Final answer:
Vertical signs generally give instructions or tell you the law, while horizontal signs may give directions or information.
Step-by-step explanation:
Vertical signs generally give instructions or tell you the law. They are typically used to signal a specific regulation that must be followed, such as a speed limit or a no-entry zone. These signs are placed in a vertical position to ensure that they are easily visible to drivers and pedestrians.
On the other hand, horizontal signs may give directions or information. These signs are usually used to provide guidance, such as indicating the way to a particular location or giving information about nearby attractions or facilities.
