The World Wide Tours bus crash took place at about 5:30 a.m. on March 12, 2011, in the southbound lanes of the New England Thruway segment of Interstate 95 within Pelham Bay Park near Split Rock at the border between the Bronx and Pelham Manor, New York. The bus was returning to Chinatown, Manhattan, from the Mohegan Sun casino in Uncasville, Connecticut. It swerved and collided with a metal sign pole, which ripped through it and tore off most of its roof. Thirteen passengers died at the scene, two died at hospitals, and all seventeen others on board were injured.

The truck driver was located by authorities, denied the bus driver's account and was cleared of responsibility. State officials revoked the bus driver's driving privileges after reports became public of Williams's criminal record, which includes having served time for convictions of manslaughter and larceny.

Prosecutors argued that Williams was too tired to get behind the wheel, and was so sleep-deprived that his actions were no different than someone driving under the influence. Williams was held in custody from September 2011 until the end of his trial due to being unable to
