Can I renew my driver's license during the extension period?

Driver's licenses can be renewed within 1 to 3 years after expiration, but cannot be renewed after 3 years. Below are the relevant details: 1. Within one year of expiration: The driver's license can still normally process the 'expiration renewal' service, but driving motor vehicles on the road is not allowed during the overdue period. 2. One to three years after expiration: This situation falls under the 'recoverable cancellation' status. The driver can renew the license and restore driving eligibility after passing the subject one test again. 3. More than three years after expiration: In this case, the driver's license will be canceled, and the driver needs to retake subjects one, two, and three tests to restore driving eligibility.

Does a notch on the side of the tire have any impact?

A notch on the side of the tire does have an impact. If the sidewall of the tire is scratched, it is essential to replace the tire as soon as possible to avoid the risk of a high-speed blowout. If the damage to the contact surface exceeds 4mm, the tire must also be replaced promptly, as both internal and external repairs pose potential dangers. Here are some methods to extend the life of your tires: 1. Develop the habit of regularly checking tire pressure: Air pressure is crucial for extending tire life—if the pressure frequently exceeds the normal level by 20%, the tire's lifespan will decrease by 10%; if it is often 30% below normal, the lifespan will be reduced by 52%. 2. Maintain consistent tire pressure: Tire pressure is the lifeblood of the tire. If the pressure is too low, the tire body deformation increases, leading to cracks on the sidewall, excessive heat generation, rubber aging, fatigue of the cord layer, and cord breakage. 3. Regularly remove foreign objects from the tire: While driving, small stones often get lodged in the tread grooves. If not removed promptly, these stones can puncture the tire over time, causing air leaks or blowouts. 4. Adopt scientifically sound driving habits: When driving on roads with significant curvature, try to stay centered to avoid or reduce vehicle weight shifts, which can cause uneven tire wear due to increased load on one side. 5. Maintain accurate wheel alignment: Front-wheel alignment significantly affects tire lifespan, with toe-in and camber being the primary factors. Excessive camber accelerates shoulder wear and uneven wear, while improper toe-in mainly accelerates wear on the inner and outer edges of the tire.

Can someone else's driver's license be used for point deduction?

Driver's license point deduction cannot be done using someone else's license. Additional information: New regulations on driver's license point deduction: According to the "Guidance on Handling Traffic Violations Based on Technical Monitoring Records," if within one scoring cycle, the same driver handles violations for more than three different license plate vehicles not owned by themselves, it will trigger a suspicious driver's license investigation procedure. A single vehicle can only have violations handled by up to three different driver's licenses, and one driver's license can handle violations for up to three vehicles, thus restricting the practice of having others take the points. Point deduction process: Traffic police print out the official penalty notice on a computer or police terminal using the driver's license and vehicle registration. If the violation involves point deduction, the points will be recorded when the penalty notice is printed. The points will be deducted after the fine is paid.

Why does a car start and then stall?

Reasons why a car starts and then stalls: 1. Throttle failure: The throttle is blocked or severely carbon-deposited; 2. Issues with the ignition coil or spark plug: Excessive spark plug gap can cause the car to stall; 3. Fuel injector failure: Blocked fuel injectors lead to insufficient fuel supply and stalling. Problems in any part of the fuel system, ignition system, or intake system can cause this phenomenon. If the car stalls even when the air-fuel mixture enters the cylinder normally, it is highly likely that there is a fault in the ignition system. The role of the ignition system is to generate a sufficiently energetic spark between the electrodes of the spark plug in accordance with the working sequence of the cylinders.

Can I Still Get Points Deducted After Reducing Points Through Legal Study?

After reducing points through legal study, you can still get points deducted. It only reduces the penalty points on your driver's license and does not affect its use. Here is some information about reducing points through legal study: 1. Purpose: On the surface, reducing points through legal study gives the driver's license more behavioral points, but more importantly, it encourages drivers who have been penalized to participate in legal study. 2. Notes: If you accumulate 12 penalty points, your driver's license will be suspended, and you must attend a 7-day study session for Subject 1 at the location of the traffic violation within 15 days and pass the exam. Additionally, if you accumulate 12 penalty points in the current scoring cycle, you cannot participate in the point reduction activity in the next scoring cycle.

What is the appropriate lumen level for LED headlight bulbs in cars?

For car LED headlight bulbs, if halogen low beams are used, around 1000 lumens is appropriate, while 1200 lumens is suitable for high beams. If equipped with xenon lights, over 2000 lumens is recommended. Car headlights, also known as car front lights or LED daytime running lights, should be used properly during daily driving to ensure road safety. Unlike traditional halogen lamps, car xenon lights are high-pressure discharge lamps. Their illumination principle involves stimulating a chemical reaction between xenon gas and rare metals through positive and negative electrical charges, causing them to emit light. Therefore, the lamp contains a small glass bulb filled with xenon gas and a small amount of rare metals.
