What should drivers watch for when approaching a highway?

When approaching a highway, it is essential for drivers to be alert for vehicles that may be entering the highway or merging into their lane. Highways often have specific entry and merging points where vehicles from interchanges or side roads can join the highway traffic. Being aware of these vehicles is crucial for maintaining safety and preventing collisions.

This awareness includes understanding the speed at which traffic is traveling and recognizing when other vehicles may not be able to merge safely due to limited space. By observing the flow of traffic and anticipating the movements of other vehicles, drivers can make informed decisions on speed, lane changes, and other maneuvers necessary for safe driving on highways.

While it's also important to pay attention to traffic signs, watch for animals on the road, and be aware of workers directing traffic, these factors may not be as immediate or prevalent as the actions of vehicles entering the highway, particularly in more urbanized or congested areas. Therefore, focusing on vehicles coming into the highway or lane is the most critical aspect of safe driving as one approaches these high-speed roadways.
