Legal load limits.

California DOT legal load size & weight limitations for 18 wheeler semi-trucks:

Length: Many measurements for semitrailers by California DOT seem very short because they’re referring to the distance from the king-pin to the rear axle.  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 of the trailer allowed is 53′ overall as long as it has two axles. If it has only one axle the maximum trailer length is 38′ overall. The maximum overall legal combination length is 65′ for the heavy haul and oversize sector of the trucking industry however there are additional laws for trucks pulling doubles or triples (dry box) that allows them to max out at 75 feet overall. California also has classifications such as a “STAA” vehicle. You can have a look at green truck dimensions at: Truck Map (.pdf)  for further clarification.
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 with no more than 12,500 on a steer axle, 20,000 pounds maximum weight on any single axle, 34,000 pounds maximum on tandem axles and on tridem axle configurations depending on axle spread such as from 10 feet to 10 feet 2 inches (10’2″) tridum is legal at 40,000 pounds. If you feel you are getting close to the legal limits see the section below on “routine trucking permits”.
Overhang: You are allowed 3 feet of front overhang (4 feet for fixed trailers ie; car haulers). 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. Note: The comment below on vehicle shipping overhang. We welcome your comments below to help others in clarification of rear overhang.

Routine oversize and heavy haul trucking permits.

Oversize and heavy haul trucking permits that are routinely issued by California DOT:

Length: 135 feet in overall length is the maximum length on a routine oversize trucking permit that is issued. All others see “superload” info below or learn more about the California length limitations.
Width: 15′ wide is the maximum width issued by a routine oversize trucking permit in California. All others see “superload” info below or learn more about the California width restrictions.
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. Some shipments may be forced to use a lowboy, double drop or otherwise trailer that is purposely lower to the pavement.
Weight: 250,000 pounds maximum (Class C if over or see super loads). Steer axles 12,500 pounds. Single axle; 20,000 pounds, 46,000 pounds on tandem axles, 60,000 pounds on tridum axles. Quadem axles are not recognized  for over weight shipments. Depends upon the axle spacings and tire size. Trunnion: 60,000 pounds. Gross Weights: 5 axles is 112,000 pounds; 6 axles – 117,450; 7 axles 158,000 pounds, 8 axles 181,300 pounds (subject to inspection). The weights depend upon the number of tires combined with the overall distance between each of the axles. Spacings on axles are tricky in this state. The California  DOT permits office will consider a number or factors but primarily bridges. If weights are excessive and trailer capabilities are even close to short of maxing out forget it. Pavement structural and stress testing and results will govern your overall capabilities. Learn more details on California heavy haul weight restrictions.
Overhang: Overhang in the state of California is very detailed depending on amount of front or rear overhang and the route (color; see maps link above). Some shipments may be forced to be loaded onto stretch trailers. See the above folder on left titled “California overhang in depth” for more information.
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 feet and 6 inches is documented as 9 feet.

California overhang in depth:

California 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 18 feet tall will require a route survey. If 18′ feet or over in height you more than likely will be classified as a superload. For detailed information on California maximum height limitations check out the state height limitations and routes.
Weight: Of course heavy haul weights are a huge issue. Anytime your overall GVW is over 80,000 pounds or you exceed any of the above (see routine permits) limitations on length, width or height depending on the route you desire you are subject to be classified as a superload.
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.

California permitted travel times and restrictions for heavy haul and oversize loads:

Let’s start by clarification of daylight hours; the basic rule is 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 or escorts are required.

Shipments requiring escort vehicles or pilot cars:

Length: If over 100′ in length in the city of Los Angles or Los Angeles county 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 feet and no longer than 135 feet 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 you will be required to have 1 front pilot car on 2 lane roads or 1 rear escort on 4 lane roads however note 2 pilot cars are required on some routes. Any shipment in excess of 12 feet should figure on a minimum of 2 pilot cars or escort vehicles.
Height: Once you hit the 18 feet mark in height everything changes. You’ll be required to have a height 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 18 feet and 3 inches (18’3″) as well as a utility company clearance letter. Anything over this height will be required to notify all utility companies in advance of transport.
Weight:  There is little mention of weight restrictions and pilot cars. As with many states if the shipment is able to maintain the minimum required speed limits then a pilot car or escort vehicle may not be required. If your shipment is not able to meet the minimum speed requirements then you will more than likely be required to have at minimum 1 front and 1 rear pilot car/escort vehicle and in some cases may even be required to have a police escort. This is based entirely on your proposed route, the weight of the heavy haul shipment and ultimately the California heavy haul permit department.
Overhang: It all depends on the route. Just as a basic rule to calculate off of (not legally binding) 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 (30′ 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 for oversize and heavy haul trucking in California. California state shipping regulations continuously change due to construction, project completions and policy modifications. Always refer to your oversize trucking permit before traveling.

