Legal size & loaded measurements
General width
8′6″Ordinary vehicle-and-load limit; safety-device, vehicle and load exceptions may apply.
Loaded height
13′6″Ordinary vehicle-and-load limit; listed exceptions and actual route clearances apply.
Loaded dimensions
South Carolina baselines are 8 feet 6 inches width and 13 feet 6 inches height; length, overhang and permitted width/height are configuration- and route-specific.
Axles, weight & bridges
Use wheel/axle weights, groups, spacing, tire type, gross weight, configuration, road class and bridge formula; GVW alone is not a South Carolina decision.
Loaded width
South Carolina's statutory outside-width baseline is 102 inches, exclusive of approved safety devices; exceptions and permitted dimensions are separate paths.
Loaded height
South Carolina's general height baseline is 13 feet 6 inches; a narrow automobile-transporter/saddle-mount exception has its own permit and liability conditions.
Permits, routes & larger loads
Roads & authorities
SCDOT selects and conditions state routes; confirm local, toll, federal, private and facility route-owner permissions separately.
When a permit is needed
A nondivisible load or vehicle outside statutory size/weight requires the applicable SCDOT permit path; single-trip permits are route-specific and valid for seven days for one move unless the issued permit says otherwise.
Larger-load review
Qualifying multiple-trip products have published default bands, while loads over 130,000 pounds, single axles over 20,000 pounds, 16-foot height or wider/superload dimensions need additional route/engineering review.
State permit fees
Single-trip agency fee example
$30 for this South Carolina planning example: a nondivisible load measuring 8′7″ wide, 13′ high and 70′ overall, at 72,000 lb gross on a five-axle rig with a 48′ trailer. The example uses 100 in-state miles. Change the load details in the calculator for your move.
What the agency estimate includes
The calculator applies South Carolina's maintained single-trip permit schedule to the loaded vehicle and the supplied fee inputs. It itemizes the supported state charges, including weight or distance charges where applicable. Annual permits, special products, local permissions and payment-method charges need their own applicable schedule.

About the example equipment
The samples use ODPermit’s editable 48 ft flatbed · 5 axles planning profile. Loaded dimensions, gross weight, 100 state miles and Texas registration are example inputs, not a capacity rating or a route approval. Replace them with your actual setup.
Great Dane Freedom trailer specifications — 48 ft platform; the illustrated 40 in drop deck and 20 in drop support a 60 in upper-deck planning height. Combined tare and tractor geometry are editable ODPermit assumptions.
Pilot cars, height poles & surveys
14′6″-wide load example
Example: 14′6″ wide × 13′ high, 75′ overall, 72,000 lb gross, zero overhang or rear projection, ordinary nondivisible freight in daylight. All road types: 1 front and 1 rear pilot cars.
17′6″-high load example
Example: 9′ wide × 17′6″ high, 75′ overall, 72,000 lb gross, zero overhang or rear projection, ordinary nondivisible freight in daylight. At 16 ft high or above, provide a route survey certified by the applicant before permit issuance. All road types: 1 front (height pole required) pilot car.
Travel hours & road restrictions
Travel hours
Travel is generally sunrise-to-sunset, with width-dependent urban/school-day windows and product-specific continuous-movement requests; the issued permit and current bulletin control.
Current route restrictions
Check holidays, Myrtle Beach summer routes, urban windows, weather/visibility, lane and bridge restrictions, convoy spacing and posted climatic restrictions before departure.
Signs, flags & safety equipment
Safety equipment
Use 12-inch-by-7-foot OVERSIZE/WIDE LOAD signs, 18-inch flags, required amber lights, escort radios/headlights, securement, registration, insurance and weather controls exactly as the current permit requires.
What the driver needs
Carry the permit
Sign the permit on receipt, carry it in the towing vehicle, carry the required route map and present the packet for inspection.
Prepare the driver packet
The driver packet must match the signed permit, towing vehicle/trailer identifiers, route map, dates, dimensions, escorts and any survey, insurance or engineering attachments.
Special equipment & permit programs
Special permit programs
Containerized cargo, mobile homes, bulk agriculture, cotton, sheet tobacco, culvert pipe, house moves, cranes and superloads each have scoped eligibility and route conditions; they are not blanket exemptions.
BEFORE THE TRUCK ROLLS
Turn the estimate
into a permitted move.
Confirm the loaded measurements, carrier details, travel dates and exact pickup and delivery. We can help coordinate permits, escorts and route surveys around those facts.
