Before the move
How we plan a South Carolina load
Every South Carolina move starts with an SCDOT permit for a non divisible load. Our permitting team checks the size, weight and route against SCDOT's rules, then sets the escorts, height pole and travel windows the permit calls for.
South Carolina loads run sunrise to sunset seven days a week, but wide loads stay out of urban rush hours and Myrtle Beach routes on summer weekends.
Superloads need a routing analysis that takes 3 to 5 business days, so we file early.
