What is the difference between b1 and b2?

1 Answers

b1 and b2 differ in the types of vehicles they permit driving: the b1 license allows driving medium-sized buses (c1 and m, where m stands for wheeled self-propelled machinery), including city buses with a capacity of 10 to 19 passengers; the b2 license permits driving large trucks, c1, and m, enabling the holder to operate heavy, medium-sized trucks, and large, heavy, or medium-sized specialized operation vehicles. A driver's license is a document issued by the government transportation department to individuals qualified to drive, typically in the form of a card. To obtain a driver's license, one must meet the minimum age requirement and pass a driving test. The license usually specifies the types of motor vehicles the holder is permitted to drive, such as motorcycles, passenger cars, trucks, and buses.

Can Guowu Vehicles Still Be Licensed in Baoding?

Baoding officially implemented the China VI emission standards from July 1, 2019. After July 1, models that do not meet the China VI emission standards will be prohibited from being sold, registered, or transferred in. Owners of China V emission standard vehicles purchased before July 1 can complete registration and transfer procedures at the local vehicle management office before October 1 with valid certificates. Here is additional information: 1. China VI Standard: The China VI standard, also known as the 'National Sixth Stage Emission Standards for Motor Vehicles,' includes 'Limits and Measurement Methods for Emissions from Light-Duty Vehicles (China VI)' and 'Limits and Measurement Methods for Emissions from Heavy-Duty Diesel Vehicles (China VI).' Compared to China VI A, China VI B imposes stricter requirements on the emissions of carbon monoxide, non-methane hydrocarbons, nitrogen oxides, and PM fine particulate matter, with significantly tighter limits. China VI A can be considered a transitional phase to China VI B. 2. Continuous Updates to Emission Standards: To alleviate environmental pressure, China's vehicle emission standards have been continuously updated. The China V standard was officially implemented in 2017, and the country will enter the era of China VI in 2020. The 'China VI Standard' for light-duty vehicles is being implemented in stages, with two emission limit schemes—China VI A and China VI B—set to be implemented in 2020 and 2023, respectively.

How to Open a Truck When the Keys Are Locked Inside?

Here are solutions for when truck keys are locked inside: 1. Contact a professional locksmith: Always choose a company with proper qualifications. Generally, whether it's for home security doors or vehicle locks, legitimate companies require registration with local police stations. Some companies may only need your ID card, driver's license, and vehicle registration to verify your information before assisting with unlocking. 2. Use the spare key to unlock the vehicle: This method is only feasible if you're close to home. Typically, when purchasing a vehicle, you receive two keys, sometimes three. Therefore, when your primary key is locked inside, you can use the spare key for access. 3. Break a window to gain entry: If breaking a window is necessary, choose a side window rather than the windshield or triangular windows. Side windows have lower replacement costs and are easier to match during repairs.

What are the effects of changing from 185 tires to 195?

The effects of changing from 185 tires to 195 are: 1. Increased driving friction: The increased friction makes the steering wheel heavier during driving, and tire noise and fuel consumption also increase; 2. Increased turning radius: It interferes with the geometric dimensions of the car body, suspension, and other designs, significantly increasing the turning radius. This can make the car more prone to tipping over during sharp turns, as the centrifugal force from the car's side tilt can lift the inner wheels off the ground. Additional information: 1. Benefits of wider tires: Wider tires improve the car's stability at high speeds. Additionally, reducing the tire's aspect ratio provides better handling and a more comfortable road feel. 2. Impact of wider tires on fuel consumption: As the tires widen, the car's fuel consumption will increase accordingly. Generally, it is not recommended to change the tire size from the original factory specifications, as any changes in tread width, aspect ratio, or diameter can cause errors in the car's ESP, odometer, and speedometer, potentially compromising driving safety.
