Can You Make a U-Turn at an Intersection Where Left Turns Are Prohibited?

U-turns are not allowed at intersections where left turns are prohibited. When driving a motor vehicle, you must not make a U-turn at locations with no U-turn or no left turn signs or markings, as well as at railway crossings, pedestrian crosswalks, bridges, sharp curves, steep slopes, tunnels, or sections of road prone to danger. Violating this rule will result in a three-point penalty on your driver's license. Circumstances under which U-turns are permitted are as follows: Presence of U-turn traffic lights or signs: When there is a U-turn traffic light at an intersection, you can make a U-turn when the U-turn light is green. If there is a U-turn sign or a lane marking indicating U-turns is allowed, you can make a U-turn after ensuring the safety of yourself and others. No U-turn signs but left turns are allowed (no prohibition of U-turn signs or markings): Vehicles can make a U-turn at intersections where left turns are permitted and there are no signs or markings prohibiting U-turns. It is important to note that vehicles must proceed according to the left-turn signal without interfering with the normal flow of other vehicles. If making a U-turn at an intersection with a left-turn waiting area, you can enter the left-turn waiting area when the straight signal is green and wait until the left-turn signal turns green to make the U-turn. U-turns are allowed at dashed lines: Whether it is a white dashed line or a yellow dashed line, U-turns are permitted. In the case of double yellow lines (one solid and one dashed), check if your side is the dashed line—if it is, you can make a U-turn safely; if it is the solid line, U-turns are not allowed.

What to Do If You Accidentally Add One Liter of Diesel to a Gasoline Car?

Here are the steps to handle the situation of mistakenly adding diesel to a gasoline car: 1. After realizing the wrong fuel has been added, do not attempt to start the engine to prevent diesel from entering the fuel system. Then, tow the car to a 4S shop or repair shop to drain the diesel completely and refill with gasoline. If the amount of diesel added does not exceed 5-10% of the tank's capacity and is detected promptly, there should be no major issues—simply refill with gasoline, and it won’t cause any significant impact. 2. In reality, most drivers who add the wrong fuel don’t notice it immediately. Instead, they realize it only after driving for a while when the car shows abnormal symptoms such as severe vibration, poor acceleration, or even stalling. In such cases, call for roadside assistance immediately. At the repair shop, besides draining the diesel, the fuel system needs to be cleaned, the gasoline filter replaced, and a comprehensive inspection performed. In most cases, the engine will stall before severe knocking can cause catastrophic damage, so situations like the one shown in the image below are generally rare. Here’s why diesel should not be added to a gasoline engine: 1. Diesel has a lower auto-ignition point, so diesel engines use compression ignition. They don’t require spark plugs; instead, they compress air to raise the temperature to the diesel’s ignition point, then inject diesel, which ignites spontaneously. 2. Diesel engines don’t have spark plugs. If diesel enters a gasoline engine, it starts burning violently before the spark plugs ignite, causing abnormal pressure in the combustion chamber—commonly known as knocking. 3. Additionally, the fuel injector pressure in gasoline engines is much lower than in diesel engines. When diesel is added to a gasoline engine, it cannot be fully atomized, leading to incomplete combustion. This results in a lack of engine power, unresponsive acceleration, severe carbon buildup, and clogged fuel injectors.

How to Solve the Engine Yellow Light Issue?

Here are the methods to address the engine yellow light issue: 1. When the engine fault light on the dashboard illuminates, you can try starting and turning off the vehicle three times in a row, or disconnect the negative terminal of the engine battery, wait for 30 seconds, reconnect it, and then attempt to start the engine. After performing the above steps, check if the engine fault light on the dashboard is still on. 2. It's important to note that when the engine fault light on the dashboard illuminates, it usually cannot be manually reset. Typically, you need to visit a 4S shop to use a fault detection device for troubleshooting before it can be reset. The above methods are only applicable for false fault phenomena in the engine. If they prove ineffective, please visit a specialized repair shop for inspection and reset. Reasons for the engine yellow light on the dashboard include: 1. Sensor issues: The sensors mentioned here include those for coolant temperature, crankshaft position, air flow, intake temperature, oxygen, etc. When these sensors are damaged, have poor contact, or experience signal interruptions, the vehicle's ECU cannot accurately obtain engine data, which can cause the engine fault light to illuminate. 2. Maintenance issues: Poor engine maintenance is the most common cause of the engine fault light illuminating. Vehicles have specific maintenance cycles. If the owner does not adhere to the maintenance schedule and has poor driving habits, it will increase the operational burden on the engine, ultimately triggering the fault light as a reminder for maintenance. 3. Fuel quality issues: Fuel quality includes both fuel and engine oil. The fuel used in cars usually has a specific grade, and engine oil can be semi-synthetic or fully synthetic. Manufacturers generally recommend which grade of fuel and type of engine oil to use. If the owner does not follow these recommendations, prolonged use can lead to engine wear, causing the fault light to illuminate.

How long does it take for a revoked driver's license status to be cleared?

Driver's license revocation status will be cleared after 15 days. Participate in a 7-day study of road traffic safety laws, regulations, and related knowledge. Process for lifting driver's license revocation status: Present the education notice issued by the public security traffic management department, and bring your ID card, driver's license, or temporary driver's license revocation certificate. Attend the full-score education study on time, and after completing the study, receive the "Exam Reservation Certificate" for Subject 1; bring your ID card and the "Exam Reservation Certificate" to attend the Subject 1 exam on time; after passing the exam, present the driver's exam pass notice to the public security traffic management department to retrieve your driver's license. Regulations on driver's license point deductions: Review education differs from full-score education. If a motor vehicle driver scores 12 points or more twice in one scoring cycle or accumulates 24 points or more, the vehicle management office must conduct a road driving skills test within 10 days after the driver passes the road traffic safety laws, regulations, and related knowledge exam. Driving a motor vehicle that does not match the permitted vehicle type, driving under the influence of alcohol or while intoxicated, driving a highway passenger vehicle overloaded by 20% or more, fleeing the scene of a traffic accident without constituting a crime, using forged or altered motor vehicle license plates, registration certificates, or driver's licenses, or using other motor vehicle license plates or registration certificates, or performing traffic violations such as reversing, driving against traffic, or making U-turns across the central divider on highways will result in a one-time deduction of 12 points.

What Are the Hazards of Flood-Damaged Cars?

Flood-damaged cars can suffer from damaged circuits, electrical components, precision instruments, insulation and soundproofing materials, transmission damage, and engine failure. After being soaked in water, the interior can develop mold spots that damage fabric and genuine leather materials. Definition of Flood-Damaged Cars: Flood-damaged cars refer to vehicles that have been submerged in water. They are categorized into three levels based on the severity of damage: the first level involves water exceeding the wheel height and entering the interior; the second level involves water exceeding the dashboard; the third level involves water submerging the roof. Among these, the first level is the most common and less hazardous compared to the latter two, while the latter two—where water exceeds the center console or submerges the entire vehicle—pose greater long-term risks. Flood-damaged cars often retain sand and grit that cannot be completely removed, which may remain in gears or belts, leading to premature wear, rusting of body components, shortened lifespan, and reduced safety performance. Even after repairs, flood-damaged cars may experience sudden issues, such as engine stalling during high-speed driving or airbags failing to deploy when needed or deploying unexpectedly. How to Identify Flood-Damaged Cars: When purchasing a car, be wary of unusually low prices for seemingly new vehicles. Check if the interior has been altered or replaced. Inspect screws and internal components for rust, and look for mud residues under the carpets, in the air vents, or within the engine compartment.
