How are four lanes divided?

There are no specific national regulations for two or more lanes, but generally urban traffic police departments will set three speed limits: 40, 50, and 60. Some urban ring roads have a speed limit of 80, so it's essential to drive according to the speed limit signs. A moment of inattention could be dangerous.
While driving, I noticed that the lane division on a four-lane highway is quite well thought out. The leftmost lane is generally the fast lane or passing lane, suitable for higher speeds; the middle two lanes are the main travel lanes, where daily driving takes place at moderate speeds, making it easier to maintain a safe distance; the rightmost lane is the slow lane or exit lane, often used by beginners or slower vehicles, and also handy when preparing to exit the highway. These rules help reduce congestion and accidents, such as overtaking only from the left to avoid interference from the right. When driving on the highway, I always remind myself not to stay in the left lane for too long to avoid blocking faster traffic; using turn signals is a must when switching between multiple lanes, and checking blind spots is a top priority for safety. I remember one rainy night when the lanes were slippery, I stuck to the right lane and drove slowly, which helped me avoid the risk of a rear-end collision—these rules can truly save lives! It's also important to note that there may be slight variations in different regions, but the basic principles are universal.
As someone who frequently drives on highways, let me share the rules for using four-lane roads. Simply put, lanes are designated for different speeds and purposes: the leftmost lane is the fast lane, reserved for overtaking or high-speed driving; the next two middle lanes are for regular traffic flow, where 80% of vehicles maintain steady movement; the rightmost lane is the slow lane, intended for trucks or when preparing to exit. The key is maintaining proper spacing—higher speeds in the left lane mean greater risk, so it's best used temporarily. In urban four-lane roads, flexibility sometimes applies: the left lane may allow left turns, while the right lane is for going straight or turning right. When stopping at traffic lights, avoid blocking the way. A common mistake among beginners is crawling slowly in the left lane for extended periods, which is dangerous! Develop the habit of checking mirrors and adjusting position. During peak congestion, choose lanes in advance and avoid sudden braking. Safe driving starts with these details to ensure a smooth journey home.
I always enjoy analyzing road conditions while driving. The four-lane design is for efficiency and safety. Look: the left lane is exclusively for overtaking, so don't drive slowly there and block the way; the middle two lanes are the most balanced, maintaining normal speed here is the steadiest; the right lane is reserved for slower vehicles or those preparing to enter/exit the highway. This is especially important on highways—change lanes promptly when speed mismatches occur to avoid accidents. Remember to regularly check blind spots and use turn signals. These rules aren't rigid; adjust dynamically based on traffic flow, like keeping to the right lanes when traffic is heavy and not occupying the overtaking lane. Develop good habits, and the four-lane system will work smoothly!
