Signage: Vertical signs
The symbols on illuminated regulatory signs are white because this color is easily discernible for drivers, ensuring clarity and safety in road signage.
Explanation
**Illuminated regulatory signals** use **white symbols**. This can be observed in lane traffic lights, where white lights indicate specific actions for drivers. For example, a **white light in the shape of a downward arrow** signals drivers to change lanes because the current lane is going to close.
