At which intersections are U-turns not allowed?

U-turns are prohibited at intersections with 'No U-turn' or 'No Left Turn' signs: If there is a no U-turn sign, then U-turns are not allowed at that intersection. The action of making a U-turn is an extension of a left turn, so if there is a no left turn sign at an intersection, U-turns are also prohibited there. Other situations where U-turns are prohibited are as follows: U-turns are not allowed from the second left-turn lane: When a vehicle is in the second left-turn lane, it cannot make a U-turn. In the absence of any signs indicating otherwise, vehicles can only make U-turns from the innermost left-turn lane. U-turns are prohibited at solid yellow lines: U-turns are not allowed at solid yellow lines. Even if there is a sign permitting U-turns, you must wait for the green light and cross the stop line to make the turn. U-turns are prohibited on highways: Crossing the central divider to make a U-turn on a highway is illegal and will result in a fine of 200 yuan and 12 demerit points. If you miss an exit on the highway, continue to the next exit to leave the highway, and never attempt an illegal U-turn.

What are the disadvantages of dual-engine cars?

The disadvantages of hybrid cars include high prices, difficult maintenance, etc. Details are as follows: High price: The price for the same displacement is 40% higher. For a standard 1.8L model, ordinary cars cost around 150,000 yuan, while hybrid cars cost around 210,000 yuan. The extra 60,000 yuan could cover fuel costs for ten years. Currently, with low oil prices, the advantage is not yet obvious. Difficult maintenance: Currently, the patent technology is still held by a few major foreign companies, and only large cities have the conditions for repairs. Some parts are unique to hybrid cars and cannot be shared with ordinary cars, such as the wheel hubs. Smaller space and heavier weight: An additional set of batteries and electric motors take up a lot of space and increase weight. On long-distance trips, the gasoline engine works just like in an ordinary car, but the hybrid carries an extra set of electric motors. In the city, the electric motor is mainly used, but the hybrid carries an additional gasoline engine compared to pure electric vehicles. These loads consume energy. Operational drawbacks: You need to monitor the battery level, otherwise, insufficient charge can make starting difficult; you also need to pay attention to turning off the electric motor when parking, and it cannot be turned off with a single button.

What does 'No Deductible' mean in car insurance?

Car No Deductible Insurance is a type of commercial insurance, with the full name being 'No Deductible Rate Special Clause'. It is an additional coverage that requires a 'main insurance' policy to be purchased and cannot be bought separately. The detailed introduction is as follows: Additional Deductible Rate: Auto insurance clauses stipulate that the claim scope of No Deductible Insurance does not include additional deductible rates. Typically, the conditions for implementing additional deductible rates include multiple claims, claims by non-designated drivers, violations of safety loading regulations, or increased deductible rates due to the lack of claim documentation by the car owner during theft insurance claims. Third-Party Accident Not Found: Insurance companies set a separate absolute deductible rate, usually 30% or 50%, for car damage accidents where the third party cannot be found. However, such deductible rates are not covered under the No Deductible Insurance claim scope. Difficulty in Determining Accident Liability: Sometimes, during the process of handling a traffic accident through mutual agreement, car owners fail to take accident photos or mark the tire tracks before moving their vehicles away from the scene, making it difficult for insurance companies to objectively and accurately determine liability. Alternatively, if one car owner feels the damage is minor and leaves the scene, preventing the other owner from assisting the insurance company in inspecting both damaged vehicles, the insurance company will apply a separate deductible rate as the basis for the claim.

What are the reasons for a car's air conditioning suddenly not cooling?

Introduction to the reasons why a car's air conditioning is not cooling: 1. Insufficient or too little refrigerant. A common reason for a car's air conditioning not cooling is insufficient or too little refrigerant, which is likely caused by minor leaks. 2. Too much refrigerant. There are specific requirements for the proportion of refrigerant in the air conditioning system. If the proportion is too high, it can affect heat dissipation. 3. Loose drive belt of the car's air conditioning compressor. Car cooling relies on refrigerant, and refrigerant transmission depends on the air conditioning compressor. The drive belt is an important moving part that drives the compressor. If the drive belt is loose, the compressor may slip during operation, leading to reduced transmission efficiency, decreased compressor speed, and reduced refrigerant delivery, resulting in the air conditioning not cooling. If the compressor drive belt is too loose, it should be tightened. If it cannot be turned by hand, it indicates the belt is too tight and should be slightly loosened. 4. Substandard refrigerant and refrigeration oil. Excessive impurities in the refrigerant and refrigeration oil can clog the car's air conditioning filter, causing the air conditioning not to cool. This increases resistance and reduces the flow of refrigerant to the expansion valve, leading to insufficient cooling capacity. 5. Moisture infiltration in the refrigeration system. If moisture enters the car's air conditioning refrigeration system, it can cause insufficient cooling or no cooling at all.

What Does Automatic Transmission Fluid Inspection Include?

Automatic transmission fluid inspection should include checking the fluid level, fluid quality, and potential leakage points. During the transmission fluid inspection process, it is crucial to maintain cleanliness to prevent dust particles from entering the transmission, which could lead to premature transmission failure. If abnormal transmission fluid levels are observed, begin with a simple visual inspection to identify obvious leaks or other issues. It is recommended to take the vehicle to an authorized after-sales service center for professional inspection and troubleshooting. Here are the relevant details: 1. Low automatic transmission fluid level: This condition may cause the oil pump to draw in air, resulting in aerated fluid that reduces oil pressure and slows pipeline pressure buildup. It leads to inadequate lubrication of planetary gear systems, clutch and brake slippage, and deteriorated acceleration performance. Low fluid levels are typically caused by external leaks. The cause should be identified and fluid should be replenished according to specifications. 2. High automatic transmission fluid level: Rotating planetary gears can agitate the fluid, causing air entrainment and foam formation. Overfilled fluid may also overheat and oxidize, forming sludge that affects the normal operation of valves, clutches, and brake servo cylinders. Excessively high fluid levels may cause fluid to spray from the filler tube or vent pipe, potentially leading to engine compartment fires. High fluid levels are usually caused by overfilling. The solution is to extract excess fluid through the filler tube or drain the surplus through the drain plug.

Why is the Lexus reversing radar not beeping?

There may be three reasons: whether the radar host wire is loose; the buzzer is damaged; or the wiring at the bumper is damaged. Here are the detailed explanations: 1. Whether the radar host wire is loose: If you find that the reversing radar is not beeping, first check whether the power cord of the host is properly connected and whether there is current; then check whether the radar host wire is loose. If neither of these is the problem, the issue may lie with the radar itself. 2. Buzzer damage: If the problem is confirmed to be with the reversing radar, the first possibility to consider is that the buzzer is damaged. In this case, you need to purchase and install a new buzzer; also, recall whether your car has undergone any recent modifications. If so, it is possible that the reversing radar wiring was damaged during the modification process. In this case, you need to take the car to the original repair shop or a 4S store for inspection. 3. Wiring damage at the bumper: When you find that the reversing radar is not beeping, you can also check whether the wiring connection at the bumper is intact, then check whether the reversing light is on when the reverse gear is engaged. If it is not on, check whether the connection switch of the reversing light is broken. Then, you can check whether the computer displays any fault codes. If none of these is the problem, then check whether the reversing radar itself is malfunctioning.
