Ravens spokesman Chad Steele said the team waived Hampton on Monday.
North Carolina Highway Patrol Master Trooper John Burgin said Hampton was driving 100 mph in a 55-mph zone on Interstate 77 early Saturday. Hampton also was charged with reckless driving and having an open container of alcohol in his car.
Burgin said Hampton had a blood alcohol level of 0.10 percent, above North Carolina's legal limit of 0.08. Burgin said two passengers were charged with carrying concealed handguns and possessing open alcohol containers.
Steele said the 22-year-old former South Carolina defensive back was signed to a reserve contract in January and had not played for the Ravens.
