Beginning Mar. 1, tractor-trailers are restricted from using the two right-hand lanes on about 100 miles of interstate highways in South Carolina. The initiative is aimed to increase safety.
The state Transportation Department unveiled signs Friday alerting trucks of the new restriction along portions of Interstate 26 in Berkeley and Charleston counties; I-85 in Greenville and Spartanburg counties; I-77 in York and Richland; as well as I-20 in Lexington and Richland.
Bob Lee, Federal Highway Administration division administrator, said the new restrictions apply to sections of highways that are six or more lanes wide. "Reducing heavy trucks to these two lanes reduces the number of lane changes for trucks," Lee said.
