Wyoming frost law restrictions.

2020 Wyoming frost laws, seasonal load weight and speed restrictions.

Special Note: Oversize loads are not permitted to travel when a “no unnecessary travel advisory” is issued. An enroute load may proceed to (or return to) the nearest parking area or town. At no time shall the load continue beyond these points unless approved by the Wyoming Highway Patrol.

A partial view of Wyoming’s extensive table of restrictions including weight restrictions during periods of spring thaw is shown in the following figure:

Last Update 04/26/19

Class II Roadway and Posted Road restrictions remain in effect in Zones 1 and 2, AND FOR STH 54 AND STH 173 IN WOOD COUNTY.  Class II Roadway and Posted Road restrictions will no longer be in effect in Zones 3, 4, and 5 as of 12:01 a.m., Thursday, April 25, 2019The Frozen Road Period

Three distinct programs take advantage of the frozen pavement and sub-base conditions during the winter months and protect pavement’s weak conditions during the springtime freezing and thawing period.

These three programs include:

  1. The frozen road declaration that is normally in effect from mid-December to late February or early March.
  2. The Class II roads – typically lasts from early March until the first or second week in May.
  3. The springtime posted roads program normally from the second week in March until late April or early May.

All three of these programs apply only to the state highway system. Local county or township road maintenance authorities are responsible for determining when their roads are either frozen or thawing and whether sections should be posted for weight limitations. Questions related to weight restrictions on local or county roads should be referred to the maintaining authority for those roads. Regional transportation offices can be contacted to answer specific questions related to the state highway system in their region.

Call (608) 266-8417 for a recorded message of the status of road weight restrictions.

Washington frost law restrictions.

2019 Washington frost laws, seasonal load weight and speed restrictions.

WSDOT may impose load and speed restrictions when freeze-thaw or other conditions may subject the roadway to damage from normal traffic.

• Emergency Load Restrictions – Applied to any road when the untreated pavement layers (base course and sub‑grade) are supersaturated and unstable.

• Severe Emergency Load Restrictions – Applied only to a roadway whose surfacing depth is insufficient to resist subgrade swell pressure or is surfaced with a thin bituminous treatment. When restrictions must be imposed: post the road with appropriate signs, notify Commercial Vehicle Services, and provide courtesy notices to principal road users as circumstances allow.

Spring Load Restrictions – Timing and Duration:

It is the Department’s position to not implement Spring Load Restrictions any earlier than necessary. The Department monitors the daily high/low temperatures at numerous locations throughout the state. The high/low temperatures are used to calculate accumulated freeze and thaw indexes. The Department relies heavily on the existing highway conditions and experience of its field personnel when making the final decision of when to implement and remove load restrictions. When posted, axle weights may be restricted to 6, 7, or 8 tons and are identified by color on the Load Limit Restriction Map found at the Web page below.

Pennsylvania frost law restrictions.

2019 Pennsylvania frost laws, seasonal load weight and speed restrictions.

Pennsylvania DOT mostly publishes restrictions by district: https://www.penndot.gov/RegionalOffices/Pages/default.aspx

You can also check pendotnews twitter and restrictions map https://www.511pa.com/

Seasonal postings are used in cases where the road’s structural analysis indicates permanent postings may not be necessary as in the case of the freeze/thaw damage cycle.

Penn DOT Publication 23, Chapter 15, defines the Freeze/Thaw Period as: “The calendar period between approximately February 15th and April 15th, during which times the temperature results in changes (weakening) to the structural strength of the road surface. Additional restrictions may be required by the POSTING AUTHORITY due to severe weather and other unforeseen circumstances.” A search of the website produced no specific guidelines or requirements for reductions in axle weight.

Hauling authorized by an Letters of Local Determination (LoLDs) shall be prohibited during the Freeze/Thaw Period unless a modification is specifically

requested by the User and approved by the Posting Authority. The User must confirm the effective dates of the Freeze/Thaw Period with the District.

