How to Determine Whether a Car is New or Stock When Buying?

When buying a car, you can determine whether it is new or stock by checking the vehicle nameplate, tire wear, and manufacturing date. The vehicle nameplate is usually located below the B-pillar on the passenger side and includes information such as the manufacturer, model, engine power, total weight, serial number, manufacturing date, and manufacturer name. Check the manufacturing date; if the manufacturing date is within three months of the purchase date, it is not a stock car. If it exceeds three months, it can generally be considered a stock car. Generally, new cars have minimal tire wear, and the tread hairs on the tire walls are clearly visible. If you notice the absence of tread hairs on the tires, pay attention and then check the tire's manufacturing date. There is a series of numbers on the tire sidewall; the latter group represents the manufacturing year, and the former group represents the week, allowing you to calculate the tire's manufacturing date. Then, compare it with the vehicle's manufacturing date on the nameplate. If the dates are similar, it also proves that the car is not stock. If there is a significant time difference, you should be cautious.

Can I Apply for Extended Warranty When the Manufacturer Changes the Warranty Period?

When the manufacturer changes the warranty period, you cannot apply for an extended warranty because the warranty duration is set by the manufacturer (not less than the national mandatory requirement of 2 years or 50,000 kilometers), and the manufacturer has the right to modify the warranty period for its products. Coverage under the warranty: It mainly applies to the core components of the vehicle, such as the engine, transmission, drivetrain, and chassis. The failure rate of these parts is relatively low, and the repair costs are high. In five years, it is rare for these core components to develop issues. However, wear-and-tear parts like tires, rims, headlights, and brakes are only covered for 3-6 months or 5,000 kilometers. Maintenance considerations: If the owner does not take the new car for regular maintenance at the designated 4S shop or manufacturer-authorized service station within the specified mileage, any issues that arise—even within the warranty period—will require the owner to bear some repair costs. Additionally, if the owner alters the vehicle's purpose for commercial use, such as rental, leasing, or competitive racing, it will be considered an automatic forfeiture of warranty rights.

Which Subject is Most Likely to Fail in Driving Test Subject 2?

Parallel parking is the most complex part of the Subject 2 driving test. Here are specific techniques for Subject 2: Drive slowly: Maintaining slow speed is the fundamental rule for Subject 2 practice. Without stalling, keep the vehicle moving as slowly as possible - the slower the better, as this allows sufficient time for each adjustment. Adjust mirrors properly: After entering the vehicle, always adjust the mirrors carefully, which is particularly crucial for parallel parking and perpendicular parking. Master the three-point alignment method: The three points are the driver's eyes, reference points on the vehicle, and reference points on the ground. During Subject 2 operations, you must accurately identify these points and observe carefully to position correctly. Pay attention to vehicle corners: During parallel parking: the front corner may touch outside lines, the rear corner may touch side lines of parking space; during curve driving: front corners may cross lines; during right-angle turns: front corners may cross lines; during perpendicular parking: front corner may touch outside lines or left front corner of parking space, right rear corner may touch right parking space line. Therefore, always monitor the four corners relative to outer boundary lines.

What Symbol Indicates a Dead Car Battery?

When a car battery is dead, it will display a symbol resembling a battery. Below are some maintenance tips for car batteries: In-car electrical usage: To maintain your car battery, avoid activities like listening to the radio loudly, charging your phone, or using an air pump while the engine is off. Prolonged use of these devices can drain the battery, and frequent depletion significantly reduces its lifespan. Highway driving: Regular highway driving offers many benefits. Not only does it help remove carbon deposits from the vehicle, but it also allows the battery to charge fully. Generally, driving on the highway for over an hour can fully charge the battery, keeping it in optimal condition. Avoid prolonged inactivity: If the car is not used for an extended period, disconnect the battery cables or start the vehicle every two weeks and drive a few dozen kilometers to ensure the battery remains functional. High-power electrical connections: Many modern car accessories, such as car refrigerators, vacuum cleaners, and air pumps, have high instantaneous power demands. Avoid connecting these devices directly to the car battery. Instead, start the vehicle first before connecting any electrical equipment.

What Causes a Car to Break Down on the Highway?

Specific reasons for a car breaking down on the highway include transmission coasting in neutral, transmission gear grinding and jumping, and fuel pump circuit burnout. Transmission coasting in neutral: Increases friction in the shifting mechanism, damaging the transmission. When coasting in neutral with an automatic transmission, the difference between driving speed and engine speed can lead to insufficient oil pressure in the hydraulic lines, damaging the friction plates inside the automatic transmission, ultimately causing transmission failure and potentially leading to a breakdown. Transmission gear grinding and jumping: For automatic transmissions, shifting into Park without fully depressing the brake pedal. If the brake isn't fully engaged before shifting to Park and turning off the engine, it can impact the transmission gears. Over time, this shortens the transmission's lifespan. For manual transmissions, forcing a gear shift without fully depressing the clutch damages the transmission. Forced shifting encounters resistance from the friction and collision between the rapidly rotating gear teeth, causing significant damage. Fuel pump circuit burnout: Fuel pumps rely on the fuel itself for cooling. If the fuel level is too low, exposing the pump, it may overheat or even burn out the circuit. Prolonged exposure to such conditions can significantly reduce the fuel pump's lifespan.

Is Speeding a Violation of the Law?

Speeding is a violation of the law because, from the perspective of safe driving behavior, vehicles must not exceed the maximum speed limit set by law or the speed indicated by traffic signs. Specific manifestations of speeding include: Exceeding the maximum speed limit set for the road or the speed indicated by signs; competing with pedestrians at crosswalks; failing to slow down before turning or when passing through intersections; driving too closely to other vehicles, cutting in line, or jamming into traffic; failing to adhere to speed limits on highways; and not reducing speed when driving at night, in hazardous road sections, or under adverse weather conditions such as sandstorms, hail, rain, snow, fog, or icy roads. Penalties for speeding: The penalty for speeding is as follows: exceeding the speed limit by less than 10% results in no fine or demerit points; exceeding the speed limit by 10% to less than 20% incurs a fine and 3 demerit points; exceeding the speed limit by 20% to less than 50% incurs a fine and 3 demerit points; exceeding the speed limit by 50% or more incurs a fine and 6 demerit points, and may also result in the revocation of the driver's license. The amount of the fine varies depending on the extent of the speeding violation.
