How many points are deducted for failing to undergo annual inspection as required?

Failing to undergo annual inspection as required will result in a deduction of 3 points. Annual inspection time requirements: Small and micro non-operational passenger vehicles are exempt from inspection for the first 6 years. For vehicles over 6 years but less than 10 years old, inspection is required every two years. For vehicles over 15 years old, inspection is required every 6 months. Operational passenger vehicles must be inspected annually within the first 5 years, and every 6 months thereafter. Trucks and large/medium non-operational passenger vehicles must be inspected annually within the first 10 years, and every 6 months thereafter. Imported vehicles follow the same rules as other vehicle types and can undergo regular inspection at any testing facility. Annual inspection precautions: Vehicles that fail the annual inspection must be repaired within a specified time limit. If they still fail after the deadline, the vehicle management office will confiscate their license plates and prohibit further operation. Vehicles that do not undergo annual inspection without reason or fail the inspection are prohibited from driving on roads and cannot be transferred. Vehicles that meet scrapping conditions or exceed the prescribed service life will not be inspected, and their license plates will be revoked with the files canceled, leading to scrapping.

What are the functions of a sewer cleaning and suction truck?

Sewer cleaning and suction trucks integrate the functions of flushing, dredging, suction, and reverse discharge. Functions of the suction truck: It is a new type of sanitation vehicle designed for collecting, transferring, and transporting sludge and sewage to avoid secondary pollution. The suction truck can perform self-suction and self-discharge, operates quickly, has a large capacity, and is convenient for transportation. It is suitable for collecting and transporting liquid substances such as feces, slurry, and crude oil. Working principle of the suction truck: Since the suction hose is always submerged below the liquid surface, when the air inside the tank is sucked out and cannot be replenished, it becomes increasingly thinner, resulting in a pressure inside the tank that is lower than atmospheric pressure. Under the effect of atmospheric pressure, the fecal liquid enters the tank through the suction hose. Alternatively, when the siphon pipe is close to the bottom of the tank and air is continuously pumped into the tank without an outlet, it becomes compressed, causing the pressure inside the tank to be higher than atmospheric pressure. Under the effect of compressed air, the fecal liquid is discharged out of the tank through the siphon pipe and suction hose.

Why Can't a New Energy Vehicle Shift Gears?

The reasons why a new energy vehicle cannot shift gears are as follows: Positioning Ball Head Loses Function: The positioning component of the gear lever's positioning ball head loses function, allowing the gear lever to rotate freely around its own axis, making it impossible to accurately control the gear position. This may be due to the wear of the spherical working surface at the lower end of the gear lever, preventing it from controlling the shift fork or the shift head's groove, making both gear engagement and disengagement impossible. For the former, the fault can be eliminated through repair; for the latter, the gear lever must be replaced. Clutch Cannot Disengage: The clutch cannot fully disengage, while the transmission's shifting mechanism operates normally. This fault can be resolved by adjusting the clutch or replacing certain clutch components to ensure the clutch has appropriate free play and disengagement clearance. Shift Fork Loosens: The shift fork is loose, severely bent, deformed, or worn. In this case, the gear lever's movement reaches the position, but the shift fork's movement does not, causing severe impact and inability to engage the gear. This situation requires opening the transmission cover for inspection and repair, and replacing the shift fork if necessary.

What Does a Driving Physical Examination Include?

The physical examination includes height, vision, color discrimination, hearing, upper limbs, and lower limbs. The specific details of the driving physical examination are as follows: Height Examination: 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. This is the first step in the driving physical examination. Vision Examination: 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, uncorrected or corrected visual acuity must be at least 4.9. Color Discrimination Examination: Applicants must not have red-green color blindness. This requirement aligns with the vision examination in the driving physical. Hearing Examination: Applicants must be able to distinguish the direction of sound from a tuning fork placed 50 cm away from each ear. Upper and Lower Limbs Examination: Applicants must have both thumbs intact, with at least three fingers functional on each hand, and normal limb and finger movement. Lower limb movement must also be normal. For manual transmission vehicles, the difference in leg length must not exceed 5 cm. For automatic transmission vehicles, the right lower limb must be fully functional.

How many points can be deducted from a probationary driver's license?

