With this information, the driver is able to successfully scan the intersection and make all needed adjustments to either stop and respond to a potential emergency or pass through this point in space.

When starting to drive, most individuals learn the rules of the road and know to obey traffic lights. When a light turns green, movement into the intersection is started, and, on a rare occasion, the car is broadsided.
