What is a likely action for drivers when observing a guide sign?

When drivers observe a guide sign, they typically prepare to merge. Guide signs provide crucial information about the roadways, such as directions to destinations, road conditions, and upcoming intersections. These signs often indicate to drivers that they should be ready to adjust their speed, change lanes, or merge into another lane to follow the indicated route or navigate around obstacles.

In the context of driving safely, being prepared to merge when seeing a guide sign helps ensure that drivers maintain proper control of their vehicle and communicate their intentions to other road users. This awareness can prevent sudden or erratic maneuvers that may cause accidents or disrupt traffic flow.