North Dakota frost law restrictions

2019 North Dakota frost laws, seasonal load weight and speed restrictions.

North Dakota DOT has not published any frost law updates since:

Order 2019-10 Effective 4/24/2019 7:00:00 AM CT

For the latest updates, check North Dakota Load Restrictions

NDDOT’s procedure for initiation of spring load restrictions on the State Highway System is based on the following factors: The state:

Uses load restrictions to reduce damage to roadways caused by heavy loads at a time of year when highway pavements are most vulnerable.

Sets load restrictions as weather and roadbed conditions require and removes these restrictions when roadbeds are stable enough to carry legal weight traffic without damage based on the following sources of information: temperature probes in the base layers of pavement sections, long range temperature forecasts, and a Falling Weight Deflectometer (FWD) that measures the strength of roadway bases and the asphalt pavement surface.

Using the map (select Load Restrictions Proposed) determine the color of route of interest and refer to the table for axle weight limits (see below).

North Dakota Load Restriction Chart (2019)

Using the Ton Mile Fee Schedule you can determine the price per mile for the overweight fine. These permits can range from 500$ to well over 10,000$ so pay attention to the weights. If in doubt about how the weights should be distributed click here (Insert a call to action for our axle spacings calculator)

This chart will allow you to calculate your overweight costs per trip. There are 2 possible ways you can be charged. Gross Vehicle Weight and Axle Group Weight. You can be charged per group and also the over all GVW, and these charges must be combined to create an accurate permit charge.

Simple Example of how 1 permit can cost 4200$ if you are just driving through ND on the interstate and your loaded GWV is 132K. You’re allowed 48K on your group of 3 (tridems) and your weight is 56K on your two groups of 3, and are legal on your steer (56K +56K=20K=132K). You would need to go to the 3rd chart labeled “Triple Axle Weights” and find your respected weight (the road you referenced in the map). For this example we are going to use “Highways Restricted by Legal Weight” you would look to the side of 56K and In this example you would be charged 4$ per mile per group you travel in ND, resulting in 8$ per mile traveled.

You then have to go to the first chart labeled “Ton Mile Fee Schedule” For GVW, find 132K on the chart and in this example it would be 6$ per mile traveled at this weight. You would then take the 8$ a mile (4$ per tridem group at 56K) + 6$ a mile GVW to receive a total of 14$ per mile in overweight charges. If you travel 300 miles in North Dakota that would cost you 4,200$ in overweight permit fees during frost laws.

New York frost law restrictions.

2019 New York frost laws, seasonal load weight and speed restrictions.

No apparent restrictions. The department of transportation may issue restrictions when conditions dictate. No information is easily available on seasonal weight restrictions. New York does issue restrictions to all tractor-trailers during periods of snow and snow removal on major highways. The New York Winter Travel advisory is available at: <


For up-to-date road conditions and restrictions, go to New York’s “Improved Winter Travel Advisory” service at: https://511ny.org/.

Annual Road Postings Underway on Sections of NH State Highways
Heavy Vehicle Ban Necessary to Protect Pavement During Thaw.

New Hampshire Department of Transportation of Transportation Commissioner George Campbell has ordered customary spring load limits on sections of the State highway system as authorized under State law.

Warmer weather means sections of roads will be vulnerable to pavement breaking up as the frost leaves the underlying road base. Road postings are determined annually by local NHDOT District Engineers, who carefully review each roadway in their areas before posting a road limit to ensure protection of the roads. For up-to-date road conditions and restrictions, go to: http://newengland511.org/ and select “trucking” at the top of the page and “New Hampshire” at the top of the map.

The maximum allowable vehicular weight on posted sections of State highways is one half of the regularly allowed legal load (RSA 236:3-a).

Affected roads can be found on the Web at https://www.nh.gov/dot/media/nr2011/nr03222-roadpostings.htm

Nevada frost law restrictions.

2019 Nevada frost laws, seasonal load weight and speed restrictions.

Nevada is somewhat ambiguous on frost and thaw travel restrictions. One reference suggests “Frost Laws” are in effect from February 1 through (about) April 30. Nevada provides a map (frost law map), but it is lacking details or any substantive guidance.

Nevada’s online DOT site is less than informative on this topic.
