The 22-year-old actress, best known for her roles in "Jessie" and "The Suite Life on Deck", was apprehended by police after crashing her Audi into a Mercedes in Los Angeles, reported TMZ.
Debby was given a field sobriety test before being arrested for felony driving under the influence (DUI).
The driver of the Mercedes claimed an injury, prompting the felony charge, which a police source explained to the outlet was standard procedure.
However, Debby's charge was dropped to a misdemeanour after only just failing a Breathalyzer test.
