Saskatchewan Trip and Fuel (IRP / IFTA) Permits

The SGI Permit Office can issue the following permits to non-Saskatchewan carriers:

Single Trip Permit Registration

Can be purchased over the phone if paid by credit card. This doesn’t apply to Term Permits or permits issued through SGI’s Self-Issue Permit

Program.

Can be purchased if the carrier is not part of the International Fuel Tax Agreement (IFTA)

Fuel Tax reporting is required from all inter-jurisdictional trucking firms that travel in Saskatchewan with commercial motor vehicles that have a gross vehicle weight of 11,797 kilograms or more.     

Inter-jurisdictional trucking firms must apply for an International Fuel Tax Agreement (IFTA) license to report and account for Fuel Tax payable and distances traveled in each jurisdiction in which they operate. 

To get a single trip permit, contact:

Phone: 306-775-6969

Toll free: 1-800-667-7575 (in Saskatchewan)

IFTA membership

Out-of-province carriers who are IFTA members do not need to purchase a Single Trip Fuel Tax permit. To become a member, contact the Ministry of Finance at 306-787-6632 or 306-787-7749.



Saskatchewan Overweight / Oversize Fines

Highway Officers are the primary law enforcement members responsible for enforcing transport regulations for commercial vehicles, including those for weights and dimensions, on provincial highways. If vehicles are found to be overweight, drivers/carriers can be charged for the overweight violation. Overweight charges can be very large fines and driver/carriers need to be aware of the consequences for hauling overweight. The Highways and Transportation Act outlines the consequences (fines) for being found in an overweight situation. Overweight fines are based on the amount of weight vehicles are over the legal limits. The fines for vehicle operators can vary from not less than one hundred dollars ($100) to not more than five hundred ($500).

WEIGHT

FINE

For exceeding allowed weight

$35 plus $10 each 110 pounds or fraction thereof over legal weight

Running Hours and Holiday Restrictions

Warning Lights

For night movement vehicle must have amber lights visible from the front and side at the outermost extremities. The rearmost edge of the projecting load must be marked with a red lamp visible from the rear and sides.

Not specifically mentioned, but it is anticipated that the standard red and white "D" sign is also acceptable.

Flag Requirements

Flags must be displayed on all four corners of all overwidth loads and at the extreme ends of all protrusions, projections or overhangs.


Flags, Lights and Banners

Travel is allowed on weekends. Travel not restricted on holidays. No movement from 3:00 pm Friday until Monday morning.

Saskatchewan Tire Regulations

In Saskatchewan, it is possible that you could be operating your vehicle for at least five months of the year in winter driving conditions from November to March but snow tire law gets no traction in Saskatchewan.

The government of Saskatchewan will not consider making winter tires ( chains ) mandatory. In some other jurisdictions, the arrival of winter weather means drivers must install snow tires. Tires lose pressure at the rate of 1 lb./inch2 for every 5° C drop in temperature. The minimum allowable tread depth is 1.6mm ( 2/32” inches in fraction ).

Tire width in Saskatchewan is 445 mm. The weight limit for single tires with a width of 445 mm (17.5”) or greater increases to 7,700 kg (from 6,000 kg) for single axles and to 15,400 kg for tandem axle groups. An under-inflated tire results in wear on the outer edges of the tread surface. On a wet road surface, an under-inflated tire will not squeeze the water out from under the tire surfaces as well as a correctly inflated tire will. If the tire is under-inflated, it has more chance of riding up on a film of water (hydroplaning). The amount of traction with the road surface would be greatly reduced, in turn reducing steering control. Never mount bias and radial tires on the same axle. Always ensure tire diameters are within 12.5 mm (1/2 in.) of each other on a set of duals.

Saskatchewan Frost Laws

Typically, seasonal (spring) restrictions take effect in March.

Spring Load Restrictions on affected highways: The maximum load on steering axles is 10 kg per millimeter (560 lb. per inch) width of tire (manufacturer's stamped dimensions), to a maximum of 3 000 kg (6,612 lb.) on each wheel but to a maximum of 5,500 kg (12 120 lb.) on the steering axle; except for straight trucks on primary highways which are allowed up to a maximum of 7,250 kg on the steering axle with the appropriate tire size.

Maximum loads on all other wheels will be limited to 6.25 kg/mm (350 lb. per inch) width of tire to a maximum loading of 1,650 kg per wheel (3,636 lb.)
