Tori Vance Arrested -- Miss Arizona Teen USA Busted for DUI

Cops DO arrest hot chicks -- in fact, the hottest teenager in Arizona in 2010 (at least according to the Miss Teen USA competition) was arrested just last weekend in L.A. ... on suspicion of DUI.

Law enforcement sources tell TMZ, 18-year-old ex-Miss Arizona Teen USA Tori Vance was pulled over last Saturday night around 9:15PM after making an illegal U-turn in Hollywood.

The officer approached her Mini Cooper (duh) and law enforcement tells us Tori showed signs of intoxication -- so the cop asked her to get out of the car.

According to law enforcement sources, the officer administered a field sobriety test -- and Tori PASSED WITH FLYING COLORS.

Just kidding, Tori bombed ... so she was arrested. Tori was then taken to a nearby police station and booked for misdemeanor DUI.
