The leftmost high-speed lane has a speed limit of 100-120 km/h, while the middle lane has a speed limit of 60-100 km/h. The specific lane speed limits should be determined based on the road signs at the location. Here are some key points to note regarding speed limits: Signage Speed Limits: Speed limits are enforced according to the signs and markings on the highway. There is no uniform regulation for these speed divisions, as they may vary between different regions or even different sections of the same highway. Drivers must always pay attention to the posted speed limits while driving. Legal Speed Limits: These refer to the speed limits stipulated in the "Road Traffic Safety Law" and its implementation regulations. For example, on roads without a centerline, the speed limit is 40 km/h; on roads with only one motor vehicle lane in the same direction, the speed limit is 70 km/h; when entering or exiting non-motorized lanes, passing railway crossings, sharp curves, narrow roads, narrow bridges, or making U-turns, turns, or descending steep slopes, the speed limit is 30 km/h. The maximum speed limit on highways is 120 km/h.

I have experienced various lane situations while driving on highways. On two-lane highways, the left lane typically has the highest speed limit of around 120 km/h and is used as the overtaking lane; the right lane has a slightly lower speed limit, approximately 100 to 110 km/h, suitable for slower or larger vehicles. Three-lane highways are more distinct: the left lane is the fast lane with a speed limit of 120; the middle lane is for normal driving, between 110 and 120; and the right lane is for deceleration or exiting, around 100. I never exceed the speed limit, keeping it within a reasonable range to avoid sudden lane changes that could cause accidents. It's also important to pay attention to traffic flow—during peak hours, the left lane can easily get congested, so I always observe road signs in advance and adjust accordingly. Maintaining a safe distance is crucial; I avoid tailgating to handle unexpected situations. After every highway drive, I reflect on my speed control to develop good habits.

What are the rules for making a left turn at a traffic light intersection?

The rules for making a left turn at a traffic light intersection are: If there is a dedicated arrow signal, you must follow its indication; if there is no dedicated arrow signal, left-turning vehicles can turn left when the straight-through light is green, provided they do not interfere with oncoming straight-moving vehicles. U-turns are permitted unless there is a 'No U-turn' or 'No Left Turn and U-turn' sign. According to regulations, motor vehicles are prohibited from making U-turns at locations with 'No U-turn' or 'No Left Turn' signs and markings, as well as at railway crossings, pedestrian crossings, bridges, sharp curves, steep slopes, tunnels, and other hazardous sections. The time and process required for completing both straight and left turns in two directions at an intersection are referred to as the phase, which is determined based on calculated traffic flow at each intersection.

What are the symptoms of oil shortage in an automotive air conditioning compressor?

What phenomena occur when an air conditioning compressor lacks oil: Low efficiency: Reduced efficiency, resulting in very poor cooling (or heating). The compressor frequently goes into protection mode (increased wear due to oil shortage leads to lower compressor temperature). Seizure: The compressor often seizes, especially when there is a significant temperature difference between indoor and outdoor environments. The air conditioning compressor functions to compress and drive the refrigerant in the air conditioning refrigeration cycle. It is typically installed in the outdoor unit. The compressor draws refrigerant from the low-pressure area, compresses it, and delivers it to the high-pressure area for cooling and condensation. Heat is dissipated into the air through the radiator, and the refrigerant changes from a gaseous to a liquid state, with increased pressure.

What Causes Brake Failure in Electric Vehicles?

Electric vehicle brake failure can be attributed to the following reasons: Lack of maintenance on the braking system: Excessive impurities in the brake master cylinder, poor sealing, failure of the vacuum booster pump, contaminated brake fluid or mixing different types of brake fluid causing vapor lock when heated, leakage in the brake master cylinder or wheel cylinder, and air leaks in the air reservoir or pipeline connections. Improper operation: Mechanical failure due to improper operation, such as prolonged downhill driving causing the brake pads to overheat from friction, carbonization of the brake drum, and complete loss of braking function. Severe overloading: Severe overloading increases the vehicle's momentum due to gravitational acceleration, directly leading to brake failure.

Why does the car air conditioner stop blowing air after prolonged use?

Car air conditioner stops blowing air after prolonged use due to the following reasons: Lack of refrigerant: Refrigerant loss is mainly caused by leaks. If the car's air conditioner is not cooling properly and stops cooling again after adding refrigerant for a while, you should be cautious. Generally, this situation indicates a significant issue. If the condenser is leaking, it needs to be replaced. To check for leaks, fluorescent dye is usually added to the refrigerant oil, and a specialized viewing glass is used to locate the leak points. Dirty condenser: The air conditioner condenser and radiator are located at the front of the car. When the vehicle is moving, air enters through the central grille, carrying debris such as fluff and leaves, which can accumulate on the air conditioner condenser and radiator.

Is Car Heat Insulation Film Applied on the Inside or Outside?

Car window film should be applied on the inside of the car glass because installing it on the interior side protects it from wind and rain, slowing down aging and thus extending its service life. Below is relevant information: Heat and Sun Protection: The film can effectively block a significant amount of heat generated by infrared rays. UV Protection: Medium and long waves of ultraviolet rays can penetrate thick glass, but applying heat insulation film can block most UV rays, preventing skin damage and reducing the aging of car interiors. Safety and Explosion Protection: The base layer of the film is made of polyester, which provides excellent tear resistance and puncture prevention. Combined with the adhesive layer of the film, the strengthened glass can prevent injuries to drivers and passengers caused by accidental glass breakage.

Can you park for a long time in N gear without turning off the engine?

You can park for a long time in N gear without turning off the engine. Here is an introduction about the engine: 1. Introduction: An engine (Engine) is a machine that can convert other forms of energy into mechanical energy. 2. History: The first external combustion engine was invented by R. Stirling in the UK (Scotland) in 1816, which was later improved by Watt into a steam engine. 3. Function: The engine can be used as a power generation device or refer to the entire machine including the power device (such as a gasoline engine or an aircraft engine). Its types include internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines and steam engines), gas turbines (used in racing cars), electric motors, etc.
