How is the driving experience calculated when upgrading from C1 to B2 license?

C1 to B2 license upgrade requires holding a C1 driver's license for more than 1 year, so the driving experience at this time is the actual time of holding the C1 license. The examination process for upgrading from C1 to B2 driver's license is as follows: Upgrading from C1 to B2 requires retaking the exam starting from Subject 1. The contents of Subject 1, Subject 3, and Subject 4 remain unchanged, which are theoretical test, road test, and safe civilized driving test respectively. As for Subject 2, it includes stake test, hill start, parallel parking, single-plank bridge, curve driving, right-angle turn, narrow gate, continuous obstacles, bumpy road, narrow road U-turn, as well as simulated highway, continuous sharp mountain roads, tunnel, rain (fog) weather, slippery road, and emergency handling. C1 driver's license: C1 driver's license is one of the motor vehicle driver's license codes. The permitted driving scope of C1 license includes small and mini passenger vehicles, light and mini cargo vehicles; light, small, and mini special operation vehicles; small passenger vehicles with seating capacity ≤9 persons. Application age: The minimum age limit for C1 license is 18 years old, with no upper limit. However, applicants over 70 years old must pass tests on memory, judgment, and reaction abilities.

Can the transmission achieve the original effect after repair?

After repair, the transmission can generally achieve the original effect. Introduction to the transmission: The transmission is a device that changes the speed ratio and direction of motion. It is used in automobiles, tractors, ships, machine tools, and various machines to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. A gear-driven transmission generally consists of a housing and several pairs of gears. Maintenance of the transmission: Inspect the transmission promptly; regularly check the fluid level in the transmission to ensure it remains within the specified range, and top it up as needed based on actual working conditions. When topping up, ensure the new fluid is of the same type. When changing the fluid, do so while the transmission is operating, promptly draining the old fluid and cleaning the system. Regularly inspect the working condition of the transmission gears to ensure they mesh optimally, and clean them promptly to maintain proper fit between the gears and shafts. Regularly check the condition of various connection points in the transmission; during routine maintenance, inspect the state of all connection points in the transmission to promptly identify any issues such as looseness, wear, or damage. Tighten any loose connections immediately, and repair or replace damaged parts promptly. Regularly inspect the oil seals at the shaft ends and external joints for any oil leaks or seepage, and replace any failed seals or gaskets promptly.

Can You Make a U-Turn at an Intersection?

Whether a vehicle can make a U-turn at an intersection depends on the specific road conditions. Below are the situations where a U-turn is permitted at an intersection. Lanes with U-turn signs: When the U-turn signal light is green, you can make a U-turn while ensuring your own safety. Intersections without U-turn signs but allowing left turns: At intersections where left turns are permitted and there are no signs or markings prohibiting U-turns, you can also make a U-turn. However, the U-turn should not affect the normal flow of other vehicles, and you must follow the left-turn lane signal light. Yellow grid line areas: Although yellow grids are no-stopping zones, as long as there is no central barrier, you can make a U-turn after yielding to normally moving vehicles. Areas with dashed lines on the green belt: Vehicles on the side where the dashed lines are located can make a U-turn there. Note that U-turns in this situation are not controlled by traffic signals, but you must yield to vehicles moving straight. If making a U-turn does not require crossing the lane stop line, you do not need to consider the traffic light and can make a reasonable U-turn. However, if making a U-turn requires crossing the stop line of the left-turn or U-turn lane, you must observe the traffic light. Do not cross the stop line when the light is red.

What is the Problem with Rusty Brake Pads?

Rusty brake pads are a normal occurrence, primarily caused by the material of the brake pads, but this does not affect the safety or normal operation of the vehicle and does not cause any issues. If the rust on the brake disc is minimal, it does not require special treatment; if the rust is more severe, it may cause vibrations or shaking during braking, such as brake pad vibration, steering wheel shaking, or body vibration. In such cases, the brake pads need to be replaced. Most car brake pads are made of cast iron. Long-term exposure to rain, snow, and harsh environments inevitably leads to surface rust. If the rust is minor, it can be worn away through regular braking. Additionally, friction between the brake pads and the brake disc can also remove rust after several braking cycles, restoring normal use. If the brake pads are severely rusted, the surface becomes uneven, causing shaking, increased wear, or scratches, which can affect the vehicle's braking performance and driving safety. In such cases, it is best to take the vehicle to a repair shop. The brake disc should be removed, and the rust should be cleaned off with sandpaper. After proper installation, a road test should be conducted to ensure there are no abnormalities in braking. It is important to note that sanding should not be too forceful or done too frequently, as this can thin the brake disc, affecting its performance and lifespan.

What is the Difference Between Powder Coating and Baking Paint?

The differences between baking paint and powder coating include: powder coating has poorer gloss and roughness compared to baking paint; powder coating is generally thicker than baking paint; it offers better adhesion and corrosion resistance than baking paint; powder coating requires higher curing temperatures and typically uses electrostatic application, while baking paint generally requires lower temperatures; surface treatment for powder coating can be simpler, not requiring a primer, whereas baking paint needs a primer during application. Baking paint is an industrial paint, divided into two types: water-based metal paint and oil-based metal paint. Water-based metal paint is an environmentally friendly coating using water as a solvent, while oil-based metal paint uses organic solvents. The method involves roughening the material slightly and then applying some paint. Baking paint is non-sticky, making the coating less likely to adhere to other substances, while the film exhibits good bonding properties. Additionally, baking paint is heat-resistant and has low friction. It offers excellent wear resistance under high loads, combining the dual advantages of wear resistance and non-adhesion under certain loads. Baking paint is resistant to chemical erosion, protecting components from any kind of chemical corrosion. Powder coating does not require thinners, making the process environmentally friendly and non-toxic to humans. The coating appearance is excellent, with strong adhesion and mechanical strength. The spraying process is shorter, and the coating's wear resistance is significantly higher, not requiring a primer. Some construction sites explicitly require the use of electrostatic spraying, which avoids the common flow issues seen in conventional spraying processes.

What are the symptoms of a mismatched battery replacement in a BMW?

The symptoms of a mismatched battery replacement in a BMW are: hearing abnormal sounds from the audio system after turning off the engine, potential battery damage, and possible power leakage. The following are precautions for car battery replacement: 1. Battery selection: When purchasing a battery, ensure it matches the original battery model of your car to ensure proper functionality. It is recommended to use branded batteries for guaranteed quality. 2. Battery replacement: During battery replacement, maintain power connection by first connecting the new battery to the vehicle's power source. After removing the old battery, install the new one. After installation, drive for about half an hour to allow the battery to charge and ensure sufficient power.
