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

Escort vehicles are required for oversize loads exceeding 14 feet in width or 15 feet 0 inches in height on highways and certain city streets. The South Carolina State Police often require escorts for loads that are particularly large or heavy.

Parker has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (6-9 am and 4-5 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Parker Holiday Exhibition and the the Parker Food Games, which may impact routing and scheduling.

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