Why Do Heavy Loads Require Permits?

Non-divisible cargoes larger than the permitted dimensions limits for trucking companies in Canada and other countries require oversize load permits. These dimensions limits, however, vary considerably from one state, county, and town to the next.

Even the methods used to determine permit prices—whether based on the load size, tons of weight, weight increments, per mile, or a combination of these factors—vary significantly from state to state. For example, the price of Missouri oversize permits varies from that of Florida oversize permits. You are aware of the significance of this knowledge because you want this procedure to go as smoothly as possible.

Why choose the right oversize permit?

A wrong permit might have devastating effects when it comes to organizing the transportation of any apparatus, materials, or things classified as oversize or super loads. Three effects of utilizing the wrong permit type include enforcement action, travel restrictions, and wasteful payments. For this reason, all trucking companies in Canada need to acquire oversize permits when transporting heavy loads.

Not all items that must be transported across the country fit neatly into a trailer or a rail car. Some items necessitate the knowledge of a transportation company experienced in transporting enormous cargoes due to the vastness of their size. These kinds of tasks call for the assistance of heavy hauling firms.

Restrictions Particular to Oversized Loads

Highway Traffic Act requires heavy haul transport businesses to get an oversize/overweight permit whenever the size or weight of a vehicle exceeds the typical legal thresholds. When organizing a movement that exceeds the HTA’s legal boundaries, consideration can be given to alternative forms of transportation, including rail, air, or sea. However, while attempting to transfer huge loads across provincial routes, heavy haul trucking companies in Canada and Ontario must ensure they comply. That entails a maximum load width of 3.85 meters on multilane highways and 3.7 meters on two-lane highways. No load may exceed 12.5 meters for single vehicles and 25 meters for combination vehicles. Furthermore, nothing can be transported above a height of 4.26 meters, regardless of length. Additionally, there may be weight limits.

Obtain the state permits to get the job done

All heavy haul carriers transporting oversize loads into the US states must submit the online application and get a permit regardless of the amount of oversized load. Fines for rules violations or failure to get permits can cost thousands of dollars. You risk violating your permits for breaking the rules, deviating from your designated route, or travelling during prohibited hours. You must get an Oklahoma oversize permit to enter the state; the permits are valid only for three days. 

Any oversized or overweight vehicle (including cargo) that exceeds the permitted size and weight on Florida state roadways must be moved with a Florida oversize permit. Any vehicle/vehicle combination that exceeds the permitted truck dimensions and configurations is not allowed to move without permission, except for a few legally exempted vehicles. Heavy haul trucking businesses may need to satisfy additional standards before being granted authorization to operate and receive an oversized/over-dimensional permit. Examples of this could be ensuring they comply with the National Safety Code or having their CVOR (Commercial Vehicle Operators Registration). Additionally, businesses transporting such cargoes across borders must follow similar procedures and obtain the necessary permits in the states of the USA and Mexico.


In actuality, many transportation-related businesses might be challenging. Police guards and the use of pilot cars may be necessary, depending on the size of the load. The shift requires extensive planning since surveys and routing must be completed beforehand to verify that the route can support the extent of the load. For an oversize load to reach its destination, vehicles carrying heavy loads should also fit below any bridges that may come across. All trucking companies in Ontario must comply with the state’s transport rules and acquire the right oversize permit.
