The Saskatchewan Truckers’ Guide is for all types of trucking but also includes over-dimensional information issued by the Saskatchewan Ministry of transportation.  Very useful and thorough.
Canada Ministry of Highway and Infrastructure Weights and Dimensions Administration Manual.

Legal Loads
:
Length: 75′ overall long. Trailer length maximum is 53’.
Width: 8’ 6” wide.
Height: 13’ 6” tall.
Weight: 12,100 lbs on steer axle, 20,200 pounds on single axle, 37,400 lbs on tridem axle.
Overhang: Kingpin settings and trailer wheelbase positions are important.  Call to clarify.

Routine over-weight, oversize shipping, trucking and transport permits:
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 numbers, 48,000 lbs on tandem, 72,000 lbs on tridem, if you are over 60,000 lbs on tridem prepare for a bridge survey.
Overhang: No set limits, depends on routing.

Lights, flags and markers:
If over 102″ wide you will need amber lights for night running and flags for daytime travel.  A WIDELOAD or “D” sign is required for all wideloads over 10′ wide and “OVERSIZE LOAD” banner is NOT allowed.  If you are moving at night your banner must be illuminated with additional amber light in the center of the rear.  If over 10′ 9″ wide the cab of tractor must be mounted with an amber light.  If over 82′ 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.

FROST & THAW LAW RESTRICTIONS: 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.

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.

Pilot Car and Escort vehicle information:
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.
Weight: For over weight shipments it looks like an escort vehicle will not be required.
Overhang: Case by case basis.  Contact permit office for clarification.

Pilot car and escort vehicle requirements:
All pilot cars/escort vehicles must display a bumper or roof mounted “OVERSIZE LOAD” sign visible from both the front and rear of the vehicle. Sign must be at least 5′ long and 12″ in height, yellow in color with black letters no less than 10″ tall and 1 1/2″ in width. Vehicle must have 2 safety flags red or orange in color and be a minimum of 18″ of length and/or height mounted at a 40 to 70 degree angle on all 4 corners of the vehicle.

These signs must be no less that 8″ tall x 12″ wide and identity writing must be plainly legible. Vehicle must be equipped with a horizontally mounted rotating (or strobe) amber colored flashing light which must be visible from a 360 degree angle from a minimum of 500 feet. Vehicles must be equipped with a CB radio or 2-way communication device, 2 – 5 pound fire extinguishers type A, B and C, a 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.

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.

Legal load limits.
California DOT legal load size & weight limitations:

Length: Many measurements for semitrailers by California DOT seem very short because they are talking about the distance from the king-pin to the rear axle. So if you hear/see a small number make sure you get clarification. Also certain routes have restrictions on trailer sizes so if you are at any point confused please call the DOT and check California state shipping regulations before traveling. First of all for passenger related vehicles the maximum is 45′ in length overall on approved routes. Semi-trailers: for a single axle semitrailer the maximum length is 53′ overall as long as it has two axles. If it has only one axle the maximum is 38′ overall. The maximum overall legal combination length is 65′ for our sector of the trucking industry but for those who care to wager we will mention that there is some esoteric law for trucks pulling doubles or triples (dry box) that allows them to max out at 75′ overall.
Width: 8′ 6″ is the maximum with allowed to travel on any road in the state of California.
Height: 14′ in the maximum legal height allowed to travel in the state of California.
Weight: 80,000 lbs GVW. 20,000 lbs maximum weight on any single axle and 34,000 lbs on tandem axles is the maximum weight allowed in California without a permit.
Overhang: You are allowed 3′ of front overhang. Rear overhang is 6′ in most areas but can for sure be no more than 1/3 of the total item being shipped. Be sure to clarify the amount with the California DOT office you are traveling in to make sure. We welcome your comments below to help others in clarification of rear overhang.

Routine trucking permits.
Oversize and overweight trucking permits that are routinely issued by California DOT:

Length: 135′ in the maximum length on a routine oversize trucking permit that is issued.
Width: 15′ wide is the maximum width issued by a routine oversize trucking permit in California.
Height: Under 17′ as anything over that height is required to have a route survey. If your route happened to be a well documented  route you might be able to get away without having to do the route survey but its not likely.
Weight: Steering axle: 12,500 lbs. Single axle: 20,000 lbs. Tandem axles: 46,000 lbs. Tridum axles: 60,000 lbs. Quad axles: 60, 000  lbs (a quad setup is recognized by California state shipping regulations and the DOT as a weight reducer). 5 axles: 112,500 lbs. 6 axles: 117,450 lbs. 7 axles: 158,000 lbs. 8 axles: 181,300.
Overhang:

