A police report released Tuesday said Kennedy failed several sobriety tests and was swaying and slurring her speech. Kerry Kennedy pleaded not guilty Tuesday to an impaired driving charge stemming from last week's death-defying smashup on a Westchester highway -- and said a seizure was to blame. In a statement she read outside court, Gov. Andrew Cuomo, said doctors believe her recent auto accident on a highway was caused not by illegal drugs or a sleeping pill, but by a seizure stemming from an old brain injury. Kennedy said she would continue to receive treatment for the condition and should be able to live "symptom-free." "I apologize to the other drivers who were on the road that day," she said before thanking her sister Rory and brother Chris for standing by her since the crash. Her statement came hours after police released their report, which said Kennedy, 52, was "slumped over the wheel" of her running Lexus after an erratic tear down Interstate 684. Kennedy -- daughter of Sen. Robert F. Kennedy and niece of President Kennedy -- was arrested Friday on Route 22, where she drove her damaged sedan after smacking into a tractor trailer. "She sped to get off the exit and cut off three more cars in the process," he said. Kennedy's crash came weeks after her best friend and sister-in-law, Mary Kennedy, hanged herself.
– Kerry Kennedy may have appeared to be high on drugs when she was busted last week after crashing her Lexus into a tractor-trailer rig, but she was actually suffering a "partial seizure," she has explained to a judge. Kennedy, daughter of Bobby Kennedy and ex-wife of Gov. Andrew Cuomo, failed a number of field sobriety tests following the Westchester highway wreck, according to local cops. She was found slumped over the steering wheel, was unable to stand on one leg, slurred her words, and had difficulty following instructions to walk and turn, according to a police report. She told officers at the time that she may have mixed up the sedative Ambien with thyroid medication. But yesterday, the 52-year-old mom of three explained outside court that docs told her a "problem" with her brain caused by an undisclosed old injury triggered a "complex partial seizure" and caused her to drive erratically and pass out, reports AP. She made the statement after pleading not guilty to charges that she was driving while impaired by drugs. Results from blood tests are pending. She said after treatment she should be "symptom free." The driver of the truck Kennedy plowed into said he spotted her swerving and drifting into his lane. He honked his horn, but she was "unresponsive" and appeared to be "nodding off," he told the New York Daily News. She revived, slightly, after she slammed into his truck, and tried to flee the scene, he said. "She didn't realize the lug nuts from my tractor tore off her right front tire. She didn't get more than 25 feet before her tire blew," he explained.
