What are the penalties for crossing a solid white line on the highway?

Crossing a solid white line on the highway will result in a 3-point deduction from the driver's license and a fine ranging from 20 to 200 yuan. In addition to prohibiting lane changes, solid lines on highways also forbid U-turns and turns, which are common mistakes made by new drivers. Therefore, when driving on highways, it's essential to slow down and maintain a safe speed, allowing more time to react and correct course to avoid traffic violations. Generally speaking, whether it's a single yellow, solid white line, or double yellow and white solid lines, none should be crossed. Sometimes, changing lanes over solid lines on highways can be captured by cameras, especially in accident-prone areas where numerous traffic violation cameras are often installed. Drivers should reduce speed and remain vigilant when passing through these sections to ensure safe passage.

How to Distinguish Tire Models and What Do They Represent?

Tire models can be distinguished by looking at the sidewall markings. Currently, almost all passenger car tires are radial tires. The specifications of radial passenger car tires are labeled in the order of "tire width, aspect ratio, compatible rim diameter, load index, and speed rating." The parameters displayed on the tire model represent the tire's width, aspect ratio, tire type, and applicable size. Taking the model 225/60R17 as an example, 225 indicates the tire's section width is 225mm, 60 is the aspect ratio, meaning the tire's sidewall height is 60% of the section width, R stands for radial tire, and 17 indicates the tire is suitable for 17-inch rims.

Can a person without a driver's license buy a car and register it under their own name?

A person without a driver's license can buy a car and register it under their own name. Not having a driver's license does not affect the owner's ability to register the vehicle. Only an ID card is required for the purchase, including obtaining license plates and purchasing insurance—none of these require a driver's license. The vehicle owner must fill out the motor vehicle registration application form and submit the required documents to the local vehicle management office at their place of residence to apply for vehicle registration and inspection. Documents required for registration include: 1. Proof of identity of the vehicle owner; 2. Proof of vehicle origin, such as the purchase invoice; 3. Proof of compliance for the whole vehicle from the manufacturer or import documentation for imported vehicles; 4. Proof of payment or exemption for vehicle purchase tax; 5. Proof of compulsory motor vehicle liability insurance; 6. Proof of payment or exemption for vehicle and vessel tax; 7. Other proofs or documents required by laws and regulations for motor vehicle registration.

How to Handle Points Deduction for A2 Driving License?

If the points deducted from an A2 driving license are less than 12, the driver should promptly pay the fine and, within 30 days after the end of the scoring cycle, report to the traffic management department of the public security authority for verification. During verification, the driver must participate in study sessions and examinations. Any points for which fines have not been paid, even if the total points do not reach 12, will be carried over to the next scoring cycle. If the points deducted from an A2 driving license reach 12, the driver must, within 15 days, attend a seven-day study session on road traffic safety laws, regulations, and related knowledge at the traffic management department of the public security authority where the motor vehicle driving license was issued or where the violation occurred. Additionally, within 30 days, the driver must apply for a downgrade and license replacement. If the driver fails to complete the downgrade and license replacement within the specified time, the vehicle management office will announce the invalidation of the driving qualification for the corresponding vehicle type.

Does an illegal parking notice deduct points?

What is the mnemonic for gear shifting techniques for beginners?

Mnemonic for gear shifting techniques for beginners: 1. Start in first gear - After getting in the car, fasten the seatbelt, hold the steering wheel with the left hand, fully depress the clutch with the left foot, place the right hand on the gear lever to engage first gear, release the handbrake, then gradually release the clutch to start moving slowly. 2. Shift gears progressively - Start in first gear, immediately shift to second gear once the car moves, shift to third gear when speed exceeds 20 mph (no need for fourth gear), and directly jump to fifth gear when speed reaches 45 mph. 3. Keep eyes on the road - Beginners may instinctively look at the dashboard or gear lever while shifting, which is dangerous. Always maintain forward vision. When shifting, release the accelerator with the right foot, wait for stable speed, depress the clutch with the left foot, promptly change gears with the right hand while keeping the left hand firmly on the steering wheel.
