According to regulations from the national transportation department, the speed limits for four-lane highways are as follows: 1. First lane: 100-120 km/h (generally dedicated to passenger vehicles); 2. Second lane: 80-100 km/h; 3. Third lane: 60-100 km/h; 4. Fourth lane: emergency lane. Some highways may have additional regulations, which should be followed as indicated by road markings. On roads without speed limit signs or markings, motor vehicles must not exceed the following maximum speeds: 1. Roads without a centerline: 30 km/h for urban roads and 40 km/h for highways; 2. Roads with only one lane in the same direction: 50 km/h for urban roads and 70 km/h for highways.

I've driven on highways countless times. When encountering a four-lane highway, usually the leftmost lane is the overtaking lane with a maximum speed limit of 120 km/h, specifically designed for quick overtaking but shouldn't be occupied for long periods to avoid camera fines. The middle two lanes are normal driving lanes, with speeds controlled between 100-120 km/h to maintain smooth traffic flow. The rightmost lane is designed for large vehicles and slow-moving traffic, with speed limits around 60-100 km/h. Pay attention to speed signs as specific sections may vary. During rainy or foggy conditions, it's crucial to reduce speed further - I maintain a 150-meter following distance to prevent rear-end collisions. Safety comes first, as many accidents each year are caused by speeding. I recommend beginners practice more before hitting the road.

Just got my driver's license and drove on the highway. I've figured out the rules for the four-lane road: the left lane has a speed limit of 120 km/h, reserved for overtaking, but driving too fast can easily lead to loss of control. The middle two lanes have speeds between 100 to 120 km/h, providing a stable and normal driving experience. The right lane has a lower speed limit, around 60 to 100 km/h, designated for trucks and slower vehicles. My instructor taught me to only overtake from the left and avoid reckless lane changes, otherwise, a ticket might come flying. Once, during a rainy night drive, I reduced my speed to 80 km/h and turned on the high beams to see the road signs. Always remind myself not to exceed the speed limit, as speed cameras are everywhere.

Driving on the highway during long trips is much smoother with four lanes. The left lane has a speed limit of 120 km/h, making overtaking convenient and quick. The middle two lanes maintain a steady speed between 100 to 120 km/h. The right lane serves as a buffer with a lower speed limit, ranging from 60 to 100 km/h, accommodating slower vehicles entering or exiting. When passing through mountainous areas, I slow down to enjoy the scenery, as safety is more important. In case of traffic jams, I switch lanes to take a break, remembering to turn on navigation for speed limit alerts. High-speed driving is about rhythm; don’t sacrifice safety for speed.

What does the yellow background 30km/h sign mean?

The yellow background 30km/h sign actually indicates an advisory speed, meaning the traffic authority recommends drivers to maintain this speed when passing through this section. This sign does not mandate driving below 30km/h. Below are the meanings of different colored signs: 1. Yellow rectangle with numbers: Advisory speed sign - the number indicates the recommended passing speed for this section. 2. Blue circle with white background and white numbers: Minimum speed sign - the number indicates the minimum speed of 50km/h for this section. 3. Red circle with black numbers: Maximum speed sign - the number indicates the maximum speed of 40km/h for this section.

Can Car Air Conditioning Provide Heating?

Heating is generated by utilizing the car's own heat circulation system and does not require the compressor to work. Here are the relevant details: 1. Internal Circulation: Internal circulation primarily prevents external dust and harmful gases from entering the car in a timely and effective manner. For example, when driving through areas with smoke, dust, unpleasant odors, or in heavy traffic, it blocks harmful exhaust emissions from vehicles ahead. Another function is to maintain warmth. 2. External Circulation: External circulation mode uses a fan to draw outside air into the car, meaning the air passage between the outside and inside of the car is open. The air blown by the fan comes from outside, so even if the fan is off, airflow is still drawn into the car while driving, replenishing fresh air inside. Sometimes, you may feel airflow even when the fan is off, which is due to the external circulation setting being enabled.

How to Solve Low Tire Pressure?

