Driving a motor vehicle is not allowed to overtake under the following circumstances: 1. When the vehicle in front is making a left turn, turning around, or overtaking; 2. When there is a possibility of meeting an oncoming vehicle; 3. When the vehicle in front is a police car, fire truck, ambulance, or engineering rescue vehicle performing emergency tasks; 4. When passing through areas such as railway crossings, intersections, narrow bridges, curves, steep slopes, tunnels, pedestrian crossings, or sections of urban roads with heavy traffic where overtaking conditions are not met. When overtaking, the motor vehicle should turn on the left turn signal in advance, switch between high and low beams, or sound the horn. On roads without a central dividing line or with only one motor vehicle lane in the same direction, when the vehicle in front receives an overtaking signal from the vehicle behind, it should reduce speed and move to the right to give way if conditions permit. The vehicle behind should overtake from the left side of the vehicle in front after confirming a sufficient safe distance, and after establishing the necessary safe distance from the overtaken vehicle, turn on the right turn signal and return to the original lane.

I just got my driver's license and always remind myself not to overtake recklessly while driving. The instructor repeatedly emphasized that overtaking is absolutely prohibited in certain situations, such as on roads with blind curves where visibility is too poor to see oncoming traffic, and overtaking could lead to a direct collision; or overtaking at the crest of a hill is also very dangerous due to obstructed sightlines; near intersections where pedestrians or vehicles are entering and exiting, overtaking can easily cause accidents; in tunnels where space is narrow, overtaking can lead to sideswipes or even rear-end collisions; and in rainy or foggy weather with low visibility, overtaking is not recommended. Once, I was in a hurry and attempted to overtake in the rain, only to enter a curve and nearly collide with an oncoming car. Since then, I've strictly adhered to the rules. Safe driving is no joke, and I always make sure the view is clear and the road conditions are safe before overtaking.

After driving for so many years, I've witnessed numerous accidents caused by reckless overtaking. I've summarized several situations where overtaking is absolutely not advisable: areas with limited visibility like sharp bends or steep slopes, where the risk is too high; sections with intersections, where traffic flow changes rapidly, making overtaking prone to collisions; tunnels and narrow bridges with limited space, where overtaking could lead to chain accidents; if the vehicle ahead is already overtaking, following suit (known as 'overtaking the overtaker') increases the likelihood of accidents; overtaking is even more dangerous when there's oncoming traffic, especially on narrow two-way roads. In rainy or snowy weather, slippery roads and poor visibility make overtaking risky. Driving isn't about racing; always assess the distance and speed before deciding. Be patient—you'll always reach your destination safely.

I drive to and from work every day and make it a habit to avoid risky situations, knowing there are conditions for overtaking. For example, you can't overtake on curves where visibility is blocked; the same goes for hilltops. In urban areas, overtaking is prohibited at intersections or school zones due to heavy traffic and chaotic roads, which can easily lead to accidents. Tunnels are cramped, making overtaking prone to scrapes and collisions. Attempting to overtake when there's oncoming traffic is reckless. Always obey traffic signs like double yellow lines or no-overtaking signals. Driving isn't about rushing to go faster—safety is more important than time.

Is Ethanol Gasoline Less Fuel-Efficient?

There is no definitive conclusion on whether ethanol gasoline is fuel-efficient. Research experiments conducted by the China Automotive Technology and Research Center indicate that the combustion heat value of ethanol is lower than that of gasoline. When blended at a 10% ratio, the heat value decreases by approximately 3.8% compared to pure gasoline. However, due to the increased oxygen content in the blended fuel, combustion becomes more complete, which can also increase heat output by 2.3%. Advantages of ethanol gasoline: High octane number and excellent anti-knock properties. Ethanol has an oxygen content as high as 34.7%. The use of ethanol gasoline in vehicles can effectively reduce tailpipe emissions and improve the energy structure. The production of fuel ethanol is resource-abundant and technologically mature. Disadvantages of ethanol gasoline: Fuel consumption may increase. Ethanol has a high latent heat of vaporization, which affects the formation of the air-fuel mixture and combustion speed, leading to reduced vehicle performance, fuel economy, and cold-start capability, and negatively impacting acceleration. During combustion, ethanol produces acetic acid, which can corrode automotive metals, especially copper. Ethanol is prone to absorbing water, and when the water content in ethanol gasoline exceeds standard limits, phase separation can easily occur.

