Can I get my car inspected without an ID card?

An ID card is not required for the annual vehicle inspection, so you can have your car inspected without one. Here are some details about the annual inspection: 1. For the annual inspection, you only need to bring your vehicle license and compulsory traffic insurance policy. 2. Before the inspection, you must settle any traffic violations; otherwise, the inspection cannot be passed. 3. During the inspection, your vehicle needs to be driven onto the inspection line, where professionals and specialized equipment will check it. 4. The inspection includes checking the vehicle's appearance, exhaust emissions, chassis, braking system, and lighting system. 5. When inspecting the lighting system, special attention is paid to the brake lights, reverse lights, and turn signals. 6. If your vehicle has any exterior modifications, they must be restored to the original condition before the inspection; otherwise, the inspection cannot be passed. If you fail to complete the annual inspection on time and are caught driving by traffic police, you will be fined and receive penalty points.

Which Type of Car Transmission is the Best?

DCT (Dual Clutch Transmission) is currently the most widely used transmission. Below is a detailed introduction to various types of transmissions: 1. MT (Manual Transmission): Also known as manual gearbox. It requires the driver to manually shift the gear lever to change the gear engagement inside the transmission and control the clutch engagement with the foot to alter the gear ratio, thereby achieving gear shifting. The gear lever can only be moved when the clutch is depressed. If the driver is skilled, a car with a manual transmission can accelerate and overtake faster than an automatic transmission car and is also more fuel-efficient. The advantages of this transmission are its affordability and the driving pleasure it offers. 2. AT (Automatic Transmission): Uses planetary gear sets and a torque converter for gear shifting, replacing the traditional clutch and freeing the driver's left foot. It determines the optimal gear based on parameters like speed, throttle, and driver commands. Favored by Japanese automakers for its low fuel consumption and economic efficiency, the downside of this transmission is its noticeable gearshift jerking. 3. CVT (Continuously Variable Transmission): Unlike gear-based transmissions, CVT uses a steel belt to connect the input and output shafts, enabling seamless gear ratio changes. This design gives CVT the smoothest shifting performance among all transmissions, along with a simple structure and easy maintenance. However, CVT transmissions have long been criticized for their lower transmission efficiency and inability to handle heavy loads, which can lead to slipping. 4. DCT (Dual Clutch Transmission): As the name suggests, it features two clutches, resembling the combination of two AT transmissions. In a DCT, there are two clutches—K1 and K2. K1 controls gears 1, 3, and 5, while K2 controls gears 2, 4, and 6. During acceleration, the two clutches alternate, making DCT transmissions more efficient in gear shifting. However, they also suffer from gearshift jerking and other drawbacks.

How to Steer When Turning a Car?

Operation method for sharp turns: When steering on sharp curves, you can use the method of turning the steering wheel at a large angle with alternating hands. For example, when turning right, pull the steering wheel with your right hand to between the 5 and 6 o'clock positions and release it, then grasp between the 10 and 11 o'clock positions with your right hand over your right wrist to pull the steering wheel, while moving your left hand to between the 6 and 7 o'clock positions to continue pushing the steering wheel. Special reminder: When the wheels skid to the right, avoid turning the steering wheel to the left to prevent lateral skidding. The opposite applies when the wheels skid to the left. When steering on sharp curves, you can use the method of turning the steering wheel at a large angle with alternating hands, commonly referred to as "large alternating grip". Operation method for gentle turns: 1. When turning on relatively straight and gentle curves, you can keep your hands in the same position on the steering wheel and turn it simultaneously. 2. Both hands should be positioned on the left and right sides of the steering wheel rim, with thumbs naturally extended upward and resting against the rim, and the other four fingers gripping the rim from the outside inward. Sudden steering and quick return method: Often used when the vehicle skids on muddy roads. When the wheels skid to the right, immediately release the accelerator pedal, turn the steering wheel sharply to the right and hold it firmly. When the rear of the vehicle returns to a straight line, straighten the steering wheel and control the speed, ensuring that the steering wheel does not swing left and right.

Why is there a lot of noise when driving at high speed on the highway?

The reasons for excessive noise when driving at high speed on the highway are as follows: 1. Tire noise: The tires are filled with air, creating a certain atmospheric pressure that forms a sealed small-body pressure. At high speeds, the rapid rotation of the tires, combined with the high pressure inside and the fast friction between the tire surface and the road, generates noise. 2. Engine noise: Driving on the highway requires the engine to produce higher torque, which leads to an increase in RPM, one to two times higher than usual. This causes the engine to emit a high-pitched whining sound. Since the engine is mounted at the front of the car, near the driver's compartment, the noise is more noticeable. Some cars lack sound-absorbing foam on the hood, and the metal panels connecting the engine compartment may not have sufficient insulation or fireproof padding, leading to noise transmission into the cabin. Adding soundproofing foam to the door panels can improve noise insulation. 3. Wind noise: High-speed driving increases wind resistance, which is related to the vehicle's design. For example, SUVs are more affected by wind. If the car's body has damage, high-speed driving can cause noise through gaps or cracks in the structure.

How Many Class Hours Are Required for Driving License Subject 1?

Subject 1: 12 class hours of training. It is theoretical training, mainly to understand the basic knowledge of motor vehicles and master the regulations of road traffic safety laws, regulations, and road traffic signals. The class hours for other subjects are as follows: 1. Subject 2: 26 class hours of training. 2 class hours for theoretical knowledge and 24 class hours for practical operation, including 8 class hours required for reversing into a garage, stopping and starting on a slope, parallel parking, curve driving, and turning at a right angle. 2. Subject 3: 40 class hours of training. 16 class hours are required for road driving skills and safe and civilized driving knowledge, and 24 class hours are required for the practical operation of road driving skills.

What does 'Check TPMS' mean?

The 'Check TPMS' warning indicates that the pressure in one of your tires may be too low. Immediately reduce your speed and avoid sharp steering or sudden braking, then check the tire pressure. Here is some relevant information: 1. TPMS stands for Tire Pressure Monitoring System. 2. There are two types of tire pressure monitoring systems based on different monitoring principles. 3. The first is a direct TPMS, which uses pressure sensors installed in each tire to directly measure tire pressure. The system transmits pressure information from inside the tire to a central receiver module via wireless transmitters, then displays the tire pressure data for each tire. The system will automatically issue an alert when tire pressure is too low or if there is a leak. 4. The second is an indirect TPMS. When the pressure in a tire decreases, the vehicle's weight causes that tire's rolling radius to become smaller, making it rotate faster than the other wheels. By comparing the rotational speed differences between tires, the system monitors tire pressure. Indirect tire alert systems actually rely on calculating the tire's rolling radius to monitor pressure.
