How Long is the Subject 4 Exam?

[SanJuliette]

Subject 4 exam lasts for 30 minutes. If you make mistakes totaling 12 points (6 questions) during the test, the exam will be terminated. Subject 4: Also known as the Subject 4 theory test or driver theory test, it is part of the motor vehicle driver's license assessment. After the implementation of the Ministry of Public Security's Order No. 123, the Subject 3 test 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." Main Content of Subject 4: Safe and civilized driving operation requirements, knowledge of safe driving under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-traffic accident handling knowledge.

Last time I took the Category 4 driving test, it took me a full 45 minutes. This duration is a standard setting specifically designed for assessing theoretical driving knowledge. The test usually consists of around 50 questions covering topics like safe driving and traffic regulations, averaging about one minute per question. I found this timing just right—not too tight nor too relaxed—the key is maintaining a good answering rhythm. During practice sessions, I made a habit of timing myself and avoiding getting stuck on difficult questions, tackling easier ones first. Staying calm during the exam helps prevent rushed mistakes, as safe driving ultimately concerns lives. The 45-minute limit actually encourages thoughtful consideration. After the test, I reflected that real-world driving requires even more of this time management awareness.

The Subject 4 test has a fixed duration of 45 minutes, typically consisting of around 40 to 50 single-choice and multiple-choice questions. This time frame has been optimized over the years to balance test-taking pressure and fairness. From observing many test-takers, I've noticed that beginners often make mistakes due to poor time allocation. I recommend practicing by dividing the time—spend the first 10 minutes warming up, the next 25 minutes focusing on key questions, and reserve the last 10 minutes for review. Having ample time allows you to check details, such as traffic sign recognition or emergency procedures. The essence of safe driving lies in this kind of focus—the 45 minutes serve as both a test and a lesson in time management. Using apps for practice during preparation can significantly improve your performance.

My experience with the Subject 4 test was that the 45-minute time allocation was thoughtfully designed, giving you ample space to consider each answer. The exam content primarily focused on safety knowledge, such as how to handle accidents and driving in adverse weather conditions. The extended duration prevented test-takers from panicking and reduced misjudgments. As someone who cares deeply about road safety, I believe this reflects the humanized philosophy of driver education: steadiness trumps speed. In real-world driving, every second of decision-making affects others' lives, so the exam reinforces this point. When teaching my child to drive, I emphasized time management—45 minutes is sufficient for you to perform calmly.