Pilot car and escort vehicle 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: Inour professional opinion all pilot cars and escort vehicle operators have items in addition to the above:  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 flags, lights and 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.

2021 Federal Bridge Formula Weights Explanation.

2021 Easy – Federal Bridge Formula weights explanation.

The Federal Bridge Formula explanation.

Heavy-haul truck drivers should know exactly how to calculate the Federal Bridge Formula. Below is a very simple explanation to ensure compliance.

Explaining the maximum weight any combined set of axles on a truck and trailer can carry to cross a bridge on the Interstate highway system.  The following Federal bridge formula is used for calculating acceptable weights:

W=500 [ LN/N-1 + 12N + 36]

W= the overall gross weight on any group of two or more consecutive axles the the nearest 500 pounds.

L= the distance in feet between the outer axles of any group of two or more consecutive axles.

N= the number of axles in the group that are under consideration.

How do I determine Bridge Formula?

THIS IS A PERFECT EXAMPLE: Bridge formula is 30 times the wheelbase* in centimeters plus 18,000 kg.

*Wheelbase in the above Bridge Formula calculation refers to the maximum axles span (center of the first axle to the center of the last axle of any axle group) in a heavy commercial vehicle.

Axle spacing is another consideration that must be taken into account when looking at the Federal weight compliance laws.  In order to properly protect our bridges the number and the spacing of truck and trailer axles carrying the shipment must be calculated.  So a bridge weight formula applies when the gross weight on 2 or more consecutive axles exceeds the limitations on the formula, except that the 2 consecutive sets of tandem axles may carry a gross weight load of 34,000 pounds each if the overall distance between the 1st and last axle is  over a 36 feet minimum.

Exceptions to the Bridge Weight Formula:

There are exceptions.  Federal law does include an exception to the Federal Bridge Formula and the bridge table. 2 consecutive sets of tandem axles may carry 34,000 pounds each IF the overall distance between the first axle and last axles of these tandems is 36 feet or greater.  For example:  a 5 axle tractor semi trailer combination may carry 34,000 pounds of weight both on the tractor tandem (axles 2 and 3) and the trailer tandem (axles 4 and 5), provided the axles 2 and 5 are spaced at least 36 feet from each other.  Without this exception the bridge formula would allow for actual weight of only 66,000 pounds to 67,000 pounds on tandems spaced 36 feet to 38 feet apart. (References: U. S. Department of TransportationFederal Highway AdministrationFederal Bridge Formula Weights” – FWHA-FBFWHA-FBFF the .pdf)

Note:  In addition to the above formula weights Federal law says that a single axle is limited to a maximum of no greater than 20,000 pounds and that axles that are closer than 96 inches from each other are limited to a maximum weight of 34,000 pounds.  Also that gross vehicle weight be less than 80,000 pounds.

Federal law (23 U.S.C. 127) does include an exception to the Federal Bridge Formula and the Bridge Table—two consecutive sets of tandem axles may carry 34,000 lbs. pounds each if the overall distance between the first and last axles of the tandem axles is 36 feet or more. For example; a five-axle tractor and semitrailer combination may carry 34,000 lbs. pounds both on the tractor tandem (axles 2 and 3) and the trailer tandem (axles 4 and 5), if axles number 2 and 5 are spaced at least 36 feet apart. Without this exception the Federal Bridge Formula would allow an actual weight of only 66,000 pounds up to 67,500 pounds on tandems spaced 36 to 38 feet apart.

Heavy haul trucking, pilot cars and permits.

Locate heavy haul, oversize equipment shipping companies, pilot cars and ordering trucking permits in Alaska:

 

Legal load limits.

Length:  53’ Trailer Length
Width:  8’6”
Height: 14’
Weight: Depending on route 80,000 lbs GVW.
Overhang: 3’ in the front, 4’ in the rear.

Kenworth double trailers in compliance with 80,000 pounds GVW laws.

Alaska requires any shipment over the weight of 80,000 pounds to have a special trip permit.

Routine trucking permits.

