What Is An Oversize/Overweight Permit(s) For Trucks?

Commercial trucking is challenging since you must deal with a wide range of goods, some of which may be larger than is generally permitted. As a result, Simplex Group recommends learning about oversize/overweight licenses ahead of time for the safety of your business. Here is what you should know about oversize/overweight permit(s) for trucks:


An oversize/overweight permit is a form of paperwork required by a carrier when the dimensions or weight of a vehicle and its cargo exceed the Highway Traffic Act’s restrictions. Most highways accept oversize/overweight licenses. Obtaining extra permissions or authorization from the municipality may be necessary if you wish to drive on municipal roads.

If your vehicle or load cannot be decreased because it can’t be utilized for its intended purpose or function, or if dismantling it using adequate resources and equipment would take more than eight labor hours, you may request a permit.

Types Of Permits

Depending on the state, there are multiple types and subtypes of oversize/overweight permits for trucks. However, in the majority of the states, the leading four types of permits are:

1. Annual Permits

A commercial vehicle can be granted an annual permit, often known as a “blanket” permit, for a period of 12 months or one year. Yearly permits are generally subject to tight criteria and size/weight restrictions, which differ by state. Depending on the material you’re shipping, several jurisdictions additionally provide 30-, 60-, and 90-day licenses, as well as quarterly permits.

2. Superload Permits

When the dimensions and weights of an enormous load surpass the typical permit constraints, it is referred to as a superload. The dimensions and weights differ per state. A superload is distinguished from an oversized load because it cannot be broken down or split to lessen its size. A superload transport entails the transportation of extraordinarily massive and heavy equipment.

3. Project Permits

Project permits are for carriers that are working under a contract and transporting comparable cargoes, items, or buildings along the same route several times.

Depending on the term of the contract, project permits are valid for up to six months. Regular project permits and upgraded project permits are the two categories of project permits available.

4. Special Vehicle Configuration Permits

Vehicle and load combinations that are configured differently from those in the Highway Traffic Act require special vehicle configuration licenses. They are typically employed for experiments and pilot projects, as well as for vehicle combinations that require exemptions or specified configurations, weights, or dimensions for transit inside certain municipal or local territories.

Other jurisdictions may seek special vehicle configuration permits to allow something that is only authorized in specified regions or even to give temporary accommodation until the Highway Traffic Act and rules are changed.


Although many carriers are eligible, if your vehicle or cargo (or both) will be overweight and thereby your load is made up of more than one item, or if your vehicle or load is overheight, overwidth, or overlength due to the way you have loaded it, you may not obtain an oversize/overweight permit.

Also, suppose the vehicle or cargo is overlength. In that case, if the load is made up of more than one item, and the load’s rear overhang exceeds 4.65 meters from the center of the rearmost axle, you may not be qualified for an oversize/overweight permit.
