The actress was alleged involved in a hit-and-run on April 10 and another on August 4, city attorney spokesman Frank Manteljan said.
The 26-year-old Easy A star is set to be arraigned on September 27 and could face up to a year behind bars if convicted of the misdemeanor counts.
Amanda was accused of rear-ending a car on Ventura Boulevard in August with the driver claiming that she only stopped briefly before driving off saying there was no damage and did not provide any insurance details.
The blond starlet told officials that she and the woman had both agreed there was no major damage but LAPD's Lt. Andrew Neiman said that the other driver's Toyota had $800 in damage.
Amanda has also been charged with a DUI following her April arrest where she sideswiped an L.A. County Sheriff cruiser after a night out in Hollywood.
The All That actress later took to her Twitter account to plead with President Obama to "fire the cop who arrested" her and insisting that she doesn't drink. Amanda had refused to take a sobriety test.
Four days later on April 10 she allegedly crashed into a car on a Los Angeles freeway but fled the scene according to the victim.
Amanda was also involved in a minor traffic incident back in May.
