Regulation: Vehicles must use the specified fuel grade; otherwise, engine problems may occur. Below is additional information on the differences between 95# and 92# gasoline: 1. Composition ratio: 95-octane gasoline contains 95% isooctane and 5% n-heptane, while 92-octane gasoline contains 92% isooctane and 8% n-heptane. 2. Anti-knock performance: 95-octane gasoline has higher anti-knock performance, whereas 92-octane gasoline has lower anti-knock performance.

Should You Use High Beam or Low Beam on the Highway at Night?

You should use high beam on the highway at night for the following reasons: 1. Vehicles travel at high speeds on the highway, and the distance between cars is relatively large. Low beams typically only illuminate about 30 meters ahead, making it difficult to assess road conditions further ahead. 2. Highways generally lack streetlights, so in case of emergencies ahead, it's challenging to react promptly. Driving at high speeds with low beams can be dangerous. However, not all sections of the highway require high beams. You should switch to low beams under the following circumstances: 1. When the distance to the vehicle ahead is relatively close, as high beams can impair the vision of the driver in front. 2. When overtaking or making a turn, you should use low beams along with turn signals to communicate your intentions to other drivers and provide a clear indication to those behind you during turns.

Is it mandatory for the owner to attend the annual vehicle inspection in person?

Vehicle annual inspection does not require the owner to attend in person. An authorized agent can handle the inspection by presenting the necessary proxy documentation and relevant vehicle materials. Below are the specific details regarding vehicle annual inspections: 1. Regulations and Purpose: The vehicle annual inspection refers to the annual examination of vehicles that have obtained official license plates and registration certificates, conducted according to the "Technical Conditions for Motor Vehicle Operation Safety." Its purpose is to inspect the main technical conditions of the vehicle, encourage enhanced maintenance, ensure the vehicle remains in good condition, and guarantee driving safety. 2. Principle of Proximity for Vehicle Inspection: For the annual inspection, vehicles only need to be taken to the vehicle management office or its designated inspection stations, adhering to the principle of proximity, which can be checked online. Starting from September 2018, vehicles can be inspected nationwide, allowing small cars, trucks, and medium-sized buses to be directly inspected in provinces other than where they are registered and to apply for inspection qualification marks.

Will a Hot Car Battery Explode While Charging?

Car battery heating up during charging will not cause an explosion. It is quite normal for a car battery to become hot while charging, as the electrolyte inside reaches a boiling state during the process. Therefore, when touched by hand, the battery naturally feels hot, and theoretically, there is no risk of explosion. However, if the battery overheats abnormally, it may lead to thermal runaway, causing the battery to swell. Such abnormal heating usually indicates severe sulfation of the car battery, which requires immediate repair. The method to repair battery sulfation is as follows: discharge the battery, pour out the original electrolyte, and then charge it with a low current while keeping the liquid temperature between 20 to 40 degrees Celsius. After completing the charging process, the sulfation issue will be resolved, and the battery capacity can generally recover to over 80%.

What to Do If You Drive in the Wrong Direction?

If you drive in the wrong direction on a regular road and there are no cameras nearby, simply make a U-turn to return to the correct direction. If you drive in the wrong direction on a highway, ensure safety first by moving your vehicle to the emergency lane, turning on the hazard lights, and placing the warning triangle at least 150 meters away from the direction of oncoming traffic. All passengers should move to a safe area outside the guardrail, and you should call the traffic police to report the situation and wait for their assistance. Methods to prevent driving in the wrong direction: 1. Plan your route in advance before entering the highway; 2. Keep your car navigation or mobile navigation updated and pay close attention to the navigation announcements while driving; 3. If you miss an exit, continue driving to the next exit instead of making a U-turn, reversing, or driving in the wrong direction; 4. Always observe road signs and indicators while driving and avoid driving while fatigued.

What is the correct sequence of operations for starting a car?

The correct sequence for starting a car is: adjust the seat and rearview mirror, fasten the seat belt; first shift to neutral, then turn the key to ignite; press the clutch and shift into first gear; turn on the left turn signal. Safety precautions when starting: develop awareness of observing the surroundings before starting and cultivate good observation habits; keep your eyes looking forward while performing all actions, and never look down under any circumstances. Road conditions are ever-changing, and all actions should be performed based on the feel of your hands rather than by looking down, to prevent unexpected collisions when the car starts moving; ensure proper clutch and throttle coordination to guarantee a smooth start and avoid sudden jerks, stalling, or other human-caused issues. Techniques and methods for starting and shifting gears: start by shifting into gear; after the vehicle stops, always shift into first gear to start again; match the gear with the speed; during the driving test (Subject 3), each gear has a specific speed range; shift gears progressively; during the road test, skipping gears is strictly prohibited. For example, when accelerating to 20 km/h, you can shift from first to second gear but not directly to third. Gear shifting should be swift and decisive; when accelerating and shifting up, coordinate the throttle and clutch properly; keep your eyes on the road while shifting gears; maintaining direction is crucial while driving, so avoid looking down at the gear shift or focusing solely on shifting without paying attention to the direction.
