An unidentified 21-year-old woman is clinging to life at Bellevue Hospital today after getting hit by a tractor trailer truck while riding her bike at 9:40 a.m. in Bushwick. The Post reports that the woman was peddling westbound on Johnson Avenue when she was run over by the trucker as he made a right turn onto Varick Avenue. In cyclist lingo, this is called the "right hook," and it's one of the most common types of accidents. As usual, police did not charge the driver, who's simply described as a 35-year-old man.
