Why Wasn't I Penalized for Making a U-Turn Over Double Yellow Lines?

Possible reasons for not receiving a penalty include: the system not updating the vehicle owner's violation records, absence of surveillance cameras capturing traffic violations on the current road segment, malfunctioning surveillance cameras, or making a U-turn over dashed double yellow lines. According to Article 90 of the "Road Traffic Safety Law of the People's Republic of China": Motor vehicles violating prohibitory signs or markings shall be given a warning or fined between 20 and 200 yuan, with 3 demerit points recorded. Motor vehicle violations of prohibitory signs or markings include the following behaviors: Crossing or driving over solid single or double yellow lines during travel. Temporary or prolonged parking in no-parking zones. Making U-turns in no-U-turn zones or left turns at no-left-turn intersections are considered violations of prohibitory markings. Prohibitory markings refer to solid yellow lines on the road and no-parking signs; driving over them constitutes a violation. Failing to drive in the corresponding lane as indicated by road markings at intersections. Additional behaviors by motor vehicles that may incur penalties include: Drunk driving: For driving under the influence of alcohol, offenders will be detained for 15 days, have their driver's license suspended for 6 months, and fined 1,000 yuan. For driving commercial vehicles under the influence, offenders will be detained for 15 days, have their license suspended for 6 months, and fined 2,000 yuan. Driving after drinking: For driving after consuming alcohol, offenders will have their license suspended for 3 months and fined 300 yuan. For driving commercial vehicles after drinking, offenders will have their license suspended for 3 months and fined 500 yuan. Overloading or overcapacity: For passenger vehicles exceeding capacity by less than 20% or freight vehicles exceeding load by less than 30%, a fine of 500 yuan will be imposed. For exceeding capacity by 20% or load by 30%, a fine of 2,000 yuan will be imposed. Speeding: For exceeding the speed limit by 50%, offenders will be fined 1,000 yuan and have their license revoked. Driving modified or scrapped vehicles: Modified or scrapped vehicles on the road will be confiscated and forcibly scrapped. Drivers of such vehicles will be fined 1,500 yuan and have their license revoked. Driving with 12 demerit points: Drivers continuing to drive after accumulating 12 demerit points will be fined 800 yuan. Unlicensed vehicles parking illegally incur double penalties: 6 demerit points and a 200 yuan fine. For drivers removing license plates to evade penalties, traffic police will issue fines by recording and photographing the chassis number, applying double penalties.

What is the boundary when meeting on a curve?

When driving a taxi and meeting on a curve, the centerline of the road should serve as the boundary. If there is no centerline, maintain a certain lateral distance; drive on the right side of the lane; and keep a lower speed. Below is an introduction to the division of responsibility in curve traffic accidents: According to Article 45 of the "Traffic Accident Handling Procedures": After investigation, the traffic management department of the public security organ shall determine the responsibility of the parties based on the role of their actions in causing the traffic accident and the severity of their fault: 1. If the traffic accident is caused by the fault of one party, that party shall bear full responsibility; 2. If a party flees, causing changes to the scene or loss of evidence, making it impossible for the traffic management department to verify the facts of the accident, the fleeing party shall bear full responsibility; 3. If a party intentionally damages, forges the scene, or destroys evidence, they shall bear full responsibility.

What type of engine oil should be used for the 10th-generation Civic?

The 10th-generation Civic should use SM or higher-grade fuel-efficient engine oil, or other commercially available engine oils with SAE viscosity specified by Dongfeng Honda that are suitable for the ambient temperature. Below are the specific details of the 10th-generation Civic: 1. Configuration: The interior adopts an ST-Line style, featuring a 12.8-inch central control screen paired with a 10.1-inch LCD instrument panel. It is equipped with full-speed adaptive cruise control and active safety systems, among other features. 2. Powertrain: It is powered by a 2.0T turbocharged engine with a maximum power output of 180 kW and a peak torque of 390 Nm, mated to an 8-speed automatic or 8-speed manual/automatic transmission. There is also a variant with a 2.7T V6 turbocharged engine, delivering a maximum power of 237 kW and a peak torque of 500 Nm, paired with an 8-speed automatic transmission.

What is the reason for the speedometer not working?

Most of the time, it is due to a damaged speed sensor, which requires repair. Below are some related extended information: 1. Speedometer: It actually consists of two gauges. One is the speedometer, and the other is the odometer. Traditional speedometers are mechanical. A typical mechanical odometer is connected to a flexible shaft, inside which there is a steel cable. The other end of the flexible shaft is connected to a gear in the transmission. The rotation of the gear drives the steel cable to rotate, which in turn rotates a magnet inside the speedometer's housing. 2. Odometer: The odometer is a digital instrument. It engages with the worm gear on the speedometer's drive shaft through the transmission gears of the counter drum, causing the counter drum to rotate. Its characteristic is that when the upper drum completes one full rotation, the lower drum rotates 1/10 of a turn. Like the speedometer, modern odometers also include electronic versions, which obtain mileage signals from speed sensors. The accumulated mileage data in electronic odometers is stored in non-volatile memory, allowing the data to be preserved even when there is no power.

What happens if a car's radiator runs out of water?

The car cannot continue to drive if the radiator runs out of water, and severe cases may lead to engine failure. The functions of a car's radiator are: 1. The cooling system of the radiator dissipates excess and unnecessary heat from the engine, ensuring the engine operates at normal temperatures under various speeds or driving conditions; 2. The radiator is a heat exchanger for water-cooled engines, maintaining the engine's normal operating temperature through air convection cooling; 3. Once the engine coolant in the radiator boils and vaporizes due to high temperature, causing the pressure to exceed the set value, the radiator cap releases the pressure by overflowing, reducing the coolant and preventing the cooling system pipes from bursting.

How many points are deducted for not turning off the engine when getting off the car in Subject 3?

In some regions, it is not necessary to turn off the engine, and no points will be deducted. However, in other regions, turning off the engine is required, and failing to do so will result in a deduction of 100 points. It is best to clarify this before the exam. Below is an introduction to the relevant content: 1. Subject 1: Road traffic safety laws, regulations, and related knowledge test. It is a written test conducted on a computer, with a full score of 100. A score of 90 or above (including 90) is considered passing. 2. Subject 2: Field driving skills test. It involves actual driving in a designated area and is only categorized as pass or fail. The test includes five mandatory tasks performed in sequence: reversing into a parking space, parallel parking, S-curve driving, right-angle turning, and starting and stopping on a slope. The full score is 100, and a score of 80 or above (including 80) is considered passing. 3. Subject 3: Road driving skills test. It involves actual driving on a road or simulated area, with a full score of 100. For large buses, a score of 90 or above is passing; for large trucks, 80 or above; and for other vehicle types, 70 or above. 4. Subject 4: Safe and civilized driving-related knowledge. It is a written test with a full score of 100, and a score of 90 or above (including 90) is considered passing.
