Will the driving school help if I fail the subject 2 test four times and take it five times?

If you fail the subject 2 test four times and take it five times, the driving school will not help. More relevant information is as follows: 1. "Regulations on the Application and Use of Motor Vehicle Driving Licenses" in Article 44: During the validity period of the study driving certificate, the number of appointments for the subject 2 and subject 3 road driving skills tests shall not exceed five times. If the fifth test appointment is still not passed, the results of other subjects that have been passed will be invalidated, and you will need to re-register and re-schedule the test. 2. Appointment: For any subject, each test appointment includes: one normal test opportunity and one immediate re-test opportunity. If you fail to pass after five consecutive test appointments (including the re-test opportunities, totaling 10 tests), the previously passed subject results will be invalidated, and you will need to start learning and testing again from subject 1.

Is driving at 130 km/h on a highway with a 120 km/h speed limit considered a traffic violation?

Driving at 130 km/h on a highway with a 120 km/h speed limit is considered a traffic violation, but if the speeding is within 10%, only a warning will be issued without penalty. Penalties for speeding on highways: If the speeding exceeds the limit by less than 10%, no penalty will be imposed; if the speeding exceeds the limit by 10% to 20%, a fine will be issued with 3 demerit points; if the speeding exceeds the limit by 20% to 50%, a fine will be issued with 6 demerit points; if the speeding exceeds the limit by more than 50%, a fine will be issued with 12 demerit points. Dangers of speeding: Higher speeds inherently mean that the vehicle has stronger inertia to maintain straight-line driving, resulting in poorer directional control and greater risks. In case of an emergency ahead, it is difficult for the driver to control the vehicle's speed and direction within a short time. Speeding increases the difference in airflow speed between the top and bottom of the vehicle body, thereby weakening the adhesion performance between the tires and the road surface and reducing the stability of the vehicle.

What Causes the Car to Shake When Shifting to D Gear?

It is normal for an automatic transmission car to experience slight shaking when shifting to D gear, especially for vehicles equipped with a torque converter in the AT transmission. This phenomenon is more noticeable because, in neutral, the engine's power is transmitted to the transmission input shaft through the torque converter. When shifting gears, the transmission engages while the input shaft is still rotating, resulting in an impact. However, some automatic transmissions use multi-plate clutches or dry clutches to transfer power between the engine and transmission. In these cases, the clutch is completely disengaged during gear shifts, eliminating the impact force and making the shaking less noticeable. Here is more information about car shaking when shifting to D gear: 1. Generally, during normal use, the body shaking when shifting from N to D gear is not very noticeable. Significant shaking is usually caused by the following situations: ① The engine speed is too high. For example, when the engine speed is high during a cold start, the torque converter transmits more power, resulting in a stronger impact and more noticeable shaking when shifting gears. ② The brake is not pressed firmly. When shifting gears, the engine power is directly transmitted to the wheels. If the brake is not pressed firmly, the wheels may move slightly when shifting to D gear, causing the car to jerk forward and creating a stronger shaking sensation. ③ The brake is released too early. This is most common when waiting at a traffic light. After the light turns green, the driver shifts gears and releases the brake to start moving, but the car suddenly jerks forward when the brake is released. This happens because releasing the brake too early causes an abrupt power engagement. The automatic transmission gear lever does not directly control the gear position; it is merely a signal device. Different gear positions generate different signals for the transmission control system, which then controls the gear shift. However, the transmission takes some time to complete the shift. Therefore, when shifting to D gear, the transmission gears are not yet engaged. By the time the brake is released, the gears have engaged, and the sudden power delivery to the drive wheels without the braking restriction causes the car to jerk forward. 2. Avoiding body shaking when shifting to D gear is simple: shift gears when the engine speed is stable, press the brake firmly when shifting, and release the brake only after feeling the power being transmitted to the wheels. Following these steps will significantly reduce noticeable shaking during gear shifts.

What is the engine model of the BMW 1M?

The N54B30 twin-turbocharged engine is the engine model used in the BMW 1M, with a maximum horsepower of 340 hp, a maximum power output of 250 KW, a maximum power speed of 5900 rpm, and a peak torque of 450 N.m. The new BMW 1M 1 Series is equipped with three displacement turbocharged engines, namely 1.6T, 2.0T, and 3.0T engines, all manufactured in Germany. For the daily maintenance of the BMW 1M's engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, causing various problems for the engine. To avoid failures, oil should be changed regularly according to usage conditions, and the oil level should be kept moderate. When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve, bringing dirt back to the lubrication area, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from part wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, blocking filters and oil holes, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall lifespan of the radiator and engine.