Notes: The distance between axles is measured to the nearest whole foot. When a portion is six inches you round up to to the nearest foot ie: 8′ 6″ = 9′.
Two consecutive sets of tandem axles can have a maximum weight of 34,000 lbs on each one but only if the distance between the first and last axles of the consecutive sets of tandem axles is greater than at least 36′.
The gross weight of each set of tandem axles must not be more than 34,000 lbs and the gross weight of the two consecutive sets of tandem axles is not over 68,000lbs. There is a lot to be said and read about what the California state shipping regulations and the DOT consider legal weights as far as axle groups and spacings are required. You can read more here. If you have anything to ad to this that can help others please share that information below.

Superload information.
California DOT superload information:

Length: If you are over 135′ in length overall you are more than likely going to be classified as a superload in California.
Width: Depending out routing and the number of lanes available on the route but 15′ in some areas would qualify you. Over 17′ in width and you will more than likely be categorized as a superload.
Height: Anything over 16′ as you know will require a route survey. If 17′ in height or over you are more than likely a superload. Check here to see if you are “black route” or “yellow route”. Then this is the California DOT (Caltrans) .pdf booklet for loads over 20′ in height which may just save your butt.
Weight: Of course weight is a huge issue. So we simply refer you to the “orange“, “green” and “purple” weight charts to get straight to the point.
Overhang: California is NOT going to let you break the rule of 1/3 (no more than 1/3 of overall length can overhang) and they shouldn’t in our opinion from a general view point. Get your proposed routing together and talk to them and see what you come up with would be our suggestion. 15′ possibly routine. 20′ and you are superload for sure we’d guess.
Notes: Here are some maps for superloads (California calls them “Extralegal” – maybe Arnie came up with that?)that can save you some serious money when you need the information. If you need to hire an expert to take care of your California shipping needs or even consult you we are happy to assist you. Most of the time we can handle your problem over the phone for a reasonable fee but when you need someone in the field we are qualified to assist you.  See consultation.

Permitted travel times & restrictions.
Caltrans permitted travel times and restrictions:

Let’s start by clarification of daylight hours; the basic rule of 1/2 hour before sunrise until 1/2 hour after sunset. If you do not require a pilot car/escort vehicle and are not overweight (green chart – over 52,000 lbs. on tandem axles or higher see charts in “superloads” section above) or don’t have anything out of the ordinary going on your travel times are 7 days a week 24 hours a day if you request to do so when you order your permits. The travel times restrictions are loaded so figure this as a rule of thumb (your permit will state your allowed travel times when issued) since this is just for you to get an estimate:

  • No travel from 6 AM until 9 AM in/around Los Angeles, San Diego, Sacramento & San Francisco.
  • No travel from 3 PM until 6 PM in the same areas with a 1 hour variance.

Your physical permit will state your exact allowed travel times when you get it issued and they will be real close to the above examples. There are simply too many variable to list.
Holiday travel:  There is no holiday travel time permitted in California unless you have a special arrangement with Caltrans. The following holidays are observed as no travel days by California state shipping regulations: New Years day, Abraham Lincoln’s birthday, George Washington’s birthday, Memorial day, Independence day, Labor day, Thanksgiving day and Christmas day. If the holiday is in a Friday or a Monday there is no travel permitted during Saturday or Sunday. Never travel without first verifying approval first which will be documented clearly on your permit.

When pilot cars are required.
If your shipment is any of the following you will be required to be escorted by a pilot car(s):

