Lane Use Control Signs vs Lane Control Signals (Simple Guide)
When driving on busy roads, you often see arrows above lanes or on white rectangular signs at intersections.
Some signs tell you:
- You must turn left
- You must go straight
- You can turn or go straight
Many people get confused between:
- Lane Use Control Signs
- Lane Control Signals
They sound similar, but they are not the same.
Let’s explain it in very simple words.
🔵 What Are Lane Use Control Signs?
Lane Use Control Signs are traffic signs that tell drivers which direction they can or must go from a specific lane.
👉 These signs are usually rectangular or square with black arrows or text on a white background.
They control lane movement by using arrows to guide traffic.
These signs either:
- Allow certain movements — Drivers are permitted to go in the directions shown.
- Require a specific movement — Drivers must follow the direction shown and cannot choose another option.
👉 If a direction is shown, you can go that way or must go that way depending on the sign.
👉 If a direction is not shown, you are not allowed to travel in that direction.
In simple words, these signs control how vehicles use a lane by clearly showing permitted or mandatory movements.