During the probationary period, a maximum of 11 points can be deducted from a driver's license. The relevant legal knowledge and maximum point deductions for driver's license penalties are as follows: Relevant Legal Knowledge: For drivers holding licenses for large buses, tow trucks, city buses, medium-sized buses, or large trucks, if they accumulate 6 or more points (but less than 12) during the one-year probationary period, their probationary period will be extended by one year. If they again accumulate 6 or more points (but less than 12) during the extended probationary period, their probationary driving qualification for the corresponding vehicle type will be revoked. Maximum Points Deductible During Probationary Period: For a C1 driver's license, a maximum of 11 points can be deducted during the probationary period. For C-class licenses and motorcycle licenses, as long as the total points deducted do not reach 12, there will be no consequences, and the probationary period will not be extended. However, if 12 points are accumulated, the license will be directly revoked. To drive again, the individual must reapply and start the licensing process from scratch. Therefore, it is crucial not to accumulate 12 points during the probationary period for C-class licenses, meaning a maximum of only 11 points can be deducted.

Are There Any Missed Captures for Running a Red Light?

There are instances where running a red light may not be captured, due to the following reasons: not all intersections have surveillance cameras; while probes have monitoring capabilities, traffic police typically do not collect signal light monitoring data unless an accident occurs. Running a red light refers to the act of a motor vehicle violating traffic signal instructions by crossing the stop line and continuing to move when the red light is on, prohibiting passage. The determination of running a red light requires three photos: the vehicle crossing the stop line, the vehicle moving to the middle of the intersection, and the vehicle reaching the opposite side of the intersection. Capturing these three photos confirms the violation. If there are cameras, they will capture the violation. Whether it's a left turn or going straight through a red light, both are illegal acts. According to Article 90 of the Road Traffic Safety Law: vehicles not following traffic signals will be penalized with 6 points, regardless of whether they are going straight, making a left turn, or even when there is a U-turn signal. Safe driving in compliance with traffic rules is mandatory. Definition of Left Turn Running a Red Light: Running a red light is determined by the vehicle's stop line; crossing the line when the red light is on is illegal. The capture mainly records the vehicle's movement during the red light, focusing on significant positional changes. If the front wheels just cross the stop line when the red light turns on and the vehicle stops immediately, traffic authorities will not penalize it. However, if the vehicle continues to move completely after crossing the line, it is considered a violation and will be penalized. That is, the vehicle completes the act of running a red light by crossing (pressing) the line, continuing to move during the red light, completely crossing the line, and entering the intersection during the red light. Here are some ways to avoid running a red light: First look at the arrow light, then the circular light: Currently, there are two types of indicator lights: arrow traffic lights and circular indicator traffic lights. When an arrow light is present, first observe the arrow light and then the circular light to avoid running a red light. Note: When encountering a circular red light, right turns are allowed; when encountering an arrow signal light where the right-turn arrow is red, right turns are prohibited, otherwise it 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 it, resulting in a penalty for running a red light. If the front wheels have just crossed the stop line when the signal turns red, passage through the intersection is prohibited; wait for the green light before proceeding. Check the green light countdown before proceeding: When the green light is flashing, if there is a countdown, use it to judge; if there is no countdown, 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 slow and the vehicle is far from the intersection, brake immediately to stop and avoid running a red light. Article 38 of the Implementation Regulations 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 pass, 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 to pass. When the red light is on, vehicles are prohibited from passing. At intersections without non-motor vehicle or pedestrian crossing signals, non-motor vehicles and pedestrians should follow the motor vehicle signal instructions. When the red light is on, right-turning vehicles may pass if they do not obstruct the passage of other vehicles or pedestrians. Running a red light is not considered illegal under the following circumstances: Yielding to special vehicles: Yielding to ambulances, fire trucks, and other special vehicles. If captured by surveillance cameras while yielding, manual review will not record the act of running a red light. Even if recorded, one 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. Blurred evidence photos may result in accidental running of a red light, for which traffic police will not penalize. Emergency situations: Transporting a critically ill patient to the hospital may involve running multiple red lights, for which the standard 12-point penalty would be insufficient. After delivering the patient, the citizen can provide hospital or patient documentation to the traffic police for verification. If confirmed, the violation records can be expunged. If possible, calling an ambulance is advisable to avoid accidents caused by running red lights.
