What kind of sign typically indicates an approaching expressway?

1. Stop sign

2. Yield sign

3. Expressway sign

4. Speed limit sign

The correct answer is: Expressway sign

An expressway sign is specifically designed to alert drivers that they are approaching an expressway. These signs are typically marked with distinctive symbols or shapes, such as a blue or green background with the word "Expressway" or an emblem that indicates the entrance to a highway system. This type of sign serves to inform motorists of the upcoming transition to higher-speed roadways, where different driving rules and behaviors may apply. Understanding the expressway signs is essential for safe navigation and preparing for the increased speed and traffic flow on such roads. Other signs, like stop signs and yield signs, focus on regulating traffic at intersections and ensuring safety rather than indicating upcoming expressways. A speed limit sign establishes the maximum speed allowed on a given road, and while it can be found on expressways, it does not specifically denote that a driver is approaching an expressway. Therefore, expressway signs best provide the necessary information regarding transitions to expressway driving.
