When driving in fog at night, the lights that should be turned on include fog lights, tail lights, marker lights, and low beams. High beams should not be used. More information about driving in fog at night is as follows: 1. Article 58 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China": When motor vehicles are driving at night without street lights, poor lighting, or in conditions of low visibility such as fog, rain, snow, dust, or hail, they should turn on headlights, marker lights, and rear position lights. However, high beams should not be used when the following vehicle is driving close to the preceding vehicle in the same direction. High beams should not be used because the upward tilt of the high beam axis causes the light to scatter diffusely in the fog, creating a blinding white haze in front of the vehicle, making it impossible to see anything while driving. 2. Before driving in fog, remember to thoroughly check your vehicle's lighting system. While driving, follow the regulations on light usage to maximize visibility and clearly observe the movements of vehicles and pedestrians. When driving in fog, strictly adhere to the speed limits set by traffic rules and avoid speeding. The thicker the fog, the shorter the visibility distance, and the lower the speed should be. When visibility is less than 200 meters but greater than 100 meters, the speed should not exceed 60 km/h. When visibility is less than 100 meters but greater than 50 meters, the speed should not exceed 40 km/h. When visibility is within 30 meters, the speed should be controlled below 20 km/h. If visibility is within 10 meters, it is recommended to stop by the roadside and not continue driving.

What is the method for querying vehicle information through the license plate number?

Through the license plate number query vehicle information method is: 1. Go online and click to enter the online vehicle management office; 2. Click to enter the motor vehicle information query; 3. Input the type of license plate and the license plate number of the motor vehicle to be queried; 4. You can determine whether the vehicle needs to be queried by the body color, vehicle brand, driver, or file number. The license plate number is the plate that identifies the vehicle's identity, and its significance to the vehicle is like the ID number to a person. For example, if the license plate is from Guangzhou City, Guangdong Province, 'Yue' represents Guangdong Province, 'A' represents Guangzhou City, and 'Yue A' is the license plate code for Guangzhou City.

Must the clutch be pressed when braking to decelerate in Subject Three?

Subject Three requires pressing the clutch when braking. The requirements for vehicle speed are relatively high, and it generally involves high-speed driving. The higher the speed, the greater the inertia. If the clutch is pressed first, the vehicle's inertia will be even greater, potentially leading to the dangerous situation of coasting in neutral. Therefore, when decelerating at high speeds, you should first apply the brake to reduce the speed to a certain level, then press the clutch to downshift and further reduce the speed. The road driving skills test for Subject Three generally includes: 1. Contents: Vehicle preparation, simulated lighting test, starting, driving straight, gear shifting operations, changing lanes, pulling over, driving straight through intersections, turning left at intersections, turning right at intersections, passing pedestrian crossings, passing school zones, passing bus stops, meeting oncoming vehicles, overtaking, making U-turns, and nighttime driving. 2. Time: Starting from June 1, 2021, the interval for scheduling the Subject Three test was adjusted from 30 days after passing Subject One to 20 days. For those applying for a medium or large passenger or truck driver's license, the interval for scheduling the Subject Three test was adjusted from 40 days after passing Subject One to 30 days.

Does a Higher Seat Position in Subject 2 Require Earlier Reference Points?

In Subject 2 driving test, a higher seat position requires earlier reference points. When the seat is adjusted higher, each operation should be performed slightly earlier. Conversely, when the seat is lowered, the timing of operations can be slightly delayed. According to the "three-point alignment" principle, these points refer to the driver's eyes, a specific reference point on the vehicle, and the third point where the line connecting these two points projects onto the ground. If the seat height allows better visibility of blind spots beneath the front hood, when aligning the vehicle using a specific reference point, sticking to the original method might actually position the vehicle too far forward, risking crossing the line. Therefore, steering earlier becomes necessary. Conversely, if seated too low, following the original reference point method might leave the vehicle still far from the boundary line, requiring a slight delay in steering operations.

How to Determine Prolonged Occupancy of the Overtaking Lane?

Methods to determine prolonged occupancy of the overtaking lane: using the overtaking lane as a regular driving lane without the purpose of overtaking, thereby hindering other vehicles from overtaking. The overtaking lane on highways is designated for vehicles that are overtaking or meet the required speed standards. However, some drivers occupy this lane for extended periods, forcing other vehicles to overtake from the slower regular driving lanes. Prolonged use of the overtaking lane increases the speed differential with vehicles attempting to overtake, leading to hazardous situations when overtaking from the regular lanes, as it further widens the speed gap with vehicles already traveling there, raising the risk of accidents. The overtaking lane is the leftmost lane on a highway and is only present on highways that meet the standards of a six-lane dual-carriageway.

What does the traffic sign with a question mark and a light bulb mean?

The traffic sign with a question mark and a light bulb is a reminder for drivers not to forget to turn off their headlights after exiting a tunnel. This sign is usually placed at the exit of tunnels on highways. Inside tunnels, the lighting is dim, prompting drivers to turn on their headlights for better visibility. However, many drivers forget to turn them off after exiting the tunnel. This behavior is not only harmful to the vehicle but also poses a safety hazard to other drivers. Hence, such signs are installed to remind drivers to switch off their headlights after leaving the tunnel. When driving on highways, always remember two key points: first, turn off your high beams after exiting the tunnel if you had them on inside, and second, make adjustments to your side and rearview mirrors to minimize the impact of other drivers' high beams on your visibility.

Can Full Synthetic Engine Oil Last for 15,000 Kilometers Before Replacement?

Full synthetic engine oil cannot last for 15,000 kilometers before replacement. The replacement interval for full synthetic oil is 10,000 kilometers or within one year. Methods to determine if engine oil should be replaced: 1. Repeatedly grind the extracted used oil. If impurities are felt, viscosity deteriorates, or it even feels gritty, the oil needs replacement; 2. Hold the extracted oil dipstick at a 45-degree angle under light and observe the oil droplets. If there are excessive wear particles, replacement is required; 3. Take a clean white filter paper or high-quality tissue paper, drip a few drops of oil on it, and wait for the oil to permeate. If the oil shows no powder, feels smooth, appears yellow with clear infiltration, it can still be used. If it appears dark brownish-black with impurities, replacement is necessary.
