Probably the most common mistake made by novice drivers when entering a highway; adapting to the speed of traffic. And in most cases, that means going too slow when the traffic is at full speed. So how fast do we enter? It depends on the speed of traffic. During rush hour, it can almost come to a complete stop, and at normal hours, usually traffic is at full speed. So how do we adapt our speed? Simple, it’s a visual thing. We look at the speed of the vehicles on the highway, but we must not do it at the last moment just before entering. We look from far, then we look again just before merging.
