Installing a steering wheel assist ball on a car is illegal. Relevant regulations: Traffic police remind that unauthorized installation of such small assist balls or other similar "mini steering wheel" devices on vehicles constitutes behavior that hinders safe driving. Once discovered, the owner must immediately remove it and will be fined a certain amount. Potential consequences of installation: In fact, such steering wheel assist balls are originally designed for forklifts operating in confined spaces like warehouses, where frequent rapid steering is required. For forklift operators, these small assist balls are both safe and convenient. However, applying this forklift driving method to road vehicles creates significant safety hazards. The overall size of the steering wheel assist ball is small, and if the driver's hands sweat and slip during operation, it can easily cause excessive vehicle sway and loss of control.

I think installing a steering wheel spinner mainly depends on regional regulations. As someone who drives frequently, I've heard experienced drivers mention that in many places, especially big cities, traffic laws are quite strict. Modifying steering wheel equipment like spinners, if it alters the original factory design, is considered illegal modification. This is because spinners change the leverage effect of steering—while they may seem to save effort, they can easily slip or lose control at high speeds, significantly increasing the risk of accidents during sharp turns. Once, I helped a friend install one, but during a traffic stop, the officer fined him 500 to 1,000 RMB and deducted 2 points for compromising vehicle safety performance. Safety first—don't prioritize convenience over safety. I recommend sticking to original factory parts or having a professional inspect the steering system to avoid trouble and danger. Long-term use of spinners can also accelerate wear on the steering wheel bearings, leading to costly repairs.

From what I understand, installing a steering wheel spinner knob might be illegal in many countries and regions - you'd need to check local traffic laws. I recall the regulations clearly stating that unauthorized modifications to vehicle control components, like adding steering wheel attachments, can result in fines or penalty points if they lack proper certification or compromise original safety standards. I tried using one during long drives and it did save some effort, especially in traffic jams, but at a checkpoint the police immediately warned me to remove it, citing non-standard modifications that disrupt vehicle balance and pose major safety risks. Driving isn't a game - the steering system shouldn't be tampered with. While it reduces effort, it increases the risk of losing control. I felt much safer after removing it. Worse still, if you get into an accident and the insurer discovers unauthorized modifications, they won't cover the damages, leaving you to pay repair costs yourself - that's real trouble.

What is the reason for white smoke coming from the exhaust pipe after carbon cleaning?

The reasons for white smoke coming from the exhaust pipe after carbon cleaning are: 1. Residual cleaning agent sprayed inside during cleaning; 2. When the vehicle is started, the residual cleaning agent will burn along with the fuel, and if the air-fuel mixture is too rich, it will produce white smoke. The exhaust pipe is installed between the engine exhaust manifold and the muffler, allowing the entire exhaust system to have flexible connections, thereby reducing vibration and noise, facilitating installation, and extending the life of the exhaust muffler system. The maintenance methods for the exhaust pipe are: 1. Regularly check if the exhaust pipe is cracked; 2. Regularly inspect the exhaust pipe for abnormal noises; 3. Regularly check for any foreign objects inside the exhaust pipe; 4. Let the engine idle for 10 minutes before starting to expel accumulated water inside.

How are license plates ending with letters restricted?

Vehicles with license plates ending in English letters are managed as even-numbered plates. Within urban areas, odd-even license plate restrictions are implemented, with odd-numbered plates allowed on odd days and even-numbered plates on even days. Based on the last Arabic digit of the vehicle license plate (including temporary plates), they are divided into five groups. On Mondays, plates ending with "1" and "6" are restricted. The odd-even driving restriction is implemented 24 hours a day, with plates ending in letters or Chinese characters managed as even-numbered plates. Vehicle license plates ending with English letters are managed as number "0".

How to Perform Front-First Parallel Parking?

First, drive past the parking space to assess whether it can accommodate your vehicle. Quickly shift your gaze from the right rearview mirror to the left rearview mirror, paying attention to oncoming traffic and obstacles on the left side. While turning the steering wheel fully, slowly reverse until the left rearview mirror can completely see the front of the car behind you, then straighten the wheels and continue reversing. Observe the distance between the right rear wheel and the curb. When it seems appropriate, turn the steering wheel fully to the left and try to get the car as close to the curb as possible. Once most of the car is in the parking space, the driver should determine the distance from the car behind by turning their head or using the parking assist system.

What are the causes of abnormal noises from the chassis on bumpy roads?

The causes of abnormal noises from the chassis on bumpy roads are: 1. Exhaust or engine failure; 2. Aging of the shock absorber top buffer block and lower control arm bushings; 3. Damage to the stabilizer bar links; 4. Loose chassis suspension system. The function of the car chassis is to support and install the car engine and its various components and assemblies, form the body shape, receive the power from the engine, enable the car to move, and maintain normal driving. The car chassis consists of the transmission system, steering system, running system, and braking system. Methods for maintaining the car chassis: 1. Regularly check the oil condition of important assemblies; 2. Pay attention to the wear of brake pads and clutch plates; 3. Perform four-wheel alignment regularly; 4. Monitor tire pressure and wear condition.

What to Do When Your Car Is Submerged in Water?

During heavy rain, if your car is submerged, the first priority is to quickly exit the vehicle and move to higher, safer ground. After the heavy rain and floodwaters recede, do not attempt to power on or start the vehicle, especially for high-end brands and models. Tow the vehicle to a 4S shop or repair shop for a comprehensive inspection to assess the extent and scope of the water damage, including checking whether water has entered the engine's air intake. Clean the affected systems and components, ensuring that absorbent parts are deodorized and dried to prevent mold growth later on. Once the vehicle is thoroughly cleaned and free of residual moisture and dampness, proceed with power-on testing. If necessary, replace any damaged electrical components.
