A local politician introduced a bill yesterday that would aim to improve roadway safety and prevent accidents involving big rigs. Senator Bill Monning has made the proposal in response to a fatal crash on Highway 17 over the summer. In July, 25-year-old Daniel McGuire was killed when he was hit by a truck near Lexington Reservoir. The new bill would require additional training for big rig drivers. Currently, commercial truck drivers must pass a written exam. Monning’s legislation would also require trainees to graduate from a commercial driving institution approved by the DMV.
