When the car brakes squeak, the following are the reasons why it worsens on rainy days: 1. Fine sand adheres to the brake disc: Rainwater carries fine sand that sticks to the brake disc. In humid weather or when there is a large temperature difference between day and night, dew or rain can cause the brake disc to rust, which acts like tiny particles. Car brake pads come in hard and soft varieties. Hard pads are more wear-resistant, but if there are tiny particles between the hard pads and the gray cast iron brake disc, they can produce a sharp squeaking sound. A few brake applications will wear off these small particles and the noise will stop. 2. Break-in period: The break-in of a new car includes an important phase for the brake pads. Typically, after driving a few hundred kilometers, the braking will feel more comfortable. Newly replaced brake pads also need a break-in period to better integrate with the old disc. Initially, the brakes may feel very stiff, and it usually takes a few hundred kilometers of driving before they feel better. 3. Missing brake disc fixing screws: Missing or damaged fixing screws on the brake disc can also cause brake noise.

Is the driving test scheduled by oneself or by the driving school?

The driving test can be scheduled either by oneself or by the driving school. The following are the relevant considerations for scheduling a driving test: 1. Training qualification: To schedule a driving test, one must have completed the training successfully. The student's exam admission ticket must be valid, and the training for the subject to be tested must be completed and concluded before scheduling. Students who cheat in the exam must wait one year before they can schedule again. The online system will automatically review the student's qualifications, and unqualified registration requests will be rejected. 2. Training hours requirement: Before scheduling, it is necessary to ensure that the required driving practice hours have been completed. Otherwise, during the online scheduling process, if the comparison of identity information reveals insufficient training hours, the appointment will be automatically canceled. 3. Scheduling time: Students must be aware of the test scheduling time for their driving school's group in advance and schedule online 20 days before this time. Online scheduling starts at 8 a.m. 20 days before each test, on a first-come, first-served basis until all slots are filled. Students should combine the test times of their respective driving schools to schedule online on time. After successful scheduling, please contact the driving school promptly to pay the fees and print the exam admission voucher.

Can You Turn Right at a Round Red Light?

There are three scenarios where vehicles can turn right at a red light, as detailed below: Round Traffic Light: If the round traffic light at an intersection turns red, vehicles in the right-turn lane can proceed to turn right. However, you must ensure not to interfere with other vehicles, pedestrians, and vehicles on the right side of the road. Arrow-shaped Right-turn Indicator: If you encounter an arrow-shaped right-turn signal at an intersection, you cannot turn right when the red arrow is lit. Turning right under these conditions will be considered running a red light. Round Red Light with Additional Signage: At some complex intersections, you may find additional signage above the traffic light indicating whether right turns are permitted during a red light. If the sign says "Right Turn on Red," you may proceed. If it says "No Right Turn on Red," you must wait for the green light. Legal Regulations: According to the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," motor vehicle and non-motor vehicle traffic signals are defined as follows: When the green light is on, vehicles are permitted to proceed, but turning vehicles must not obstruct the passage of straight-moving vehicles or pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue to proceed. When the red light is on, vehicles are prohibited from proceeding. At intersections without non-motor vehicle or pedestrian crossing signals, non-motor vehicles and pedestrians should follow the motor vehicle traffic signals. When the red light is on, right-turning vehicles may proceed if they do not obstruct the passage of other vehicles or pedestrians. According to the "Road Traffic Safety Law," the rules regarding traffic lights are as follows: Article 25, Paragraph 2 states that traffic signals include traffic lights, traffic signs, road markings, and the directions of traffic police. Article 26 specifies that traffic lights consist of red, green, and yellow lights. Red indicates prohibition, green indicates permission, and yellow serves as a warning. Article 38 requires that vehicles and pedestrians must follow traffic signals; when directed by traffic police on-site, they must follow the police's instructions; on roads without traffic signals, they should proceed under the principles of safety and smooth traffic flow. Article 62 states that pedestrians crossing intersections or roads should use crosswalks or pedestrian facilities; at signalized crosswalks, they must follow the traffic signals; at unsignalized intersections or road sections without pedestrian facilities, they should cross only after confirming safety. Article 89 stipulates that pedestrians, passengers, or non-motor vehicle drivers violating road traffic safety laws or regulations may receive a warning or a fine ranging from 5 to 50 yuan; non-motor vehicle drivers refusing to pay fines may have their vehicles impounded. Driving a motor vehicle in violation of traffic signals results in a 6-point penalty. Right-turn Precautions: Observe Straight-moving Vehicles from the Left: When turning right, check both the right and left sides for oncoming traffic. Watch for Left-turning Vehicles from the Opposite Direction: Besides straight-moving vehicles, also be aware of any left-turning vehicles from the opposite side. Yield to both left-turning and straight-moving vehicles from the left before proceeding. Pay Attention to Pedestrians: When turning right, be mindful of pedestrians on crosswalks, not only at the intersection but also at the corner where additional crosswalks may be present.

What does the Regal GS adaptive suspension mean?

Regal GS adaptive suspension refers to Buick's Full-Time Active Damping Control system. CDC Intelligent Suspension Positioning: The CDC intelligent suspension is not a patented technology of GM. This system was primarily developed by Opel based on European automakers' approaches for their vehicle models, utilizing supplier technology. The company providing this technology is called ZF Sachs, but it differs significantly from another intelligent suspension system under GM called MRC. CDC stands for Continuous Damping Control, which Buick refers to as the Full-Time Active Damping Control system. MRC stands for Magnetic Ride Control, which Cadillac calls the Active Magnetic Ride Control system. Its origins can be traced back to the SD2C speed-sensitive damping control system in the 1980s. Currently, it is exclusively applied to Cadillac-branded vehicles in China and is recognized as the fastest-responding system, bar none. Experience with CDC Intelligent Suspension: It better adapts to road conditions, though the difference may not be noticeably perceptible. The distinction might be more apparent during sharp cornering. Additionally, the Sport mode chassis feels more like a race car, resembling a performance vehicle more closely. Most mid-size or even compact cars offer a Sport mode, but this setting typically only affects transmission logic—maintaining a relatively higher engine RPM threshold, allowing drivers to achieve quicker and more responsive power output with light throttle input and delayed upshifts.
