Requirements for extra heavy or extra legal/dimensional (superloads) in SK.
Typically so we’re not publishing too much information a superload is defined by Saskatchewan Province as any shipment with weights and dimensions that exceed those published above in “Routine Permits”. There are exceptions but everything depends on proposed routing and road/weather conditions and if frost laws are in effect.
Required flags and markers for oversize/heavy-haul shipments loaded onto truck trailers.
Know how to mark your load and what signs are required by your permit.
Lights, flags and markers:
If over 120.078 inches wide (3.05 meters) you will need amber lights for night running and flags for daytime travel. A WIDELOAD or “D” sign is required for all wideloads over 120.078 inches wide (3.05 meters) however a “OVERSIZE LOAD” banner is NOT allowed. If you are moving at night any required banners must be illuminated with additional amber light in the center of the rear. If over 10′ 9″ (3.2766 meters) wide the cab of the tractor must be mounted with an amber light. If over 82 feet (24.9966 meters) long you MUST have a “D” sign or LONG LOAD banner mounted on the rear. If not transporting a load you must cover ANY signs.
NOTES: Lift axles are not permitted. Flip axles can be used if trailer king pin to center distance is is less than 45′ 5″, the trailer is no longer than 53′ and the load is classified as NON DIVISIBLE. A tractor wheelbase from the center of the steer axle to the center of the drive axle can not measure over 244″ unless you permit the load with a longer wheelbase AND IF they approve it. This only applies to oversize permits and overweight will not be eligible. A tridem drive tractor is NOT recognized by the Province of Saskatchewan except for moves that are large and NON DIVISIBLE, IF a tridem drive tractor IS allowed it MUST have a wheel base of no less than 260″ and no greater than 268″. A spread axles trailer that has axles spacings of greater than 6′ is considered a single axle for weight calculations and is not allowed to carry more than a combined total weight of 20,000 pounds or 10,000 pounds per axle. EXCEPT when in the case of when the object being shipped is NOT over 37,500 pounds loaded on the spread. Please leave Saskatchewan experiences below. This is a tough Province to get solid numbers out of and our viewers can use your experience to help them.
Will your shipment be delayed do to frost and thaw law restrictions?
Frost and thaw laws constantly change due to weather conditions in Saskatchewan. Find out if there in effect:
Saskatchewan Province does have spring weight restrictions and the roads and highways are dependent on conditions. These restrictions usually apply to all secondary roads and not main highways. Overall weight reductions may be imposed in some areas. Check with Saskatchewan Province permit office for clarification.
