How Many Degrees to Turn the Steering Wheel for a Right Turn?

When making a right turn, the steering angle should be adjusted when the right front corner of the car is tangent to the roadside (i.e., forming a 180-degree angle between the right front corner and the roadside) if the turning path is narrow. For a left turn on a wide road, you can start turning slightly earlier: For a right turn on a narrow road, start turning when the left front corner of the car is tangent to the roadside; for a right turn on a wide road, you can start slightly earlier. Alternatively, you can observe the front corner of the car 'biting' the edge line—meaning the front corner continuously follows the roadside line. When the car can no longer 'bite' the line, start turning the steering wheel. The key is to 'bite'. Principles for turning the steering wheel: For gentle turns (turn early and slowly; return early and slowly). For sharp turns (turn late and quickly; return early and quickly). During turns, be careful not to scrape the right side or let the rear wheels leave the road surface, and pay attention to the inner wheel difference.

The Difference Between Foot Brake and Hand Brake in Automatic Transmission Cars

The difference between foot brake and hand brake in automatic transmission cars: The foot brake generally refers to the service brake, which distributes hydraulic pressure or air pressure from the master cylinder to the wheel brake cylinders, then pushes the brake pads to friction against the brake discs (or drums), thereby achieving deceleration or stopping. The hand brake, also called the parking brake, operates on a different principle. It uses a steel cable connected to the rear brake shoe assembly to apply braking force to the vehicle. Explanation of car foot brake and hand brake: 1. Hand brake position: The hand brake is typically designed near the gear lever on the right side of the driver's seat. Pulling up the lever engages the hand brake, while pressing the button on the hand brake lever and lowering the handle releases it. Foot brake cars are generally automatic transmission vehicles, with the foot brake pedal located where the clutch would be (slightly higher position). Some people mistakenly confuse it with the clutch pedal. To release the foot brake, simply press it down. 2. Return spring: The hand brake system includes a return spring. When the hand brake is engaged, the spring stretches; when released, it returns to its original length. With prolonged use, the spring may deform. Any component subjected to long-term, frequent use will experience reduced effectiveness. This doesn't mean "don't use it," but rather that components should be used normally according to their characteristics. The foot brake serves as an emergency braking system that applies braking force directly to the wheels.

What is the function of the button on the automatic transmission gear shift?

The button on the automatic transmission gear shift is a gear lock. Without pressing this button, you cannot freely change gears, which serves to prevent accidental gear shifting. Below are the relevant details: Related functions: The purpose of the gear lock is to ensure driving safety by preventing accidental engagement into other gears. After starting the engine, when moving the gear shift lever out of the "P" (Park) position, you need to press the foot brake pedal and press the shift button. Similarly, when shifting from "R" (Reverse) to "P," the shift button must also be pressed. Gear arrangement: Automatic transmission gear shifts commonly come in two layouts: straight-line and zigzag. Straight-line automatic transmissions are prone to accidental gear changes due to easy misoperation, hence the inclusion of a lock button. On the other hand, zigzag automatic transmissions inherently have a limiting function that prevents misoperation, so they do not require a lock button. Special cases: The button on the automatic transmission gear shift may include a shift lock button and a sport mode button. Depending on the vehicle design, some models may not have a sport mode button on the gear lever. To use manual shifting mode, move the gear shift lever from the "D" (Drive) position to the manual shift slot, and the transmission will enter manual shift mode. Alternatively, you can manually select gears using the paddle shifters on either side of the steering wheel.

What Causes Intermittent Air Conditioning Failure in Cars?

Here are the specific reasons why a car's air conditioning intermittently fails to cool: 1. Insufficient refrigerant: Car refrigerant typically needs replenishment every 2-3 years. If the interval is shorter, it indicates a refrigerant leak. The car's air conditioning system consists of multiple metal pipes with tiny gaps between them, leading to minor refrigerant leakage. Additionally, the system's dryer bottle absorbs moisture, which compresses some refrigerant. When the refrigerant level drops below a certain point, the air conditioning's cooling capacity diminishes. 2. Dirty condenser: During summer, poor air conditioning performance may occur even when the system tests normal with standard high and low pressure readings. Dealerships often recommend cleaning the radiator and condenser, primarily to improve heat dissipation. Accumulation of springtime poplar and willow catkins on the condenser can cause engine overheating or poor air conditioning performance. 3. Lack of maintenance: The filter is a crucial component of the car's air conditioning system. Frequent driving in dusty areas causes the filter to block external dust from entering the cabin. Over time, the filter becomes dirty, develops odors, or even clogs. When the filter is clogged with dust and debris, it severely reduces the air conditioning's airflow, resulting in weak cooling performance. 4. Worn or loose belt: After checking all air conditioning components with no apparent issues, the belt might be the overlooked culprit. Dealerships usually recommend belt replacement during maintenance. Failure to replace it can lead to slipping, which may cause belt breakage, unusual noises, loss of power assistance, or poor air conditioning performance. Therefore, inspecting the engine belt is also essential.

How to Handle 12 Points Deducted from the Driver's License?

Here is an introduction about what happens when 12 points are deducted from a driver's license: 1. For Class AB licenses with 12 points deducted: The highest permitted driving category will be revoked, and the driver must complete the downgrade and license replacement procedure within 30 days. The driver's license will be temporarily confiscated, and the driver must attend a 7-day training course at the license issuing location or the place where the violation occurred within 15 days. After completing the course, the driver must take an exam. If passed, the points will be cleared, and the driver's license will be returned. If failed, the driver must continue training and retake the exam. Refusal to attend training or take the exam will result in the public announcement by the traffic management department of the public security authority that the driver's license is suspended. 2. For Class C licenses with 12 points deducted: If 12 points are deducted within one scoring cycle, the driver's license will be temporarily confiscated, and the driver must retake the subject one exam. If passed, the points will be cleared, and the driver's license will be returned. If failed, the driver must continue training and retake the exam. Refusal to attend training or take the exam will result in the public announcement by the traffic management department of the public security authority that the driver's license is suspended. 3. For probationary periods with 12 points deducted: For Class AB license holders, 12 points deducted during the probationary period will result in immediate revocation and downgrade. For Class C license holders, 12 points deducted during the probationary period will result in the revocation of the driver's license.

How to Register After Failing the Driving Test Five Times?

According to relevant regulations, for the driving license test, the number of scheduled attempts for the Road Test (Subject Two) and the Road Driving Skills Test (Subject Three) must not exceed five. If the fifth scheduled test is still failed, the results of other subjects that have been passed will be invalidated. The individual must then re-register and pay for the Subject One test again. The passing scores for the driving license test are as follows: 1. Subject One (Traffic Regulations and Related Knowledge): Written test, with a full score of 100, 90 or above is required to pass (including 90). 2. Subject Two (Field Driving): Conducted on-site with an actual vehicle. Results are only categorized as pass or fail. The test includes five mandatory items conducted in sequence: reversing into a parking space, parallel parking, S-curve driving, right-angle turning, and hill start and stop. The full score is 100, with 80 or above required to pass (including 80). For large buses, medium buses, and large trucks, 90 or above is required to pass (including 90). 3. Subject Three (Road Driving): Conducted on actual roads or simulated environments with an actual vehicle. The full score is 100, with 90 or above required to pass (including 90). 4. Subject Four (Safe and Civilized Driving Related Knowledge): Written test, with a full score of 100, 90 or above is required to pass (including 90).
