Under What Traffic Signals Can You Make a U-Turn?

Motor vehicles can make a U-turn at locations where there are no prohibitions against U-turns or left turns indicated by signs or markings, provided they do not hinder the normal passage of other vehicles and pedestrians. When making a U-turn, if there is a dedicated U-turn signal light, the vehicle must wait until the dedicated U-turn signal turns green. If there is no U-turn signal but a left-turn arrow signal, the U-turn should be made when the left-turn arrow is green. If only a full-circle signal is present, the U-turn should be made when the full-circle signal is green. 1. Vehicle Traffic Signals: Vehicle traffic signals consist of green, yellow, and red lights. When the green light is on, vehicles are permitted to proceed, but turning vehicles must not obstruct the passage of straight-moving vehicles or pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue to proceed. When the red light is on, vehicles are prohibited from proceeding. 2. Lane Signals: Lane signals consist of a green arrow light and a red X-shaped light or red arrow light. When the green arrow light is on, vehicles in that lane are permitted to proceed in the indicated direction. When the red X-shaped light or red arrow light is on, vehicles in that lane are prohibited from proceeding. 3. Pedestrian Crossing Signals: Pedestrian crossing signals consist of a green light and a red light. When the green light is on, pedestrians are permitted to cross the pedestrian crossing. When the red light is on, pedestrians are prohibited from entering the pedestrian crossing, but those who have already entered may continue to cross or wait at the centerline of the road.

After driving for so many years, I've found that making a U-turn mainly depends on three types of traffic lights: dedicated U-turn lights, left-turn arrows, and full-circle green lights. If you see a dedicated green arrow for U-turns, feel free to turn around confidently. Without a dedicated U-turn light, watch the left-turn arrow—once it turns green and there's no 'No U-turn' sign posted, go ahead and make your turn. The most unique case is the circular green light: as long as the intersection doesn't prohibit U-turns, you can turn around safely while yielding to through traffic. Just remember, never cross solid yellow lines—for double yellow lines, find a dashed section to make your U-turn. Last week at a downtown intersection, I saw someone get caught on camera crossing a solid line for a U-turn—3 points deducted and a 200-yuan fine, what a loss.

What Causes the Car Air Conditioner Evaporator to Freeze?

Here is a detailed introduction to the causes of car air conditioner evaporator freezing: 1. Expansion valve: The adjustment range of the expansion valve is too small, resulting in excessively low low-pressure. 2. Refrigerant: Insufficient refrigerant in the system leads to excessively low evaporation pressure. 3. Internal circulation: The internal circulation filter is clogged. 4. Temperature control failure: The temperature control (or temperature sensor) malfunctions, causing the compressor to run continuously. 5. Variable displacement compressor: The energy control valve (pressure regulating valve) of the variable displacement compressor fails, keeping the compressor operating at full capacity, resulting in excessively low low-pressure and evaporator freezing.

What are the signs of abnormal car tires?

When there is an abnormality in the tire, such as abnormal tire pressure, a warning light will illuminate. The tire pressure warning light resembles an exclamation mark enclosed in parentheses, with a patterned line at the bottom, similar to the tread of a tire. The entire symbol looks like a cross-section of a tire. Relevant information about tire pressure is as follows: 1. Introduction: Tire pressure, strictly speaking, refers to the pressure of the air inside the tire. In car maintenance, the engine is the heart of the car, and damage to the engine will lead to the end of the car's life. Similarly, tire pressure is the blood pressure of the car, and the level of tire pressure plays a crucial role in the performance and power of the car. 2. Hazards of excessive tire pressure: The friction and adhesion of the tire will decrease, affecting braking performance; it can cause steering wheel vibration and deviation, reducing driving comfort.

The scrapping period for semi-trailer tractors is 10 years, which can be extended, but not exceeding 5 years. 7. The scrapping period for low-speed trucks is 9 years, which can be extended, but not exceeding 3 years.

Why does the car reversing radar keep beeping?

Reasons why the car reversing radar keeps beeping: 1. The reversing radar sensor is dirty, just wipe it clean; 2. The reversing radar alarm circuit is faulty, check if there is any abnormality in the alarm circuit; 3. The reversing radar sensor or controller is malfunctioning, and the faulty components need to be replaced. The reversing radar is a safety assistance device for parking or reversing the car. It can inform the driver about surrounding obstacles through sound or more intuitive display, eliminating the troubles caused by the driver's need to look around when parking, reversing, or starting the vehicle, and helping the driver to overcome blind spots and blurred vision.

What tires are best for the Nissan Bluebird?

Nissan Bluebird uses Bridgestone Potenza sports tires with a size of 205/50 R17. Below is an introduction to automotive tire-related information: Tire functions: Support the entire weight of the vehicle, bear the load of the car, transmit traction and braking torque, ensure the adhesion between the wheels and the road surface; reduce and absorb vibrations and impacts during driving, prevent severe vibrations and early damage to automotive components, adapt to the high-speed performance of the vehicle and reduce driving noise, ensuring safety, handling stability, comfort, and fuel economy. Tire usage precautions: Enhance awareness of tire safety by frequently checking tires. Before driving on highways, conduct thorough and detailed inspections; in addition to tire pressure, observe whether there are cracks on the tire sidewalls and the wear condition of the tread, and promptly eliminate any potential hazards; regularly adjust wheel balance if it exceeds the standard.

Can You Still Drive When Pressure Loss is Detected?

You can still drive when pressure loss is detected. Generally, the tire pressure monitoring system will alert the driver only when the tire pressure drops to the minimum limit. However, if you don't have access to an air pump, you can still drive the vehicle to a nearby repair shop or 4S dealership to refill the tires. The tire pressure monitoring system in the car is designed to monitor the tire pressure in real time. Some car models do not have a tire pressure monitoring function and cannot display the tire pressure values in real time, but most are equipped with a tire pressure warning system. If the pressure in one or more tires changes, the warning system will alert the driver.
