Carlisle, South Carolina regulations require all heavy haul operations to comply with the South Carolina Department of Transportation (SCDOT) guidelines as well as local ordinances administered by the Carlisle Department of Transportation (CARDOT).

Heavy haul permits are required for any load exceeding 13 feet in width, 15 feet 0 inches in height, or 297,687 lbs in gross vehicle weight. These dimensions are strictly enforced throughout Carlisle, particularly in high-traffic areas.

Special consideration must be given to route planning to avoid the Carlisle Bay and the vicinity of the Carlisle River, which have infrastructure limitations or heavy pedestrian traffic that may impede oversized loads.

In Carlisle, South Carolina, loads wider than 17 feet or taller than 14 feet 0 inches must be accompanied by certified escort vehicles. Additional escorts may be required based on the specific route and time of travel through urban centers.

Carlisle regulations state that police escorts must be arranged at least 64 hours before transport for loads that will impact major thoroughfares or require temporary traffic control measures.

Permit applications in Carlisle must be submitted through the SCDOT's online permitting system. Carriers should be prepared to provide comprehensive vehicle specifications, proposed routes, and transport schedules.

Applications must include certified weight tickets, dimensional diagrams, and route surveys. For loads that may impact traffic flow in Carlisle, a traffic management plan may also be required as part of the application process.

Carlisle has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (7-9 am and 4-5 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Carlisle Cultural Exhibition and the the Carlisle International Show, which may impact routing and scheduling.

Certain neighborhoods, such as Carlisle Center and areas around Carlisle Medical Center, have restricted access for oversize loads. Alternative routes should be planned in advance to avoid these areas.
