Can the Rearview Mirror Cross the Line During Reverse Parking?

The position of the mirrors is not a criterion for evaluation; as long as the wheels do not cross the line, it is acceptable. The "Motor Vehicle Driving Training Teaching and Examination Syllabus" stipulates that during reverse parking, as long as the vehicle body does not exceed the ground markings, no points will be deducted. The rearview mirrors are protruding, so whether they are considered part of the vehicle body depends on the recognition of rearview mirrors by local examination centers. Points will also be deducted for the vehicle body crossing the line, not entering the parking space, stopping midway, not following the prescribed route, not following the sequence, or exceeding the prescribed time. The full score for both subjects is 100 points, with evaluation criteria set for failure, deduction of 20 points, deduction of 10 points, and deduction of 5 points. The rules for the second subject of the motor vehicle driving license test state that failing to stop midway, rolling back, or not following voice prompts will result in failure. Wheel or body crossing the line will also result in failure. Many students encounter the issue of crossing the line during the second subject learning, and the most common mistake leading to failure is "crossing the line." The main reason for wheel crossing the line is that students have not mastered the correct timing for steering. Besides missing the steering timing, another reason could be the steering speed not keeping up with the vehicle speed. Second Subject Deduction Standards: Not wearing a seatbelt: deduct 100 points. Starting the engine without the gear in neutral: deduct 100 points. Not using turn signals (including starting, changing lanes, overtaking, turning, and parking); turn signals not used for more than three seconds (note this is easily overlooked!); forgetting to turn off turn signals or using them incorrectly: deduct 10 points. Stalling once: deduct 10 points. Reverse Parking: Not following the prescribed route sequence: deduct 100 points. Vehicle body crossing the line: deduct 100 points. Not entering the parking space: deduct 100 points. Before reversing, if the two front wheels do not pass the control line: deduct 100 points. Exceeding the 210-second time limit: deduct 100 points. Stopping midway for more than 2 seconds: deduct 5 points each time. Slope Fixed-point Parking and Starting: After the vehicle stops, if the front bumper is not aligned with the pole line and exceeds 50 cm forward or backward: deduct 100 points. After the vehicle stops, if the front bumper is not aligned with the pole line but does not exceed 50 cm forward or backward: deduct 10 points. After the vehicle stops, if the starting time exceeds 30 seconds: deduct 100 points. Wheels crossing the road edge line while driving: deduct 100 points. Rolling back more than 30 cm when starting: deduct 100 points. After the vehicle stops, if the body is more than 50 cm from the road edge line: deduct 100 points. Not tightening the parking brake after stopping: deduct 10 points each time. After the vehicle stops, if the body is more than 30 cm but less than 50 cm from the road edge line: deduct 10 points each time. Rolling back more than 10 cm but less than 30 cm when starting: deduct 5 points each time. Parallel Parking: After the vehicle stops in the parking space, if the body crosses the line: deduct 100 points. Not using or incorrectly using turn signals when entering the parking space: deduct 10 points. Exceeding the 90-second time limit: deduct 100 points. Body touching the parking space edge line while driving: deduct 10 points each time. Wheels touching the lane edge line while driving: deduct 10 points each time. Stopping midway for more than 2 seconds: deduct 5 points each time. Right-angle Turn: Wheels crossing the road edge line: deduct 100 points. Not using or incorrectly using turn signals during the turn, or not turning off turn signals after the turn: deduct 10 points. Stopping midway for more than 2 seconds: deduct 5 points each time. Curve Driving: Wheels crossing the road edge line: deduct 100 points. Stopping midway for more than 2 seconds: deduct 100 points. Not driving in second gear or above: deduct 5 points.

Why are there few buyers for the BMW i3?

BMW i3 has few buyers because: Electric vehicle: The visibility rate of the BMW i3 on domestic roads is extremely low, making it a rare model. This is mainly because the i3 is a new energy vehicle, which inherently has a limited target audience. Performance: Taking the 2020 Quick Charge Comfort model as an example, its NEDC range is only 340km. Any electric vehicle produced by Chinese traditional automakers in 2019 outperforms the i3 in terms of range. For instance, the GAC New Energy Aion S has a range of 410km even in its entry-level model. In terms of power performance, the 2020 i3's motor output is only 170kW/250Nm, with a 0-100km/h acceleration time of about 7.3 seconds, still offering no advantage.

What does engine compression ratio mean?

Engine compression ratio refers to the degree to which the engine's gas mixture is compressed, expressed as the ratio of the total cylinder volume before compression to the cylinder volume after compression. The following is a detailed introduction to engine compression ratio: Utilization of engine compression ratio: To meet the requirements of the National IV (Euro IV) emission standards for carbon emissions (i.e., fuel consumption), automobile manufacturers generally increase the engine compression ratio to between 9 and 12. Among these, 9 to 10.5 is mainly used for turbocharged engines, while 10.0 to 12 is primarily used for naturally aspirated engines. Definition of engine compression ratio: The ratio of the total cylinder volume to the combustion chamber volume in an internal combustion engine is an important structural parameter. When the piston is at the bottom dead center, the cylinder has the maximum volume, denoted as Va; when the piston is at the top dead center, the volume inside the cylinder is called the combustion chamber volume, denoted as Vc.

What Are the Symptoms of a Faulty Oxygen Sensor?

Oxygen sensor failure manifests in the following ways: Increased Fuel Consumption: Carbon buildup on the oxygen sensor can cause abnormal signal output, leading to an imbalance in the engine's air-fuel mixture ratio, which increases fuel consumption. Increased Pollutant Emissions: The vehicle may fail the annual inspection due to excessive tailpipe emissions. Although the three-way catalytic converter can purify exhaust gases, its capacity is limited. If the oxygen sensor malfunctions, incomplete combustion in the engine can result in higher pollutant emissions. Black Smoke Emission: Abnormal operation of the oxygen sensor disrupts the air-fuel ratio, causing black smoke to be emitted.

Where to buy windshield washer fluid?

Automotive windshield washer fluid can be purchased at supermarkets, gas stations, 4S stores, car beauty shops, or auto parts markets. Below are the methods for refilling windshield washer fluid and its functions: Methods for refilling windshield washer fluid: Use the wiper operation knob to first spray out the old windshield washer fluid. After completely spraying out the existing fluid, open the windshield washer fluid filler port and add a small amount of the new windshield washer solution. Then, turn on the windshield washer switch again to clean out any remaining old fluid. When the spray nozzle no longer emits fluid during the second spray, add more windshield washer fluid. After filling, securely close the cap. Functions of windshield washer fluid: Maintains the transparency of the windshield during nighttime driving; extends the lifespan of the glass and wipers; prevents window icing in winter; prevents static electricity on the windows.
