How to Make a U-turn at an Intersection Ahead While Driving a Motor Vehicle?

When making a U-turn at an intersection ahead while driving a motor vehicle, the methods vary depending on different situations, as follows: 1. U-turn in the left-turn lane requires crossing the pedestrian crossing: When the traffic light turns green at the intersection, you can make a U-turn in the left-turn lane, but you must cross the pedestrian crossing. 2. U-turn can be made directly if the inner side of the lane is a dashed line: If the inner side of the double yellow line left-turn lane is a dashed line, you can make a U-turn directly without regard to the traffic light, but you must not affect the oncoming traffic. 3. U-turn can be made at the dashed line if there is a yellow grid dashed line: If there is a yellow grid dashed line in the middle of the road, you can make a U-turn at the dashed line, but you must not stop inside the yellow grid. 4. U-turn can be made when the light turns green in the waiting area: At an intersection with a left-turn waiting area, enter the left-turn waiting area when the traffic light turns green. When the left-turn light turns green, you can make a U-turn.

Is it necessary to buy a safety seat for babies?

It is necessary to buy a safety seat for babies because the seat belts in the car are specifically designed for adults and are only suitable for people over 145 cm tall. Below are the four stages of correct use of the child restraint system: 1. First stage (rear-facing child safety seat): Infants and children aged 1 year and under (weighing 0-13 kg) should use a rear-facing child car safety seat. This seat has multiple layers of protection, including a backrest, cushion, and neck safety pillow, which maximizes the absorption of impact force. 2. Second stage (forward-facing child safety seat): Children aged 1-4 years (weighing 9-18 kg) should switch to a forward-facing child seat, and the harness inside the seat needs to properly restrain the child. 3. Third stage (high-back or backless booster seat): Children aged 4-12 years (weighing 15-36 kg, under 145 cm tall) should use a booster seat, ensuring that the shoulder belt of the seat belt rests on the child's shoulder and the lap belt is on the child's hips. 4. Fourth stage (adult seat belt): Children aged 12 and above (weighing over 36 kg, 145 cm and taller) should use the adult seat belt, ensuring that the belt's position is on the child's shoulder and hips. The child should sit with their back against the seat, feet flat on the floor, and maintain this posture throughout the journey.

Which road surface is most prone to skidding?

Road surfaces that have just started to get wet from rain are most prone to skidding. Below is extended information about road surface classifications: 1. Rigid pavement: Under traffic loads, it can produce slab action with high flexural strength and very small deflection deformation, exhibiting significant rigidity. Its failure depends on the ultimate flexural strength. The main representative of rigid pavement is cement concrete pavement, including cement concrete pavements with dowel bars at joints, without dowel bars, and with reinforced steel mesh. 2. Flexible pavement: It undergoes relatively large deflection deformation under load with low flexural strength, and accumulates deformation under repeated loads. Its failure depends on the ultimate vertical deformation and flexural strain. The main representatives of flexible pavement are various asphalt surfaces, including asphalt concrete (referred to as concrete after compaction in British standards) surfaces, asphalt macadam surfaces, and asphalt penetration crushed (gravel) stone surfaces. 3. Semi-rigid pavement: Some pavement materials exhibit flexible pavement characteristics in the early construction stage and nearly rigid pavement characteristics in the later stage. Such pavements are called semi-rigid pavements. Examples include pavements constructed with lime-stabilized soil, cement-stabilized soil, lime-fly ash, and lime-slag materials.

What is the difference between 98 and 95?

Compared with 95 gasoline, 98 gasoline has greater technical difficulty, higher processing costs, and a higher selling price. The following is extended information about gasoline characteristics: 1. Volatility: Refers to the ease with which gasoline evaporates in the carburetor. The volatility of gasoline is comprehensively evaluated by three indicators: distillation range, vapor pressure, and gas-liquid ratio: (1) Distillation range. Refers to the temperature range of gasoline fractions from the initial boiling point to the final boiling point; (2) Vapor pressure. It is an indicator that reflects the tendency of gasoline to cause vapor lock in the fuel system and the difficulty of starting the engine; (3) Gas-liquid ratio. Refers to the ratio of vapor volume to liquid volume in a standard instrument under specified temperature and atmospheric pressure. 2. Anti-knock performance: Refers to the ability of gasoline to resist knocking combustion under various operating conditions. The anti-knock performance of automotive gasoline is expressed by the octane number. The higher the octane number, the better the anti-knock performance. The octane number of gasoline is measured by an octane engine, and the grade of gasoline is classified according to the octane number. 3. Stability: Refers to the stability of gasoline when stored for a long time under natural conditions. It is characterized by gum content, induction period, and iodine value.

How many days after enrolling in a driving school can you make an appointment?

After successfully enrolling in a driving school, you can schedule an exam in about a week. Notes for online driving test appointment: 1. Note 1: Training must be completed to qualify for the driving test appointment. The traffic management department states that the student's exam permit must be valid, the training for the subject to be tested must be completed and the course must be concluded before an appointment can be made. Cheating on the exam will result in a one-year waiting period before another appointment can be made. The online system will automatically review the student's qualifications, and unqualified applications will be rejected. 2. Note 2: Before making an appointment, ensure that the required driving practice hours have been completed. Otherwise, during the online appointment process, if the comparison of identity information reveals insufficient practice hours, the appointment will be automatically canceled. 3. Note 3: Students must know in advance the appointment time for their driving school's group and schedule an online appointment 20 days before this time. After a successful appointment, promptly contact the driving school to pay fees and print the exam permit. Additionally, the number of online slots is calculated based on the exam capacity of each test center and the actual number of driving school vehicles, which may change monthly. Students should regularly check the official Weibo of the Vehicle Management Office for updates.

What does zone mean in a car?

Zone in a car refers to the air conditioning temperature zoning control, which allows setting different temperatures in different areas of the car to meet various needs. The function of air conditioning temperature zoning control: It provides a comfortable environment for drivers and passengers by setting different air conditioning temperatures and airflow levels for different areas in the car, catering to passengers with varying temperature preferences. How air conditioning temperature zoning control works: It increases the number of air vents, divides the air ducts into finer and more sections, and delivers air through several mixing vents to different duct zones, with each zone controlled by multiple independent controllers. The air conditioning temperature zoning control function is located in the car's control area.
