Lindsay Lohan believes she's being denied driving privileges because the paparazzi are constantly on her tail ... so she's asking her lawyer to get a restraining order prohibiting them from chasing her.
As first reported, the L.A. County Probation Department -- along with the DMV -- have given Lindsay the green light to drive again. And Betty Ford was down with it as well.
But sources involved in the decision tell TMZ ... just when Lindsay was supposed the get the keys, Betty Ford decided it was too much of a safety risk to put Lindsay behind the wheel, because the paparazzi were creating an unsafe driving situation.
We're told Lindsay emailed her lawyer this weekend -- with pictures attached showing the paps following her -- asking the attorney to go to court for the restraining order.
Sources say no decision has been reached on whether a restraining order is a viable option. In the meantime, Lindsay is still stuck in park.
