How many points are deducted for an illegal U-turn?

Making a U-turn at a no-U-turn intersection results in a 12-point deduction. According to Article 49 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China": Motor vehicles are not allowed to make U-turns at locations with no-U-turn or no-left-turn signs or markings, as well as at railway crossings, pedestrian crossings, bridges, sharp curves, steep slopes, tunnels, or sections prone to danger. Motor vehicles may make U-turns at locations without no-U-turn or no-left-turn signs or markings, but must not obstruct the normal passage of other vehicles and pedestrians. Correct U-turn procedures: At a regular intersection without a waiting area, motor vehicles should make a U-turn when the left-turn signal is green. At a regular intersection with a waiting area, motor vehicles should proceed straight into the waiting area when the straight signal is green, and make a U-turn when the left-turn signal turns green. At an intersection with a U-turn gap, motor vehicles may make a U-turn when the traffic light is red, provided it does not affect the normal passage of vehicles from other directions, and must yield to pedestrians. At an intersection with a U-turn gap, motor vehicles should proceed straight into the waiting area when the straight signal is green, and make a U-turn when the left-turn signal turns green. On a road section with a U-turn gap, motor vehicles may make a U-turn if it does not affect the normal passage of oncoming traffic. At an intersection with a dedicated U-turn lane, motor vehicles should use the U-turn lane and make a U-turn when the U-turn signal is green, yielding to pedestrians. Important notes: U-turns are prohibited when the U-turn signal is red, at intersections without left turns, on zebra crossings and pedestrian crossings, and at intersections where the centerline of the road is solid.

What are the reasons for the yellow wrench light to come on?

The yellow wrench light on the car dashboard is a maintenance reminder light. When it lights up, it indicates that the car needs maintenance. The car maintenance reminder light is not due to any fault but serves as a reminder only. The relevant introduction to car maintenance is as follows: Introduction to Car Maintenance: Car maintenance, also known as car servicing, refers to the regular preventive work of inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car. Purpose of Car Maintenance: To keep the car clean and tidy, maintain normal technical conditions, eliminate potential hazards, prevent faults, and extend the service life. Types of Car Maintenance: Regular maintenance is divided into three aspects: body maintenance, interior maintenance, and body refurbishment.

Is Engine Oil Conductive?

Pure engine oil is basically non-conductive because insulators have poor conductivity and are prone to generate static electricity during friction. Reasons why oil is non-conductive: Engine oil is an insulator and contains almost no freely moving electric charges. It inherently lacks free electrons and free ions, as most free charges (including free electrons and free ions) are bound by atomic nuclei, thus preventing conductivity. However, these insulators can become conductors under certain specific conditions (becoming conductive due to reduced binding capacity of atomic nuclei). Precautions for using engine oil: Specialized gasoline engine oil should not be used as a substitute for diesel engine oil to avoid accelerating wear in diesel engines. Gasoline engine oil and diesel engine oil should, in principle, be used separately. Substitution or universal use within the specified grade range is only permissible when the automobile manufacturer provides substitution instructions or explicitly labels the oil as suitable for both gasoline and diesel engines.

What is the typical discount for a one-year-old test drive vehicle?

Under normal circumstances, the discount for test drive vehicles is around 10% to 20% off, but there is no absolute standard. The actual discount depends on the mileage and condition of the test drive vehicle. Introduction to Test Drive Vehicles: Test drive vehicles are cars provided by 4S stores or car dealerships for potential buyers to test drive. Generally, because test drivers will test various performance aspects of the vehicle, including aggressive acceleration and braking—behaviors not suitable for the break-in period—test drive vehicles are sold at a discount. Buyers should carefully consider their own situation before purchasing a test drive vehicle. Risks of Buying a Test Drive Vehicle: It is generally not recommended for novice buyers to purchase test drive vehicles. Although test drive vehicles may have low mileage, both test drivers and accompanying staff tend to treat these vehicles roughly since they are company cars.

What is the voltage of five batteries?

An electric vehicle with 5 batteries is 60 volts. Because one battery in an electric vehicle is 12 volts, 4 batteries would be 48 volts, and 6 batteries would be 72 volts. Battery voltage of electric vehicles: The higher the battery voltage, the larger the capacity, and the greater the range. Under the same voltage, a battery with a larger capacity has more power. With the same capacity, a battery with higher voltage has stronger operational capability than one with lower voltage. Methods to extend battery life: Avoid storing in a discharged state: A discharged state refers to when the battery is not charged promptly after use, leading to insufficient charging and reduced battery capacity. The longer the battery remains idle in a discharged state, the more severe the damage. When the battery is not in use, it should be charged once a month to extend its lifespan.

What are the consequences of driving 10 kilometers with the handbrake on?

Driving 10 kilometers with the handbrake on can cause damage to the handbrake system and also affect the tires. After driving five kilometers with the handbrake on, the temperature of the rear wheel rims becomes very high because the brake transfers heat to the rims. Driving with the handbrake on causes significant damage to the handbrake system. It is recommended to always remember to release the handbrake when driving normally. The relevant introduction to the handbrake is as follows: Definition of Handbrake: The professional term for the handbrake is auxiliary brake. Unlike the principle of the main brake, it uses a steel cable connected to the rear brake shoes to brake the car. Consequences of Long-term Use of Handbrake: Long-term use of the handbrake can cause plastic deformation of the steel cable. Since this deformation is irreversible, long-term use will reduce its effectiveness, and the handbrake's travel distance will also increase. The handbrake is also equipped with a return spring. When the handbrake is engaged, the spring is stretched, and when the handbrake is released, the spring returns to its original length. Long-term use of the handbrake can also cause corresponding deformation of the spring.
