Do I need to wait for the traffic light at an intersection with a U-turn sign on the ground?

If the U-turn signal light is red, you must wait to make a U-turn; otherwise, it will be considered running a red light. According to the "Road Traffic Safety Law," this offense carries a penalty of: 6 demerit points and a fine of 200 yuan. If there is no U-turn signal light, and the gap is marked with a dashed line, the U-turn is not affected by the traffic signal and does not require crossing the pedestrian crossing. If the gap is marked with a solid line, the U-turn must cross the pedestrian crossing and is subject to the left-turn signal light. Making a U-turn directly may result in being photographed or penalized by on-site traffic police. When making a U-turn that requires crossing the pedestrian crossing, yielding to pedestrians is necessary: If pedestrians are walking on the right side of the crosswalk and have not reached the centerline of the road, vehicles on the left side of the road should slow down and proceed only after ensuring safety. If pedestrians are waiting outside the boundary line of the motorized and non-motorized lanes and have not entered the road, vehicles should slow down and proceed only after ensuring safety. If pedestrians cross the boundary line between the motorized and non-motorized lanes, vehicles that do not stop and yield are committing a violation and should be penalized. After pedestrians enter the motorized lane (Lane A) via the crosswalk, vehicles in Lane B should slow down and proceed only after ensuring safety. If vehicles in Lane A do not stop and yield, it is a violation and should be penalized. If pedestrians are waiting at the centerline of the road without entering the motorized lane, vehicles that do not stop and yield are committing a violation and should be penalized. If pedestrians cross the centerline of the road and enter the motorized lane, vehicles that do not stop and yield are committing a violation and should be penalized. If the road is divided by a green belt, and pedestrians are waiting in the central stopping area, vehicles must slow down and proceed only after ensuring safety. Scenarios where U-turns are allowed: If there is a clear U-turn sign at the intersection, a U-turn is permitted. If there is a U-turn signal light, follow its instructions. If there is no signal light, make the U-turn based on the specific situation, ensuring it does not hinder other vehicles or pedestrians. If there is no explicit prohibition of U-turns or left turns at the intersection, a U-turn is allowed. "No explicit prohibition" means the absence of "No U-turn" or "No Left Turn" signs and the absence of solid lines in the center of the road. In such cases, U-turns are permitted. U-turns are also allowed on yellow grid lines. Yellow grid lines are no-parking zones marked at intersections prone to congestion due to temporary parking, important unit entrances, and other necessary locations. Parking on these grid lines (including waiting for traffic lights) is a violation. Although parking is prohibited in yellow grid zones, U-turns are allowed. As long as there is no central barrier, yellow grid lines are equivalent to "U-turn permitted." If there is a U-turn signal light at the intersection, follow its instructions—only proceed on green. If "No Left Turn" and "U-turn Permitted" signs appear together, U-turns are allowed but left turns are prohibited. Note that "No U-turn" is not the same as "No Left Turn." Precautions when making a U-turn at an intersection: Observe the road markings. If they are solid lines, U-turns are prohibited under any circumstances. Continue driving to find a suitable U-turn location. If there is a "No Left Turn" sign ahead, even if there is no mention of prohibiting U-turns, U-turns are not allowed at that intersection because U-turns and left turns are similar maneuvers, and U-turns always involve a left turn first. U-turns must be made from the innermost left-turn lane. If you are in the second left-turn lane, U-turns are not permitted at that intersection. Always yield to straight-moving vehicles when making a U-turn. Proceed only if it does not interfere with the normal flow of straight-moving vehicles; otherwise, you will bear full responsibility for any accident. Near the intersection stop line, lanes usually have guiding arrows for vehicle selection. The leftmost lane does not always have a left-turn arrow. If a straight arrow appears on some roads, even without explicit "No U-turn" signs, U-turns are not allowed.

What cars have active suspension?

Active suspension is available in models such as the Mercedes-Benz S-Class, BMW 7 Series, Audi A8, Cadillac CT6, and Land Rover Range Rover. Active suspension refers to a system where the stiffness and damping characteristics of the suspension can dynamically adapt based on the vehicle's driving conditions, ensuring the suspension system always provides optimal shock absorption. Taking the 2021 Land Rover Range Rover as an example, its body structure is a five-door, five-seat SUV with dimensions of 5000mm in length, 2073mm in width, and 1869mm in height, a wheelbase of 2922mm, a minimum ground clearance of 220mm, and a fuel tank capacity of 104 liters.

