London, Mar 18 : Lindsay Lohan has enrolled in a substance abuse education class just hours after the warrant issued for her arrest was dismissed.

The `Mean Girls' star attended the Right On Program that offers special DUI classes licensed by the state of California for first, second and multiple offenders.

An hour later, the actress left the center and quickly hopped into her waiting car, reports the Sun.

A US judge dismissed an arrest warrant against the star after ruling Lohan had not violated her probation for a 2007 drunken driving conviction.

The actress' lawyer showed proof that Lohan was in `full compliance' with the SB38 programme she has been following since she was convicted of DUI. (ANI)
