New car brake noise when reversing is the sound of wear between the brake pads and discs. After driving for a while to break them in, the noise will stop, which is completely normal. The main reasons for brake noise generally include: 1. The break-in period of new brake pads is a crucial stage, usually requiring several hundred kilometers of driving before the brakes feel more comfortable; 2. Newly replaced brake pads also need a break-in period to better integrate with the old discs; 3. Tiny sand particles may enter between the pads and discs during driving, causing noise due to friction; 4. Missing or damaged brake disc mounting screws; 5. Malfunction in the brake system.

How many points are deducted for driving in the wrong direction on a highway?

Driving in the wrong direction on a highway results in a deduction of 12 points and a fine, and may also lead to a 12-month suspension of the driver's license. Administrative penalties may also be imposed. The penalties for driving in the wrong direction on a highway are more severe than under normal circumstances. The specific penalty is an immediate deduction of 12 points, and there are other situations that may also result in point deductions. After losing all points, the driver must undergo re-education. Below are precautions for driving on a highway: 1. Drive in the designated lane: Highways have clearly marked lanes for different types of vehicles, such as large vehicles and small cars. When overtaking, once you occupy a lane, return to your own lane promptly after completing the maneuver and avoid occupying other lanes for extended periods. Additionally, the emergency lane should not be occupied for long periods without special reasons. 2. Maintain a safe speed and avoid speeding: The dangers of speeding are well-known, whether on local roads or highways, as it can lead to irreversible consequences. 3. Maintain a safe following distance: Generally, on dry roads with good braking conditions, the following distance (in meters) should not be less than the speed (in km/h). For example, at 80 km/h, the distance should be no less than 80 meters, and at 100 km/h, no less than 100 meters. Always pay attention to roadside signs indicating following distances. In rainy, foggy, snowy, or wet road conditions, the following distance should be more than doubled. 4. Observe traffic signs: Always pay attention to roadside and overhead signs and markings while driving, and stay appropriately to the right to avoid running over the right lane divider, ensuring sufficient lateral distance for vehicles overtaking from behind. 5. Do not arbitrarily occupy the emergency lane in case of a traffic accident: Traffic accidents are inevitable on highways. If other vehicles cause an accident that blocks the driving lane, do not occupy the emergency lane without reason, as this may hinder rescue vehicles from performing their duties. 6. Avoid fatigue driving and take timely breaks: Fatigue driving is extremely dangerous on highways. When fatigued, a driver's reaction time slows, making it difficult to respond correctly to sudden situations.

Can You Drive Without Carrying a Driver's License?

If you have a driver's license but forget to bring it, you need to show your vehicle registration certificate and ID card to the traffic police for verification. However, you may still face a fine or penalty points. Here is an introduction to driver's licenses: 1. C1 Driver's License Regulations: Driving an electric tricycle with a C1 driver's license is considered a mismatch of the permitted vehicle type. Driving a vehicle that does not match the permitted type is penalized as driving without a license, with a fine ranging from 200 to 2,000 RMB and possibly up to 15 days of detention. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," driving a vehicle that does not match the permitted type results in 12 penalty points. 2.

Where is the windshield washer fluid reservoir located in a Buick?

In Buick vehicles, the windshield washer fluid reservoir is located on the left side of the engine compartment. It is a small blue-capped container marked with a windshield washer symbol. Simply open the cap and pour in the windshield washer fluid. Cleaning performance: Windshield washer fluid is formulated with various surfactants and additives. Surfactants typically have functions such as wetting, penetrating, and solubilizing, thereby providing cleaning and stain removal effects. Antifreeze performance: It significantly lowers the freezing point of the liquid, providing antifreeze protection and quickly dissolving frost. Anti-fog performance: A single-molecule protective layer forms on the glass surface. This protective film prevents the formation of fog droplets, ensuring the windshield remains clear and transparent for optimal visibility. Lubrication performance: With higher viscosity, it acts as a lubricant, reducing friction between the wiper blades and the glass to prevent scratches. Precautions for adding windshield washer fluid to your car: Pay attention to the capacity of the windshield washer fluid reservoir. When adding fluid, avoid filling it to the brim in one go, but also don't add too little to prevent overflow. The type of windshield washer fluid used varies by season. The choice depends mainly on temperature; for example, in winter, use a fluid that can prevent freezing, while in summer, opt for one with stronger cleaning capabilities. Avoid frequently switching brands of windshield washer fluid, as different brands may have varying compositions. Frequent changes could cause reactions between residual and new fluids, affecting performance.
