There is no time limit between Subject 3 and Subject 4, and you can schedule Subject 4 immediately. However, after passing Subject 1, the vehicle office issues a learning-to-drive certificate, which is valid for three years. Below is relevant information about Subject 4: 1. Subject 4 Overview: Subject 4, also known as the theoretical test or driver theory exam, is part of the motor vehicle driver's license assessment. After the implementation of the Ministry of Public Security's Order No. 123, Subject 3 was divided into two parts: the road test and an additional safety and civility knowledge test, commonly referred to as "Subject 4," which assesses "driving ethics." 2. Exam Notes for Subject 4: Upon sitting down, first verify your examinee information. If it does not match your details, check if it is your assigned seat. If it is not, locate your correct seat. If the seat is correct but the information is wrong, report it immediately.

Right after passing Subject Three, I was also very concerned about the timing for Subject Four. Actually, the validity period of the driver's license exam starts from the day you pass Subject One, which is a full three years. After passing Subject Three, you must complete Subject Four within these three years, otherwise all previous results will be voided and you'll have to retake the exams. I remember last year there was a guy at our driving school who waited until two years and ten months had passed before taking Subject Four—he almost wasted all his previous efforts. My advice is to prepare for Subject Four right after passing Subject Three while the momentum is still strong. The questions are simpler than those in Subject One, and you can pass after just a few days of practice. Don’t wait until it’s too late and regret it.

I can totally relate to the time limit for the Subject 4 exam. Nowadays, the system keeps electronic records, and our driving instructor reminded our class last week: it's best to take Subject 4 within three months after passing Subject 3. Although there's technically a three-year buffer period, delaying it means you'll have to readjust to the updated question bank. My cousin went to work in another city after passing Subject 3 and came back half a year later only to find that 20% of the questions were new due to updated traffic regulations, resulting in failing once. There's really no need to push it to the deadline—finishing early means getting your license sooner. A weekend of intensive study is enough.

The driving test indeed has a complete timeline. After passing Subject 1, the Study Driving Certificate you receive is valid for a full three years, covering all subsequent subjects. Simply put, even after passing Subject 3, you must complete Subject 4 within these three years. However, recent pilot policies in some cities now allow combined exams for Subjects 3 and 4, significantly saving time. Implementation varies by local DMV, so it's best to consult your driving school's academic advisor for the latest updates—they're the most informed.

This issue has troubled many trainees. Back when I passed Subject 3, I specifically went to the DMV counter to inquire. The staff member checked the computer records and told me: The key is counting 36 months validity from the date of initial driver's license application. For example, if you passed Subject 1 in January 2024, you must complete all subjects before January 2027. But don't wait until the last six months - the system scheduling might have long queues. At that time, I used the Driving Test Prep app to practice questions for three days, and passing with 90 points was still quite easy.

As someone who just got my license last year, I want to remind everyone to pay attention to this deadline. Subject 4 must be completed within the three-year examination period—don’t be misled by rumors. Our instructor once shared the most nerve-wracking example: a student rushed to take the test on the very last day of the deadline, but the system malfunctioned and delayed the exam by three days, resulting in all their previous scores being reset. To be safe, it’s best not to let more than three months pass between Subject 3 and Subject 4. Plus, getting your license right after passing feels absolutely amazing.