Trucking oversize and overweight permit limits:

Length: Shipping varies due to routing and season.
Width: Shipping rules vary depending on route and seaason.
Height: Over 14′ and once again everything varies depending on routing and season.
Weight: Single; 30,000 lbs, tandem; 56,000 lbs, tridem; 70,000 lbs, quadem 80,000 lbs, gross weight; 150,000 lbs. Depends on the route you wish to travel, distance and the bridges you intend on crossing.
Overhang:  20′ is a safe number but once again everything up here is seasonal as roads are closed or combined with weight frost laws may be in effect and limit you.  For the most part there is no such thing as a “routing” shipment in Alaska.

Notes:  When between the months of October 1 and March 31 for 1, 2 & 3 drive axle groups on truck tractors intending to travel the Dalton, Elliott or Steese highways between Fairbanks and Prudhoe Bay you can shift your legal axle weights to make them legal. The following weights on these routes apply: single; 22,000 lbs with 8′ 1″ minimum spacing between axles, tandem; 42,000 lbs, tridem; 48,000 lbs maximum.

When a pilot car is required.

Pilot car (escort vehicle) requirements:

Length: if overall length exceeds 85′ you are required to have 1 pilot car (escort). If overall length exceeds 100′ you are required to have 1 front and 1 read pilot car (escort).

Width: If 10′ to 12′ wide you will be required to have 1 pilot car (escort vehicle). If width exceeds 12′ and up to 14′ you are required to have 1 front and 1 rear pilot car (escort vehicle). From 14′ to 18′ in width you will be required to have 3 pilot cars. 2 front on 4 lane and 2 rear on 2 lane roads with the additional at either end. 18′ up to 22′ in width will require 4 pilot cars (escorts); 2 in front and 2 on the rear. If over 22′ in width you will be required to “close and roll” (closing the road as you move) requiring you to have 5 pilot cars as well as a minimum of 1 police escort.

Weight: You may be required to have a pilot car/cars if you are not able to maintain the minimum speed limit and on some designated bridge crossings depending on your weight class.

Overhang: If overhang is greater than 20′ you will be required to have 1 pilot car vehicle. If over 35′ you will be required to have 1 front and 1 rear pilot car.

Required shipment markings & flags.

Truck, trailer and shipment required signs, banners & flags:

For loads that are over 8′ 6″ in width you will be required to have a “OVERSIZE LOAD” banner on the front or your truck and on the rear of your truck or load, whichever is most practical. Flags must be a minimum length of 16″ and be safety orange or red in color.

Frost and thaw laws.

Frost and thaw laws:

Frost and thaw laws are in effect usually from March 1 until mid June on major routes, southern central and the interior. There are so many roads that have different regulations on thaw laws and frost laws. You absolutely will want to call the Alaska State DOT office at the number below for more information.

All of this depends entirely on the route you choose to travel as well as distance and any bridges that you intend to cross. It also depends upon the length, height and width of the shipment. Between the months of October 1st and March 31st for one, two and three drive axle groupings on trucks and truck tractors traveling the Elliott, Steese and Dalton highways between Fairbanks and Prudhoe Bay you can shift legal axle weights in the following weights on these routes in applicable: single axles 22,000 pounds (with 8’1″ minimum axle spacing). Tandem axles 42,000 pounds, tridem axles 48,000 pounds. The maximum height allowed is 15’3″. Shipments over 14 feet wide or 150 feet long or 16’6″ in height must supply to the permitting department the exact route they wish to travel.

Heavy haul and oversize truck signs and flags.

A standard oversize load sign is required on the front of the tractor and the rear of the shipment if it exceeds 8’6″ and width. The sign must be yellow and have a minimum of 48 inches in width with black letters that are 10 inches tall and 2 inches wide. Acceptable signs when specified shall read “oversize”, “oversize load” or “wide load” for over width vehicles and/or shipments “oversize”, “oversize load” or “long load” for over length vehicles must be affixed to the rear of shipment when overall load exceeds 60 feet in length. Vehicles and loads with rear overhang exceeding 10 feet are subject to the following: must have “oversize” or “oversize load” signs and a amber high intensity rotating, flashing, oscillating or strobe type beacon which must be visible for a minimum of 500 feet from the end of the shipment. You must have either an extended light-bar or a rear pilot car or escort vehicle. All flags must be a minimum of 16” square and must be red. Flags are required to be on vehicles with loads wider than 10 feet and if overhang exceeds the legal limits in any direction.

Pilot car and escort vehicle requirements.

