The following are the key points for Subject 4: 1. Obstacles: When you need to change lanes to bypass an obstacle ahead, but an oncoming vehicle is already close to the obstacle, you should reduce speed or stop to give the oncoming vehicle the right of way. 2. Changing lanes: When changing lanes while driving, you should turn on the turn signal at least 3 seconds in advance to alert vehicles behind you. 3. Changing lanes at an intersection: When changing lanes before an intersection, you should follow the guide arrows in the dashed line area to enter the desired lane. 4. Changing lanes to the left: When changing lanes to the left, you should turn on the left turn signal in advance and enter the left lane without affecting the normal driving of other vehicles.
Having taught driving for so many years, I've found that the core of the subject four exam is safe driving. You need to understand the meaning of traffic signals, such as stopping at red lights and proceeding at green lights, as well as various road signs like speed limit indicators. Emergency handling is a crucial part, including how to steady the steering wheel without slamming on the brakes during a tire blowout, or using engine braking to slow down if the brakes fail. Understanding accident liability is also important, such as knowing that in rear-end collisions, the following vehicle is usually at fault. The dangers of alcohol and fatigue driving must be remembered—never drive after even a single drop of alcohol. Other aspects include maintaining a safe distance, especially on highways; using lights correctly when driving at night; and slowing down in rainy or foggy conditions to ensure clear visibility. Lastly, there's civilized driving, like yielding to pedestrians and not parking haphazardly, which not only helps you pass the exam but also prevents accidents and saves lives in real-world driving.
