Will points be deducted for incorrect steering wheel posture in Subject 3?

Points will be deducted. The following postures will result in point deductions: 1. Looking down at the gear shift: If the student is unfamiliar with the gear positions and instinctively looks down while shifting gears, even for just 0.1 seconds, the system will detect it and report "incorrect driving posture." 2. Shifting gears too quickly: The computer scoring program for Subject 3 is connected to various sensors in the vehicle. The scoring program is designed to first sense the gear lever moving out of the original gear position, then sense the lever in the neutral position, and finally sense the lever moving into the new gear position. If the lever stays in neutral for too short a time and the neutral sensor fails to detect it before shifting to the new gear, the computer will consider it a wrong gear shift and report an error, resulting in point deduction. 3. Not stepping on the accelerator promptly when starting: When starting, first release the clutch halfway, wait for the car body to begin shaking, then release the handbrake. The moment the handbrake is fully released, immediately step lightly on the accelerator to give gas. If the accelerator is not pressed promptly at this time, it may report "incorrect driving posture."

What are the reasons for the decrease in engine power of the BMW X6?

"The reasons for the decrease in engine power of the BMW X6 include carbon buildup issues, fuel system problems, intake system problems, and engine overheating. Carbon buildup issues, including cylinder carbon buildup, throttle carbon buildup, spark plug carbon buildup, and intake carbon buildup, are directly related to the engine's power output. Fuel system problems, such as using incompatible fuel grades, can lead to a decrease in the car's power output and reduced performance. Alternatively, a blocked fuel tank vent can cause a lean air-fuel mixture, resulting in weak engine acceleration. Intake system problems, such as insufficient air intake, can cause an overly rich air-fuel mixture, leading to a decrease in engine power. For vehicles equipped with turbochargers, a malfunction in the turbocharging system can also result in reduced engine power or performance. Engine overheating, caused by insufficient engine oil, insufficient engine coolant, or malfunctioning engine cooling systems, can increase the engine's load and lead to poor heat dissipation. Solutions for decreased engine power: Promptly clean the engine to remove carbon buildup; replace the air filter or clean the three-way catalytic converter; remove air from the fuel system and drain all fuel from the fuel tank and fuel filter, then refill with the correct fuel grade and quality at a 4:1 ratio, ensuring all air is purged using a hand pump and vent screw; seek professional repair services at a specialized workshop or 4S store, and avoid operating under unclear conditions to prevent further damage to the vehicle. Engine maintenance methods: Use high-quality engine oil; use qualified coolant; regularly clean radiator scale; periodically remove carbon buildup from the car; replace the car's three filters on time; maintain reasonable engine RPM. The car engine is the device that provides power to the vehicle, determining its performance, fuel efficiency, stability, and environmental friendliness. The engine consists of components such as the crankshaft and connecting rod mechanism, valve train, fuel supply system, cooling system, lubrication system, ignition system, and starting system."

Will incorrect steering wheel handling technique result in point deduction in Subject 3?

No points will be deducted, but the correct hand position is more conducive to safe driving. Common incorrect postures: 1. Wrong gear selection: Subject 3 examination explicitly prohibits looking down at the gearshift when changing gears. Many beginners are unfamiliar with gear positions and may engage the wrong gear. During practice, novices should first familiarize themselves with gear positions and learn to shift without looking. 2. Shifting too quickly: If the gear stays in neutral for too short a time before engaging another gear, the neutral sensor may not detect it, causing the system to register a wrong gear selection and deduct points. Beginners should pause in neutral for at least half a second before shifting. 3. Excessive neutral time: While pausing in neutral is necessary during gear changes, staying too long can be problematic. Especially during straight-line driving at high speeds, coasting in neutral can easily exceed 100 meters. Students should pay special attention to keeping neutral time within 100 meters. 4. Delayed throttle application during start: During semi-clutch starts, release the clutch halfway until the vehicle begins to vibrate, then fully release the handbrake. Immediately apply light throttle when the handbrake is fully released. If throttle application is delayed, the system will judge it as "incorrect driving posture." Develop the habit of timely throttle application during practice, even before the vehicle moves.

What is the purpose of green lasers on highways?

Green lasers on highways are "anti-fatigue laser lights." Their function is to illuminate at night, reminding drivers to stay alert and avoid drowsy driving. Highways often have straight roads with few fixed reference points, leading to monotonous driving actions and a single line of sight. Prolonged driving under such conditions can easily cause drowsiness, especially in summer when high temperatures during the day drain physical energy. Freight drivers often undertake long-distance trips at night, making them prone to fatigue driving, which has become a key illegal activity targeted by highway traffic authorities for prevention and enforcement. The installation of laser lights aims to stimulate drivers through changing light patterns, thereby alleviating the visual fatigue caused by the monotonous driving environment. After multiple on-site inspections and collective discussions, highway traffic police have placed these laser lights on relatively straight sections of the road where fatigue driving is more likely to occur. The lasers are adjusted to ensure sufficient brightness while also providing a visual impact. The laser lights operate in two modes: continuous and strobe, with a range of 2 kilometers. Laser lights are just one of many anti-fatigue measures implemented by highway traffic police. Other measures, such as flashing lights and reflective strips on highways, also serve anti-fatigue purposes. However, preventing fatigue ultimately requires raising drivers' awareness and ensuring adequate rest time.

