Blunt, 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 Blunt Department of Transportation (BLUDOT).

Heavy haul permits are required for any load exceeding 13 feet in width, 13 feet 0 inches in height, or 256,644 lbs in gross vehicle weight. These dimensions are strictly enforced throughout Blunt, particularly in high-traffic areas.

Special consideration must be given to route planning to avoid Blunt Civic Center and the vicinity of Blunt Bridge, 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 14 feet 0 inches in height on highways and certain city streets. The South Dakota State Police often require escorts for loads that are particularly large or heavy.

For movements within Blunt, the Blunt Department of Transportation may mandate police escorts for oversize loads, especially during peak traffic hours. Scheduling these escorts requires advance notice, typically at least 65 hours prior to the move.

The South Dakota Department of Transportation manages the primary application process for oversize permits, with supplementary permits required from Blunt Department of Transportation for transit through Blunt limits.

Required documentation for Blunt permits includes axle configuration diagrams, proof of insurance with appropriate coverage levels, and detailed transport plans. Engineering assessments may be required for loads exceeding standard weight thresholds on certain streets and bridges.

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

Seasonal restrictions apply during major events like the the Blunt Film Exhibition and the the Blunt Winter Fair, which may impact routing and scheduling.

Certain neighborhoods, such as Blunt Center and areas around the Blunt Bay, 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 Blunt, Blunt 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.
