Do I need a trucking permit? Legal load limits.

Saskatchewan maximum load limits until a trucking permit is required.

Legal Loads:
Length: 75 feet (22.86 meters) overall long. Trailer length maximum is 53 feet (16.1544 meters).
Width: 8 feet 6 inches wide (2.5908 meters).
Height: 13 feet 6 inches (4.1148 meters) tall.
Weight: 12,100 pounds (5488.4677 kilograms) on steer axle, 20,200 pounds (9162.5659 kilograms) on a single axle, 37,400 pounds (16964.355 kilograms) on tridem axles.
Overhang: Kingpin settings and trailer wheelbase positions are important.  Call to clarify.

Routine oversize and heavy-haul trucking permits.

These maximum dimensions/weights are considered routine oversize or heavy-haul trucking permits in SK.

Length: Since Saskatchewan Province has no said length restrictions your overall length approval will depend on your proposed route.
Width: No set maximums, depends on routing.
Height: No set maximums, depends on routing.
Weight: Saskatchewan is tough.  No single axles numbers, 48,000 pounds (21772.434 kilograms) on tandem axles, 72,000 pounds (32658.651 kilograms) on tridem axles, if you are over 60,000 pounds (27215.542 kilograms) on tridem axles prepare for a bridge survey as it will probably be required..
Overhang: No set limits, depends on routing.

Saskatchewan superloads.

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.

Saskatchewan travel times and restrictions.

Make certain you don’t ship oversize or heavy-haul loads during restricted movement hours:

Travel times and restrictions:

Holiday restrictions vary, contact SGI permit office to see if you can travel or not.  Daytime travel only for loads over 82′ in length, 12′ 2″ in width and 16′ in height.  No movement is allowed on Friday after 3:00 pm from July 1 until Labor day.  Night time travel is permitted if under the above maximums but must have amber lights on all 4 outer most corners and reflective sign on rear indicating OVERSIZE or LONG LOAD.

When pilot cars or escort vehicles are required.

Heavy-haul or oversize loads may be required to be accompanied by a escort vehicle or pilot car if:

Length: If load is over 98′ on 2 lanes 1 rear pilot car (escort) is required.  If over 118′ in length 1 front and 2 rear pilot car (escort vehicle) is required.
Width: If a load goes beyond the center line of the road then 1 front escort is required.  If over 16′ 4″ wide you will be required to have 1 front and 1 rear escort.
Height: Up to the permit office depending on route.  If over 17′ 2″ in height you will be required to have a bucket truck travel with you.

Legal load limits.
Legal load sizes and weights:

Length: 60′ is the overall maximum length allowed without a permit.
Width: 8′ 6″ in the maximum legal width allowed to travel on state roads.
Height: 13′ 6″ is the maximum legal height allowed to travel without a permit.
Weight: 80,000 lbs maximum GVW is the maximum weight permitted to travel without a permit.
Overhang: 3′ in the front and 6′ in the rear is the maximum permitted overhang for legal travel.

Routine trucking permits.
Trucking permits for overweight and oversize loads that are handled on a daily basis:

Length: 125′ in length pretty much is the maximum for routing permits. 100′ in length is the maximum on mobile homes. Overhang see; escort requirements below but the maximum is about 15′ in length.
Width: 16′ in width is the maximum allowed on a routine permit. Over this width depending on routing and you may become a superload.
Height: 16′ in height is about the maximum. Anything over 16′ in height and you start to run into trouble. Any shipment that is over 16′ in height will be required to have a route survey done prior to getting a permit issued. Also your routing requires that the overall height of your shipment is a minimum of 6″ less that any obstructions on the route in order to get that route approved routinely.
Weight: Single axle maximum weight: 20,000 lbs, tandem axle maximum weight is 40,000 lbs, tridum axle maximum weight is 50,000 lbs, quadem axle maximum weight is 70,000 lbs, 5 axle maximum weight is 90,000 lbs, 6 axle maximum weight is 110,000 lbs, 7 axle maximum weight is 130,000 lbs. Anything over 130,000 lbs in weight is a superload and will need to have a bridge analysis done. See superload section below.
Overhang: 3′ in the front and 15′ of rear overhang is about all you are going to get. You can call for more information but expect trouble.
Notes: South Carolina DOT is pretty tough on shipments that exceed any of these weight/dimensions. So if you are a boat shipper you’d better figure out a way to cut that fly-bridge off, sorry and don’t shoot the messenger.

