Is Subject 4 a Written Test?

Subject 4 is a written test. Subject 4 is one of the driver's license tests, which are conducted to obtain a motor vehicle driving license. The driving test consists of four parts: Subject 1, Subject 2, Subject 3, and Subject 4, covering traffic regulations and related knowledge, field driving skills, road driving skills, and safe and civilized driving knowledge, respectively. Subject 4 is also known as the Subject 4 theoretical test or the driver's theoretical test, and it is part of the motor vehicle driving license assessment. Test Content: After the implementation of the Ministry of Public Security's Order No. 123, Subject 3 was divided into two parts. In addition to the road test, a safety and common sense test was added. Since this test is conducted after Subject 3, it is commonly referred to as Subject 4, although officially, there is no Subject 4. The test consists of 50 questions, primarily in the form of case studies, images, and animations, with a full score of 100 and a passing score of 90. Notes: Both Subject 1 and Subject 4 are theoretical tests, and passing them requires extensive reading and memorization. Subject 4 mainly tests the requirements for safe and civilized driving operations, as well as knowledge of safe driving under adverse weather and complex road conditions. During the test, there will be a camera on the desk or computer, and you can monitor the screen display. Maintain discipline during the test; do not look around or attempt to cheat. Each examinee's questions are randomly selected by the computer from the question bank, and the questions for people around you will be different. Do not attempt any so-called high-tech cheating methods, as they are easily detected, and if caught, you will be barred from applying for the driver's test for one year.

Does the Car Accelerator Cause Damage to the Vehicle?

Car accelerators do not cause harm to the vehicle because they are not active signal devices but rather passive devices that receive and relay signals, functioning like a physical adapter without disrupting any of the original car's wiring. Below is relevant information: Electronic throttle accelerators: 1. "Acceleration": Primarily achieved by increasing throttle response sensitivity, it amplifies the input throttle signal by 50%. When the driver presses the pedal 66%, the accelerator's output is already at full throttle, thereby improving throttle response sensitivity by 50%. 2. How the accelerator works: When the throttle pedal is pressed, the accelerator calculates the rate of change of the throttle signal based on the degree and duration of the press. The faster the change, the stronger the acceleration demand, and the throttle accelerator will amplify this rate of change, ultimately resulting in better dynamic response during acceleration.

What Causes the Transmission Maintenance Alert in the Buick LaCrosse?

LaCrosse cars display a transmission maintenance alert because there is a malfunction in the vehicle's transmission system. It is necessary to promptly visit a 4S dealership or a professional transmission repair center for inspection. The issue can be analyzed by reading the fault codes via computer diagnostics. The LaCrosse is a new mid-to-high-end sedan model launched by Shanghai General Motors in 2006, featuring a chassis configuration tailored to China's basic road conditions. The LaCrosse is equipped with three engine options: 2.0T, 2.4T, and 3.0T. The market price of the vehicle ranges from 209,800 yuan to 329,800 yuan. Taking the LaCrosse 2021 552T Luxury model as an example, its body dimensions are: length 5026mm, width 1866mm, height 1459mm, wheelbase 2905mm, and curb weight 1535kg. The LaCrosse 2021 552T Luxury model features a MacPherson strut front suspension and a multi-link independent rear suspension. It is powered by a 1.5T turbocharged engine with a maximum torque of 250Nm and a maximum power output of 124kW. Summary of common transmission issues in the LaCrosse: The LaCrosse transmission may experience no reverse gear, jerking when shifting to D gear, severe jerking when shifting to reverse gear, or no forward gear. Other issues include transmission fluid leaks, slow acceleration, occasional absence of 6th gear (gradually becoming more frequent), and delayed gear engagement. Solutions for common transmission issues in the LaCrosse: Repair the transmission control module or mechanical components, and replace worn parts to resolve the problems.

Can I transfer my driving test to another location?

You can transfer your driving test to another location. 1. If the applicant has passed Subject 1, Subject 2, or Subject 3 in the original test location: The applicant should personally apply to the vehicle management office in their current residence to change the test location and continue taking the remaining subjects. 2. If the applicant has registered but not yet passed Subject 1 in the original test location: They can re-register for the test in their current residence. The original registration information will be automatically canceled, and they can still apply to change the test location once after re-registering. 3. After the application is accepted: The applicant should schedule the test through the internet service platform. The total number of attempts for Subject 2 and Subject 3 road driving skills tests should not exceed five times each in both the original and new test locations. 4. After the applicant passes all subjects: The vehicle management office in the new test location will issue the license and archive the records.

What are the consequences of insufficient brake fluid in a car?

Insufficient brake fluid can affect braking performance, potentially leading to a complete loss of braking function. Below is relevant information: Brake fluid: Also known as hydraulic brake fluid, it is an essential component of the braking system. Frequent braking during driving generates significant frictional heat, raising the temperature of the braking system. If low-boiling-point or easily evaporable brake fluid is used, it may vaporize at high temperatures, filling sections of the brake system's pipelines with vapor and causing vapor lock, which results in brake failure. Precautions for insufficient brake fluid: 1. If gasoline, diesel oil, or windshield washer fluid accidentally mixes with brake fluid, it can severely impair braking performance. Immediate replacement is necessary. 2. Under normal driving conditions, brake fluid should be replaced every 40,000 kilometers or every 2 years of continuous use, as prolonged use can cause deterioration. 3. For vehicles equipped with a brake fluid level warning system, regularly check whether the warning light is flashing and ensure the sensor is functioning properly. When brake fluid is low, it should be replenished promptly. Stored brake fluid should always be maintained between the marked minimum and maximum capacity levels.

How to Operate on Wet Roads in Subject 2?

When driving on slippery roads in Subject 2, you should follow the tire tracks of the vehicle ahead to avoid sliding off the road. If you notice the rear wheels skidding during braking, immediately release the brake and use a 'press-release' method (i.e., pumping the brakes), while gently steering in the same direction as the skid to regain control. Precautions: During driving: Maintain a steady speed in third gear and avoid sudden braking to prevent the vehicle from skidding into roadside ditches. If rear-wheel skidding occurs: If you notice the rear wheels skidding during braking, immediately release the brake and use a 'press-release' method (i.e., pumping the brakes), while gently steering in the same direction as the skid to regain control. For front-wheel skidding, steer gently in the opposite direction of the skid. Maintain a steady speed in third gear and avoid sudden braking to prevent the vehicle from skidding into roadside ditches. After starting, apply throttle smoothly and avoid high RPMs or excessive throttle. Due to low tire grip on slippery roads, high RPMs and excessive throttle can cause wheel spin and difficulty in starting. When starting: Apply throttle smoothly and avoid high RPMs or excessive throttle. Due to low tire grip on slippery roads, high RPMs and excessive throttle can cause wheel spin and difficulty in starting. Details: The test content for Subject 2 varies by vehicle type, as follows: Basic test items: Pole test, hill start and stop, parallel parking, single-plank bridge, curve driving, right-angle turn, speed-limited passage through narrow gates, continuous obstacle passage, 100-meter gear shifting, and bumpy road driving. For large buses, tractors, city buses, medium-sized buses, and large trucks, the test must include no fewer than 6 items.