What are the exam subjects in driving school?

The exam subjects in driving school include the following four subjects: Subject 1: Road traffic safety laws, regulations, and related knowledge exam; Subject 2: Field driving skills exam; Subject 3: Road driving skills exam; Subject 4: Safe and civilized driving common sense. Additional information: 1. Subject 1 and Subject 4 can be scheduled for exams without limit: Subject 1 and the safe and civilized driving common sense exam have no restrictions on the number of scheduling attempts. The safe and civilized driving common sense exam can only be taken after passing the Subject 3 road driving skills exam. Those who fail can directly apply for a retest, and the previously passed road driving skills exam scores remain valid. 2. If the exam is not passed, scheduling attempts cannot exceed 5 times: During the validity period of the driving skills permit, the number of scheduling attempts for Subject 2 and Subject 3 road driving skills exams cannot exceed five times each (i.e., ten exam opportunities in total). Those who still fail the fifth scheduled exam will have their other passed subjects' scores invalidated, and the student will need to retake the exams starting from Subject 1.

Can Ethanol Gasoline and Regular Gasoline Be Mixed?

Ethanol gasoline and regular gasoline can theoretically be mixed. However, due to varying fuel quality in different regions, there is still a possibility of impurities clogging the fuel injectors. Occasional mixing is acceptable, but for vehicles with over 30,000 kilometers, a thorough cleaning of the fuel tank and fuel system is recommended before using ethanol gasoline for the first time. Vehicles with less than 30,000 kilometers may not require cleaning. Even after cleaning, a small amount of impurities may still enter the fuel tank, so it is advisable to inspect and clean the vehicle after using the first tank of fuel. Regular Gasoline: Appears as a transparent liquid, flammable, with a distillation range of 30°C to 220°C. Its main components are C5-C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. Gasoline has a high octane number (anti-knock combustion performance) and is categorized by octane ratings such as 89#, 92#, 95#, and 98#. Ethanol Gasoline: A fuel processed from grains and various plant fibers. It is a new alternative energy source formed by mixing ethanol and regular gasoline in a certain ratio. According to China's national standards, ethanol gasoline is blended with 90% regular gasoline and 10% fuel ethanol. Currently, ethanol gasoline is prefixed with 'E,' such as E92#, E95#, and E98#.

How Does the Crawl System Work?

The working principle of the crawl system involves the intervention of the vehicle's computer to control the brakes, throttle, and torque output. It can also adjust torque based on road condition feedback and electronically distribute braking force to all four wheels, ultimately preventing wheel slip. The driver only needs to steer and adjust the speed via a knob on the dashboard, without pressing the accelerator or brake. Related information: The full name of the vehicle's crawl mode is the Low-Speed Cruise Driving Assist System, also known as the "Foolproof Off-Road System." This system is particularly useful for those with limited off-road experience, as it enables them to navigate challenging obstacles with the system's assistance. When in low-range four-wheel drive mode, activating the switch located on the right side of the gearshift lever engages the low-speed cruise assist mode, maintaining a speed between 1-5 km/h. Below the switch, there is a three-position knob that allows the driver to toggle between three different speed settings. When climbing steep slopes or driving on special terrains such as snowy or icy roads, rocky paths, or sandy areas, the low-speed cruise assist system automatically manages the engine and brakes to maintain a steady low speed, ensuring excellent and stable passability. During operation, the driver does not need to focus on the accelerator or brake and can even remove their foot from these pedals. By concentrating solely on the road ahead and steering, the driver can effortlessly traverse difficult terrain and even ascend to otherwise unattainable heights.