If the width of the shipment is over 10’6″ and up to 12 feet one pilot car or escort vehicle is required. For lengths over 85 feet and up to 100 feet one pilot car is required. If overhang is greater than 10 feet but less than 20 feet one pilot car or escort vehicle may be used. It is possible to use an extended lightbar and place of a rear pilot car. Heavy haul or overweight shipments with special bridge conditions are required to have two pilot cars if the width is 12 feet up to 14 feet to pilot cars or escort vehicles are required if the length is greater than 100 feet to escort vehicles or pilot cars are required. If the overhang exceeds 20 feet unless the rear is greater than 35 feet or the front greater than 60 feet one pilot car is required. For widths over 14 feet three pilot car vehicles or escort’s are required: two in the front and one in the rear. If you have overhang from the rear that is greater than 35 feet to pilot cars are required and for widths up to 18 feet but not more than 22 feet 4 pilot cars or escort vehicles are required. If road closures exist and you are an excess of 22 feet wide then you will be required to have 5 escorts or pilot cars. You may be permitted to use an extended light-bar when up to 20 feet of rear overhang and lieu of a rear pilot car.

Pilot car and escort vehicle requirements.

Pilot cars and escort vehicles may be passenger trucks and cars as long is they are under 10,000 pounds in total weight. Pilot cars and escort vehicles must carry commercial vehicle insurance. Pilot cars and escort vehicles will not carry any passengers. Pilot cars and escort vehicles will not act as a steer man or a tiller man for any load. Oversize load signs and beacons: all escort vehicles and pilot cars are required to be equipped with the appropriate signage. Depending upon the shipment you are working with this might be oversize, wide load or long load and the sign must be roof mounted with a high intensity rotating flashing oscillating or strobe type amber beacon light which must be visible from a minimum of 500 feet in any direction. When a pilot car or in escort vehicle is required to lead any oversize load the appropriate sign must be faced towards the front of the pilot car or escort vehicle when the pilot car or escort is chasing a load the appropriate sign must be faced towards the rear of the vehicle. Pilot car companies and escort vehicle drivers shall carry the following items and equipment at all times when escorting heavy haul and oversize loads: a 24 inch stop slow paddle sign, three bidirectional emergency reflective triangles, 15 pound rated B and C fire extinguisher, a reflector rise orange vest shirt or jacket, a first aid kit, a flashlight with extra batteries, a red cone and be equipped with a red hand flag.

Do I need a trucking permits? Legal load limits.

Ohio maximum load limits until a trucking permit is required:

Length: The Ohio DOT has no maximum length set that we know of. Trailer length is set at a maximum length of 53 feet. If the shipment is over 90′ in length (combined) 1 pilot car (escort vehicle) is required.
Height: 13 feet 6 inches is the maximum allowed shipping height as per Ohio DOT without a permit.
Width: 8 feet 6 inches is the maximum width allowed to travel on Ohio roads.
Weight: 80,000 pounds maximum weight (GVW) 20,000 pounds on any single axle, 34,000 pounds on dual axles, 48,000 pounds on tridum axles.
Overhang: 53 feet is the maximum length. Front overhang is an issue that has not been clearly addressed by O
Notes: Definitions of weights: Overall Spacing: Distance center to center, to the nearest foot between extreme front and rear-most axles of vehicle or combination of vehicles, or any internal axle grouping. Spacing: Distance center to center, to the nearest foot, to an adjacent axle.

 

Some divisible loads may be permitted to travel is less than 150 miles. Transporting metal coils such as aluminum, copper, steel have different laws, basic info is 3 (or fewer) coils are deemed “nondivisible loads” (as per OH NonDivisible and per Ohio 5501:2-1-01 (Q).

Routine oversize and heavy-haul trucking permits.

These maximum dimensions/weights are routine oversize or heavy-haul trucking permits in OH:

Length: Anything over 90′ will require a pilot car/escort vehicle.
Width: 14′ is the maximum width considered on routine issued permits. Routing of course is the restricting factor so if you may qualify for up to (our approximation) 16′ routinely depending on your desired route.
Height: 14′ 6″ in the maximum for routinely issued permits. Of course routing is the qualifier. If your shipment is 14′ 6″ or over you will be required to have a high pole escort.
Weight: Single axle: 29,000 lbs. Tandem axles: 36,000 lbs if axle spacing is a minimum of 4′ 1″ and up to a whopping 50,000 lbs if  your axle spacings are more than the 4′ 1″ but not more than 16′. Tridem axles: 60,000 lbs maximum if your axle spacing is less than 4′ and 53,000 lbs if your axle spacing is more than 4′ but less than 16′. Quadem: 60,000 (as long as GVW is not over 120,000 lbs). 5 axles (single-tandem-tridem): 29,000 lbs – 46,000 lbs – 46,000 lbs = 121,000 lbs maximum total per group of axles.  However; in order to do this you have to have a minimum of a 51′ outer bridge and a 36′ inner bridge in order to heavy haul on a 5 axle setup. 6 axles: (single-tandem-tridum); 29,000 lbs, 46,000 lbs, 53,000 lbs = 128,000 lbs total maximum per group of axles. 7 axles: (single-tridum-tridum); 29,000 lbs – 53,000 lbs – 53,000 lbs = 135,000 lbs total maximum weight allowed. 8 axles: (single-tandem-tandem-tridum); 29,000 lbs – 46,000 lbs -46,000 lbs – 53,000 = 174,000 lbs maximum for this kind of group setup.
Overhang: We have not located any information on routinely permitted overhang. So, we have to assume that as long as you do not want to overhang more than 1/3 of the overall length of the item being shipped you can probably get a routine permit. When you wish to exceed this basic rule (more than 1/3 overhang) you create a potentially dangerous situation. If you have any knowledge on routine overhang in Ohio please share it with others below.

80,000 pounds maximum weight (GVW) 29,000 pounds on any single axle, 36,000 pounds on dual axles, 60,000 pounds on quad axles.

Notes: As long as the GVW is not over 120,000 lbs you can use a tridem or quadem setup but you are required to have the minimum of 4′ 1″ spacing in your axles. You can go up to 132,000 lbs on a 7, 8 or 9 axle setup for your steering configuration plus 2 tridem or quadem axle groups. Please see more in superloads section below.

Notes: Definitions of weights: Overall Spacing: Distance center to center, to the nearest foot between extreme front and rear-most axles of vehicle or combination of vehicles, or any internal axle grouping. Spacing: Distance center to center, to the nearest foot, to an adjacent axle.



Ohio superloads.

Requirements for extra-heavy or over-dimensional (superloads) in OH:

Length: Depending on your route you probably will not have any problems with length in Ohio unless you are over 160′ overall. Ohio DOT has no set limitations on length so you may not even qualify as a supleroad.
Width: Again depending on the route you intend on taking unless you are over 18′ in width you may not qualify as a superload by the Ohio DOT. While they are not too keen on wideload shipments they tend to look at these on a case by case basis which is all dependent on your routing. In some areas you 16′ may qualify you as routine. If your shipment is over 18′ in width you will be classified as a superload. We welcome your comments below.
Height:
If you are over 14′ 6″ in the state of Ohio you will be required to have a high pole escort (pilot car) in front of you the entire route. Ohio DOT may require that you notify any/all utility companies that manage obstructions on your route before you are permitted to move. It’s all about your routing in Ohio as we are sure you are learning however, Ohio DOT is very knowledgeable and you have to give them credit for that. We feel they should be a little more lenient on height issues or have published routes for routine permits  but maybe they have future plans.
Weight: For superload configurations that are in excess of 120,000 lbs gross you will most likely be required to reduce your configuration by using a jeep. Your overall minimum axle spacings will need to be no less than 65′ with the inner bridge no less than 51′. See “routine trucking permits” above for more information about required axle group spacings as your groups need a distance of no less than 4′ 1″ between each.
Overhang: Use the rule of 1/3. Read more above in “routine trucking permits”

Legal travel times for oversize and heavy-haul loads.

Travel times and restrictions:

Basic travel times:
The basic rule of one half hour before sunrise and one half hour after sunset applies (example; travel start time is at 1/2 hour before sunset on approved days). Ohio DOT regulations travel times are complicated due to population/traffic density consideration. ALWAYS REFER TO YOUR PHYSICAL PERMIT BEFORE COMMENCING MOVEMENT. If your shipment is over 12′ in width you are NOT allowed to travel in the list of counties and within a 25 mile radius of the cities listed below between the hours of 6:30 AM until 9 AM and from 4:30 AM until 6 PM Monday thru Friday and on Fridays,  Saturdays and Sundays you may not travel after 3 PM during the days between April 1st until November the 30th.

Holiday movement:
You are permitted to travel on the following holidays with the above rules in mind; Columbus day, George Washington’s birthday, Martin Luther King day and Veterans day. You are prohibited from traveling on the following holidays; New Years day, Memorial day, Independence day, Labor day, Thanksgiving day and Christmas day. The Ohio DOT permit offices are closed on all of these days.

