Legal load limits.
Legal Loads:

Length: Over all 75′ maximum for a truck and trailer.  Combination of 2 vehicles is  70′ and single vehicle and load is 45′ in maximum length allowed by state law.  They do have some restricted routes for size and routes for combinations.  For more information click here (.pdf).
Width: 8’ 6” wide.
Height: 13’ 6” tall.
Weight: 80,000 lbs. GVW, up to 13,000 lbs on steer axle, 11,000 lbs on a  single wheel or end of an axle, 20,000 lbs on a single axle, 34,000 lbs on a tandem axle.  For more restrictions see link above under “length”.
Overhang: 3′ in the front and 4′ in the rear.  Red flagged in daytime and red light at night.

Routine trucking permits.
Routine over-weight, oversize shipping, trucking and transport permits:

Length: Anything under 130′ long is routinely permitted.  They do have some stuff going on that is odd for some routes so call if you are close to this length.  Manufactured homes and mobile homes maximum is 80′ in length or 110′ combined as per Wisconsin state shipping regulations.
Width: Up to about 16′ in length for routine permits.  Anything over than is going to take time.
Height: 14′ is about the most you can get away with on routine permits and main routes.  The Wisconsin state shipping regulations are going to want to route you on Federal Highways.  If over 15′ 6″ expect possible permit delays depending on your route.  They seem to have no height limits but you have to be specific on your proposed routing and take them specific plan.  This is a good thing as you will probably NOT be required to do a route survey as they are pretty organized on their maximum height capabilities.

Weight: They have frost laws in effect from March 15 – May 15 so confirm that it’s even possible to ship during these months.  Steer: 13,000, Single up to 20,000 lbs., up to 65,000 lbs. on Tandem, Tridem up to 81,000 lbs., Quadem, up to 90,000 lbs.  5 axles up to 100,000 lbs., 6 axle up to 166,000 lbs., 7 axle up to 182,000 lbs., 8 axles up to 191,000 lbs.  Over 150,000 lbs is a super load.  This is all depending on axle spacing and tractor configurations.
Overhang: Nothing specified so it’s a case by case basis.

Legal travel times.
Travel times and restrictions:

Sunrise to sunset applies with no half hour window stated.  Night time travel is permitted for loads under 100′ in length, 12′ in width and 13′ 6″ in height.  Travel on the weekend is allowed for all loads that are under 100′ long, 12′ wide and 13′ 6″ in height from Memorial day until Labor day..  All loads over these limits can only travel until 12 noon on Saturday from Memorial day and Labor day.  No travel is allowed from 4 pm until 11 pm on Fridays or Sundays.  No holiday travel on New Years day, Labor day, Memorial day, Thanksgiving day, Independence day and Christmas day.  If the holiday is on a Sunday you can not travel on Monday.  If the holiday is on a Saturday you may not travel on Friday.  IF you are on a humanitarian project you can possibly get the Wisconsin state shipping regulations to work towards your advantage and get the travel times lifted but don’t ask if it’s not a totally legitimate excuse.

When are pilot cars required.
Pilot Car and Escort vehicle information:

Length: 95′ to 110′ one rear pilot car (escort) is required.
Width: Loads over 12’ 6” some roads requires 1 (but not all), 15’ to 16’ feet in width needs 1 front on non divided highways or 1 rear on divided highways.  16’ to 22’ wide requires 1 police escort on some routes.  Non divided roads require 1 police in front, divided 1 police in rear.  You never know with this state as the same load may be able to run at a later date with a civilian escort.
Height: It all depends on your route with this state.
Weight: Check with the Wisconsin State of to see if your weight class will require a pilot car/escort.
Overhang: Who knows?

Notes:  Don’t bid on a shipment or plan on anything in this state without speaking with them first and make sure you get the persons name.  Permits are usually valid for 14 days or one trip which ever happens first.