Superload information.
We have the following information available on superloads:

As far as length goes you can get some play as long as your routing keeps you away from historic areas. Width is the same thing with traffic density and population considered. Height is big trouble with the South Carolina DOT. You will be required to have a pilot car with you at all times if you are over 16′ in height for sure. Count on a full route survey for shipments over the 16′ in height and remember that they are NOT going to want to let you travel ANY route where the clearance is less than the required 6″ overage in height. So if you are 18′ in height then the obstruction on the proposed route needs to be a minimum of 18′ 6″ in height or you are going to have delays in getting your permit. Weight is a serious issue if you want to cross over ANY bridges so if your shipment is over 130,000 lbs in overall gross weight get ready for bridge studies and time delays. Our suggestion: examine routing alternatives. Overhang is a rare issue but when it comes up and you are wanting to overhang in excess of 15′ you are going to have trouble. This is the case anytime you want to exceed the basic rule which is more than 1/3 of the overall shipment length; you just don’t do it as it’s too dangerous and the South Carolina DOT knows it.

Permitted travel times and restrictions.
Permitted travel times and restrictions:

The 1 half hour after sunrise and 1 half hour before sunset rule applies. Travel is permitted Monday through Saturday with no travel permitted on Sundays. It is possible to get Sunday travel approved but the basic rule is “no travel on Sundays“. If you are allowed to travel on a Sunday it will be clearly stated on your travel permit.  You may not travel on the following holidays: New Years day, Independence day, Labor day, Memorial day, Thanksgiving day and Christmas day. You may not travel past 12 noon on the day previous of the holiday day and until after 12 noon on the day after the holiday. In high traffic density areas you are not allowed to travel from 7 AM -9 Am and 3 PM – 6PM if you are in excess of 14′ in width. If you are 16′ in width or over, on Saturdays you are only permitted to travel between the hours of 9 AM and 3 PM with no travel before or after permitted in any locations.

When pilot cars are required.
A pilot car (escort vehicle) is required when:

Length: Length is tricky in South Carolina, call the DOT to make sure. Leave your comments below for others please.
Width: From 12′ to 14′ in width will require 1 front pilot car (escort vehicle) on 2 lane roads. 14′ to 16′ in width will require 1 front and 1 rear pilot car (escort vehicle) on all roads in the state. If your shipment is over 16′ in width you will be required to have 3 pilot cars (escort vehicles) 1 front, 1 rear and 1 police escort in the rear.
Height: It all depends on your routing. You could be required to have a pilot car (escort vehicle) with a height pole the entire trip if you are 13′ 7″  (seriously). Please share your expertise with others below.
Weight: If you are approved for weight and able to maintain the minimum speed requirements the South Carolina DOT permit office will probably not require you to have a pilot car (escort vehicle).
Overhang: If your pulling a 48′ or a 53′ (just to clarify) long trailer and you have less than 15′ of overhang you can probably get away with flagging or amber lighting your shipment instead of a rear pilot car (escort vehicle). Anything over the 15′ mark and forget it you will be required to have a pilot car (escort vehicle).

Pilot car certifications.
Pilot car (escort vehicle) certifications & requirements:

The South Carolina DOT is pretty relaxed on pilot cars. You are required to have the proper banner/sign stating “OVERSIZE LOAD” or “WIDELOAD” displayed either prominently on the top of the vehicle or on the front of lead vehicles or rear of chase vehicles. You must have a flashing or strobing amber light on the top of the vehicle that is visible from 360 degrees from a distance of no less than 500′. You are required to have a CB radio or 2 way communication device and be in communication with all drivers working on your shipment. You are required to have your headlights turned on while working.

Note: It is only our professional opinion that pilot cars also have a minimum of the additional items but not required:  2 – 5 pound fire extinguishers type A, B and C, a paddle sign with the word “STOP” on one side and “SLOW” on the other with dimensions of no less than 18″ in diameter with a minimum of 6″ letters. A red safety colored flag with a handle no less than 18″ square, 3 reflective emergency road triangles or 18″ traffic cones, 8 burning road flares, 2 OVERSIZE LOAD banners (yellow with black lettering) and a safety colored (red, orange, yellow or lime green) vest, jacket or shirt (used while directing traffic).

Shipment, truck & trailer markings.
Truck, trailer and shipment required signs, banners and flags:

Amber lights: you are required to have 1 rotating or strobing rear amber light on any vehicle that is  shipping a load in excess of 12′ in width. Flags in safety colored orange or red with a minimum length in any direction of 12″ must be mounted on the 4 outer most corners of the entire overall shipment. Banner signs stating “OVERSIZE LOAD” OR “WIDELOAD” must be placed on the rear and front of the overall shipment. Banner signs must have a letter height of no less than 12′ and have a letter thickness of no less than 1 1/2″. Banner signs must have a yellow background with black lettering.
