What is the maximum speed when driving a motor vehicle through narrow roads or narrow bridges?

When driving a motor vehicle through narrow roads or narrow bridges, the maximum speed is 30 km/h. Here are some precautions to take when passing through narrow roads or bridges: 1. Speed: When encountering a narrow lane ahead, slow down in advance and increase the distance from other vehicles to avoid collisions. 2. Try to straighten the vehicle body: If the vehicle enters at an angle, it will undoubtedly increase the chance of scraping and reduce the available width for passage. 3. Turning: Always ensure the rear wheels have passed before turning, otherwise turning immediately after the front wheels pass an obstacle can easily lead to scraping when navigating narrow passages.

Can I directly schedule the Subject Two test after passing Subject One?

You cannot directly schedule the Subject Two test after passing Subject One. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the waiting period between Subject One and Subject Two varies depending on the type of license. For a C-class license, you must wait 10 days after passing Subject One, while for A and B-class licenses, you must wait 20 days before scheduling. This provides ample time to prepare for the Subject Two test. Each Subject Two test appointment includes two attempts. If you fail the first attempt, you can take a free make-up test. If you do not take the make-up test or fail it, the test session ends. Within the validity period of the driving license learning process, you can schedule the Subject Two test no more than five times. If you fail the fifth attempt, all previously passed subjects will be invalidated. To continue learning for the driving license, you must restart the process from Subject One. For example, for a C1 license, the Subject Two test includes: Completing driving tasks within a designated area; demonstrating mastery of vehicle control skills; and assessing the ability to judge the vehicle's spatial position. Subject Two, also known as the "small road test," consists of five mandatory items: reverse parking, parallel parking, hill start, right-angle turn, and curve driving. Some regions include a sixth item: high-speed toll card collection. Subject Two test precautions: After getting into the car, always adjust the seat and mirrors to the proper position and state, and fasten the seatbelt. For parallel parking, find the correct angle quickly, turn the steering wheel swiftly, and coordinate with the vehicle's speed. For hill starts, remember to engage the handbrake, turn on the left turn signal, and release the handbrake. Stabilize the clutch while gently pressing the accelerator to avoid stalling or rolling back. For right-angle turns, react quickly after identifying the turning point and coordinate with the vehicle's speed to avoid deviation. For curve driving (S-turn), slow down and proceed cautiously. Those with good driving sense may pass through smoothly in one go. For reverse parking, control the speed carefully, identify reference points accurately, and make minor adjustments if deviations are observed in the mirrors. The driving test consists of three subjects: Subject One, Subject Two, and Subject Three. Subject One covers traffic safety laws, regulations, and related knowledge. Subject Two is the field driving skills test. Subject Three is divided into two parts: road driving skills and safe driving knowledge. The safe driving knowledge test is conducted after Subject Three, commonly referred to as Subject Four, though this term is not officially recognized in the regulations (i.e., Ministry of Public Security Order No. 123).

What does the red exclamation mark on the car dashboard mean?

The red exclamation mark (specifically a circle with an exclamation mark inside parentheses) represents a warning for the braking system, mainly indicating a brake system malfunction or low brake fluid level. Solution: The braking system should be inspected and repaired immediately to avoid accidents. Apart from the red exclamation mark indicating a brake system fault, other exclamation marks on a car are yellow, representing general faults, automatic transmission faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these four situations: General Fault: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a general performance or component/function fault in the car. Common issues include parking sensor faults, fuel cutoff system intervention or malfunction, external light faults, engine oil pressure sensor faults, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating a transmission fault or transmission lubricant level below the normal range. The transmission oil should be replaced promptly. Abnormal Tire Pressure: A horizontal line under parentheses with an exclamation mark in the middle. This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. The tire pressure should be checked and restored to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator, indicating a fault in the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or perform a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.

Why is the car fan making loud noise at high speed?

It may be due to excessive bearing wear. Check the radiator and surrounding components to see if the bearing is excessively worn. If so, simply replace the bearing. Also, inspect whether the blades of the cooling fan are rubbing against anything. If not, the fan may be damaged, and replacing the fan bearing or coupler should solve the issue. Below is an introduction to the electric fan: 1. Composition: The electric fan is designed to prevent the engine coolant temperature from getting too high. It consists of a sensor, the electric fan, a chip, and other components. 2. Function: When the coolant temperature generally exceeds 90 degrees, the sensor activates, and the electric fan turns on to lower the coolant temperature. In winter, when temperatures are lower and the coolant temperature is also lower, the electric fan usually does not operate, protecting the engine from working in excessively cold or hot conditions.

What is the safest way to drive when two vehicles meet in foggy weather?

When driving in foggy conditions and encountering another vehicle, the safest practice is to maintain low speed and a large following distance. Here are some precautions for driving in fog: 1. Proper use of lights: Turn on the fog lights when driving in fog. If the fog is extremely heavy, also turn on the hazard lights to avoid rear-end collisions and side-swipe accidents. Do not use high beams in foggy conditions. 2. Observe speed limits: In foggy areas, adjust your speed based on visibility. Use low-beam headlights, width markers, and tail lights, and increase the following distance appropriately while reducing speed. The speed should not exceed 20 km/h. 3. Avoid sudden braking: Sudden braking can cause the driver behind to react too late, leading to a rear-end collision. On highways, this can easily result in a chain-reaction collision. 4. Use the horn frequently: Frequent use of the horn helps other motorists, cyclists, and pedestrians determine your vehicle's position, thereby preventing accidents more effectively. When you hear another vehicle's horn, respond immediately by honking your own horn.

Why is one side of the car audio working while the other is not?

If one side of the car audio is working while the other is not, it may be due to the audio channel being adjusted to a specific speaker. It could also be caused by a broken power circuit of the speaker. You can check the wiring to see if it is clear or broken. If it is, simply reconnect the wiring. Another possibility is that the speaker is damaged and needs to be replaced if it is faulty. Below is an introduction to the car Bluetooth system: 1. Function: The car Bluetooth system is an in-vehicle wireless hands-free system designed based on wireless Bluetooth technology. Its main function is to connect with a mobile phone via Bluetooth for hands-free calls during normal driving, thereby freeing up hands and reducing the risk of traffic accidents. 2. Principle: Bluetooth technology is an open global standard for wireless data and voice communication. Its essence is to establish a universal radio air interface for communication environments between fixed or mobile devices, further integrating communication technology with computer technology, enabling various 3C devices to communicate or operate with each other over short distances without the need for wired or cable connections.
