Divisible and Non-Divisible Permits
The main difference between divisible and non-divisible overweight, oversize loads lies in their ability to be easily separated or divided for transportation purposes. Transporting both types of loads is regulated by state departments of transportation or other authorized agencies and requires special permits to be hauled on public roads.
Divisible Loads
By nature, divisible loads are those that can be divided or broken down into smaller, more manageable components for transportation. These loads can be disassembled, separated, or packaged into multiple parts without causing damage or compromising their functionality. Divisible loads are typically transported using standard vehicles and do not require specialized permits or regulations beyond regular weight and size limits. Examples of divisible loads include palletized goods, boxed items, or materials that can be easily split into smaller units.
Most jurisdictions have established specific weight and size limits for vehicles and their loads to prevent undue strain on roads, bridges, and other transportation infrastructure. These limits are typically based on engineering calculations and safety considerations. Divisible load permits come into play when the dimensions or weight of a load exceed the legal limits.
When a divisible load exceeds the state’s allowed size or weight limit, the carrier or transporter must obtain the necessary divisible load overweight permit from the appropriate regulatory authority before transporting it. This process typically involves submitting an application that includes detailed information about the load, such as dimensions, weight, route, and transportation equipment.
Non-Divisible Loads
Non-divisible loads are objects or structures that cannot be easily separated or dismantled for transport without causing significant damage or rendering them inoperable. These loads are generally too large, bulky, or complex to be divided into smaller components (taking more than 8 hours). Non-divisible loads require specialized equipment for transportation, such as flatbed trailers, cranes, or specialized vehicles. Due to their size and weight, non-divisible loads often exceed regular legal weight and size limits, necessitating special permits and compliance with additional regulations. Examples of non-divisible loads include large machinery, oversized tanks, industrial equipment, or structures like bridges or wind turbine blades.
Most jurisdictions have established specific rules and regulations that carriers must follow to ensure the safe transportation of non-divisible loads, often called super loads. Here are some critical aspects of non-divisible load regulations and permits:
Permitting Process: Carriers and transporters of non-divisible loads must obtain the necessary permits from the appropriate regulatory authority before transporting the load. The permitting process typically involves submitting an application that provides detailed information about the load, such as dimensions, weight, route, and transportation equipment.
Route Planning: Transporters of non-divisible loads must carefully plan their routes to ensure that the load can be safely transported without causing damage to infrastructure or posing risks to public safety. Route planning considerations include factors such as road conditions, load dimensions, bridge capacities, weight limitations, overhead clearances, and any other relevant safety considerations. They may need to coordinate with local authorities, utility companies, or transportation agencies to ensure that the chosen route can accommodate the load.
Escort Vehicles and Safety Measures: Depending on the size and nature of the non-divisible load, escort vehicles or pilot cars may be required to accompany the transport vehicle. These vehicles help manage traffic flow, provide advanced warnings to other road users, and ensure the safe passage of the oversized load. In most cases, the load itself may need to be marked with warning signs, lights, or flags to enhance visibility and safety.
Time Restrictions: Non-divisible load permits may specify certain time restrictions for transport. For instance, travel during peak traffic hours or on certain days may be prohibited to minimize disruption and congestion. Time restrictions may also be imposed to accommodate road maintenance or construction activities.
Compliance and Enforcement: Regulatory authorities and law enforcement agencies monitor carriers’ compliance with non-divisible load regulations. Violations can result in fines, penalties, or even the temporary suspension of the carrier’s permit.
