You can attend the exam as long as the scheduling is successful; receiving an SMS is not mandatory. Below is relevant information about Subject 4: 1. Subject 4: Also known as the Subject 4 theory test or driver's theory test, it is part of the motor vehicle driver's license assessment. After the implementation of "Order No. 139 of the Ministry of Public Security of the People's Republic of China," the Subject 3 test was divided into two parts: besides the road test, a safety and civilization knowledge test was added, commonly referred to as "Subject 4," which evaluates "driving ethics." Since this test is conducted after Subject 3, it is habitually called the Subject 4 exam. 2. The main content includes: safe and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling knowledge.

I've encountered similar issues. As someone with some technical knowledge, the system backend processing appointments might get backlogged, causing SMS delays. SMS gateway transmission involves network signals – weak or busy signals may lead to disconnection; phone security settings like spam filters might divert notifications to junk folders. Also check if the registered phone number was entered correctly; occasional carrier server failures can cause delays. I recommend logging into the 12123 app to confirm appointment status – usually if it shows success, the appointment is valid. If phone signal is poor, try restarting the device or moving to an open area; when contacting the local DMV, provide your ID number for verification. While rare, system bugs can occur, so keep screenshots of your appointment as backup. Generally speaking, be patient – most situations resolve themselves without affecting exam schedules.

How to Deal with Cockroaches in the Car?

Spray cockroach spray into the corners of the car, then close the windows and wait for a day to kill the cockroaches. However, this method is not long-lasting. You can place cockroach bait in areas where cockroaches are likely to appear, such as door gaps, under the seats, and inside the trunk, to lure and kill them. You can directly spray hot soapy water on the cockroaches, but this requires face-to-face contact. Hot soapy water can repel and kill them.

How to Detect Freon Leaks in Cars?

Visually inspect the car's air conditioning pipelines. Freon leaks in the car's air conditioning system usually show signs of oil seepage, which can indicate the presence of a leak. When not performing major disassembly of the air conditioning system, apply soapy water to various parts of the system. Bubbles will appear at the leakage points. Electronic leak detection is a new popular method in recent years. During detection, move the detection probe around areas where leaks are likely to occur.

What to Do If the Car Wheel Hub Gets Scratched?

If it's just a surface scratch, there's no need for repair as it only affects the appearance of the car tire and does not impact the tire's safety performance. If the edge is severely scratched, then it needs to be repaired; otherwise, it might lead to tire air leakage due to improper contact with the tire. If the wheel hub is scratched to the point where the primer is exposed, it also requires repair. The scratched area will wrinkle and continue to expand, and it may also rust and corrode.

How to Self-Rescue When a Car Falls into Water

In any crisis, staying calm is essential for rational self-rescue. Develop an escape plan and keep your face as close to the roof of the car as possible to get more air. If you cannot open the door, then break the window; always keep a safety hammer inside the car and aim for the four corners of the window when breaking it to escape. If you cannot swim, find something buoyant in the car to hold onto before exiting.
