What is a crucial action to take when entering a highway?

When entering a highway, looking for signs about the speed limit is crucial because it helps ensure that you integrate safely with other traffic. Highways typically have higher speed limits than urban or rural roads, and understanding the current speed limit is important for maintaining safe driving practices. This awareness allows you to adjust your speed accordingly and merge into traffic without causing disruptions or unsafe situations.

Following the speed limit signs promotes not only your safety but also that of other drivers on the highway, creating a smoother flow of traffic and reducing the risk of accidents. It's essential to be aware of your surroundings and any regulations indicated by these signs as you prepare to merge onto the highway.
