What to Do When Unable to Continue Driving After an Accident on the Highway in Foggy Weather?

When unable to continue driving after an accident on the highway in foggy weather, you must turn on the hazard warning lights and taillights, and set up a warning sign approximately 150 meters behind the vehicle as required. Precautions for driving in foggy weather: Proper use of lights: In foggy weather with low visibility, fog lights and contour lights must be turned on, and high beams should be avoided. Control speed: When visibility is less than 500 meters but greater than 200 meters, the speed should not exceed 80 km/h; when visibility is less than 200 meters but greater than 100 meters, the speed should not exceed 60 km/h; when visibility is less than 100 meters but greater than 50 meters, the speed should not exceed 40 km/h; when visibility is within 30 meters, the speed should be controlled below 20 km/h; when visibility is around 10 meters, the speed should be controlled below 5 km/h. Maintain a sufficient safe distance from the vehicle ahead: Do not follow too closely, and avoid overtaking casually. Additionally, honk the horn frequently to indicate your position. Precautions for driving on the highway: Always pay attention to the signs before service areas. When approaching a service area, merge to the right lane in advance and reduce the vehicle speed to below 100 km/h. Upon entering the service area, strictly adhere to the speed limit signs. The driving lanes within highway service areas are usually marked on the ground. After entering the service area, vehicles should strictly follow these markings to avoid traffic congestion and potential accidents. Service areas also have clearly marked parking spaces. Some drivers, however, park haphazardly for personal convenience, which is highly irresponsible and can easily lead to vehicle congestion.

How many questions are there in Subject 1, and what is the total score?

According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the Subject 1 test for the driving license consists of 100 questions, divided into single-choice and true/false questions, with each question worth 1 point, totaling 100 points. If 11 questions are answered incorrectly during the test, the system will automatically submit the paper and end the exam. Subject 1, also known as the Subject 1 theory test or driver theory test, is part of the motor vehicle driving license assessment. The test content includes theoretical foundations of driving, road safety laws and regulations, local regulations, and related knowledge. The test is conducted on a computer, with a time limit of 45 minutes. Subject 1 test content: Driving license and motor vehicle management regulations; Road traffic conditions and regulations; Road traffic safety violations and penalties; Road traffic accident handling regulations; Basic knowledge of motor vehicles; Local regulations; Knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; Specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject 1 test precautions: During the Subject 1 test, students should pay attention to their attire—no slippers are allowed, and electronic devices and bags are prohibited in the examination room. Bring your ID card and queue to enter the waiting hall. Observe the precautions and procedures on the large screen, and store personal belongings in lockers before entering the examination room. Upon entering, verify your identity at the assigned seat and begin the test. Ensure the camera is aligned with you and adhere to exam discipline. If you fail the first attempt, there is a retake opportunity on the same day. If you fail again, you must pay to reschedule. After the test, queue to collect your score report and sign it—unsigned reports are considered invalid. There is no limit to the number of times you can reschedule the Subject 1 test. Each subject can be taken once, and if you fail, you can retake it once. If you do not attend the retake or fail it, the current test session ends, and the applicant must reschedule. In contrast, Subject 2 and Subject 3 allow only five attempts. Subject 2 and Subject 3 tests must be rescheduled at least ten days later. If you fail the Subject 3 safe and civilized driving knowledge test, the previously passed road driving skills test results remain valid. There are three subjects in the driving test: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the road traffic safety laws, regulations, and related knowledge test; Subject 2 refers to the field driving skills test; Subject 3 is divided into two parts: road driving skills and safe and civilized driving knowledge tests.

Can You Die from Sleeping in a Car with the Windows Closed?

Sleeping in a car with the windows closed can indeed be fatal. Here are the reasons: 1. In a sealed vehicle, the oxygen supply is limited. As a person sleeps, they continuously consume oxygen without fresh air replenishment, leading to hypoxia, suffocation, and potentially death. Additionally, most car interiors are made of PVC (polyvinyl chloride) derived from petroleum, and the adhesives used contain formaldehyde. In an enclosed space, occupants are prone to dizziness. 2. If the air conditioning is running, the car produces significant amounts of carbon monoxide. The concentration of carbon monoxide increases over time, exceeding safe levels within approximately 20 minutes, causing noticeable suffocation symptoms.
