Legal size & loaded measurements
General width
8′6″Ordinary vehicle-and-load limit; safety-device, vehicle and load exceptions may apply.
Loaded height
14′Ordinary vehicle-and-load limit; listed exceptions and actual route clearances apply.
Legal size & loaded measurements
SDCL 32-22-3 publishes a 102-inch general width maximum with scoped exceptions. SDCL 32-22-14 publishes a 14-foot general height maximum with scoped farm, fire and baled-feed exceptions. South Dakota overhang legality and permitted envelopes depend on configuration, product, wheelbase and load. South Dakota weight legality requires complete axle, spacing, tire, bridge, posting and route analysis.

Permits, routes & larger loads
The applicable permit
Movement above the legal baseline requires the applicable South Dakota permit product; an application does not guarantee approval.
Permits, routes & larger loads
Allow additional agency review above 200,000 pounds, when overweight and over 12 feet wide, or above 16 feet high. Extended-period and annual products retain their named eligibility and envelopes; exact configuration, route and issued authorization control.
State permit fees
Single-trip agency fee example
$25 for this South Dakota 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 Dakota'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.

Single-state pricing uses the mileage you enter. For a proposed route and intermediate states, use the route calculator.
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. Depending on the road or permit conditions: A front escort is required above 10 ft on the specific Black Hills highways listed in ARSD 70:03:01:20(2). A separate list uses an over-16-ft threshold. Match the actual highway segment before booking. Depending on the road or permit conditions: Escorts or flaggers are required when the load leaves less than a 10-ft passing lane, projects over 2 ft into an adjacent lane, or forces traffic onto the shoulder. Turns, bridges and overhead clearance can also require traffic control.
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. Depending on the road or permit conditions: Escorts or flaggers are required when the load leaves less than a 10-ft passing lane, projects over 2 ft into an adjacent lane, or forces traffic onto the shoulder. Turns, bridges and overhead clearance can also require traffic control.
Travel hours & road restrictions
Travel hours
Interstate nighttime travel is unavailable when an escort is required, width exceeds 10 feet, height exceeds 14 feet 6 inches, or listed single-unit/combination lengths are exceeded. Other-highway oversized night travel is limited to named LCV, emergency and national-defense products; current calendar, weather and permit terms still control.
Travel hours & road restrictions
Current closures, construction, postings, weather, local restrictions and issued route conditions must be checked immediately before movement.
Signs, flags & safety equipment
Safety equipment
Use red/orange flags at least 18 inches square on every oversize load and on all corners above 8 feet 6 inches. Above 95 feet long, above 12 feet wide, or at night, display front/rear 18-by-84-inch signs legible at 500 feet. Night projection lamps/reflectors and cargo securement remain cumulative.
What the driver needs
Prepare the driver packet
Carry every permit in the permitted vehicle and present it to law enforcement on demand. An LCV requires the original signed permit; other support-document and media rules remain product-specific.
Special equipment & permit programs
Special vehicle programs
The handbook separately defines overwidth baled-feed/solid-waste, custom-harvester, stack-mover, farm-machinery dealer, manufactured-home, construction-equipment, electric-utility, LCV, emergency and national-defense paths with distinct envelopes, fees, duration and operating conditions.
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.
