What does straight through at an interchange mean?

Straight through at an interchange generally means that you can proceed straight or make a left turn at the upcoming intersection. Below is a partial introduction to interchanges: Introduction: An interchange is a three-dimensional crossing where roads intersect at different levels. It directs conflicting traffic flows onto roads at different elevations, ensuring both smooth traffic flow and safety. Components: An interchange mainly consists of three parts: the overpass (or underpass), the approach, and the ramp. The overpass is a bridge that crosses over or tunnels under another road. The approach is the section of road that connects to the overpass. The ramp is the section that connects the road to the lower level of the overpass. Cloverleaf interchanges also include ramps that connect the upper and lower intersecting roads.
When I first started driving, I was a bit confused about the meaning of going straight at an interchange. Simply put, it means the roads are designed as grade-separated intersections, like overpasses on highways, where two roads cross at different levels. You can drive straight ahead without turning. The first time I encountered such a place, I was flustered, thinking I had to change direction. Later, I realized that as long as I followed the straight-ahead signs and arrows, I could pass through smoothly. The grade-separated design is intended to reduce traffic jams and accidents because turning and straight-going vehicles are separated into different levels, significantly improving safety. Now, I often drive on such roads, and once I got used to it, I found it really convenient—just maintain speed and lane position, and don’t get nervous or mistake the exit. When encountering forks in the road, pay extra attention and check the signs early to avoid missing your turn. This structure is widely used in urban expressways, and new drivers just need to practice a few times to get the hang of it.
Every day on my commute, I pass through several interchanges. Going straight means driving directly forward without turning or changing lanes at the intersection. This design is quite clever—roads are divided into upper and lower levels, allowing for rapid vehicle diversion. I've encountered many places where driving straight during the morning rush hour lets me pass through smoothly, unlike at-grade intersections where you have to wait at traffic lights and get stuck for ages. Operationally, it's very simple: spot the signs in advance, align with the straight lane, and stay focused. If you choose the wrong direction, you'll miss the exit. I think this has solved a major issue in urban traffic, especially on main roads, making the flow of vehicles much smoother. Safety first—maintain proper distance and speed when crossing to reduce the risk of rear-end collisions. Practice a few times, and you'll get the hang of it.
