What action should a driver take before entering a highway?

Before entering a highway, a driver must first accelerate to match the speed of the traffic on the highway. Doing so allows for a smoother and safer merge into the flow of vehicles. This action is crucial because highways have higher speed limits compared to regular roads, and failing to adjust speed appropriately can lead to dangerous situations.

Additionally, checking all mirrors and blind spots is equally important when merging onto a highway. This practice ensures that the driver is aware of other vehicles already on the highway and can merge safely without causing disruptions or collisions. It allows the driver to identify gaps in traffic and to enter the highway at the right moment without endangering themselves or others.

By combining both actions—accelerating to highway speed and carefully checking mirrors and blind spots—a driver enhances their safety during the merge process and increases the overall safety of roadways. This combination of actions ensures that the driver is adequately prepared to join the fast-moving traffic on the highway.
