What does the driver's license clearance date mean?

The driver's license clearance date refers to the date when the accumulated penalty points can be cleared if the driver has not reached the maximum of 12 points before the annual inspection. Below is a detailed introduction about the driver's license clearance date: 1. The cumulative penalty points period for road traffic violations is 12 months, with a maximum of 12 points, calculated from the initial issuance date of the motor vehicle driver's license. 2. This is the meaning of the scoring cycle. For example, if the driver's license was obtained on June 18, then April 1 of the following year would be a scoring cycle, starting from June 18 of the following year until the next scoring cycle. 3. Based on the severity of the road traffic violation, the points deducted for a single violation can be one of the following five types: 12 points, 6 points, 3 points, 2 points, or 1 point.

At what voltage does a car battery fail to start the engine?

When the open-circuit voltage of a car battery drops below 12.2V and the load voltage falls under 9.5V, the vehicle will be difficult to start. Car owners should regularly inspect their car batteries by checking the observation window on the battery. If the window displays black, it indicates the need for charging; green signifies good condition, while white suggests insufficient electrolyte. Precautions for car battery usage: 1. Monitor battery lifespan: If a car battery has been in use for over 3 to 4 years, it should be replaced. Prolonged use diminishes its charge storage capacity, necessitating timely replacement. An overused battery may experience power depletion, preventing the vehicle from starting and disrupting normal use. 2. For vehicles left unused for extended periods: Fully charge the battery beforehand and start the vehicle once a month, then drive at moderate speed for a while to recharge the battery. Long-term storage may lead to battery depletion; if possible, remove and store the battery in a well-ventilated area with moderate temperature. 3. Time control: Limit each engine start attempt to 3-5 seconds to avoid damaging the battery. If the vehicle fails to start after several attempts, inspect the ignition system instead of repeatedly trying to start the engine.

Can the sunroof leakage of Volkswagen Lavida reach the floor inside the car?

Volkswagen Lavida sunroof leakage can reach the floor inside the car. Here are the relevant details about Volkswagen Lavida sunroof leakage: 1. Causes of Volkswagen Lavida sunroof leakage: Aging or cracking of the rubber sealing strip around the sunroof edge leads to poor sealing, resulting in leakage; Lack of lubrication and maintenance on the sunroof tracks on both sides; Blockage or breakage of the drainage pipe, as the outlet of the car sunroof is small, even a little sand or stone can easily cause blockage. 2. Solutions for Volkswagen Lavida sunroof leakage: Check whether the sealing strip is severely damaged or deformed, and replace it if necessary. Pay attention to the maintenance of the rubber sealing strip around the sunroof edge, and you can purchase a bottle of rubber protector to prevent the rubber from being eroded; Apply a small amount of lubricant to the sunroof track, and then spread it evenly, so that the sunroof can be opened and closed smoothly.

Which Lights to Use When Driving in the Rain?

When the rain is light, you should use the width indicator lights. When the rain is heavy, you should turn on the headlights or front fog lights, and avoid using hazard lights while driving. Also, do not use the side marker lights for extended periods. Below are the lights to use in different scenarios: 1. Use width indicator lights when the rain is light: The use of lights when driving in the rain is very particular. At the beginning of the rain, the sky is relatively dark, but visibility is still decent. In this case, you should use the width indicator lights. 2. Turn on the headlights or front fog lights when the rain is heavy: When the rain is heavier, the rainwater itself will obstruct your vision. Additionally, water on the road will be splashed up by the rolling tires of the vehicle in front, creating a mist that can significantly affect visibility. In this situation, you should turn on the headlights or front fog lights. 3. Use rear fog lights during heavy rain: Rear fog lights should only be used when the rain is extremely heavy because the red taillights already have excellent penetration power, and ordinary heavy rain usually doesn’t block their light. Rear fog lights are very bright and are designed to penetrate thick fog.

What Causes the Abnormal Noise When Accelerating with AC On?

When accelerating with the air conditioning on, the car may produce a humming noise. The specific reasons are as follows: 1. Insufficient vehicle power: Generally, when driving at too low a speed with too high a gear, occasionally pressing the accelerator may cause a humming noise accompanied by overall vehicle vibration. This is a clear signal that the gear is too high, the transmission ratio is too small, and the engine torque is insufficient for acceleration, leading to unstable engine speed and overall vehicle vibration. If the air conditioning is on, the compressor will consume power, diverting part of the engine's output energy to the AC system, which can result in noticeable power shortage during acceleration and cause the engine to produce a humming noise. 2. Engine fan operation: Turning on the AC increases the engine load, causing the engine temperature to rise quickly. To dissipate heat from the AC system, the vehicle's cooling fan will activate. The fan's operation generates significant noise, which, combined with the engine's sound, can be heard as a humming noise in the cabin. 3. AC damage causing abnormal compressor operation: If the AC compressor is internally worn or contains foreign objects, its rotation under the belt's drive may become irregular. When the AC is on, abnormal compressor rotation can definitely cause unusual noises in the vehicle.