Where can the engine number be found?

The engine number is generally located on the outer surface of the engine cylinder block, on the vehicle's nameplate, or on the nameplate inside the engine compartment. The simplest and most direct method is to check the vehicle's administrative green book or the vehicle registration certificate. The engine number is like a person's ID number, representing each vehicle. It contains very important information about the vehicle. The chassis number is stamped on the vehicle's frame. The specific location varies by manufacturer, so you can refer to your vehicle's manual. The engine model is an identification code assigned by the engine manufacturer according to relevant regulations, industry practices, or the engine's attributes, representing the manufacturer, specifications, performance, features, production process, purpose, and batch of the engine. This includes information such as fuel type, number of cylinders, displacement, and static braking power. Engines installed in cars or multi-purpose passenger vehicles are required to display the professional manufacturer's name, model, and production number. The chassis number, commonly referred to as the Vehicle Identification Number (VIN), is a set of characters assigned by the manufacturer to identify a vehicle. The VIN consists of 17 alphanumeric characters, also known as the 17-digit identification code, chassis number, or 17-digit number. The combination of these characters ensures that no two vehicles of the same model will have the same number within 30 years, making it unique to each vehicle—hence its nickname, "the car's ID card." It is typically found in the following locations: on the vehicle registration certificate and on the lower left side of the front windshield. It's important to note that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer's product line, and multiple engines can share the same model. The engine number, however, is the production number assigned to each individual engine, and no two engines will have the same number. The engine number is composed of several parts: Front section: Includes the product series code, generation symbol, and regional or company code, chosen by the manufacturer as needed but must be approved and recorded by the relevant industry standards organization. Middle section: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Rear section: Includes symbols for structural features and intended use. Tail section: Distinguishing symbol. If differentiation is needed due to improvements or other reasons within the same product series, the manufacturer selects an appropriate symbol. The rear and tail sections may be separated by a hyphen. The chassis number consists of 17 characters divided into three parts. Part 1: WMI—World Manufacturer Identifier (positions 1–3); Part 2: VDS—Vehicle Descriptor Section (positions 4–9); Part 3: VIS—Vehicle Identifier Section (positions 10–17).

Will Running a Red Light When Turning Left Be 100% Captured?

Whether a motor vehicle runs a red light when turning left or going straight, it is considered a traffic violation and will be captured if there are surveillance cameras. According to the relevant provisions of the Road Traffic Safety Law, vehicles must obey traffic signals, including traffic lights, traffic signs, road markings, and the directions of traffic police. If both the left-turn signal and the straight signal are green, going straight from a left-turn lane violates the designated lane rules. When the left-turn signal is red, running the red light will result in penalties. Article 2, Section 1, Clause 2 of the "Scoring Standards for Road Traffic Safety Violations" stipulates that driving a motor vehicle in violation of traffic signal lights will result in a deduction of 6 points per offense. To avoid running a red light, consider the following points: Check the arrow signal first, then the circular signal: Currently, there are two types of traffic signals: arrow traffic lights and circular traffic lights. When arrow signals are present, check the arrow signal first and then the circular signal to avoid running a red light. Note: When encountering a circular red light, right turns are permitted; however, if the right-turn arrow signal is red, right turns are prohibited, and violations will be penalized as running a red light. Brake in time: When the red light turns on, ensure the front of the vehicle does not cross the stop line. If the front wheels accidentally cross, and the rear wheels follow, the electronic camera will capture the violation, resulting in a penalty for running a red light. If the front wheels have just crossed the stop line when the signal turns red, do not proceed through the intersection; wait for the green light. Check the remaining green light time before proceeding: When the green light is flashing, if there is a countdown timer, use it to judge whether to proceed. If there is no timer and the vehicle is close to the intersection with high speed, it may proceed to avoid running a red light due to untimely braking. If the speed is low and the vehicle is far from the intersection, brake immediately to avoid running a red light. Article 38 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" states the following for motor vehicle and non-motor vehicle signal lights: When the green light is on, vehicles are permitted to proceed, but turning vehicles must not obstruct the passage of straight-moving vehicles or pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue. When the red light is on, vehicles are prohibited from proceeding. At intersections without non-motor vehicle or pedestrian crossing signals, non-motor vehicles and pedestrians must follow the motor vehicle signal lights. When the red light is on, right-turning vehicles may proceed if they do not obstruct the passage of other vehicles or pedestrians. Running a red light is not considered a violation under the following circumstances: Yielding to emergency vehicles: Yielding to ambulances, fire trucks, or other emergency vehicles. If a violation is captured by surveillance cameras while yielding, manual review will not record it as running a red light. Even if recorded, you can apply for reconsideration at the traffic police department. Extreme weather: When visibility is so low that even electronic police cannot clearly see the traffic lights, the evidence of violation may be blurry, and no penalty will be imposed for mistakenly running a red light. Emergency situations: When transporting a critically ill patient to the hospital, running multiple red lights may be unavoidable. After delivering the patient, provide proof from the hospital or the rescued individual to the traffic police for verification. If confirmed, the violation records can be cleared. If possible, calling an ambulance is recommended to avoid accidents caused by running red lights. Traffic police direction: During peak hours, traffic police may temporarily direct traffic at major intersections. Drivers must follow the gestures of the traffic police.
