Can private cars enter the highway late at night?

Private cars are allowed to enter the highway late at night. Only passenger vehicles are prohibited from entering the highway between 2 AM and 5 AM, as the current highway restrictions apply only to large buses or sleeper vehicles. Unless there are special circumstances, such as heavy fog, heavy rain, icy roads, or major traffic accidents, the highway entrance will be closed. It is important to note that driving late at night should avoid fatigue driving, and due to poor visibility at night, extra caution is required. Precautions for driving on the highway at night: Before driving, check the vehicle's condition, including tire appearance and pressure, test the brakes, and always wear seat belts—both front and rear seats. Avoid placing unsecured items in the car. Novice drivers should avoid driving on the highway during snowy, foggy, rainy, or nighttime conditions. Before traveling, familiarize yourself with the entrance and exit points to avoid last-minute searches. When entering service areas or exiting the highway, it's best to glance at the speedometer, as prolonged highway driving can distort speed perception. Avoid letting large vehicles, especially container trucks, follow closely behind you. When overtaking, increase speed—never slow down during the maneuver. Minimize side-by-side driving time. Always move to the fast lane before overtaking, confirm that the other vehicle won't change lanes, then accelerate past. When overtaking large vehicles, do so quickly and use high beams and the horn as a warning.

What are the reasons for the engine warning light in Changan CS35?

The engine warning light may illuminate due to the following 7 main reasons: Sensor malfunction: Sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors may be damaged, have poor contact, or experience signal interruption. When the car's ECU cannot accurately obtain engine data, the engine warning light will illuminate. Fuel quality issues: If fuel or engine oil is not added according to the manufacturer's requirements, it may cause engine wear and trigger the warning light. Poor combustion of the air-fuel mixture: Poor combustion can lead to engine carbon deposits or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as a warning. Issues such as spark plug failure, ignition coil failure, fuel pump failure, or fuel line blockage can cause poor combustion of the air-fuel mixture. Turbocharger issues: Problems with the intake turbo pipeline or turbocharger can also cause the engine warning light to illuminate. The most common issue is turbocharger damage, accompanied by symptoms such as oil leakage, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake issues: If the car's intake system has problems, it may lead to engine pipeline blockage, and in severe cases, the engine warning light will illuminate. A dirty air filter that is not cleaned regularly can cause intake problems. Exhaust issues: Exhaust system failures can also trigger the engine warning light. Common causes include rear oxygen sensor failure, catalytic converter issues, exhaust camshaft and bearing failure, with the catalytic converter being the most frequent culprit. Using leaded gasoline, lead or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions can easily cause catalytic converter issues. Anti-theft system malfunction: If the car's electronic anti-theft system fails or the anti-theft controller does not match the engine electronic controller, the anti-theft system can prevent the engine from operating normally, and the engine warning light will illuminate. If the engine warning light is on, follow these steps: First, check if the engine is running normally. Look for symptoms such as shaking or black smoke. If present, avoid restarting the engine. Note: Do not restart the engine if the red warning light is on. If the engine can be started, turn it off and wait for 5-10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the "ON" position without depressing the clutch. The car will enter self-diagnosis mode after powering on. Wait for 5-10 seconds and observe if the warning light turns off. If the warning light remains on, visit a service center as soon as possible. The service center can use a portable diagnostic tool to read the fault code, identify the issue, and perform targeted repairs.

How often should an electric vehicle be charged?

Electric vehicles generally need to be charged every 150-200 kilometers of driving. During the charging process, the temperature of the electrolyte should be frequently measured. Methods such as reducing the current by half, stopping charging, or cooling should be used to control the temperature between 35-40 degrees Celsius. If the specific gravity of the electrolyte does not meet the required standards after the initial charge, adjustments should be made using distilled water or an electrolyte with a specific gravity of 1.4. After adjustment, charge for another 2 hours until the specific gravity meets the required standards. Currently, the popular pure electric vehicles in China have a range of 150-200 kilometers per charge (theoretical value), while some imported vehicles can achieve a range of over 500 kilometers. Different new energy electric vehicles have varying charging times. Precautions for charging electric vehicles: Avoid overcharging or over-discharging the battery: During the charging process, it is essential to control the charging time reasonably to avoid overcharging. Overcharging can cause the battery to overheat, which may lead to dangers such as spontaneous combustion or explosion. While driving, it is necessary to monitor the battery level. If the battery indicator shows the red zone, the driver should stop driving and charge the vehicle as soon as possible. Driving with insufficient battery power can significantly increase the battery's wear rate. Recommend daily charging: Many people struggle to grasp the appropriate charging frequency for electric vehicles. For short distances, charging every two to three days may suffice. However, it is recommended that drivers charge their vehicles daily. This practice keeps the battery in a shallow cycle state, which is more conducive to extending its lifespan and benefits the driver. Pay attention to the charging plug: If poor contact is observed in the charging plug during the charging process, it should be addressed promptly to avoid overheating. Prolonged overheating of the plug can lead to a short circuit, which may damage both the charger and the battery.

Do I Need to Queue for a Number for the Subject One Exam?

There is no need to queue for a number for the Subject One exam. Neither Subject One nor Subject Four has a fixed order. After receiving the exam materials, candidates should queue up at the exam room on their own, and those who queue first will take the exam first. Seats for the Subject One exam are randomly assigned. Once the exam room is full, candidates must wait for the next batch of exams. Only when a computer becomes available after the previous batch of candidates finishes will the invigilator allow the corresponding number of candidates to enter for the exam. Subject One Exam Process: Bring all documents and enter in advance: Candidates who have successfully scheduled the exam must bring their appointment information and ID card and arrive at the scheduled location before the scheduled time to prepare for the exam. Those without prior appointments are not allowed to enter. Wear a mask to enter the exam room: Before entering the exam room, candidates must wear a mask and present their "health code," cooperate with staff for temperature checks and relevant information registration. Candidates with fever or cough are not allowed to enter and will be treated as absent. Receive the form and queue for the exam: After receiving the exam materials, candidates should queue up at the exam room on their own, and those who queue first will take the exam first. Identity verification: After entering the exam room, candidates usually need to swipe their ID card for identity verification and remove their mask for facial recognition. After verification, the corresponding seat number will be displayed on the computer screen, and candidates can proceed to the designated seat for the exam. Exam answering: From the moment the ID card is swiped upon entry, the exam information will be displayed on the computer at the corresponding seat. Follow the prompts to record a video, and then begin answering questions. If a question is answered incorrectly, it will be immediately indicated, and a red mark will appear on the right side of the answer sheet. If 11 questions are answered incorrectly, candidates can apply for a retake at the identity verification point where they entered. Sign and leave: After the computer-based exam, the score will be displayed on the screen. Click "Confirm" to complete the exam, then sign at the invigilator's desk to validate the score. If the retake is failed, the exam will be terminated, and the candidate can schedule the next exam.