Length: If over 100′ in length in Los Angles area you will be required to have 1 front and 1 rear pilot car/escort. This may be required in other areas as well. If over 120′ in length on some routes you will be required to have 1 front and 1 rear pilot car/escort vehicle. If over 135′ in length you will be required to have 1 front and 1 rear escort on any road in the state.
Width: If your shipment is over 12′ wide the general rule is that you will be required to have 1 front escort on 2 lane roads or 1 rear escort on 4 lane roads. This 12′ rule pretty much applies until you get up to a width of 15′. At 15′ wide it is mandatory that you have 1 front and 1 rear escort. There are certain routes that will require you to have 1 front and 1 rear escort as well with only 12′ in width. Check with Caltrans to see if your route applies.
Height: Once you hit the 17′ mark that’s it. You have to have a high pole pilot car/escort vehicle and before you even apply for your permit you have to conduct a route survey with the pole set at a minimum of 17′ 3″. Anything over this is the same thing with utility companies notified in advance of transport.
Weight:  There is little mention if any of weight restrictions and pilot cars. As with many states if the shipment is able to maintain the minimum required speed limits there is usually not pilot car/escort vehicle required. If your shipment is NOT able to meet the minimum speed requirements then you will be required to have at minimum 1 front and 1 rear pilot car/escort and in some cases may even be required to have a police escort. Check with California DOT (Caltans) for further information.
Overhang: It all depends on the route. Just as a basic rule to calculate off of (NOT LAW) if you have less than 15′ of rear overhang you are probably not going to be required to have a pilot car. If you are dealing with a shipment that has 20′ – 25′ of overhang then yes you are going to be required to have at least 1 pilot car/escort vehicle – if overhang is in the front then lead and if off of rear chase. If you have both front and rear overhang that is in excess (20′ front and 25′ rear) count on being required to have 1 front and 1 rear pilot car/escort vehicle.
Notes: Keep in mind these are basic rules as of April 2013 intended to help you calculate requirements. California state shipping regulations has too many variations of policies, routes and regions to list anywhere but the state library. Always refer to your permit before traveling.

Pilot car certifications.
Pilot car (escort vehicle) certifications and requirements for operating in California state:

Pilot car (escort vehicles) are required to have a minimum of one flashing or strobing amber light mounted at the highest point if the vehicle. Light must be visible from 360 degrees from a distance of no less than 500′ and be completely covered when not tending a shipment. Pilot car vehicles must be equipped with a CB radio or a 2 way communication device with a range of no less than 15 miles and be in constant communication with all parties related to the shipment at all times while in transit. Vehicle is required to have identification signs on each side of the vehicle stating the company name, address and contact telephone number. Vehicle must be equipped with the appropriate banner/sign stating ‘OVERSIZE”, with “OVERSIZE LOAD”, “WIDELOAD” and “LONG LOAD” being used when appropriate that is a minimum of 5’ in width and 10″ in height with black lettering no less than 1 5/8″ letter thickness and a yellow background mounted no less than 48″ from the pavement surface. If not tending a shipment this sign must be fully covered or removed. Vehicle must have one safety colored red flag mounted on each side of the vehicle with a minimum distance of 16″ in either direction. Vehicles must also be equipped with a hand held sign with the words “stop” on one side and “slow on the other, a emergency colored vest/shirt/jacket with reflective stripe and a red emergency flag of no less than 24” in either direction.
Note: It is only our professional opinion that pilot cars also have items in addition to the above but not required:  2 – 5 pound fire extinguishers type A, B and C, 3 reflective emergency road triangles or 18″ traffic cones, 8 burning road flares, 2 OVERSIZE LOAD banners (yellow with black lettering) and a hard hat. Also when working in California you want to make sure you have the pilot car maps.

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

All trucking companies that are hauling oversize and overweight shipments must have a amber colored strobing or flashing light affixed to the top of the tractor trailer cab that is visible 360 degrees from a minimum distance of 500′. Signs that state the exact nature of the shipment; “WIDELOAD”, “OVERSIZE LOAD”, “LONG LOAD”, “EXCESSIVE FRONT OVERHANG”, “EXCESSIVE REAR OVERHANG”. If the shipment is over 100′ overall then the “LONG LOAD” sigh shall be displayed and the “OVERSIZE LOAD” sign is to be displayed for lesser lengths and other oversize configurations. The other signs will need to be used when appropriate. When shipping ANYTHING in excess of 80′ in length, 102″ in width or more than 10′ of overhang you MUST have the appropriate sign on the front of the tractor trailer and on the rear of the trailer and/or rear of overall shipment. The signs must have lettering that is a minimum of 10″ in height with a minimum of 1 5/8″ letter thickness with lettering being black in color on a yellow background. All shipments that are in excess of the 102″ must also have safety colored red flags placed on all for corners of the shipment that are no less than 16″ in either direction. Overhang must be flagged as well.  California law defines daylight time as 1/2 hour before sunrise and 1/2 hour after sunset which leaves you open for trouble on lighting which states that during the hours of darkness (we’ve got a 1/2 hour of lee-way time here) you must have 2 red lights on the side and rear (visible from a minimum of 500′) attached to the load or extremities. So, as soon as you pull out in the AM or if it gets close to dusk pull over and put on the red lights so you don’t find yourself in court trying to argue their error in defining “daylight hours” as it is a contradiction that our legal beagles caught while perusing their endless piles of regulations.
