I-81-AccidentThe traffic death of a Washington and Lee student killed on Interstate 81 leads to a father’s drive for a federal requirement for the largest trucks — devices that would limit big speeds. Cullum Owings was killed when a big rig ran into his vehicle the Sunday after Thanksgiving 11 years ago. The trucking industry’s largest association agrees with a call for limiters that would prevent trucks from exceeding 65. WFIR’s Evan Jones has the story.