How to Deal with Abnormal Noises from Car Air Conditioning?

When there is abnormal noise from the car air conditioning, it is necessary to determine whether the noise is coming from inside or outside the air conditioning system. Abnormal noises inside the air conditioning system are often caused by moisture or air in the refrigerant. When the refrigerant expands, it can produce noise, and the refrigerant can be directly replaced. If too much refrigerant is added, it can also cause abnormal noise, and a small amount can be released appropriately. Below is information about abnormal noises from car air conditioning: 1. Common factors causing abnormal noises from car air conditioning include: Issues with the compressor electromagnetic clutch are a common cause of compressor noise. Since the compressor often operates under high load conditions, shifting from low to high speeds, the demands on the electromagnetic clutch are high. Additionally, the electromagnetic clutch is usually installed close to the ground and frequently exposed to rain and dirt. When the bearings inside the electromagnetic clutch are damaged, abnormal noise occurs. 2. The tension of the compressor drive belt can also cause abnormal noise from the car air conditioning compressor. If the compressor drive belt is too tight or too loose, it can affect the lifespan of the electromagnetic clutch. If the drive belt is too loose, the electromagnetic clutch is prone to slipping. If the drive belt is too tight, the load on the electromagnetic clutch increases. Improper tension of the drive belt can, at best, cause the compressor to stop working, and at worst, lead to compressor damage.

Can a Car Run Long Distance in 40°C High Temperature Weather?

40°C high temperature weather is suitable for long-distance car travel. Precautions: 1. Check the vehicle before departure: Conduct a comprehensive inspection of the vehicle, including checking for oil or water leaks (look for any oil or water stains on the ground under the car); measure tire pressure to ensure it is appropriate; check the engine oil condition (pull out the dipstick to see if the oil color is normal and the oil level is correct). 2. Refuel in time: Fill up the tank before a long trip, and refuel at major gas stations along the way when the fuel level drops below half. Do not wait until the fuel warning light comes on to look for a gas station, as this can be very inconvenient. 3. Prevent fatigue driving: Long-distance driving should first avoid fatigue. Fatigue driving is one of the main causes of accidents. 4. Check tires: Before the trip, check the wear on the tire surface for bulges, cracks, or damage caused by blunt objects. If such issues exist, repair or maintain them before the trip. If possible, remove the tires to check for any damage on the inner side, as hidden damage is often the main cause of accidents. 5. Children should sit in the back seat: During long-distance driving, children should not be seated alone in the front seat. Many cars have airbags installed in the front passenger seat, and the force of the airbag deployment, while protecting adults, can cause accidental injuries to children.

Reasons for Engine Shaking While Driving

Reasons for engine shaking while driving: 1. Damaged spark plugs: Wear of the spark plug electrode gap can lead to insufficient spark plug ignition, resulting in incomplete combustion of the air-fuel mixture, which causes the car to shake during acceleration. Additionally, cracks in the ceramic part of the spark plug can prevent ignition, causing one cylinder to stop working, which also leads to shaking during acceleration. In such cases, the spark plugs should be replaced. 2. Poor fuel quality: Low-quality gasoline can result in poor atomization by the fuel injectors, leading to incomplete combustion of the air-fuel mixture in the cylinders, which can cause the engine to shake and lose power. It is recommended to use higher-grade gasoline after finishing the current tank and to perform a fuel system cleaning. 3. Excessive carbon buildup: A dirty throttle body or excessive carbon deposits on the fuel injectors can cause the throttle to not close properly or the idle control motor to stick, leading to high idle speeds. Carbon buildup generated during engine operation can also cause vehicle shaking, especially when starting the car. The engine may shake more than usual, and in severe cases, it may fail to start on the first attempt. 4. Unstable fuel pressure: If you have already cleaned the engine carbon deposits, changed the oil and spark plugs, but still notice shaking at idle, it is recommended to visit a 4S shop to check the fuel supply pressure and the intake pressure sensor. Abnormal fuel pump pressure or incorrect readings and malfunctioning of the intake pressure sensor can cause the vehicle to shake. In such cases, check the fuel pressure and replace components if necessary.
