A yellow triangle with an exclamation mark in the car indicates a general vehicle fault. Below is an introduction to common vehicle faults and dashboard warning lights with exclamation marks: Common Vehicle Faults: Common vehicle faults include overheating of the dry dual-clutch transmission, fuel cutoff system intervention or malfunction, parking sensor failure, engine oil pressure sensor failure, traction control system warning, etc. If any of these faults occur, the triangle exclamation mark light on the dashboard will illuminate.

Recently, I encountered that yellow triangle warning light with an exclamation mark in the car, which really startled me. It turns out that it's a general warning light, indicating there might be an issue with the car, such as low tire pressure, a brake system fault, or a broken light. When it lit up while I was driving, I immediately pulled over to check and found a nail had punctured the left front tire, causing a leak. After patching the tire, everything was fine. Ignoring it could lead to serious risks; for example, brake failure could cause an accident. My advice is to find a safe place to stop as soon as you see the light come on, then check the manual or search online for common causes specific to your car model. Paying attention to tire pressure and regular maintenance can prevent many such warnings. Now, I make it a habit to check my tire pressure weekly—it’s hassle-free and gives me peace of mind. If it happens, don’t delay; small issues can turn into big problems if left unattended.

Does Subject 4 Only Have 50 Questions?

Subject 4 consists of a total of 50 questions, primarily presented in the form of case studies, images, and animations. Subject 4, also known as the Subject 4 theory test or driver theory test, is part of the motor vehicle driver's license examination. The main content of the Subject 4 test includes: Safe and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations such as tire blowouts, and knowledge on dealing with traffic accidents. Depending on the type of driver's license being tested, 50 questions are proportionally selected from the corresponding Subject 4 question bank, consisting of 22 true/false questions, 23 single-choice questions, and 5 multiple-choice questions. Making 12 wrong answers (6 questions) during the test will terminate the session. The full score is 100, with a passing score of 90, and the test duration is 45 minutes. Within the three-year period of obtaining a driver's license, you can schedule the Subject 4 test an unlimited number of times. Similar to Subject 1, Subject 4 also offers one immediate retake opportunity. After passing Subject 4, in some places, you can receive your driver's license immediately, or at most within one or two days. Starting from the day you receive your driver's license, the first 12 months are considered the probationary period. During this period, you must display a probationary sign at the rear of your vehicle. The probationary sign is usually issued when you receive your license. If not, you can request one from the vehicle management office. However, if you choose to purchase a probationary sign online, make sure it matches the style issued by the vehicle management office; otherwise, it may be treated as not displaying the required sign.
