If your vehicle meets the speed requirement for the fast lane, you should drive in the left fast lane. If it does not meet the speed requirement for the fast lane, you should drive in the right slow lane. Here is the relevant introduction: Both lanes are for going straight, but there is a distinction between the fast lane and the slow lane. According to the "Regulations for the Implementation of the Road Traffic Safety Law," "On roads with two or more motor vehicle lanes in the same direction, the left lane is the fast lane, and the right lane is the slow lane. Motor vehicles driving in the fast lane should maintain the speed specified for the fast lane. If they cannot meet this speed, they should drive in the slow lane."

On a straight road with two lanes, I usually choose to drive in the right lane, especially when I don’t plan to overtake. The right lane is generally safer because the left lane is often used for overtaking. If I occupy the left lane, I might block faster vehicles behind me, causing them to brake suddenly or even leading to an accident. Additionally, driving on the right gives me a buffer—if a pedestrian or cyclist suddenly appears from the shoulder, I can move slightly to the left to avoid them. Personally, I make it a habit to plan my route before driving, maintain a steady speed, and minimize lane changes. This not only enhances safety but also saves fuel. Especially during rainy conditions or at night when visibility is low, prioritizing the right lane reduces the risk of accidents. If my car breaks down, it’s also easier to pull over safely. Overall, developing this good habit helps avoid many potential issues and ensures a smooth, pleasant journey to my destination.

As a commuter who frequently drives to work, when there are two straight lanes, I prefer to drive in the right lane to ensure a smoother and more efficient journey. The left lane is generally considered the passing lane, and I use it when no one is overtaking, but if I stay there all day, I might get honked at or trigger road rage from drivers behind me, which affects my mood and fuel efficiency. In practice, during peak hours, I tend to stay in the right lane because it often has more openings when traffic slows down, reducing the need for lane changes and lowering stress. I’ve noticed that choosing a lane also depends on road signs and local customs—for example, rural roads may treat left and right lanes equally, but urban roads require adherence to rules to avoid tickets. Staying in a fixed lane and minimizing lane changes not only improves travel efficiency but also extends tire life. Remember, smart driving comes with experience, making daily commutes more time-efficient and hassle-free.

When driving on a dual-lane road and going straight, I directly choose the right lane because traffic regulations require it: the left lane is reserved for overtaking. If I stay in the left lane without moving, I might get fined and penalized with points, or even cause a rear-end collision. The right lane is safer, and in case of an emergency, I can pull over to handle the situation. In short, it's best for beginners to follow the rules first, develop safe driving habits, and then adapt flexibly to road changes.
