The causes of belt noise during cold start are: 1. The belt tightens due to low temperature before ignition, resulting in noise; 2. Severe belt aging with its service life nearing the limit; 3. The belt is either too loose or too tight. The functions of the belt are: 1. Ensuring accurate intake and exhaust timing; 2. Synchronizing engine ignition with cylinder movement; 3.

Is it allowed to change lanes on a solid line?

Under special circumstances, it is permissible to change lanes on a solid line. Otherwise, changing lanes on a solid line is prohibited. Crossing a solid white line to change lanes is considered a violation and is subject to penalties, typically a fine of 200 RMB and 3 demerit points. If an accident occurs due to improperly crossing a solid white line to change lanes, the driver will bear primary responsibility. Below are details about driving under special circumstances: If the vehicle ahead breaks down and turns on hazard lights, causing congestion behind and prolonged stagnation, vehicles may cross the solid white line to change lanes, provided safety is ensured. Usually, in such cases, traffic police will be present to direct traffic, and drivers should follow their instructions. However, if there is no traffic police on-site and the violation is captured by electronic monitoring, resulting in a penalty notice, the driver can appeal through administrative reconsideration to have the penalty dismissed.

How Long Does It Usually Take to Repair Car Paint?

Car paint repair generally takes one day. If the scratches are not severe, a quick spray method can be used, which takes 3-4 hours, allowing you to pick up the car in the morning or afternoon. The drying speed of the paint after spraying is directly related to the season. With sufficient ventilation and humidity, the paint will dry in 6 hours. If baking is used, the drying speed can be accelerated, and the paint will dry in 2-3 hours. Car paint repair based on the severity of scratches: For minor scratches that only affect the surface layer of the car paint without damaging the primer or structure, it is best for new cars to go to a 4S shop for warranty repair. For older cars, you can visit an auto beauty shop and use waxing to repair the paint. Depending on the extent of the paint damage, either coarse wax or fine wax is used, followed by polishing with a polishing machine to restore the paint surface. For severe scratches, where there are multiple scratches on the car surface or the scratches are deep enough to damage the primer or the vehicle's structure, immediate repair at a 4S shop is necessary. If left unrepaired for too long, the scratched paint surface may rust. Once rusted, even if repaired later, the internal metal may continue to rust, leading to issues such as paint peeling.

Can a driver's license be renewed in a different location when it expires?

Driver's license renewal upon expiration can be processed in a different location. It is necessary to renew the license promptly, as failure to do so may result in its cancellation. Article 57 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" stipulates that motor vehicle drivers should apply for renewal at the vehicle management office of the license issuing location or another location within 90 days before the expiration of the motor vehicle driver's license. The following are precautions for using a driver's license: 1. Driver's licenses have an expiration date: Driver's licenses are only valid within their expiration period, and driving with an expired license is illegal. 2. Avoid accumulating 12 penalty points within 12 months: A driver's license has 12 penalty points available within a 12-month period. It is important to avoid accumulating all 12 points within this timeframe, as this would require attending a training session at the local vehicle management office and passing an exam. If the exam is not passed, the driver must continue taking it until successful, after which the license can be reclaimed.
