What to Pay Attention to When Applying for Driving School

Here are the things to pay attention to when applying for driving school: 1. Whether the driving school has its own regular training ground and where it is located (avoid signing up with Driving School A but practicing at Driving School B), and whether it is a private car owner affiliated with the driving school; 2. The reputation of the driving school, its pass rate, and the integrity of the instructors—these will directly affect how much you will spend on driving lessons; 3. Whether the driving school charges a one-time fee. Legitimate driving schools usually charge slightly higher fees, while some schools attract students with low prices but charge various additional fees during training, ultimately costing you thousands more than schools with higher initial fees; 4. When signing up, be sure to visit the training ground. Legitimate driving schools may even offer free trial lessons; 5. Whether additional fees are charged for using the training ground or for retaking lessons if you fail the test; 6. Whether the fee details are clearly stated in the contract and whether the contract uses the standardized numbered version issued by the transportation authority. Some branch schools use simplified contracts printed on A4 paper, and some privately affiliated schools may not even sign contracts, leaving students' rights unprotected.

What Causes Heavy Steering Wheel Feel?

Here are the reasons why the steering wheel feels heavy: 1. Insufficient power steering fluid/oil. Power steering fluid is a medium oil used in the car's power steering pump, which transmits steering force and provides cushioning. The power steering fluid needs to be replaced regularly, and checked for leaks. When the power steering fluid is insufficient, the steering will feel heavy and stiff. 2. Low tire pressure. Low tire pressure increases the contact area between the tires and the road surface, leading to greater friction and making steering more difficult, resulting in a heavy steering wheel, which is not conducive to driving safety. 3. Steering gear or power steering pump failure. The steering gear and power steering pump also affect the car's steering. Any malfunction in these two critical components can cause steering difficulties.

What to Do If Your Vehicle License Plate is Cloned?

Here are the steps to take if your vehicle license plate is cloned: 1. Gather evidence that the vehicle owner was not present at the scene. 2. Visit the traffic police department to verify the violation information. 3. Submit an appeal to the traffic management department. 4. Apply for a replacement of the vehicle license plate number. Here are the legal bases: 1. If the motor vehicle license plate or registration certificate is lost, missing, or damaged, the vehicle owner must apply for a replacement or reissuance at the local vehicle management office. When applying, the vehicle owner must fill out an application form and submit proof of identity. 2. The vehicle management office shall review the submitted proofs and documents, retrieve the license plate or registration certificate that is not lost, missing, or damaged, reissue or replace the registration certificate within one day from the date of acceptance, and reissue or replace the license plate within fifteen days from the date of acceptance, with the original license plate number remaining unchanged. During the period of reissuance or replacement of the license plate, a temporary license plate valid for no more than fifteen days shall be issued.

How Many Years Should Tires Generally Be Used Before Replacement?

Automobile tires can generally be used for 3-5 years, with a recommended mileage not exceeding 60,000 kilometers. The service life of car tires is directly related to the driver's driving habits and the driving environment. During daily vehicle use, it is necessary to make reasonable judgments about the tires. If the tires are no longer usable, they should be replaced promptly. The following are indicators for tire replacement: 1. Sidewall bulging: If bulging appears on the sidewall of a car tire, it is necessary to replace the tire immediately. Sidewall bulging is difficult to repair and indicates that the tire's cords have broken. This can lead to a blowout at any time while driving, so timely replacement is essential to avoid compromising driving safety. 2. Tire cracks: Tire cracks are relatively common during daily vehicle use. These cracks can vary in length and depth, requiring careful assessment. If the condition of the tire cannot be determined, it is recommended that the owner visit a 4S shop or a professional auto repair shop for inspection. Severe tire cracks can lead to bulging and eventually cause a blowout. 3. Tire wear indicators: Car tires have wear indicators, which mark the limit of tire wear. If the tire wear reaches this indicator, the tire should be replaced immediately. Such tires pose significant safety hazards. Even on dry roads, the braking distance will increase, and on wet or slippery roads, they are prone to skidding or brake failure.

Should Snow on the Car Be Cleaned?

Snow on the car should be cleaned. Accumulated snow on the car's surface not only affects the vehicle's appearance but also contains corrosive substances. If not dealt with promptly, it can corrode the car's paint, shortening its lifespan. Therefore, it is necessary to clean it in time to avoid affecting normal driving. Here are some related tips for dealing with snow on the car: 1. Do not forcibly activate the windshield wipers: When there is snow on the car's surface, avoid using the windshield wipers hastily. The wipers, covered in ice and snow, may freeze and stick to the windshield. Forcibly turning them on can damage the wiper motor or tear the rubber surface of the wipers, leading to unnecessary replacement costs. 2. Cleaning snow without an ice layer: For snow on the car's surface without an ice layer, the cleaning process is relatively simple. Use a soft cloth or a gentle tool to gently sweep the snow in one direction. Since the snow hasn't melted, it causes minimal damage to the car's paint. 3. Cleaning snow with an ice layer: During daily driving, snow on the car's surface usually comes with an ice layer. To clean this type of snow, first use a specialized car snow shovel to remove the snow.

Why can't the compression ratio be increased too high?

Increasing the compression ratio too high can easily cause knocking. A high compression ratio is one of the factors that lead to knocking. For engines of the same displacement, a higher compression ratio results in better power and fuel economy. However, there are limits to everything. Simply increasing the compression ratio to pursue high performance while ensuring normal operation presents exponentially increasing difficulties. Below is an introduction to compression ratio: 1. The compression ratio is a parameter that can basically reflect the efficiency of an engine. For naturally aspirated engines, without considering other factors, an increase in the compression ratio means that the engine's performance and efficiency are also improved accordingly. 2. However, the compression ratio cannot be increased too high because it can cause knocking in gasoline engines. This phenomenon can severely affect the working life of gasoline engines, so it is often necessary to use higher-octane gasoline to reduce the likelihood of knocking.
