On a three-lane road, can the application of a sign be limited to one or two lanes?
Signage: Road markings
Explanation
On a three-lane road, it is possible for a signal to apply only to one or two lanes through **road markings on the pavement**. These markings are essential for directing traffic and ensuring that drivers follow the specific instructions for each lane.
- **Lane traffic lights**: These square traffic lights are designed to be obeyed only by vehicles traveling in the lane where they are placed. This means that the signals can be specific to a single lane, allowing the instructions to vary from one lane to another.
- **Green light in the form of a downward arrow**: Indicates that it is permitted to travel in that specific lane, while a **red light in the form of a cross** prohibits occupying the lane. These lights are examples of how signals can be applied to individual lanes.
Therefore, road markings and lane traffic lights allow signals to be selectively applied to one or more lanes, ensuring an orderly and safe flow of traffic.
