1.
noun : When there is a halting or slowing down of cars on a major highway all because they saw the sun shinning in their eyes and are so frightened that they need to slam on their brakes.

This is usually done by morons that don't know their car is equipped with a visor to prevent exactly this occurrence.
Also more common in areas after an overpass, or after a highway wall.
It will ruin your life because you'll realize that you just sat in traffic because a couple of people thought the giant yellow thing was going to kill them and slowed down to a crawl.
"Sorry Im late I was driving on the LIE when I hit some bad Vamire traffic."

"just had to replace my bumper because of some vampire traffic."
