What to Do When Encountering Illegally Parked Cars Blocking the Way?

Is hitting a guardrail and leaving considered hit-and-run?

Hitting a guardrail and leaving is considered hit-and-run. If you hit a guardrail and leave the scene without reporting it to the police, it constitutes a traffic hit-and-run offense. The penalties range from deducting 12 points, a fine of 2,000 yuan, and detention for up to 15 days in minor cases, to revocation of the motor vehicle driver's license with a lifetime ban on reapplying, or even imprisonment in severe cases. Knocking down a guardrail damages road facilities and poses safety hazards by affecting the traffic flow of other vehicles. Traffic hit-and-run refers to the act of fleeing the scene after a traffic accident to evade legal consequences. Eight scenarios, including leaving the scene believing oneself not at fault, failing to wait for handling after reporting the accident, or abandoning the vehicle and later returning, are identified as traffic hit-and-run.

What Causes the Engine Malfunction Light to Sometimes Illuminate in a Car?

The reasons why the engine malfunction light sometimes illuminates in a car include: 1. Poor combustion of the air-fuel mixture. Issues such as faulty spark plugs, malfunctioning ignition coils, fuel pump failure, or clogged fuel lines can lead to poor combustion of the engine's air-fuel mixture. Poor combustion results in engine carbon buildup or knocking problems, which are detected by the engine's oxygen sensor and reported to the ECU, triggering the malfunction light as a warning; 2. Poor engine maintenance is the most common cause of the engine malfunction light illuminating; 3. Sensor problems, including those related to coolant temperature, crankshaft position, air flow, intake air temperature, and oxygen sensors. When these sensors are damaged, have poor connections, or experience signal interruptions, the car's ECU cannot accurately obtain engine data, causing the engine malfunction light to illuminate; 4. Fuel quality issues. The fuel added to a car 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 oil to use. If the owner does not follow these recommendations, prolonged use can lead to engine wear and trigger the malfunction light.

Differences Between Supercharging and Turbocharging

The differences between supercharging and turbocharging are: 1. Different methods: Supercharging is directly connected to the engine output via a belt, and the moment the engine starts, the supercharger begins transmitting power; turbocharging is driven by the engine's exhaust gases to spin the turbine. 2. Different rotational speeds: Superchargers rotate relatively quickly; turbochargers spin slowly, and their boosting effect is not immediately apparent—they need the engine to reach a certain RPM before they start working effectively. 3. Different linearity in power output: The power source of a supercharger comes from the engine's output, which places a burden on the engine. Small-displacement engines generally do not use supercharging; turbocharging is often installed on small-displacement engines to achieve the goal of high power output from a small displacement.

Can I apply for an A3 driver's license?

Yes, you can. To apply for an A3 driver's license, you must be at least 21 years old or have held any driver's license for at least one year without any full-point demerit records, and you need to register for training in your registered residence location. Below is relevant information about the A3 driver's license: 1. Physical requirements for the license: Height - Applicants for large buses, tractors, city buses, large trucks, or trolleybuses must be at least 155 cm tall. Applicants for medium-sized buses must be at least 150 cm tall. Vision - Applicants for large buses, tractors, city buses, medium-sized buses, large trucks, trolleybuses, or trams must have uncorrected or corrected visual acuity of at least 5.0 on the logarithmic visual acuity chart. For other vehicle types, the requirement is at least 4.9. Applicants with monocular vision impairment can apply for small cars, small automatic transmission cars, low-speed trucks, three-wheeled cars, or small automatic transmission passenger cars for the disabled if their better eye has uncorrected or corrected visual acuity of at least 5.0 and a horizontal field of vision of at least 150 degrees. Color vision - No red-green color blindness. Hearing - Must be able to discern the direction of sound from a tuning fork 50 cm away in each ear. Applicants with hearing impairment who meet the above criteria with hearing aids can apply for small cars or small automatic transmission cars. Upper limbs - Both thumbs must be intact, and each hand must have at least three other fingers intact with normal movement. Applicants with missing fingertip segments or a missing right thumb can apply for small cars or small automatic transmission cars. Lower limbs - Both legs must be intact with normal movement, and the length difference should not exceed 5 cm. Applicants with a missing or non-functional left leg can apply for small automatic transmission cars. Those with missing or non-functional right or both legs but can sit independently can apply for small automatic transmission passenger cars for the disabled. Trunk and neck - No movement disorders. 2. Vehicles allowed with an A3 license: The A3 license is primarily for driving city buses but is not limited to them. According to regulations, holders of an A3 license can also drive vehicles under the C1 category, such as small cars, small automatic transmission cars, low-speed trucks, and three-wheeled cars. Although city buses are over six meters long and carry more than 20 passengers, they are not equivalent to large coaches like tourist buses. Therefore, an A3 license alone does not permit driving large coaches, whereas an A1 license allows driving both large coaches and city buses.

How to Turn on the External Air Circulation in a Mercedes-Benz?

Method to activate external air circulation in Mercedes-Benz: First press the internal circulation button - the illuminated indicator signifies internal circulation. External circulation is engaged only when the indicator turns off. Therefore, the external circulation function shares the same button as internal circulation, which serves multiple purposes: 1. Briefly press the internal circulation button (indicator illuminates) to activate internal circulation; 2. Briefly press it again (indicator turns off) to switch to external circulation; 3. Long-press the button to automatically close/open all windows - particularly useful when encountering sudden smoke, dust, or polluted road conditions while driving with windows open. After enabling external circulation, the air intake located at the firewall is opened by the climate control system. The blower then draws outside air through the microfilters into the evaporator's dual heat exchangers. Conditioned air is subsequently discharged through the vents. Note: Certain Mercedes models automatically revert to external circulation after 5-10 minutes of forced internal circulation to maintain air quality and sufficient oxygen levels, explaining why outside air may still enter during internal circulation mode.

What is the purpose of a bumper?

A bumper is an important safety device designed to absorb and mitigate external impacts, protecting the front and rear parts of the vehicle body. Typically located at the front and rear ends of the car, bumpers are mostly made of highly elastic materials such as plastic or resin, with some containing materials like silk fibers. The primary function of a bumper is to reduce the impact of minor collisions on the vehicle, and they are relatively easy to replace if damaged. Modern front and rear bumpers are made of plastic, commonly referred to as plastic bumpers, but not ordinary plastic. Generally, bumpers are made of ABS engineering plastic, utilizing computer-controlled painting processes with multiple layers of coating to achieve matte or mirror-like finishes. These bumpers do not fade or rust, fitting more seamlessly with the vehicle body while enhancing the texture of the front and rear aesthetics, all while protecting the car.
