Driving defensively

Driving is not just knowing how to operate the vehicle. There are rules of the road that should be followed. The road is divided into lanes that each lane has a purpose regarding the direction. Some wide roads have 4 or more lanes that driving there should have a sort of decorum to avoid collision. That means you should  not be weaving on the lanes.

Driving defensively is anticipating the reaction or behavior of the other vehicles near you, whether in the opposite direction or not. If you think the vehicle beside you is getting too near for comfort then slow down and let it go ahead. For your own safety, never assume that the driver of the other vehicle knows the rule. Just be aware of the movement and flow so you can avoid those who are getting out of line.
