressure: 1. Reduced tire friction and adhesion, affecting braking performance; 2. Steering wheel vibration and deviation, decreasing driving comfort; 3. Accelerated wear of central tread patterns, shortening tire lifespan; 4. Increased vehicle vibration, indirectly affecting other components' longevity; 5. Excessive stretching deformation of tire cords, reduced elasticity, and increased load during driving; 6. Decreased resistance to punctures.

What is the reason for jerky acceleration and inability to increase fuel during cold start?

The reasons for jerky acceleration and inability to increase fuel during cold start are: 1. Excessive carbon buildup on the throttle valve and air flow meter, which can cause jerky acceleration and inability to increase fuel when pressing the accelerator; 2. Too much carbon deposit in the combustion chamber of the cylinder. The combustion chamber has a certain adsorption effect on gasoline, and excessive carbon deposits prevent normal adsorption of gasoline, thus prolonging the ignition start time; 3. Lean mixture causing insufficient gas thrust on the piston after ignition, prolonging combustion time and leading to engine overheating; 4. Intermittent operation of the engine due to high and low voltage component and circuit faults in the ignition system, resulting in discontinuous high-voltage sparking and causing weak acceleration.
