To apply for upgrading to a B1 license, you must hold a C1 license for at least one year. As a veteran driver with twenty years of experience, I understand this requirement is mainly to help you accumulate experience driving small vehicles on the road. You must be at least 18 years old and in good health, with a medical examination at a designated hospital confirming good vision, normal hearing, and no high blood pressure issues. The examination part is crucial: the theory test covers traffic rules, which are more complex than the C1 test and include passenger requirements for medium-sized buses; the practical test requires familiarity with handling larger vehicles, such as gear shifting and turning habits. Ensure your driving record is clean—no DUI or serious traffic violations—otherwise, you won’t pass the review. Don’t rush into the test; first, gain stability with your C1 license. Safety always comes first, and driving a bus carries great responsibility!

I just completed my additional driver's license and want to share my experience. For the C1 upgrade, you need to have held the license for at least one year and be over 18 years old - it's not too difficult. The medical check is crucial, as your vision must meet the standard; otherwise, driving medium-sized vehicles could be dangerous. The test consists of a written exam and a road test. For the written part, focus on memorizing bus safety knowledge. For the road test, I practiced turning and braking multiple times at the driving school to get used to the greater inertia. I recommend reviewing theoretical knowledge in advance and bringing your ID card and original driver's license when registering at the DMV. The whole process takes about two months to complete, and spending some money on a training course makes it easier to pass. Don't underestimate these requirements - they're all designed to prevent new drivers from losing control after impulsive upgrades.

What to do if the automatic transmission is stuck in P gear?

Solutions for automatic transmission stuck in P gear: 1. If the car has a shift lock gear lock, press the switch; 2. If there is no gear lock or the button does not work, you can pry open the shift dust cover, find the emergency switch of the shift mechanism, and press the switch. The correct method for parking and shifting gears: 1. Shift into N gear before parking; 2. Tighten the handbrake and then release the pedal; 3. After the car stops completely, shift into P gear. This way, the car will not slide forward or backward due to its own weight, avoiding the situation of the gear getting stuck when parking. Automatic transmission means that the driver does not need to manually shift gears. The vehicle will automatically select the appropriate gear to drive based on the speed and traffic conditions.

What is the function of the button on an automatic transmission?

The function of the button on an automatic transmission: The button on an automatic transmission is called the shift lock button, also known as the gear lock. If the gear is accidentally engaged, unintended forward or backward movement could cause an accident. This button can eliminate safety hazards caused by misoperation. When shifting out of P (Park) or into R (Reverse) or P (Park), this shift lock button must be pressed to engage the gear. Introduction to automatic transmission gears: 1. P stands for Park; after the car stops, engaging P gear applies the brake to prevent movement. 2. N stands for Neutral; temporarily stopping the vehicle by engaging this gear stops the vehicle's motion without interrupting power. 3. R stands for Reverse; this gear can only be engaged when the vehicle is stationary. 4. S stands for Sport, suitable for overtaking and climbing hills.

What does intermittent braking mean?

The meaning of intermittent braking is: first press the brake slightly, then release the brake (but not completely) when you feel the car decelerating significantly, and press the brake again when you feel the braking effect is about to disappear. Repeat this cycle. The applicable objects of intermittent braking: mostly used for large vehicles without ABS and with air brakes in the past, but the intermittent braking method will affect the smoothness and comfort of the vehicle. Small cars are lightweight, and if intermittent braking is not used for long downhill slopes, the wheel hubs will not overheat. It is not recommended to use intermittent braking for small cars to decelerate. The reason for using intermittent braking: because large vehicles are heavier, but air brakes respond faster than hydraulic brakes. To avoid locking the wheels and preventing the inability to steer, intermittent braking technique is adopted. The function of intermittent braking is: to prevent wheel lock-up, thereby controlling the vehicle from skidding.
