What ratings can Krusty give in The Simpsons: Road Rage?

After finishing a round of Road Rage mode in The Simpsons: Road Rage, Krusty gives the player a performance rating based on how much money they earned during a single round.

I know from experience that the Insane rating is given for earning somewhere between $5,000 and $10,000, but the other ratings are a mystery to me.

What ratings can Krusty give in Road Rage mode? How much money is needed for each?
