Jose Canseco's model daughter isn't a model citizen ... she just got busted for DUI.
Law enforcement sources tell TMZ ... Josie Canseco was pulled over around 1 AM on the corner of La Cienega and Melrose (right in the heart of Hollywood) after cops observed her hitting a curb.
We're told the 18-year-old -- who's appeared on mom, Jessica's reality show -- was given field sobriety tests, which she didn't pass, and was subsequently arrested. But our sources say cops didn't think Canseco was under the influence of alcohol ... they believe it was drugs.
Canseco was booked around 6:15 AM and, as of this posting, is still locked up on $15,000 bail.
We've reached out to Josie's rep, and also Jose ... no word back yet.
