Can I park in the blue parking spaces on the roadside?

You can park in the blue parking spaces on the roadside. Here is some relevant information about blue parking spaces: 1. Introduction: Blue parking spaces indicate free motor vehicle parking spaces or non-motor vehicle parking spaces, which are marked as free parking spaces. If the blue line is dashed, it means free parking is only allowed for a limited time, while a solid blue line allows long-term free parking. Note that even if the line is solid blue, it is best not to park for more than a day, otherwise you may still receive a ticket. 2. Parking space colors: There are three types of parking space markings: blue, white, and yellow. Blue represents free parking spaces, white represents paid parking spaces (some may be free at night), and yellow represents special vehicle parking spaces (such as fire trucks). Parking spaces with yellow markings usually allow temporary parking but absolutely prohibit long-term parking.

Causes of Road Potholes?

Generally, potholes are caused by substandard foundation treatment, while smaller potholes require analysis of the conditions during pouring. Below is an introduction to the causes of road potholes: 1. Causes: Analyze the conditions during pouring, such as concrete quality, pouring methods, and curing conditions. 2. Solutions: Local damage to cement concrete pavements, if not repaired promptly and effectively, will lead to rapid deterioration. Regular maintenance, including road surface cleaning and joint clearing, is essential. Concrete pavements must be frequently swept to prevent the accumulation of gravel and other hard objects, which can cause cracks or potholes due to repeated wheel pressure. To prevent joint failure, aged or damaged sealants must be replaced in a timely manner.

What Causes the Regular Humming Sound from Tires?

The main reasons for a humming sound during vehicle driving are as follows: 1. Abnormal noise due to excessive tire pressure: Daily driving requires adjusting tire pressure within the standard range (usually 2.3bar-2.5bar). Overinflated tires can cause severe wear on the tread, reducing the tire's shock absorption and buffering performance, and significantly increasing tire noise. 2. Abnormal noise due to uneven tire wear: The tread area of the tire contacts and rubs against the ground. If the tread wears unevenly with bumps or irregularities, it can produce a humming sound. 3. Abnormal noise from damaged wheel hub bearings: Worn wheel hub bearings can generate a humming sound, primarily due to long-term use leading to wear and looseness. To protect wheel hub bearings, avoid harsh impacts on the wheels and prolonged driving through water during daily use.

Why does the car still go so fast when the clutch is fully depressed?

Because the previous state was acceleration, fully depressing the clutch means the power supply is cut off. However, on flat ground or downhill, the car will first deplete the acceleration from the previous process before it starts to decelerate. Here is some related knowledge about depressing the clutch: 1. Principle: It's quite simple, it's about the interaction of forces. Before depressing the clutch, the gear output force drives the wheels forward, providing both forward momentum and resistance since the wheels are connected to the gear. When the clutch is depressed, although the power is cut off, the resistance is also eliminated. Therefore, on relatively flat roads, there might be a temporary speed increase. If going downhill, the car will roll even faster, but coasting downhill is too dangerous and should be avoided. 2. Clutch Introduction: The function of the clutch is to disconnect the engine from the wheels. In other words, fully depressing the clutch means the engine is idling, and the wheels receive no driving force. When starting, depressing the clutch completely separates the engine from the wheels, and the car won't move as the engine idles. At high speeds, when the throttle is not pressed, the engine is actually being turned by the wheels. Depressing the clutch at this time removes the engine's resistance.

Is it a problem if the side of the tire has a small cut?

Generally, it's not a big issue. However, it's best to inspect the side carefully. Here is some relevant knowledge about tire sidewall damage: 1. Introduction The weakest part of a tire is the sidewall. Most tires only have one or, in rare cases, two thin layers of fabric reinforcement. If the sidewall is deeply damaged or shows signs of bulging, it is recommended to replace the tire promptly to prevent a blowout. If the spare tire is full-size, you can purchase a new one and use it on the same axle as the spare. It is essential to choose a tire of the same brand, model, size, tread pattern, and grade. For non-full-size spare tires, the tread wear should be roughly consistent. When the original tire's tread wear is excessive, it is advisable to buy a pair of new tires for replacement. It is recommended to install the new tires on the rear axle, as this helps prevent oversteer at certain speeds, making it easier to control the vehicle and avoid skidding or loss of control. 2.

Additionally, in rainy or snowy weather, insufficient rear tire grip can cause drifting, while insufficient front tire grip can usually be corrected by steering, but rear tire grip loss is generally harder to control.

Where to Go for Car Viewing When Buying a Car?

You can visit local 4S stores for car viewing. Here are some considerations when viewing cars: 1. Budget: Prepare a budget in advance. When selecting a vehicle, check the engine number to avoid purchasing a refurbished car. 2. Test Drive: During a test drive, you can assess how easy it is to operate the vehicle, as well as the noise insulation and shock absorption effects, which can be immediately felt while driving. Besides the driver's comfort, the sense of space in the rear seats and the comfort of the seats are also very important. Experience the rear seating space to see if there's any sense of confinement, whether the interior materials feel low-grade, and if the design is reasonable. 3. Pricing: You can inquire in advance with the salesperson about any discounts or promotional activities. Cars often come with promotions. When asking about the price, clarify whether it's the ex-factory price or the on-the-road price to avoid exceeding your budget. Also, ask how many free maintenance services are included.
