The freezing point of antifreeze ranges from -40 to -60 degrees Celsius, while water freezes at 0 degrees Celsius. It is necessary to add antifreeze to the radiator when the temperature approaches 0 degrees Celsius. The functions of automotive antifreeze are: 1. Providing anti-corrosion protection for components of the cooling system; 2. Preventing scale formation to avoid reducing the radiator's heat dissipation efficiency; 3. Ensuring the engine operates within the normal temperature range. Precautions for using antifreeze include: 1. Regularly checking the antifreeze level and replenishing it promptly if it falls below the lower limit; 2. Observing whether the antifreeze has any turbid sediments and replacing it in time if turbidity is found; 3. Not mixing antifreeze of different colors as they vary by vehicle model; 4. Measuring the freezing point of antifreeze before winter to prevent it from freezing.

Can motorcycles commit traffic violations?

Motorcycles can commit traffic violations. Here is some extended information: Electronic monitoring: Modern electronic monitoring systems are not like the old ones. The old systems could easily miss motorcycles due to their small size and less noticeable magnetic field disruption, leading to under-detection. The current systems use virtual zones for capture, achieving a detection rate of over 99.9%. For a motorcycle violation to be confirmed, the electronic eye must capture two photos. Temporary signal storage: Electronic monitoring systems use induction lines to detect the pressure from vehicles on the road. Sensors collect this data and send it to a computer, where it is temporarily stored (this data is valid for one red-light cycle). Pulse signal: Within the same time interval (a red-light cycle), if two pulse signals are generated simultaneously, it is considered "valid." Simply put, if the front wheel crosses the line during a red light but the rear wheel does not, only one pulse is generated. Without two consecutive pulses, no photo is taken.

What does a triangular exclamation mark on a sedan's dashboard mean?

A triangular exclamation mark on a sedan's dashboard is a general fault indicator light, which may indicate a brake system malfunction. When this light comes on, first check if the handbrake is fully released. If the light remains on after releasing the handbrake, inspect whether the brake fluid level is normal or if the brake pads are too thin. Besides brake system malfunctions, the following situations can also trigger this light: 1. Overheating of the dry dual-clutch transmission clutch; 2. Fuel cutoff system intervention or malfunction; 3. External light failure; 4. Engine oil pressure sensor malfunction; 5. Traction control system warning or malfunction. There are various other lights on the car dashboard that reflect the vehicle's condition. Another common indicator is the oil warning light, which typically illuminates when the engine oil level is insufficient to lubricate the engine, and adding oil usually resolves the issue.

Do motorcycles have temporary license plates?

Motorcycles do have temporary license plates, similar to cars. The process for obtaining a temporary license plate for a motorcycle is basically the same as for a car. Here is some additional information: Purchase documents: When purchasing a motor vehicle from a legitimate manufacturer or dealer, you will receive relevant purchase documents. If the vehicle purchased is an imported car, you will receive (Certificate of Imported Goods, Import Vehicle Inspection Sheet, Motor Vehicle Purchase Invoice). Later, with these documents, you can go to the vehicle management stations of various traffic police teams that issue temporary license plates to apply for one. Important notes: However, it should be noted that only one temporary license plate is issued, and it should be mounted on the rear license plate holder of the vehicle, unlike temporary license plates for cars. Also, pay attention to the validity period to avoid penalties for driving with an expired plate. Additionally, be sure to comply with the special regulations for motorcycles in different provinces and cities.

How to adjust the pneumatic brake?

Pneumatic brake adjustment method: First, locate the adjustment nut on the rear wheel sprocket. Use a 17-19mm hex wrench placed on it and tap it with a small hammer. After adjustment, it will automatically return to position. Generally, turning it clockwise tightens it until it can't be turned further. For the brake caliper, loosen it counterclockwise and tighten it clockwise. When the vehicle is unloaded, use a jack to lift the axle, at which point the wheel can be manually pulled up, and then tighten it. The pneumatic brake, also known as a disc brake, air brake, pneumatic disc brake, or pneumatic-hydraulic brake, is one of the industrial transmission brakes. It uses air pressure to stop or decelerate moving parts in machinery. It features a simple structure, easy installation, durability against pressure, impact, and knocking, and a long service life. Generally, only the brake pads need replacement, which is quick and easy, utilizing magnetic effects.

Which lane should motorcycles take on the highway?

Motorcycles should drive in the outermost lane of the highway. Speed limit regulations: The speed of a motorcycle must not be lower than 60 km/h and must not exceed 80 km/h. Due to the minimum speed limit, motorcycles with an engine displacement below 50cc are "prohibited from entering." Precautions: When driving a motorcycle on the highway, carrying passengers is not allowed, and helmets must be worn. According to the speed limits set for different lanes on the highway, motorcycles should drive in the outermost lane. Introduction: Highways are classified as high-grade roads, commonly referred to as expressways. According to the "Technical Standards for Highway Engineering" by the Chinese Ministry of Transport, a highway is defined as "a road that can accommodate an average annual daily traffic volume of more than 25,000 passenger cars, is exclusively for high-speed divided-lane driving, and has full access control." Although different countries have different names for highways, they all refer to roads with at least four lanes, bidirectional separated traffic, full access control, and all-grade interchanges. In addition, many countries also refer to direct trunk roads with partial access control and not all-grade interchanges as highways.

What are the new regulations for off-site annual inspection of motorcycles in 2020?

2020's new regulations for off-site annual inspection of motorcycles stipulate that motorcycle inspections will implement nationwide universal inspection, further liberalizing cross-provincial (autonomous region/municipality) off-site inspections for motorcycles. Below is relevant information about the 2020 new regulations for off-site annual inspection of motorcycles: Main content: For motorcycles registered within 6 years, they will be exempt from inspection at inspection institutions to reduce the inspection burden on the public, especially owners in rural areas. Vehicle owners can apply for an inspection compliance mark at the vehicle management office of the registration location within three months before the expiration of the vehicle's inspection validity period. Before applying, the vehicle owner must resolve all traffic safety violations and accidents related to the vehicle. Legal basis: Article 49 of the "Motor Vehicle Registration Regulations". Vehicle owners can apply for an inspection compliance mark at the vehicle management office of the registration location within three months before the expiration of the vehicle's inspection validity period. Before applying, the vehicle owner must resolve all traffic safety violations and accidents related to the vehicle.
