How Long Can a Temporary License Plate for Small Cars Be Used?

Temporary license plates for small cars come in two types: one is for temporary driving within the administrative jurisdiction, issued with a validity period not exceeding 15 days, and the color is blue; the other is for temporary driving across administrative jurisdictions, issued with a validity period not exceeding 30 days, and the color is yellow. Below is relevant information about temporary license plates: 1. Characteristics: The characteristic of temporary license plates lies in their temporariness. Unlike formal license plates, which can be permanently valid, once a temporary license plate expires, the holder cannot drive on the road without renewal, otherwise it constitutes a traffic violation. 2. Validity Period: New cars using temporary license plates must not exceed 15 days, and the owner should promptly apply to the vehicle management authority for a formal license plate.

Where is the car computer located?

The vehicle computer is installed in the driver's compartment, specifically below the steering wheel. The vehicle computer, also known as the Electronic Control Unit (ECU), functions as a computer-controlled module. The ECU, referred to as "vehicle computer" or "on-board computer," is essentially the brain of the car. In terms of functionality, it serves as a specialized microcomputer controller for automobiles. Similar to a standard computer, it consists of a microprocessor (CPU), memory (ROM, RAM), input/output interfaces (I/O), analog-to-digital converters (A/D), and large-scale integrated circuits for signal conditioning and driving. To put it simply, "the ECU is the brain of the car." The ECU collects data from various sensors (including temperature sensors, pressure sensors, rotation sensors, flow sensors, position sensors, oxygen sensors, knock sensors, etc.) that monitor the engine's operating conditions. These signals are transmitted to the ECU via dedicated wiring. Upon receiving these signals, the ECU analyzes them to determine the operational status of various engine components and then performs automated calculations based on pre-programmed algorithms. Functions of the vehicle computer system: The vehicle computer typically calculates real-time fuel consumption, travel distance, temperature, average speed, average fuel consumption, etc. Some systems also include features like maintenance reminders and driver rest alerts. Not all fuel-injected vehicles are equipped with a vehicle computer, although most modern cars have one, albeit with varying levels of functionality. Modern vehicles are predominantly fuel-injected, and even older carburetor-equipped high-end models may have a vehicle computer. Generally, the vehicle computer is displayed on a small screen located either on the instrument panel or the center console, providing the driver with the aforementioned information for reference.

What does the locked status of a car mean?

Vehicle locking is a management measure implemented by the vehicle management office, which can be due to various factors such as court seizure or unresolved accidents. Once a vehicle is locked, it cannot be driven on the road. If your car is locked, don't panic. First, identify the reason, then take timely action to resolve the issue, ensuring it doesn't affect your vehicle usage. Vehicles are considered special movable properties, and their seizure period should not exceed two years. If the seizure period expires without an extension procedure, the lock will be automatically lifted. Here are the relevant regulations: Article 8 of the Road Traffic Safety Law: The state implements a registration system for motor vehicles. Motor vehicles can only be driven on the road after being registered with the traffic management department of the public security authority. For motor vehicles that have not yet been registered but need temporary road use, a temporary pass must be obtained. The vehicle management office is only responsible for the locked status. To unlock the vehicle, a certificate from the court or the unit that requested the lock must be provided.

Will points be deducted for entering the straight-ahead waiting area early?

Entering the straight-ahead waiting area early does not result in point deductions. The waiting area is designed to alleviate traffic pressure by allowing left-turning vehicles to enter and wait in advance when straight-through traffic is permitted. Below are relevant explanations: 1. Straight-ahead waiting area: This means the intersection first releases left-turning vehicles, then straight-moving vehicles. When the left-turn signal turns green to release left-turning traffic, straight-moving vehicles can proceed into the straight-ahead waiting area. They can then quickly pass through the intersection when the straight signal turns green. 2. Left-turn waiting area: The left-turn waiting area is the lane entered when the left-turn signal is red but the straight signal is green. Its rules differ from those of the straight-ahead waiting area.

Is China 6 more fuel-efficient than China 5?

China 6 vehicles have higher fuel consumption than China 5 vehicles. China 6 is the latest national emission standard, which has been implemented in many cities or regions since 2019. The following is the relevant introduction of the emission standard: 1. Reason: As global environmental pollution problems become increasingly severe, countries around the world are introducing stricter emission standards. 2. Function: Strict emission standards are used to restrict automobile manufacturers. Under strict emission standards, automobile manufacturers will actively develop new technologies to reduce engine exhaust emissions. 3. Development trend: Pure electric vehicles are the future development trend of automobiles. Pure electric vehicles have no exhaust emissions, which is beneficial to environmental protection.

Is it necessary to install mud flaps on sedans?

It is necessary to install mud flaps on sedans. Here are the specific details about car mud flaps: 1. Function: The primary purpose of car mud flaps is to block mud. During rainy weather, especially on muddy roads, car tires often accumulate a lot of mud, which can sometimes splash onto the car body. Installing mud flaps helps protect the car from mud and debris. 2. Material: Mud flaps are plate-like structures installed behind the wheel frames, typically made of high-quality rubber or sometimes engineering plastic. 3. Installation effect: Mud flaps are usually installed as metal, leather, plastic, or rubber panels behind the vehicle's wheels. After installation, the mud flaps protrude about 5cm from the car body, effectively preventing flying stones and gravel from damaging the car's paint surface.
