How Many Days in Advance Can You Apply for a Driver's License Renewal?

You can apply for a driver's license renewal up to 90 days in advance. According to relevant regulations, drivers must apply for a license renewal within 90 days before the expiration of their current driver's license. Before renewing the license, any traffic violations associated with the driver's license must be resolved. Driving with an expired license is considered driving without a valid license. Regulations for driver's license renewal: If the license has expired for less than one year, you should promptly visit the vehicle management office to renew it. If the license has expired for one to three years, you must apply for a written test (Subject 1) at the vehicle management office and pass the exam to obtain a new license. If the license has expired for more than three years, it will be revoked, and you will need to retake the entire driving test. Required documents include the original ID card, the current driver's license, and three one-inch white-background photos. Locations for driver's license renewal: You can renew your driver's license at the vehicle management office, through the mobile app "Traffic Management 12123," or at police-post convenience service stations. Requirements for applying for a delayed renewal: If a driver is unable to renew the license within the specified time due to reasons such as military service or being abroad, they can apply for a delayed renewal at the vehicle management office where the license was originally issued, within the inspection validity period of the license. The maximum delay period is three years. Note that during the delay period, the driver is not allowed to operate a motor vehicle.

What is the question type ratio for Subject 1?

There is no fixed question type ratio for the driver's license Subject 1 exam; questions appear randomly, with a total of 100 questions, each worth 1 point. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," each question is worth 1 point, totaling 100 points. If 11 questions are answered incorrectly during the exam, the system will automatically submit the test and end the exam. Subject 1, also known as the theoretical exam or driver theory test, is part of the motor vehicle driver's license assessment. The exam content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The exam is computer-based and has a time limit of 45 minutes. Subject 1 exam content: Driver's license and motor vehicle management regulations; road traffic conditions and rules; 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 exam precautions: Candidates should dress appropriately for the exam—no slippers are allowed. Electronic devices and bags are prohibited in the exam room. Bring your ID card and queue to enter the waiting hall. Observe the instructions and procedures on the large screen before entering the exam room, and store personal belongings in a locker. Upon entering the exam room, candidates will be assigned a seat at the identity verification station. Once seated, begin the exam, ensuring the camera is aligned with you and adhering to exam discipline. If you fail the first attempt, a retake is available on the same day. If you fail again, you must pay to reschedule. After the exam, queue to collect your score report and sign it—failure to sign renders the result invalid. There is no limit to the number of times you can reschedule the Subject 1 exam. Each subject can be taken once, with one retake allowed if you fail. If you do not take the retake or fail it, the exam process ends, and you must reschedule. In contrast, Subjects 2 and 3 have only five exam attempts. Subjects 2 and 3 can be rescheduled after ten days. If you fail the Subject 3 safe and civilized driving knowledge test, your passing score for the road driving skills test remains valid. There are three subjects in the driver's license exam: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the road traffic safety laws, regulations, and related knowledge exam. 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. The safe and civilized driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, the official terminology (as per the Ministry of Public Security's Order No. 123) does not include the term "Subject 4."

Why Are All the Dashboard Lights On?

The reasons for all the dashboard lights being on are as follows: 1. CAN bus failure in the ECU, poor contact in the ECU's CAN interface; 2. Excessive dirt and carbon deposits, abnormal air circulation, inability to accurately control normal air intake, resulting in unstable gas content and poor engine performance; 3. Low fuel pressure combined with poor constant pressure performance leads to low system atomization levels, making the car difficult to start. The car dashboard includes door status indicator lights, parking indicator lights, various dashboard indicator lights, battery indicator light, fuel indicator light, washer fluid indicator light, electronic throttle indicator light, front and rear fog light indicator lights, turn signal indicator light, high beam indicator light, seat belt indicator light, OD gear indicator light, recirculation indicator light, VSC indicator light, and TCS indicator light.
