It's the end of a hot chick saga -- former Miss Arizona Teen USA Tori Vance will NOT do time for her DUI arrest because she just struck a sweet plea deal ... TMZ has learned.

We broke the story ... 18-year-old Tori was charged with DUI after she made an illegal U-turn in Hollywood back in May, and allegedly showing signs of intoxication.

Tori originally plead "not guilty" to the DUI -- but this week the first time offender made a deal with prosecutors ... pleading "no contest" to reckless driving.

In exchange for her plea,  prosecutors dropped the DUI charges against Tori ... and she got 3 years probation instead of jail time.
