How to Make a U-Turn at a Crosswalk?

Making a U-turn before a crosswalk requires different approaches depending on the situation. Here are the specific details: 1. If there is a double solid line on the left side of the vehicle, you must cross the crosswalk and wait for the green light before making a U-turn in front of the crosswalk. Otherwise, it will be considered running a red light. 2. If there is a dashed line on the left side of the vehicle, at such an intersection, when the left-turn signal is red and there are no vehicles waiting to turn left ahead, you can make a U-turn provided it does not affect the normal passage of vehicles from other directions. 3. In the absence of any signs or markings prohibiting a U-turn, you can make a U-turn in the left-turn lane.

How Should Beginners Learn to Reverse a Car?

Methods for beginners to learn reversing are as follows: 1. Reverse using rearview mirrors: Use the right rearview mirror to judge the distance between the rear wheel and the curb, determining the steering wheel's turning amplitude. 2. Reverse by looking through the rear window: Hold the upper edge of the steering wheel with your left hand, turn your body to the right, and observe the rear by looking through the rear window while reversing. 3. Reverse by looking sideways: Hold the upper end of the steering wheel with your right hand, lean your upper body out of the driver's compartment to the left, turn your head to look back, and observe the situation while reversing. Below are the key points about reversing: 1. Maintain the correct posture when reversing, choose a reversing target to control the steering wheel's turning degree, ensuring accuracy during reversing. 2. When selecting a target, choose one that is obvious, easy to observe, secure, not easily hit by the vehicle, and has a contrasting angle. 3. While reversing, clearly see the surrounding situation, stabilize the throttle, control the speed to avoid sudden changes, and always be prepared to stop. 4. The steering wheel operation is the same as when moving forward; if the car deviates to the left (right), immediately turn slightly to the right (left), and straighten the steering wheel once the rear is aligned.

What are the precautions for warming up the car in winter?

Here are the precautions for warming up the car in winter: 1. Warm up smoothly and accelerate gradually. 2. Drive at low RPM and avoid aggressive driving behaviors such as deep throttle, sudden acceleration, sudden braking, etc. Here are the methods for warming up the car in winter: 1. Start driving 30 seconds to one minute after starting the engine. 2. Maintain a low speed and avoid driving at high RPM; keep the engine speed around 2000 RPM. 3. Resume normal driving only after the engine temperature rises to the normal operating temperature. Here are the reasons for warming up the car in winter: 1. After the car has been parked overnight, the engine oil flows back to the oil pan at the bottom of the engine. Therefore, when starting the engine in the morning, the upper part of the engine is without oil and lacks lubrication. 2. It takes about 30 seconds after starting for the oil pump to circulate the oil to the parts that need lubrication the most, such as the pistons, connecting rods, and crankshaft.

Is a Car Produced 5 Months Ago Considered a Stock Vehicle?

Generally speaking, a car is considered a stock vehicle only if it has been produced for more than six months, so a car produced five months ago does not qualify. Here is some information about stock vehicles: 1. There is no clear legal definition for stock vehicles, and no relevant national laws or regulations specify them. However, in the automotive sales industry, the term "stock vehicle" does exist, generally referring to cars that have been in inventory for more than six months without being sold. 2. As a commodity, cars are large in size, expensive, and incur high storage costs. They also tie up a significant amount of dealers' capital. Therefore, dealers usually do not allow inventory vehicles to remain unsold for an extended period.

How to Clean Willow Catkins in the Car Radiator?

Here are the methods to clean willow catkins from the car radiator: 1. For external cleaning, use high-pressure air from an air pump to blow out debris from the gaps instead of washing with water; 2. For internal cleaning, use chemical methods to remove scale. Professional car radiator descaler can be used to clean the inside of the radiator without disassembly; 3. It can also be cleaned while the car is running. Follow the instructions carefully, directly pour the specialized scale remover into the car's water circulation system, let it soak, idle or drive for 20-30 minutes, then drain the descaler from the radiator and the system.

How Many Liters of Engine Oil Should Be Added to a Car?

Generally, about 4 liters of engine oil should be added to a car. The oil dipstick has upper and lower marks, and it's best to fill it to the middle of the marked line. For ordinary cars, 4 liters is sufficient, but the oil dipstick must be used. Insufficient oil can affect the lubrication system, but adding too much is not better either. Excessive oil can cause more oil to splash onto the cylinder walls, leading to oil burning and blue smoke emission. Under normal circumstances, the following four factors should be considered when choosing engine oil: 1. The selection of engine oil should be based on the requirements of the engine. It is unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. 2. Multi-grade oil should be preferred as it is economical, long-lasting, and efficient, providing better protection for the engine. Due to the characteristics of multi-grade oil, it may appear darker earlier and have lower oil pressure compared to regular oil, which is normal. 3. Some domestic brand oils are of quite good quality and are much cheaper than imported counterparts, so they can be used with confidence. There is no need to blindly pursue 'foreign oils.' 4. If the engine is in good condition and the seasonal temperature is low, using oil with lower viscosity is recommended to ensure smooth oil flow. In high-temperature seasons or when the engine is severely worn, choosing high-viscosity oil helps form an oil film and reduces engine wear.