When pilot cars of escort vehicles are required.

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

QUICK REFERENCE

Length:

Width:
2 lane roads:

  • 13 feet requires 1 pilot car.
  • 14 feet and 6 inches requires 1 pilot car and 1 escort vehicle.
  • 16 feet requires 1 pilot car and 1 escort vehicle and 1 police escort.

4 lane roads:

  • 13 feet requires 1 pilot car.
  • 14 feet and 6 inches requires 1 pilot car and 1 escort.
  • 16 feet and 6 inches requires 1 pilot car and 1 escort and on some routes 1 police escort.

Height:

  • 14 feet and 6 inches requires 1 pilot car equipped with a high pole.
  • 14 feet and 10 inches and over requires 1 pilot car equipped with a height pole and 1 rear chase.
  • Some routes may be required to be accompanied by 1 police escort.

Length: 1 pilot car/escort vehicle is required in the overall length of your shipment is in excess of 90 feet in length.
Width: 1 pilot car/ escort vehicle is required for shipments in excess of 13′ wide. If on a 2 lane road the pilot car needs to be in the lead position and on 4 lane roads the rear chase position is required. If the width is greater than 14′ 6″ wide then you are required to have 1 front and 1 rear pilot car/escort vehicle.
Height: If the height of you shipment is in excess of 14′ 6″ in height you are required to have 1 front/lead pilot car/escort vehicle with a height pole. If the shipment is in excess of 14′ 10″ in height you are required to have 1 front pilot car/escort vehicle equipped with a high pole and 1 rear chase pilot car/escort vehicle displaying a “OVERSIZE LOAD” banner. See banner/sign specifications and requirements below in “pilot car certifications & requirements” section.
Weight: There are no immediate pilot car or escort vehicle requirements for shipments that are overweight. As long as the shipment is able to maintain the minimum speed limit requirements escort is necessary. This may not be applicable towards superloads which is on  case by case basis.
Overhang: Overhang, if excessive is reviewed on a case by case basis. If your shipment is overhanging by less than 1/3 of it’s length (1/3 meaning the overall measurement of only the item being shipped) you may be required to use a flag or amber light on the rear as long as the overall length of your shipment is not excessive and overhang is not either, ie; no more than 10′ (this is only a assumption and you must clarify your requirements with the Ohio DOT).
Note: If you are required to have only 1 pilot car/escort because your shipment is only 13′ wide but your shipment requires you to have 1 pilot car/escort because you are over 90′ in length you are considered a “combination” shipment and will be required to have 1 front and 1 rear pilot car/escort vehicle.

 

Pilot car certifications & requirements.

Pilot car (escort vehicle) certifications and requirements of the Ohio DOT:

Pilot car and escort vehicles operating in the state of Ohio are mandated by the Ohio DOT to have an amber light mounted on the roof of the vehicle. The amber light must strobe or flash and be clearly visible from a 360 degree angle from a distance of no less than 500′. The vehicle is required to have a single roof mounted sign or a front/rear sign (depending on if operating as a lead or chase vehicle) that is no less than 5′ in length and 12′ in height with letters no less than 8″ in height that are a minimum 1″ in thickness. The sign must be yellow in color with black lettering and state the nature of the load being shipping, either “OVERSIZE LOAD” OR “WIDELOAD”. All pilot car or escort vehicles are required to be equipped with a CB radio or powerful 2-way communication device that enables them to be in constant communication with all parties working in the movement. Pilot car vehicles are required to have a hand held paddle sign that states the words “STOP on one side and “SLOW” on the other is case traffic needs to be controlled.

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 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 and trailer markings.

Truck, trailer and shipment required markings with banners, signs and flags by Ohio DOT:

A strobing or flashing amber light that is visible from 360 degrees from a distance of no less than 500 feet is required to placed on the highest point of the cab of the tractor trailer. Signs/banners that indicate the nature of the shipment, “OVERSIZE LOAD” OR “WIDELOAD” are required to be placed at the overall front and rear of the shipment. These banners must be yellow in color with black lettering and not less than 7′ in width and 18″ in height. Letters must be a minimum of 10″ in height with a 1 1/2″ line thickness. Safety flags must be mounted at the 4 outer most corners of the overall shipment and be no less than 18″ in length in either direction and be safety red or orange in color. If the shipment protrudes in any direction like overhang additional flags are required. You may be required to place flashing or strobing amber lights on any protrusions as well.
