Only legally modified cars can be driven on the road, while illegally modified cars are not allowed. Legally modified cars must apply for a change of registration at the vehicle management department within 10 days after modification. Driving an illegally modified car is against the law and will not pass the annual inspection.

I've always been an experienced driver, having driven many cars over the years and modified several myself. To make a modified car street-legal, you first need to understand the rules: changing tires or rims is allowed, but they can't exceed the original factory size; repainting the body is also fine, but you must register the new color code with the DMV. The key point is not to tamper with the engine or exhaust system, as those modifications can disrupt emissions and lead to fines if caught by traffic police. My friend once made reckless modifications and failed the annual inspection, wasting his money. I recommend consulting a certified auto shop before modifying and doing a small test. After modifications, be sure to conduct a safety inspection to ensure the brakes and lights are functioning properly. Also, contact your insurance company to update the policy, or you won’t be covered in case of an accident. Overall, safety comes first—don’t take risks. My experience with modifying cars is to follow the rules, and now I drive smoothly and safely.

I'm a car enthusiast who loves customizing my car's appearance to make it cooler and more unique. But keeping it street-legal is actually quite simple: start with minor modifications like installing stylish rims or applying a vinyl wrap for color change. Under Chinese regulations, changing the vehicle's color requires visiting the DMV with your ID card to complete some paperwork - just filling out a form will do the trick. Never modify the exhaust muffler though, as that noisy modification is illegal. Interior upgrades like adding audio systems or seats are permitted, but make sure they don't obstruct the dashboard instruments. From my personal experience, always test drive the modified car several times to check for any electrical shorts. The most crucial step is consulting your local traffic regulations website and following their guidelines. Major engine performance modifications could easily get your car impounded. Remember, legal modifications let you show style without fines, and safe driving should always come first.

Modified vehicles must ensure safety and reliability, and cannot be altered recklessly. According to traffic laws, legal modifications must adhere to the following: tire specifications must match the original factory settings, and body decorations must not affect driving stability. If headlights or suspension systems are modified, professional inspection is required to confirm they are safe. I've seen cases of accidents caused by illegal modifications when helping others with inspections. It's recommended to have the vehicle tested at an official inspection station before it can be legally driven on the road. Don't overlook small details like loose screws, which can easily lead to risks. Addressing issues promptly can prevent disasters.

Under What Circumstances Is a Wheel Alignment Needed?

Here are the situations where a wheel alignment is necessary: 1. Whenever suspension system components are disassembled or replaced, a wheel alignment must be performed. Examples include replacing shock absorbers, steering ball joints, or removing/installing the subframe. 2. Additionally, if the vehicle exhibits symptoms such as pulling to one side while driving, an off-center steering wheel, uneven tire wear, heavy steering, or failure of the steering wheel to return to center automatically, the first step should be to check whether the wheel alignment is correct. Below is a brief introduction to wheel alignment: 1. Ordinary passenger vehicles have four wheels, with the two front wheels being the steering wheels. These wheels are not randomly installed on the vehicle but have specific fixed installation relationships. The relative positioning between the wheels, steering knuckles (also known as "kingpins"), and axles is referred to as wheel alignment. 2. For front (steering) wheels, alignment includes four main parameters: caster angle, kingpin inclination, camber angle, and toe angle. For rear wheels, alignment consists of camber angle and toe angle. In rear-wheel-drive vehicles, there is an additional critical parameter called the thrust angle. The combination of front and rear wheel alignment is collectively known as four-wheel alignment.

Can the original battery of Nissan Sylphy be left unused for a long time?

The original battery of Nissan Sylphy cannot be left unused for a long time. Here is the relevant information: 1. The original battery of Nissan Sylphy cannot be left unused for a long time, as the battery may become too weak to start the car after prolonged inactivity. It is necessary to check it in time and replace it with a new one if needed. 2. To prevent the car battery from discharging due to long-term parking, the best practice is to start the car regularly and let the car's built-in generator charge the battery. If the battery is in good condition, starting the car once every half month and running it at about 2,000 rpm for about half an hour can basically replenish the self-discharge of the battery. If the battery's technical condition is not good, it is best to start the car once a week. 3. Modern cars do not recommend disconnecting the battery connection line. On one hand, after disconnecting the line, the car's anti-theft system will stop working, posing a risk of theft or damage to the car. On the other hand, after the battery is disconnected, many settings on the car will be lost and need to be reset when the car is used again. Some cars even require a special computer to reset the engine control unit system before they can be started after the battery is disconnected, which is not worth the effort.

What are the symptoms of spark plug aging?

Symptoms of spark plug aging: Difficulty starting, low power, excessive exhaust emissions, increased fuel consumption. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, remove the high-voltage distributor wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for external debris like leaves or dust and ensure thorough cleaning. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage distributor wires according to the firing order and secure the cover. Methods to determine if a spark plug is damaged: Remove the spark plug and observe its condition based on the following appearance colors. A normal spark plug's insulator skirt and electrodes appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has a reddish-brown insulator skirt, with an electrode gap between 0.8-0.9mm and no signs of electrode burn. If the spark plug has oil stains or deposits but is not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged, showing signs like blistering at the top, black streaks, cracks, or melted electrodes, identify the cause of the damage. After troubleshooting, replace the spark plug. Additionally, if the spark plug appears black as if smoked, it indicates the wrong heat range was selected or the air-fuel mixture is too rich, with oil creeping up.
