Can You Get a Driver's License with One Eye Blind?

If one eye is blind but the other eye is normal, you can obtain certain driver's licenses below the C1 category. Here is additional information: 1. To apply for large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, large trucks, trolleybuses, or tram driving licenses, the naked or corrected vision of both eyes must reach 5.0 or above on the logarithmic visual acuity chart. 2. For other driving license categories, the naked or corrected vision of both eyes must reach 4.9 or above on the logarithmic visual acuity chart. 3. For individuals with monocular vision impairment, if the better eye's naked or corrected vision reaches 5.0 or above on the logarithmic visual acuity chart and the horizontal field of vision reaches 150 degrees, they can apply for a driver's license for small cars, small automatic transmission cars, low-speed trucks, three-wheeled cars, or small automatic transmission passenger vehicles for the disabled. 4. People with red-green color blindness cannot apply for any driver's license.

Can people with myopia get a driver's license?

According to the regulations on the application and use of motor vehicle driver's licenses, people with myopia can obtain a driver's license. 1. For applicants applying for large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, large trucks, trolleybuses, or tram driving models, the naked-eye vision or corrected vision of both eyes must reach 5.0 or above on the logarithmic visual acuity chart. For applicants applying for other driving models, the naked-eye vision or corrected vision of both eyes must reach 4.9 or above on the logarithmic visual acuity chart. 2. High myopia refers to myopia above 600 degrees, and people with myopia above 800 degrees are advised not to drive. Eye diseases such as glaucoma and cataracts disqualify individuals from obtaining a driver's license.

What to Do When the Car's Three-Way Catalytic Converter Glows Red?

If the car's three-way catalytic converter malfunctions, it should be taken to a 4S shop for inspection and repair. The following explains the reasons why a car's three-way catalytic converter may glow red: 1. Exhaust system blockage: This prevents the engine's exhaust gases from smoothly exiting after passing through the three-way catalytic converter, leading to poor heat dissipation and causing the ceramic core inside the catalytic converter to turn red under high temperatures. 2. Broken ceramic liner inside the three-way catalytic converter: This prevents exhaust gases from passing through smoothly, generating high temperatures. If the front intake part of the catalytic converter is red while the rear exhaust part is normal, the issue lies with the catalytic converter itself. Otherwise, the problem is with the exhaust pipe.

What Items Are Included in a Car's Fourth Maintenance?

Car's fourth maintenance primarily involves replacing the oil filter and gear oil, cleaning the air filter and cabin air filter, followed by various inspections. In addition to routine maintenance and oil changes, it includes replacing spark plugs. It is particularly advisable to replace the original spark plugs after 20,000 kilometers. For vehicles used for less than two years, it is necessary to top up the antifreeze and check the brake fluid. For vehicles that have been in use for two years, it is recommended to replace both the antifreeze and brake fluid. Additional Information: Many items in the regular maintenance schedule are not prone to damage under normal driving conditions, so they only require inspection. These include: tire side slip condition, brake function and pedal free play, hand brake function, clutch free play and clutch fluid level, steering wheel free play, air conditioning system, instrument functions, seat belts and warning systems, power windows, sunroof, rearview mirrors, lights, wipers, horn, antenna, central locking system, battery fluid, air conditioning compressor belt, distributor cap and rotor, high-voltage wires, ignition timing, idle speed and exhaust emissions, power steering system, fuel lines, driveshaft dust boots, exhaust muffler, suspension fastening nuts (chassis inspection), tires and rims, wheel bearings, front brake caliper oil pipes, secondary air injection system, positive crankcase ventilation system, evaporative emission control system, intake air temperature control system, catalytic converter, and oxygen sensors, among others. These components will only be replaced or adjusted by the maintenance facility if they are found to be damaged (abnormal) during the inspection.

How Often Should the Clutch Disc of an Automatic Transmission Car Be Replaced?

Automatic transmission clutch discs generally do not need replacement. There are several types of automatic transmissions: AT, CVT, AMT, and DCT. Among them, AT and CVT do not have clutch discs, while AMT and DCT do. As long as the vehicle is used normally and maintained regularly (checking and replacing transmission fluid), theoretically, the clutch disc of an automatic transmission does not need to be replaced throughout the vehicle's lifespan. Here is more information about automatic transmission cars: 1. An automatic transmission does not require the driver to manually shift gears; the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. Typically, automatic transmission cars have six gear positions, arranged from top to bottom as: P, R, N, D, S, and L. 2. Automatic transmission cars usually use a hydraulic transmission device to replace the mechanical clutch of manual transmission cars, so there is no clutch pedal. When the engine speed is low, the torque transmitted by the fluid is limited and insufficient to propel the car forward. When the gear lever is placed in the drive position and the brake pedal is released, as the accelerator is pressed and the engine speed increases, the transmitted torque increases, pushing the car forward. 3. The greatest advantage of automatic transmission cars is convenience, especially in heavy traffic.

What is the purpose of the 1, 2, 3 gears in an automatic transmission?

The 1, 2, 3 gears in an automatic transmission represent the low gear modes of the transmission. When shifted into 3, the transmission will only switch between gears 1, 2, and 3; when shifted into 2, the transmission will only switch between gears 1 and 2; when shifted into 1, the transmission will remain in 1st gear. More details are as follows: 1. The most common scenario for using these gears is when driving uphill or downhill. The steeper the slope, the lower the gear should be. Additionally, these gears can be useful during rainy days, icy or snowy road conditions, and in heavy traffic. 2. When climbing a long, steep slope, if left in D (Drive) mode, the transmission will continuously shift up and down, which can cause significant wear and tear on the transmission. In such cases, shifting to 2nd gear ensures the transmission only shifts between 1st and 2nd gears, minimizing unnecessary gear changes. 3. When descending a long, steep slope, if left in D mode, the driver would need to constantly use the brakes to control speed. Prolonged and frequent use of the brakes can lead to overheating, reduced braking efficiency, and a significant reduction in brake pad lifespan. In this situation, engine braking (using lower gears) supplemented by occasional braking is recommended. This principle is similar to downshifting in a manual transmission when going downhill.
