A woman riding her bike the wrong way down a one-way street was injured by a dump truck Wednesday night in the Lower East Side, police said.

The truck was making a right turn onto southbound Ridge St. from eastbound Stanton St. when the accident occurred around 10:15 p.m.

The 50-year-old was traveling against traffic down Ridge, when she was struck by the truck, which ran over both of her legs, cops said.

She was rushed to Bellevue Hospital in serious condition.

The driver remained at the scene but was arrested for driving on a suspended license, police said.
