Mission, South Dakota regulations require all heavy haul operations to comply with the South Dakota Department of Transportation (SDDOT) guidelines as well as local ordinances administered by the Mission Department of Transportation (MISDOT).

Heavy haul permits are required for any load exceeding 11 feet in width, 15 feet 0 inches in height, or 250,352 lbs in gross vehicle weight. These dimensions are strictly enforced throughout Mission, particularly in high-traffic areas.

Special consideration must be given to route planning to avoid Mission Central Terminal and the vicinity of Mission Medical Center, which have infrastructure limitations or heavy pedestrian traffic that may impede oversized loads.

South Dakota law mandates escort vehicles for any load exceeding 15 feet in width or 15 feet 0 inches in height. When traveling through Mission, these requirements may be more stringent depending on the specific streets and neighborhoods traversed.

The Mission Department of Transportation requires a minimum of 37 hours advance notice to coordinate police escorts, which are mandatory for super-loads or when traveling through congested areas of Mission.

Permit applications in Mission must be submitted through the SDDOT'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 Mission, a traffic management plan may also be required as part of the application process.

Mission has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (6-9 am and 3-5 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Mission Spring Fair and the the Mission Holiday Festival, which may impact routing and scheduling.

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

The base permit fee for an oversize load in South Dakota is $40, with additional fees for super heavy loads (over 200,000 lbs) ranging from $150 to $350 depending on the complexity of the move.

For movements within Mission, Mission Department of Transportation may charge additional fees for city-specific permits, which can range from $75 to $500 or more for particularly complex routes or those requiring extensive coordination with city agencies.
