Amanda Bynes Takes Off As Cop Writes Her A Ticket

Bynes was originally pulled over for talking on a cell phone while driving yesterday afternoon. The officer approached the car and collected all of Amanda's information so he could write up the citation.

But Amanda didn't feel like waiting around ... and hit the gas before the cop could hand over the ticket for the actress to sign.

We're told the cop decided NOT to pursue Bynes because he didn't feel she was dangerous ... and besides, he already had all of her information.

Later that day, Bynes rolled by the police station and signed the ticket ... but we're told she's not off the hook for leaving the scene early.
