Can I Take the Subject 4 Test with a Temporary ID?

Temporary ID can be used to take the Subject 4 test because it holds the same legal validity as a regular ID. Simply visit any public security bureau, submit your household registration booklet, a recent one-inch black-and-white photo without a hat, and pay a 10 RMB document fee to obtain a temporary ID on the same day. The Subject 4 test consists of 50 questions presented in the form of case studies, images, animations, etc. The total score is 100, with a passing score of 90. Subject 4, also known as the theoretical test or driver's theory test, is part of the motor vehicle driver's license examination. 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 civics knowledge test, commonly referred to as "Subject 4," which assesses "driving ethics." Since this test is conducted after Subject 3, it is commonly called the Subject 4 test, although officially, there is no such designation. If you fail the Subject 4 test, you do not need to retake the previously passed tests (Subject 1, Subject 2, Subject 3). You can schedule a retest on your own without paying additional fees. There are no restrictions on the number of retests, but the driving skill test permit is valid for three years. If the applicant fails to complete all tests within this period, the results of any passed subjects will be invalidated.

What to Do When the Dash Cam Keeps Falling Off the Windshield?

You can use 3M adhesive and bonding promoter to securely attach the dash cam. Here are some tips for installing a dash cam: 1. Before installing the dash cam, ensure the windshield installation area is thoroughly cleaned. 2. For dash cams fixed with adhesive tape, the installation surface must be dry. You can use a hairdryer to heat the adhesive tape for better and more secure adhesion. 3. For suction cup-mounted dash cams, applying a small amount of water to the suction cup before attaching it to the windshield can enhance stability. 4. Prior to installation, determine the optimal position for the dash cam. It's best to install it in the middle or slightly to the right of the rearview mirror for a straight filming angle, which provides more convincing evidence.

How to Stop at a Red Light with an Automatic Transmission

When encountering a red light with an automatic transmission, the following stopping measures can be taken: 1. For short red lights, you can simply press the brake pedal. 2. For long red lights, shift to N gear and engage the handbrake. If the stopping time exceeds 2 minutes, you should shift to N gear to protect the transmission and prevent the transmission fluid from overheating. If the stopping time exceeds 5 minutes, it's best to turn off the engine, shift to P gear, which is both environmentally friendly and fuel-efficient. The starting steps for an automatic transmission are: 1. Insert the key and turn it to the second power position (ignition), wait for the system self-check to complete. 2. Shift the gear lever from P gear to N gear. 3. Release the brake and start the car's engine. 4. Press the brake pedal with your foot, shift the gear lever from N gear to D gear, release the brake and press the accelerator to start. Driving precautions for automatic transmissions include: 1. Start with gentle acceleration, shift to P gear or N gear when starting, and avoid coasting in neutral. 2. Shift back to N gear when waiting at a red light or briefly stopping, and shift to P gear when parking. 3. Do not shift into P gear while driving. 4.

How to Best Control the Clutch in Subject 3?

Clutch operation method: 1. Place your foot parallel to the clutch pedal, ensuring the ball of your foot can press it. When not needed, move your foot to the left. 2. General principle for clutch operation: Press firmly and release steadily (quick press, slow release). Press down decisively in one motion, and release slowly and steadily. Slow release prevents vehicle shaking. 3. Exam regulations prohibit prolonged clutch pressing. Continuous clutch pressing must not exceed 15 seconds. Exceeding 15 seconds is considered coasting in neutral and results in immediate disqualification. 4. Theoretically: Downshift after decelerating, decelerate after braking. Specifically, press the clutch first before braking to ensure the engine doesn't stall.
