Bolt Banners are items found in the game Cars: Mater-National Championship. They are awarded to the player after they win a race, beat a level of a minigame, or simply complete an event in story mode. There are a total of 350 to be collected in the game.
A Bolt Banner is shaped like a pennant, and is colored red and yellow, with a lightning bolt symbol in the center of it.
Once all 350 Bolt Banners are earned in story mode, a message will appear where the hint would usually be, reading "You beat the entire game! Congratulations!"
