The following situations prohibit U-turns: First, when there are signs prohibiting left turns or U-turns; second, when crossing solid lines for a U-turn is prohibited; third, when the central guardrail or green island is close to the stop line, a U-turn is not allowed during a red light; fourth, U-turns are prohibited on pedestrian crossings. The regulations regarding U-turns are as follows: 1. Motor vehicles are not allowed to make U-turns at locations with signs or markings prohibiting U-turns or left turns, as well as at railway crossings, pedestrian crossings, bridges, sharp curves, steep slopes, tunnels, or sections of road prone to danger. 2. Motor vehicles may make U-turns at locations without signs or markings prohibiting U-turns or left turns, provided they do not obstruct the passage of other normally moving vehicles and pedestrians.

Before driving every time, I always check the traffic rules. Under what circumstances is a U-turn not allowed? The most basic rule is that U-turns are absolutely prohibited in areas with 'No U-turn' signs, such as intersections or specific road sections where these signs are often displayed. Additionally, at traffic light intersections, if there is no specific green light signal permitting a U-turn, you cannot make a U-turn even if the light is green, especially when pedestrians are crossing the road; U-turns are absolutely not allowed on pedestrian crossings as they can block pedestrians and easily cause accidents. Other situations include areas near railway crossings where making a U-turn is highly dangerous—if a train comes, it could be disastrous; on sharp curves or steep slopes where visibility is limited, making a U-turn might lead to collisions with other vehicles. In short, following the rules not only helps avoid fines but also saves lives. I always remind myself to pay extra attention to these points.

With twenty years of driving experience, the first thing that comes to my mind when encountering a no-U-turn situation is safety. For example, U-turns are prohibited on highways because the speed is too fast—attempting one would be suicidal. In tunnels or on narrow bridges, the space is too limited, making the maneuver difficult, and it's also prohibited by law. Near school zones or bus stops, where students or pedestrians frequently appear, making a U-turn can easily lead to accidents. In bad weather, like heavy fog, even if there's no sign, I never make a U-turn to avoid losing control. U-turns are especially dangerous on curves due to poor visibility and delayed reaction. The key is to develop a habit—prefer taking a longer route over risking lives. Driving isn't about speed; it's about arriving home safely.

Last time I drove downtown and almost got fined when trying to make a U-turn, which taught me a lesson. Under what circumstances are U-turns prohibited? Simply put: don't attempt when traffic signals don't permit it; absolutely never on pedestrian crossings as it's strictly regulated by law; no U-turns within 50 meters before or after railway crossings due to high risks; avoid trying on steep slopes or sections with poor visibility; U-turns on highways are illegal unless in designated areas; bus lanes are also prohibited as they disrupt public transport. The key is to observe surroundings – always follow police instructions when present, and beware of surveillance cameras that easily capture violations. Drive cautiously; I often check my route before acting to avoid mistakes.

Is It Necessary to Buy an MPV?

It is recommended to buy an MPV, but the decision should still be based on individual circumstances and usage. Introduction to MPV: MPV (Multi-Purpose Vehicles) is a multi-purpose vehicle evolved from station wagons. It combines the spacious passenger space of a station wagon, the comfort of a sedan, and the functionality of a van, typically featuring a two-box structure and seating for 7-8 people. Target Users of MPV: It is primarily designed for family users, offering more space than sedans of the same displacement, and comes in various sizes and specifications. Features of MPV: MPVs generally adopt a sedan chassis, with the engine layout breaking the traditional van design where the engine is placed inside the cabin. Instead, the engine is transversely mounted in the front, which helps absorb frontal impacts and enhances the safety of front-seat passengers.

How many points are deducted for driving in the wrong direction on an elevated road?

Driving in the wrong direction on an elevated road will result in a deduction of 3 points and a warning or fine.

For fines imposed on pedestrians, passengers, and non-motor vehicle drivers, if the party concerned has no objection, the fine may be collected on the spot. The fine shall be issued with a unified fine receipt issued by the finance department of the province, autonomous region, or municipality directly under the central government. If the unified fine receipt issued by the finance department is not provided, the party concerned has the right to refuse to pay the fine. Motor vehicle drivers who commit any of the following violations will be penalized with a deduction of 3 points: Driving a motor vehicle in violation of prohibition signs or prohibited line markings, driving a motor vehicle without overtaking, yielding, or driving in the wrong direction as required, driving a motor vehicle in violation of regulations when towing a trailer, failing to use lights and set up warning signs as required after a vehicle breaks down or is involved in an accident on the road, and driving a motor vehicle on the road without undergoing regular safety technical inspections as required.

What temperature is generally considered too high for an engine?

Engine overheating generally refers to temperatures above 105 degrees Celsius. Lack of coolant: Insufficient or inappropriate coolant cannot effectively dissipate the heat generated by engine components, leading to excessively high water temperature. Cooling system malfunction: Blockages in the radiator guard mesh or core ventilation passages by debris can result in poor heat dissipation. A faulty cooling fan may also prevent timely heat transfer to the antifreeze during high-speed operation, causing the antifreeze temperature to rise and leading to issues like boiling over. Thermostat malfunction: If the thermostat is not functioning properly, it can cause the engine to overheat. This can usually be diagnosed by checking the temperature difference between the small hoses connected to the thermostat. A significant temperature difference between the two hoses indicates a faulty thermostat. In such cases, it is advisable to seek professional maintenance services for inspection and repair.

What Causes the Brake Noise on the Leoncino 500?

The brake noise on the Leoncino 500 may be caused by oil contamination on the brake pads or severe wear of the brake blocks. Below are the detailed explanations of the causes and solutions: Oil contamination on the brake pads: Brake pads are generally composed of steel plates, adhesive insulation layers, and friction blocks. Their material is prone to oil contamination. During braking, if the brake shoes slip against the brake drum due to oil contamination, it can produce a sharp, piercing sound. The brake pads can be removed and cleaned with alcohol to wash the brake drum and brake shoes, removing the oil contamination. To further increase the friction of the brake pads, you can sand the surface of the brake pads with sandpaper, which not only eliminates brake noise but also enhances braking friction, improving braking performance. Severe wear of the brake blocks: If you need to apply more force to brake and the process is accompanied by abnormal noise, it may indicate severe wear of the brake blocks. It is advisable to visit an after-sales service or repair shop as soon as possible for inspection and replacement of the brake blocks. Continuing to use them could lead to dangerous situations.

What does it mean when the side airbag for occupants is turned off?

The side airbag for occupants being turned off means that the side airbag automatically deactivates when it cannot detect a person on the seat. If you sit in the passenger or driver's seat with an incorrect posture, the side airbag may not detect your presence within its effective range, causing it to automatically deactivate. Try adjusting your sitting position. The electronic control of the airbag system is a passive safety protection system. When used in conjunction with seat belts, it provides effective collision protection for passengers. In the event of a car collision, the airbag can reduce head injury rates by 25% and facial injury rates by approximately 80%.