Solutions for low tire pressure: Visually inspect whether the tire can still continue to drive. If possible, drive to a nearby tire repair shop for assistance; If the tire pressure is too low to drive, use a car air pump to inflate it, then proceed to a nearby repair shop for inspection; Replace with a spare tire and then go for repairs; Low tire pressure due to cold temperatures is normal and will return to normal after the car runs for a while; Reinstall the tire edge with the wheel rim. Hazards of low tire pressure: Increases friction coefficient with the road surface, leading to higher fuel consumption; Causes heavy steering and easy deviation, which are factors detrimental to driving safety; Increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; Reduces the function of the cord and rubber, leading to delamination or cord breakage, excessive friction with the rim, causing damage to the bead area and abnormal wear; Multiplies friction between the tire and the ground, sharply raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to a tire blowout; Increases tire body deformation, making the tire side prone to cracks, while generating flexing motion, leading to excessive heat, promoting rubber aging, fatigue of the cord layer, cord breakage, and also increasing the tire's contact area with the ground, accelerating shoulder wear.

How many days after window tinting can I roll down the windows?

After applying window tint, you should wait at least seven days before rolling down the windows. Here are some important precautions regarding window tinting: 1. Avoid rolling down windows for the first week: When car windows are tinted, the film is applied to the entire window surface and requires time to cure. Opening windows before the film has fully cured may cause bubbling at the edges. 2. Try not to wipe the windows for the first week: Tinted windows are prone to fogging, and using a towel to wipe them may cause the film to shift. 3. Do not wash the car for three days after tinting: After window tinting, it's best to park the car in a sunny location to ensure complete evaporation of moisture trapped under the film. Washing the car within three days of tinting is strictly prohibited to prevent the film from peeling off.

What is the reason for the buzzing sound at 120 km/h?

The reasons for the buzzing sound at 120 km/h are as follows: 1. Excessive tire pressure: When using the car, the tire pressure should be adjusted within the standard range (usually 2.3bar-2.5bar). If the tire pressure is too high, it will cause severe wear on the tire tread, reduce the tire's shock absorption performance, and make the tire noise more noticeable. 2. Abnormal tire wear: The tire tread comes into contact and friction with the ground. If the tread wears unevenly and has bumps, it will produce a buzzing sound. 3. Damaged wheel hub bearing: Worn wheel hub bearings will cause a buzzing sound due to long-term use leading to wear and looseness. To protect the wheel hub bearings, avoid violent impacts on the wheels and prolonged driving through water during normal use.

How to Drive Through Waterlogged Roads in Rainy Weather?

Here are the techniques for driving through waterlogged roads in rainy weather: 1. When encountering water accumulation on the road while driving: Slow down or stop to observe. If the water level reaches two-thirds of the bumper or tire height, proceeding further poses certain risks. High speed increases the actual water depth the car passes through, potentially allowing water to enter the cabin from the engine compartment or chassis. Avoid driving against waves created by large vehicles. If the water level is high, try to detour instead of forcing your way through. 2. While driving through water, besides maintaining a low speed: Try not to stop, shift gears, release the throttle, or accelerate. Instead, drive at a steady speed with low gear and moderate throttle. Avoid speeding through, which can create large waves or splashes. 3. If the car stalls in water, do not attempt to restart it immediately: Take measures to tow the car to a safe location with less water as soon as possible. Serious water ingress into the engine can occur if water enters through the air filter into the intake valve and then into the cylinder via the intake pipe. Do not try to restart the engine, as this may cause deformation of critical components like the crankshaft and connecting rods, leading to engine vibration or even component breakage. Stalling in water likely means the engine has taken in water; after stalling, only tow the car in neutral to a repair shop for cleanup. 4. After driving through water, promptly remove moisture from the brake pads: Drive at low speed while lightly pressing the throttle and gently applying the brakes. For those who can't multitask, repeatedly apply the brakes several times at slow speed to generate friction heat between the brake drum and pads, evaporating the moisture.
